1. GENERAL INFORMATION

The PN 150EVT SD (Slow Drop), PN-150EVT DPSD (Delayed Pick Slow Drop), and PN-150EVT DPSD-15 (15 sec. Delayed Pick Slow Drop) are programmable timer relays that apply quartz accuracy to timing functions. All are controlled by a microprocessor and its associated circuitry located on a printed circuit board within the relay enclosure. This circuitry ensures the relay’s timer functions are accurate and repeatable.

The PN-150EVT SD provides a programmable slow drop function that is field adjustable from 0.0 seconds to 52 minutes. Between 0.0 seconds and 59.9 seconds, the time is adjustable in 0.1-second increments. Between 1 minute and 52 minutes, the time is adjustable in 1-second increments.

The PN-150EVT DPSD provides a 5 second delayed pick and a programmable slow drop function that is field adjustable from 0.0 seconds to 52 minutes. Between 0.0 seconds and 59.9 seconds, the time is adjustable in 0.1-second increments. Between 1 minute and 52 minutes, the time is adjustable in 1-second increments.

The PN-150EVT DPSD-15 provides 15 second delayed pick and a programmable slow drop function that is field adjustable from 0.0 seconds to 52 minutes. Between 0.0 seconds and 59.9 seconds, the time is adjustable in 0.1-second increments. Between 1 minute and 52 minutes, the time is adjustable in 1-second increments.

The size and general appearance of the PN-150EVT relays is similar to most US&S PN-150 style relays. However, the PN-150EVT relays mount to the mounting base with two long bolts and the handle is in a fold down configuration (See Figure 1-1). The PN-150EVT relays can be mounted in the current US&S one-piece universal relay base with associated mounting hardware. Note that this is the universal, black thermoplastic polycarbonate base, and not the older Bakelite base.

For details on using the PN-150EVT relays as a replacement for a mechanical relay, such as the PN-150T, see Service Manual 6498.See Figure 1-1 for a photographic representation of major parts. Ordering references are shown in Table 1-1.

1.4. Controls, Indications, and Identification

1.4.1. Toggle Switches

Two toggle switches located on the face of the relay allow the user to program the timing interval in the shop or field without disassembling the relay, breaking the mechanism seal or disturbing internal adjustments. The toggle switches are enclosed by an independent, clear cover and secured with two screws.

NOTE

The cover screws are to be hand tightened only. The screws are considered installed when the screw heads lightly make contact with the cover plate.

This cover may be sealed using a relay seal to prevent tampering with the time settings and/or improper manipulation of the relay mechanism. Refer to Section 3 for instructions on programming the time delay.

1.4.2. LED Display

The PN-150EVT slow drop relays are provided with a large, easy-to-read, four character alphanumeric LED display located on the face of the relay. In operation, the display serves to indicate the status of the relay: deenergized, running, or picked. While programming the timing interval, the display prompts the user’s actions and indicates the preset timing interval. The LED display will also indicate error codes when hardware or logic faults are detected.

1.4.3. Identification

Each STS USA plug-in relay is provided with a nameplate indicating the type of device, part number and serial number. The serial and part numbers are engraved on this nameplate. An inspection sticker secured to the inside of the mechanism cover shows the operating values and serial number of the device.

1.5. Input Power

The nominal range of DC input power for the PN-150EVT slow drop relays is 9.2-30VDC, corresponding to a battery composed of 5-14 cells lead-acid or 8-22 cells nickel-cadmium.

The PN-150EVT slow drop relays have two inputs: control (9B+, 12B-) and local (7B+, 8B-). Local energy is used for various support purposes, including operation of the microprocessor, the LED display and associated circuitry. Control energy initiates the timing cycle. Both inputs require DC energy within the range of 9.2-30VDC (9.2-24VDC unfiltered full wave rectified AC). The combined local and control load is less than one watt while the relay coil is energized at 9-12VDC.



Circuitry is protected against damage from sustained voltage exceeding 33 volts by means of PolySwitches. A PolySwitch acts much like a fuse but, unlike a fuse, it will reset to a low resistance state when the input voltage is restored to the normal operating range. Local and control inputs are protected against polarity reversal.

1.6. Contact Arrangements

Three silver impregnated carbon (SIC) normally open contacts and a single independent normally closed contact are provided. A rear view of the plug in base is shown in Figure 1-2. This figure identifies each terminal by row (number) and column (letter) designation and function; it also presents the information in schematic form.

Figure 1-2 . Contact Arrangement



Figure 1-3. Contact Arrangement (Models with Test Jack) ("330X" suffix models only).

1.7. Relay Safety

The PN-150EVT slow drop relays conform to all applicable AAR recommendations for vital time element relays. The design of the hardware and software within this relay is such that any failure or combination of failures will cause the front contacts to open or remain open. Fail-safe design principles assure that under no circumstances will the front contacts close in less than the preset time delay following application of energy to the control input.



2. INSTALLATION

2.1. General Installation

The PN-150EVT DPSD (N40102502), PN-150EVT SD (N40102503), and PN-150EVT DPSD-15 (N40102504) include mounting kit (X40102001), which contains all the necessary hardware for proper installation. To install the PN-150EVT slow drop relays, use the following procedure. (Figure 1-1 identifies the parts involved in the installation and Figure 2-1 shows how these various parts fit together.)

1. Check the mounting kit to be sure it contains the mounting base (J780055), the aluminum mounting plate (M40101601) and its accompanying screws (J507295-0108), relay contact springs (M451142-2702), and 2 long mounting bolts (R451299-0104). The index plate (M40101902, M40101903, or M40101904) and the accompanying screws (J052246) are included with the individual relays.

2. Mount the indexing plate (M40101902, M40101903, or M40101904) to the mounting base with the screws (J052246) provided.

3. Screw the aluminum mounting plate (M40101601) to the back of the mounting base with the screws (J507295-0108) provided. The screws should pass through the smaller holes in the mounting plate.

4. Secure the mounting base to the relay rack. 5. Wire timer to specific application circuits. (Refer to Sections 2.3 and 2.4 for

contact receptacle spring, wiring and crimping information). 6. Insert the new relay (N40101702, N40101703, N40101704, N40103302,

N40103303, or N40103304) into the mounting base, continuing to hold the relay in place.

7. Secure the relay by inserting the mounting bolts (R451299-0104) through the holes on the front of the relay into the mounting base, and then screwing the bolts through the threaded holes on the aluminum mounting plate. The bolts should be tightened to 25 inch-pounds of torque.

8. The relay is now ready for programming.



Figure 2-1. Relay Mounting Diagram (PN-150EVT SD, PN-150EVT DPSD, or PN-150EVT DPSD-15)

2.2. Relay Indexing

Relays are factory equipped with indexing pins to prevent insertion of incorrect relays into a mounting base. Each relay has an indexing plate that is applied to the mounting base at the time of initial installation.

The following data defines the indexing that has been established for relays covered by this manual.

a. The index code always consists of four digits (such as 0001, 0002, or 0101) and is used for both the relay and the indexing plate on the mounting base.

b. The index code for each mounting base is determined by the placement of the holes in the numbered vertical rows of the large white nylon indexing plate which is affixed to the front of the mounting base. Never remove the indexing plate from the mounting base unless it is damaged or the indexing is to be purposely changed to accommodate a relay of a different part number. Discard the indexing plate which comes in a bag tied to the handle of all new relays unless it is needed for replacement of damaged indexing plate or for application to a new mounting base.



WARNING

Never drill new holes in a base indexing plate, which would permit the application of relays with a different part number.

Never change the indexing pins on the back of a relay unless it is being converted to a new part number.

Such tampering may compromise the safe functioning of the circuit in which the relay is used.

2.3. Receptacle Contact Springs

The one piece mounting base with hardware (X40102001) includes a full complement of receptacle contact springs (M451142-2702) to accommodate one or two #14 - #16 wires, mounting fasteners, and tags. It can also be equipped with receptacle contact springs for one or two #10-#12 wires (M451142-2703), or for one or two #18-#20 wires (M451142-2701). Make certain which type of solderless receptacle contact springs accompany the mounting base before proceeding with their installation. Inspect each solderless receptacle contact spring before proceeding with installation.

The following is recommended when installing solderless receptacle contact springs.

a. Receptacle contact springs must be inserted into the base with the lanced tab up.

b. Make certain that the lanced tab is slightly compressed as the receptacle contact spring is inserted along the top of the cavity. The lanced tab could have been bent during handling, and therefore might not provide the required contact pressure after the relay is inserted. If the lanced tab does not touch, slightly bend the tab by using your fingers or suitable tool.

c. After insertion, pull firmly on the wire to make certain the receptacle contact spring is locked in the mounting base.

2.4. Crimping Wires into Receptacle Contact Springs

Use the following procedure to ensure a good electrical and mechanical connection between the conductor wire and the receptacle contact spring. Table 2-1 identifies the correct crimping tool to be used when installing wires in receptacle contact springs.

Table 2-1. Crimping Tool Specifications

Crimping Tool Wire Size Receptacle Contact Spring

J397138 #10 / #12 AWG M451142-2703 J397139 #14 / #16 AWG M451142-2702 J397188 #18 / #20 AWG M4511420-2701



1. Strip 3/16 in. (0.187 in. or 0.47 cm.) of insulation from the end of the wire.

2. Place the receptacle contact spring into the jaws of the proper crimping tool. When using only one wire, use the shortest barrel.

3. Partially close the crimping tool jaws against the receptacle contact spring to hold it in place. (Do not crush the receptacle contact spring barrel at this time.)

4. Insert the stripped end of the wire completely into the receptacle contact spring barrel. Squeeze the tool handles until crimping is completed and the jaws release. When using both barrels, it is more convenient to attach the first wire to the longest barrel.

5. Remove the crimped receptacle contact spring from the tool and inspect the connection. Make certain that the wire is flush with the crimped barrel and that there are no loose strands of wire.



3. PROGRAMMING THE PICK-UP DELAY TIME

3.1. Slow Drop Delay Time The relay’s slow drop delay time is adjusted by using the two toggle switches located under the transparent cover on the face of the relay. Remove the two Fillister head screws holding the transparent cover in place to access the switches.

NOTE

The screw heads are drilled so that they can be wired together and sealed to secure the settings after the adjustment is made.

3.2. Adjustment Ranges

There are two adjustment ranges:

Low Range; 00.0 seconds - 59.9 seconds Adjustable in 0.1 second increments.

High Range: 0 seconds - 52 minutes, 00 seconds (0000-3120 seconds) Adjustable in 1 second increments.

3.3. Toggle Switch Functions

The upper toggle switch (SW1) (refer to Figure 3-1) is normally used to increase or decrease values on the LED display. When (SW1) is pushed upwards, it will increase the current value. When (SW1) is pushed down it will decrease the current value.

The lower toggle switch (SW2) serves the "ENTER" and "ESCAPE" functions. When (SW2) is pushed upwards, it activates the ESCAPE function. When (SW2) is pushed down, it activates the ENTER function.

Figure 3-1. Toggle Switch Functions

3.4. Field Testing the Drop-Away Delay Time

The delay time must be field tested whenever a PN-150EVT slow drop version relay is installed or replaced with a new relay. The purposes of the check are:

1. To ensure the user has correctly programmed the specified time interval.

2. To ensure that identical relays with different time delays have not been accidentally exchanged or misidentified.

Table 3-3 shows how to reliably field test the time delay setting.

4. CONTACT SPRING ADJUSTMENT

The following adjustment procedure should be used if the relay portion of the PN-150EVT slow drop relay has been replaced or repaired.

NOTE

The printed circuit board within the relay enclosure must be removed before using the following procedure.

CAUTION

These relays contain static sensitive components. Always observe proper ESD handling practices. Uninstalled circuit boards must always be contained in static-free bags. If these precautions are not followed, equipment damage may result.

4.1. Adjustment Procedure

The extension on the permanent magnet (Item 35 in Figure 7-2) should be adjusted so that it just touches the stop pin on the bottom of the armature with the nominal spacer, specified in Table 4-1, inserted between the main armature stop pin and the upper pole face. If necessary to obtain calibration values or contact openings, this spacer may be varied within the limits given in Table 4-1.

4.1.1. Adjusting the Front and Heel Contact Springs

1. Using the Test #2 values from Table 4-1, hold a gauge of the proper value firmly at the main stop pin by energizing the relay, adjust the front contact springs so that light is just barely visible between the contact tips. A 0.005 inch thinner spacer should allow the contacts to close. De-energize the relay and remove the gauge.

2. Remove the operating arm by slightly compressing the extreme front end of the heel spring and hold it clear from all heel springs. Adjust the heel spring members so that there is 0.005 to 0.010 inch clearance between the front contacts and the heel contact tips.

3. Replace the operating arm and work the armature by hand a few times to get the operating arm into its normal operating position. When replacing the operating arm, make certain that the same side is to the front, as reversing the arm may change adjustments because of slight warpages and molding tolerances. On later production arms the word "Front" is molded on one side.

4. Reinsert the Test #2 gauge used above, energize the relay and readjust the front contact springs as before.

5. Check that the Test #2A value allows the contacts to close.

4.1.2. Adjusting the Back Contact Springs

1. Using the Test #3 values from Table 4-1, hold a gauge of the proper value firmly at the stop pin by energizing the relay, adjust the back contact springs so that light is just barely visible between the contact tips.

2. Check that Test #4 allows the contacts to close. Again remove the operating arm and determine that the heel contacts have at least 0.005 inch opening at the front and back contacts as per Test #5C. If the operating arm is bumped while adjusting either the front or back contacts, de-energize the relay and position the operating arm by working the armature by hand a few times before proceeding.

3. A check must be made that when the front contacts are just touching, the back contacts have at least 0.020 inch opening as per Test #5A.

4. When the armature is in the fully released position, the front contacts must have at least 0.050 inch opening as per Test #5C.



4.2. Relay Calibration

4.2.1. Test Equipment Required

• 0-30 VDC Power Supply.

• DMM Fluke 77/87 or equivalent.

After the relay has been inspected and adjusted, it should be calibrated to meet the values given in Table 4-2. Before calibrating, the relay should be energized at the "charge" value and no higher, reversing the energizing polarity several times allowing the current to build up to full value in each direction.

4.2.2. Calibration Procedures

4.2.2.1. Polarity Test

Refer to Test #6 - Table 4-1.

The polarity should be checked as follows: Connect the negative power lead to the "+" or "+A" coil terminal, connect the positive power lead to the "-" or "-B" coil terminal. Energize the relay to "charge" value. The armature should not pick up. With the polarity of energization reversed so that the positive power lead is connected to the "+" or "+A" coil terminal, the relay should pick up. The "+" or "+A" coil terminal is the left-hand coil terminal on the relay as viewed from the front of the relay.

4.2.2.2. Drop-Away

Energize the relay with a charge that is four (4) times the pickup value. Decrease the current gradually until the armature drops, opening all front contacts. The value of current at this point should not be less than the value specified in Table 4-2 for Minimum Drop-Away.

Continue to gradually reduce the current and verify the back contacts are fully compressed (armature resting on the permanent magnet extension) at a current value not less than specified in Table 4-2 for Drop-Away with Full Back Contact Compression.



4.2.2.3. Pickup

Immediately after the drop-away current value is established, reduce the current to zero and pause with the circuit “open” for one (1) second. Apply current again in the same direction, gradually increasing its value until the armature moves away from the permanent magnet extension and picks up to close the front contacts. This current value should not exceed the value in Table 4-2 for Maximum Pickup.

4.2.2.4. Working

Obtain this value immediately after establishing pickup current by continuing to increase the current until the armature completes its motion and closes against the pole piece. The working current value should not exceed the maximum value specified in Table 4-2.

4.2.3. Check of Contact Openings

1. With the armature against the permanent magnet, there must be a front contact opening of at least that specified in Table 4-1 for Test #5B.

2. With the back contacts just closed, there should be a front contact opening of at least that given in Table 4-1 for Test #5A.

4.2.4. Permanent Magnet Hold-Down Force

With the relay in the normal upright position and de-energized, a force of at least 120 grams applied on the end of the bottom horizontal contact engaging pin of the operating arm should be required to cause the armature to move away from the permanent magnet (See Figure 7-2). This check should be made before and after the relay has been calibrated and after energizing with the charge value using normal polarity of energization.

Because of the allowable variation in the stiffness of the material from which the contact springs are made, the hold down force may vary between relays that have the same strength magnets. For this reason, on relays that have 275 grams or more hold-down force (using nominal spacers) replace one of the Phosphor Bronze screws (shiny nickel plating) that holds the magnet assembly to the pole piece with a tin plated steel screw (dull) J463078, which will shunt some of the magnetic flux. Bending the adjustable shunt away from the magnet slightly will raise the hold-down force slightly if necessary.

4.2.5. Contact Resistance

Resistance of front contacts should be measured with the relay energized and the armature against the stop pin. Back contact resistance should be measured with the armature in the de-energized position. Cleaned contact resistances must not exceed the values given in Table 4-3.

Type of Contacts Maximum Resistance Front Contac1

Maximum Resistance Back Contact

Silver-to-Silver Impregnated Carbon 0.09 Ohms 0.18 Ohms

4.2.6. Final Inspection and Test Procedure (Relays with Test Jack Only)

After the relay has been sealed, it must be examined through the cover and inspected, as follows:

1. Examine the contact springs for any evidence of disturbance from the original alignment. If a disturbance is found, repeat the adjustment and calibration procedures.

2. Examine the inside of the case for any loose particles. If found, open the case and remove the particles.

3. Check to ensure that the serial number on the calibration tag is the same as that on the name plate. If not, put the correct cover on the relay.

4. Check that all plated and painted parts are free from chipping, peeling or corrosion. The visual appearance must be acceptable and in accordance with accepted standards.

Perform the test procedure, as per Section 4.2.6.1 and Section 4.2.6.2.

4.2.6.1. Test Equipment Required • DVM capable of reading to four decimal places.

• 5000 ohm multi-turn potentiometer or multiple slide wire resistors.

• Test Jack (N322965).

After the relay has been inspected and adjusted, it should be tested to ensure it meets the values given in Table 4-4.

4.2.6.2. Procedure

Pick-Up and Drop-Away current of the relay may periodically be measured by making use of the test point on the coil and the internal voltage source, which supplies power to the coil. The measurements can be made with the relay in place or the relay can be removed and bench tested. Refer to Figure 4-1 if the relay is tested out-of-service.



1. Insert Test Jack (N322965), which has been placed in series with a milliamp meter and variable resister, into the test point labeled TEST, with the red lead up. Ensure that the lead is firmly seated between the test point contacts. This places the variable resistor and milliamp meter in series with the coil.

2. Set the resistor to 0 ohms. 3. Energize the relay and, after the relay picks, increase the resistance of the

resistor, while checking the current reading on the milliamp meter. Record the current value at which drop-away occurs.

4. Decrease the resistance and record the current at which pick-up occurs. 5. The recorded values should be within the tolerances given in Table 4-4.

5. RELAY FIELD TESTING

The PN-150EVT relay should be tested every four years to ensure it is working properly. The relay does not have to be tested in the shop but may be tested in the field.

5.1. Test Equipment Required

• 0-30 VDC variable power supply

• Voltmeter, Fluke 77/87 or equivalent

5.2. Test Procedure

1. Remove the relay from its base.

2. Wire the two EVT inputs in series to the power supply: The positive from the power supply should be wired to 7B+ (Local coil) and 9B+ (Control coil). The negative from the power supply should be wired to 8B – (Local coil) and 12B – (Control coil).

3. Turn the power supply on and adjust it to 24VDC. The EVT will energize in approximately 5 seconds for N40101702 and 15 seconds for N40101704 and the preset programmed dropaway time will displayed.

4. Gradually reduce the voltage on the power supply until the timer starts to countdown.

5. When the display counter reaches zero, the armature should drop. The minimum dropaway is 7.7 VDC. The display may remain lighted.

6. Continue to reduce the voltage on the power supply to zero and wait for the display to go dark.

7. Open the circuit from the power supply for a few seconds and reconnect the circuit. Gradually increase the voltage on the power supply to 9.2 VDC.

8. The display should illuminate with the preset programmed time and the armature should energize.

9. If the relay does not respond as expected, it must be returned to U&S for testing and/or repair.



6. TROUBLESHOOTING

If a PN-150EVT Vital Timer Relay exhibits a malfunction, use Table 6-1 to identify the symptom and possible cause of the problem.

Table 6-1. PN-150EVT Troubleshooting

SYMPTOM POSSIBLE CAUSE LED display is not illuminated. May include a loss of local energy or internal

electronic component failure. Return the unit to STS USA for evaluation and repair or replacement.

Repetitive error codes followed by timer shutdown. (Refer to Section 6.1 for error codes.)

May indicate a problem with relay logic or a hardware fault. Return the unit to STS USA for evaluation and repair or replacement.

Time delay not in accordance with desired value.

May indicate time delay programming error.

Undesired dropaway while control voltage is applied.

May indicate internal electronic component failure or intermittent control energy.

The ESCAPE switch is actuated but unit does not display “>60” prompt.

Verify control energy is not present. Momentarily remove unit from base to force system re-initialization. If problem persists, return the unit to STS USA for evaluation and repair or replacement.

In many instances, the source of trouble can be determined by close examination of the relay, its base, and associated wiring. To prevent unnecessary delay and expense of "No Trouble Found" returns to the shop or STS USA, include a brief explanation of specific conditions and type of trouble encountered when returning a defective relay. Such information is especially important in cases of intermittent trouble or where error codes are displayed.

The sealed mechanism cover must not be opened except by qualified personnel in a shop equipped to properly calibrate and test relays. Although removable without breaking the cover seal, the relay coil is internally connected and must not be detached in the field. All defective PCBs should be returned to STS USA for evaluation and repair. Relays exposed to moisture, electrical surges or mishandling must be returned to the shop or STS USA for refurbishment and retest.

6.1. Error Codes

Error codes appear on the LED display when logic or hardware faults are detected. All faults cause immediate termination of the timing cycle. If the timing cycle is complete, faults will cause immediate drop-away of the relay. The system will reset two seconds after the fault is detected. If nine consecutive faults occur without successful operation for at least one second, then the system will become dormant, stopping timing operation and maintaining display of the latest error code until local power is momentarily cycled off and on. Table 6-2 presents a list of possible error codes.

6.2. Frequently Asked Questions

Table 6-3. Frequently Asked Questions

TOPIC QUESTION ANSWER

Programming Switches

What if the programming switches are manipulated during a timing cycle or while the relay is energized?

Programming switch activity is ignored while the control input is energized. The timing cycle will not be interrupted nor will the relay drop if programming switches are manipulated while control energy is applied.

What if a programming switch is stuck in a position other than center?

Stuck programming switches will be ignored or unit will shutdown while display shows ">60" prompt.

What if both programming switched are actuated simultaneously?

This won’t cause any harm to the relay but may result in undesired results.

Time Setting

What if the time delay is set to 0000?

Relay will pick-up with zero time delay (pick-up delay of the relay mechanism is roughly 200-400msec, depending on factors such as control voltage, coil temperature and calibration variables).

Can the time setting be set to a wrong setting for a specific application? What prevents improper exchange of PN-150EVTs with different time settings?

No general purpose time element relay can protect against such errors. The user must program and test the time interval whenever a PN-150EVT is installed or replaced. Proper timing is assured only after the unit is tested while plugged-in and connected to the actual controlling circuit. Note that FRA rules 49 CFR 236.109 and 234.265 require the proper time setting to be shown on the circuit plans or the relay.

Could a fifth index pin be added to provide indexing protection for relays with different time intervals?

No. Addition of extra holes in the index plate could allow improper installation of relays having only four pins.

Should the time delay be checked with a calibrated timing device or chart recorder?

Timing may be checked with a stopwatch or wristwatch. Assuming a timing error of ±10% is allowable, the worst-case combined error of the PN-150EVT and an ordinary wristwatch would still be well within the 10% limit at the maximum interval of 3599 seconds (an error of 6 minutes per hour). Specialized time measuring devices are needed only where 0.1 second timing increment is significant or for the user’s convenience in making long interval measurements.



TOPIC QUESTION ANSWER

Display

What if individual LEDs or a row/column of LEDs is dark or dim?

Ignore unless digit(s) cannot be easily distinguished.

What if the display is intermittent, dim, unrecognizable, or otherwise incorrect?

Check list of status and error codes. Momentarily remove the unit from base to force re-initialization of system. Replace unit if problem persists. Return to STS USA for evaluation and repair.

What if the display appears frozen? Unit might be waiting for completion of a programming session due to accidental actuation of the ESCAPE switch. Momentarily remove the unit from base to force re-initialization of system. Replace if problem persists and return malfunctioning unit to STS USA for evaluation and repair.

Error Codes

What if the unit functions normally but frequently displays an error code?

Unit should be replaced at the earliest opportunity. Return to STS USA for evaluation and repair.

What if the unit displays an error code and appears to be locked-up, timing cycle will not run?

Note the error code. Momentarily remove the unit from base to force re-initialization of system. Replace unit if problem persists. Return to STS USA for evaluation and repair.

Local Voltage Input

What if local energy is switched on/off simultaneously with control energy?

Pick-up delay will be consistently extended exactly two seconds longer than the set time interval due to system initialization delay when local is first powered-up.

What if local energy is turned off while control energy remains on?

Timing cycle or relay will be cutoff after approximately one second. A new timing cycle will commence immediately upon restoration of local energy and completion of the two second initialization delay.

What if local energy is interrupted during a programming session?

Previous time setting will be retained.

What if local energy is coded at 75 or 240 ppm?

The PN-150EVT slow drop relays are intended to operate normally with the local input coded or steady. If coded, the code rate must be no less than 75 PPM with a 35% on-time.

What if local energy decreases to less than 9.2 VDC?

Although the control voltage must be 9.2 VDC or higher, the local voltage can be reduced below this value before operation is interrupted. A new timing cycle (or return to idle state) will begin once local energy is restored to at least 5-6 volts.

Control Voltage Input

What if control energy is momentarily interrupted?

Interruptions less than 250 milliseconds will not disrupt operation. Longer interruptions will cause the relay to drop and a new timing cycle to begin once energy is restored.

What if the units is removed from its base during a timing cycle or while the relay is picked-up? What if control and local energy are interrupted during a timing cycle?

A new timing cycle will commence once unit is reinstalled and/or energy is applied to the local and control inputs. By design, the PN-150EVT SD and PN-150EVT DPSD cannot extend time and there can be no residual effect caused by previous incomplete timing cycles.

What if the unit is subjected to Unlike electro-mechanical timers, no mechanical



TOPIC QUESTION ANSWER repeated incomplete timing cycles due to circuit design” What if a unit is subjected to frequent brief interruptions of control energy during a timing cycle caused by poor shunting of track circuits?

wear results from aborted timing cycles. Timer control circuits may often be simplified to take advantage of this characteristic.

What if control energy decreases to <9.2 VDC?

Same as effect of interruption of control energy.

Testing

Should pick-up and dropaway values be measured in volts or milliamps?

Pick-up and Drop-away operating values must be measured in volts since the control input resistance is non-linear (varies with applied voltage).

Should the local input be periodically tested to determine pick-up and dropaway values?

No. Local energy serves only to operate the processor and related circuitry. The control input is provided with a non-vital level-detecting (voltage sensing) circuit to maintain stable pick-up and drop-away at 9.2 VDC. Variations in local energy voltage have no effect on the operating values of the control input. Energy supplying the relay coil is derived solely from the control input.
