The agenda of Phase III training is geared towards someone with a more moderate knowledge and experience of motor controls, or who has had previous attendance at a Phase I/II class. This degree of training produces the highest level of benefits because the participant receives a blended content of some of our more enriched/technical products along with some real world instruction that is intended to build greater sales skills.

Did I mention that Sprecher+Schuh training is FREE?!?

All you have to do is get to Houston – and Sprecher+Schuh will do the rest by paying for your hotel and most meals for your four days and three nights stay (Sunday – Wednesday). The training takes place in Houston (TX) inside our training center only blocks from the hotel and IAH International Airport.

Phase III training goes beyond the basics of Phase I and the core of Phase II. Advanced topics are covered, including selling techniques specific to the electronics industry.

Logistical and background information on Phase III training is available through the Training section on the Distributor Extranet, as well as direct links to recorded versions of the basic and product training sessions.

Sprecher+Schuh takes pride in delivering quality industry training and we consider it an investment to grow your knowledge of motor controls. These training sessions provide the opportunity to ramp up earnings and boost your business sales by establishing specific sales strategies/techniques as they are associated with our products. The Marketing Dept. in Houston can also answer any questions that you may have related to Phase III training. Just give us a call. Please do not miss the one chance in 2017 to attend a Phase III training! Sign up now!

The PF Softstarter Controller provides intelligence, unmatched performance, flexibility, and diagnostics in a modular compact design for controlling either a standard squirrel-cage induction motor or a star-delta motor. Seven standard, and two optional, modes of operation are available within a single controller from 5 to 1250 amps.

PFS-0970-600V-120 800HP @ 480V AC

➌ Internal cooling fans:

All PF units include an internal cooling fan. The fan(s) run continuously to help keep the three Silicon Controlled Rectifier (SCRs) cool. During motor starting & stopping maneuvers, the SCRs generate an enormous amount of wattage (heat) which must be dissipated by the fans for proper operational life of the PF unit.

➋ Internal BypassContactors:

All PF units have a built-in bypass run contactors in each phase that is automatically pulled in when the motor reaches full speed. The bypass contactors from 3A to 480A have various physical forms. From 625A to 1250A, the PF internal bypass contactors incorporate the CA6 series contactors as shown.

➍ Internal cooling fan power terminals:

All PF cooling fans require a separate power source of 120VAC or 240VAC. From 5A to 480A the fan terminals are located on the line side. For 625A to 1250A, the PF fan terminals are located below the control module as shown.

➎ Silicon Controlled Rectifier (SCRs):

All PF units include back-to-back SCRs in each power pole which are used to control the voltage output to the motor. The PF controller incorporates a microprocessor to control the firing of the SCRs in the power pole section to provide full cycle control of the voltage and current to slowly and steplessly ramp the motor up to speed. Once at full speed, the internal bypass contactor closes and runs the motor at full voltage.

➊ Internal Overload & Diagnostics Protection:

The PF units include an internal overload and diagnostic protection which is accomplished electronically through three current sensors (CTs) providing feedback to the PF control module. The built-in overload can be set from Class 10 up to Class 30. Other selectable protection features include PTC, Ground Fault, Line Fault, Power Loss, Voltage Imbalance, Phase Reversal, Undervoltage and Overvoltage. ➋

RY2 Cadmium Contacts Eliminated

Replaced with Silver Nickle ContactsRelpol has stopped production of the RY2 relays made with AgCdO cadmium contacts and replacing with AgNi silver nickel contact material. This change is due to new 2017 European environmental directives where cadmium becomes a restricted material.

The current and voltage max contact capacities remain the same for these two types of material. However, the AgNi contacts do allow for a lower switching capacity over AgCdO. The AgNi switching minimum is 5mA@5V whereas AgCdO is 10mA@10V.

All other technical aspects of these relays are the same. All warehouses will continue to ship out existing RY2 AgCdO inventory until each are depleted by line item and replaced with the new RY2 AgNi contact material. This will be a transitional change until old stock is depleted over time.

Product Update: RY2 Relays

Theory And Operation Of Overload Protection Used In CEP7(S) Overload Relays

Question:• How do the CEP7(S) solid-state electronic overload relays

detect and react to overload conditions in a motor?• How can I reset the overload?• How quickly will the overload reset?

Answer:Theory Of OperationCEP7(S) solid-state relays have been designed to mimic a motor’s heating and cooling profile. Therefore, the motor’s trip and reset points are a function of temperature due to thermal input in the form of electric power.

The solid-state overload relay device duplicates the heating effect by using an internal capacitor and an algorithm on the circuit board. As the load current increases, the capacitor will charge up until an overload occurs and trips out the overload relay. Then the capacitor will discharge slowly, which would represent a normal cool down time in a motor before the motor can safely by re-started.

Resetting The OverloadCEP7(S) solid-state overloads can be manually or automatically reset but the device’s internal capacitor “remembers” the previous thermal level. Cycling the 3-phase power input will not reset the overload relay as doing so will not affect the operation of the capacitor. For example, you cannot force the capacitor to discharge faster to reset the overload relay quicker.

If the device is reset too soon, the overload relay will trip very quickly when exposed to an increased load if the motor has not had time to cool properly.

The normally closed contact can be re-closed in Manual Mode by pressing the Reset button. In Automatic Mode the normally closed contact is re-closed by the overload relay itself through an internal mechanism in the overload relay

Time To ResetThe automatic or manual reset function time varies but for general applications a 2 to 3 minute reset time can be expected. After this time period, the normally closed trip contact can be re-closed and starting of the motor contactor coil can be achieved by the control scheme used with the motor starter.
