I. DESIGNATION

The Microprocessor Two Channel Thermal Controller MS8111-3F is designed forsimultaneous control of two temperature channels using proportional regulation. Each channelhas three outputs for control of the consumers (heating elements), powered by separate phasesof the grid, such as each output has a parameter "power factor". This allows via the controllerto adjust the power of the three-zone (front, middle, rear) of the upper and lower batch heatingelements of the baking chamber.

With the possibility to create zones with different temperature in the volume of thefurnace, depending on the construction characteristics and the requirements of thetechnological process, a homogeneous temperature field and even roasting of the product isachieved.

A timer is built into the controller, which after the start and end of the set-up time,activates a relay output which triggers an appropriate signalization, indicating the process'end.

IV. OPERATION

Basic parameters used in the device:• SP - setpoint• Zn – zone of proportionality (when positive – logic is in “heating” mode, when

negative – logic is in “cooling” mode)• PV - input parameter• AH - upper alarm limit• AL - lower alarm limit• F(I) - “power factor” for the two channels•

The principle of operation with "heating" mode logic is shown on figure 3 (below).

Фиг. 3Regulation law of a channel's output:

1. When input parameter is outside proportionality zone-

PV < SP – Zn

OUT ( I )=100.F ( I )128

, % (I=1,2,3)

2. When input parameter is outside proportionality zone-

SP – Zn < PV < SP

OUT (I )=100.F ( I )128

MS8111PWM3F can function in “cooling” mode, i.e. to control a cooling system. Inthat case, parameters Zn1 and/or Zn2 need to have a negative value (figure 4).

Фиг. 4The alarm output is common for the two channels and triggers independently of

which channel is in an alarm state, while on the respective channel’s display “ALL” and themeasured value alternate.

The timer is started via an external start/stop input. After it starts, its outputturns on for 1 second, after which it stops. The set time starts counting down, while on thefront panel the ALL LED starts blinking. After the time elapses, the timer output and ALLLED turn on permanently. This state lasts until externally stopped via start/stop button. Then,the output turns off and the timer awaits a new start – figure 3.

• The timer can be stopped while still counting down.

VI. CONNECTING TEMPERATURE SENSORSFor the sake of good functioning, it's important that the probes are located on a suitable

place in the environment, in which the temperature regulation will take place. When installingthem in an aperture, it is better to use a sealant, improving heat-transfer.

1. Connecting resistive sensors (Pt100 или др.)

The sensors can be connected through a two-wire line. Connecting two-wire sensors isdone like shown on figure 6 – between terminals 2 and 3 for channel 1, and terminals 4 and 5for channel 2.

2. Connecting thermocoples

When connecting a sensor - type thermocouple, care must be taken about the polarity ofthe sensor. If polarity is inverthed, the device's readings will be incorrect.

When working with thermocouples, it is necessary to use a compensation cable,corresponding to the type of thermocouple used (Figure 7).

Figure 7

VII. CONNECTING THE REGULATOR’S OUTPUTSConnecting a controller output, depending on the one selected in the request code way to

execute the corresponding digital output, to the load (operating circuit of the correspondingswitch) according to the schematics shown on figure 8.

VIII. CONFIGURING THE SETPOINTSThe mode is accessed by pressing and holding the SET button for more than 5 seconds.

While pressed, the display shows the values of the setpoints. If released too soon, access to configuration is not granted.

When in configuration mode, the lower displays the parameter’s name, while the upper - its value. Editing is done with buttons, while switching to the next parameter is done with [SET].

With a short press of the SET button, the timer’s state is shown – in static mode – the settime, while when the timer is started – the remaining time.

IX. SYSTEM PARAMETERSSystem parameters mode is accessed by pressing buttons simultaneously for

more than 5 seconds.In it, on the lower display the parameter’s name is shown. With the desired

parameter is selected, while with [SET], its value is displayed. Changing the values is done with , and selecting the next parameter is done by pressing [SET] again.

Changes in parameters should to be made with extreme caution, due to potentialincorrect function of the device.


X. CONSUMER SETTING OF THE OFFSET OF CHANNEL 1 AND 2

Done only by a service specialist!An incorrect setting can make the device unusable!

In this mode, users can freely enter a programmable value, which will always be added tothe measurement ("offset"). This is used when there's a discrepancy between the valuedisplayed by the device and measured with another reference instrument.

To authorize the user offset of the readings of both channels, it is necessary to power on thedevice while the button is pressed .

In this case, values are added (subtracted when with minus sign) to channel readings. Assigning each separate offset is done the way, as is setting the setpoint SP of each channel

in normal work mode.

Caution – the device does not display previously made changes!Offset mode is available only until the next shut down.

XI. ANTI-INTERFERENCE MEASURES

1. Recommendations for use of connecting wires

- Wires that carry similar type of signals can be packed together, but if the signals aredifferent, the wires must be separated to prevent electromagnetic interaction.

- When there have to be crossed wires with different signal types this must be done at anangle of 90 degrees and a long distance.

- Wires, which carry weak signals and wires connecting the sensors to the controller mustnot be near contactors, motors, generators, radios and wires, which carry large currents.

2. Noise suppression using the built-in in the controller filter

- If the input parameter fluctuates and is not stable it is necessary to reduce the filtercoefficient Fr 1/2. As lower the value, the heavier the filter and slowly change the inputparameter. - If the process variable on the display jumps periodically for short intervals, it is necessaryto increase the parameter tJ 1/2. When increasing this parameter, the device reacts slower atan unexpected “jump’’ in the input, but ignores the short-term interference.


XII. HIDDEN SYSTEM PARAMETERS

Done only by a service specialist!An incorrect setting can make the device unusable!

To access hidden system parameters, it’s needed to feed the power supply while holding and pressing the UP button. In this case, in the list of system parameters, after End, the following ones appear:

Hidden system parameters are “visible’’ only until the next shut down.
