3 Description of Function

3.1 Purpose of the Device

The 979429.02 Temperature Controller is a high-precision tool for either simple ON/OFF two-position

control and three-position control (difference temperature between two temperature values) or

optionally with performance approximation via P.I.D. operating mode.

With freely programmable hysteresis in ON/OFF mode.

The model type 979429.02 was designed for heating and cooling operation in a control range between

-199 … 2.300°C. The measuring range is determined by the employed sensor type.

Simple operation and parameterization as well as useful additional functions such as recognition of sensor

damage with automatic power cut-off, alarm output, 3 completely free configurable switching outlets etc. offer

the necessary flexibility for industrial use. Due to the freely programmable hysteresis overlaps with rising or

falling edges, additional possibilities for use as temperature limiter or as unilateral edge-controlled switching

conditions arise for two-position or three-position operation.

4.3 Interfaces

General Information:

Model 979429.02 is intended for resistance sensors Pt100; furthermore for thermo elements of type T, R, J,

B, S, K, E and Wre-Wre25. For use with platinum sensors (PT100) the degree display is within 1/10 degree

of accuracy. For use with thermo elements the measuring display has an accuracy of the measuring

temperatures in the four-digit range (max. 2300 degrees).

The 979429.02 possesses a reduction switch necessary for the connection of PT100 sensors in three wire

connection for compensating the cable resistance. Cable lengths of up to 50 meters measuring lead can be

realized without intermediate transmitter (min. 3x0.22mm²).

Inlets:

Control Voltage:

The supply voltage for the controller is 230V AC 50Hz (see also connection diagram).

4.4 Wiring Diagram

Warning

Working with electricity can be very dangerous! Imitating the illustrated examples can

cause accidents and must be performed by qualified experts only!

Check whether the voltage information on the control corresponds with these

instructions!

(No warranty with wrong connection!)

Hysteresis:

Temperature value or time value necessary only in the ON/OFF operating mode, which

passes by between the automatic switch-off when the set value is reached and the

automatic restart. This value can basically be indicated in degrees C or as time value. The

hysteresis is necessary in order to avoid the so-called “flickering” of the relay, when the

temperature value reaches the set value.

After selecting confirm your menu settings by pushing SET

You will then automatically return to the menu selection or to the control mode.

Note: in cooling operations (menu “rd”=1), AH1(2) is the turn-on value and AL1(2) is the turn-off value after turning on!

IMPORTANT

The color coding of the sensors is not standardized. Polarity with clamps 6, 7, 8 causes a

fault message or an unrealistic display value. This will not damage the controller. If the

sensors are exchanged, the correctly installed sensor can be calibrated during operation at

a random reference temperature (see page 5, menu PSb).

Make sure the sensor is suitable for the temperature range to be measured. PT 100

sensors with lower or higher measuring ranges can be connected to the device.

Push the "SET" button followed by code entry 0001 in order to gain access to these

parameters.

Use the below table for the setting of temperature values after you have entered the basic

settings according to the parameter table „Basic Settings“, page 13 correctly.
