1.1 Mounting

The unit must only be located in dry interior locations. Itis not suitable or installation in hazardous locations andshould not be placed close to any electromagnetic elds. Thecontroller must additionally be supplied rom a double-poleswitch with contact gap o at least 3 mm. Please pay atten-tion to separate routing o sensor cables and mains cables.

1. Open the ront cover by pushing it. Unscrew the cross-head screw rom the cover and remove it along with the

ront cover rom the housing.2. Mark the upper astening point on the wall and drill and

asten the enclosed wall plug and screw leaving the headprotruding.

3. Hang the housing rom the upper astening point andmark the lower astening point through the hole in theterminal box (centres 135 mm). Drill and insert the lowerwall plug.

4. Hang the housing rom the upper astening point andattach with the lower screw.

5. Carry out connection in accordance with the terminalallocation.

6. Insert cover and attach with the cross-head screw. Closethe ront cover properly.

ground-common terminal block

The controller is equipped with 13 sensor inputs in total.The ground connection or the sensors has to be carriedout via the ground terminal block (GND). Temperature sensors have to be connected to the

terminals S1 ... S10 and GND (either polarity).

The irradiation sensor (CS10) is to be connectedto the terminals CS10 and GND with correct polarity.Connect the terminal GND o the sensor to the terminalGND o the controller (ground terminal block), and theterminal CS o the sensor to the terminal CS10 o thecontroller.

A owmeter can be connected to the terminals Imp andGND (either polarity).

An external message signal can be connected to the

digital input Din. When the signal contact closes theinput Din, the message !message ext. is generated.This signal is treated like an error, which means that thecontrol lamp fashes red and the message relay is possiblyenergised.

1.2.5 Mains supply

The power supply to the controller must be carried outvia an external power switch (last step!) and the supplyvoltage must be 115 V~ (50 ... 60 Hz). Flexible cables mustbe attached to the housing with the enclosed strain relie and the corresponding screws or be run into the controllerhousing in a cable conduit or trunking.
