Connect the pick ups and temperature sensors

Prerequisites:

□

 Pick ups for both volumeters are mounted

□

Temperature sensors for both volumeters are mounted

Aids:

□

KRAL tool set

□

Diagonal cutter

1. Remove the rear device cover.
2. Adapt the cable entry to the cable diameter and cut it to length, see "Connecting cables to the 

tension spring terminals", page 24.

3. Pull the cables of the sensors through the cable entries.
4. Connect the cables for pick ups of Volumeter A in accordance with the wiring diagram on the 

electronic unit, see "Pick up Volumeter A", page 21.

5. Connect the cables for pick ups of Volumeter B in accordance with the wiring diagram on the 

electronic unit, see "Pick up Volumeter B", page 21.

6. Connect the cables for temperature sensor(s) on Volumeter A or Volumeter B.
7. Check the resistance values on the cable for temperature sensor(s) on the side of the electronic unit, 

see Tab. 1, page 25, and see "Notes" in the supplied wiring diagram.

8. Connect the cables for temperature sensor(s) in accordance with the wiring diagram on the 

electronic unit, see "Temperature sensor Volumeter A", page 22, and see "Temperature sensor 
Volumeter B", page 22.

9. Replace the rear device cover.

Tab. 1 Resistance values on temperature sensor(s)

Connecting the analog, relay and pulse outputs

Aids:

□

KRAL tool set

□

Diagonal cutter

CAUTION

Damage to equipment through incorrect connection of temperature inputs (terminals 3–5 and/or 

36–38).

►

Before connecting the electronic unit to the power supply, ensure that all consumers (temperature 
sensors, pick ups) are connected correctly, see wiring diagram.

Check between 

Resistance 

Compensation cables

< 1

Measuring lines Pt100

Depending on temperature: 
100 

Ω

 (0 °C) – 150 

Ω

 (130 °C)

DANGER

Risk of death resulting from electric shock if the connection of hazardous potentials (> 48 V) to the 
potential-free relay outputs (orange terminals 9–11 and/or 42–44) is required.

►

Before wiring these potential-free relay switch contacts, ensure that all wires for this purpose are 
potential-free.
