6.3.5 Setting the analog inputs, terminals 53 and 54
The contacts A53 and A54 are positioned behind the control
panel and used for setting the signal type of the two analog
inputs.
The factory setting of the inputs is voltage signal "U".
If a 0/4-20 mA sensor is connected to terminal 54,
the input must be set to current signal "I".
Note
Switch off the power supply before setting the
A54.
Remove the control panel to set the contact. See fig. 21.

6.3.6 RS-485 GENIbus network connection
One or more CUE units can be connected to a control unit via
GENIbus. See the example in fig. 22.
Fig. 22 Example of an RS-485 GENIbus network
The reference potential, GND, for RS-485 (Y) communication
must be connected to terminal 61.
If more than one CUE unit is connected to a GENIbus network,
the termination contact of the last CUE must be set to "ON"
(termination of the RS-485 port).
The factory setting of the termination contact is "OFF"
(not terminated).
Remove the control panel to set the contact. See fig. 23.

The MCB 114 is an option offering additional analog inputs for the
CUE.
6.5.1 Configuration of the MCB 114
The MCB 114 is equipped with three analog inputs for these
sensors:
•
•
When the MCB 114 has been installed, the CUE will automatically
detect if the sensor is Pt100 or Pt1000 when it is switched on.
