6.8.2 Connecting the MCB 114 sensor input module
MCB 114 is an option offering additional analog inputs for CUE.
6.8.2.1 Configuration of MCB 114
MCB 114 is equipped with three analog inputs for the following
sensors:
•
One additional sensor 0/4-20 mA.
•
Two Pt100/Pt1000 temperature sensors for measurement of
motor bearing temperature or an alternative temperature, such
as liquid temperature.
When MCB 114 is installed, CUE automatically detects if the sensor
is Pt100 or Pt1000 when it is switched on.
6.8.2.2 Wiring diagram, MCB 114
When using Pt100 with a 3-wire cable, the resistance
must not exceed 30 Ω.

6.8.3 Fitting MCB 114 in CUE
6.8.3.1 Enclosures A2, A3 and B3
1. Switch off the power to CUE. See the section regarding mains
and motor connection.
2. Remove the operating panel, the terminal cover and the frame
from CUE. See the figure below.
3. Fit MCB 114 into port B.
4. Connect the signal cables, and fasten the cables with the
enclosed cable strips.
5. Remove the knock-out plate in the extended frame so that MCB
114 fits under the extended frame.
6. Fit the extended frame and the terminal cover.
