13.5 Connecting the MCB 114 sensor input module
The MCB 114 is an option offering additional analog inputs for the
CUE.
13.5.1 Configuration of the MCB 114
The MCB 114 is equipped with three analog inputs for these
sensors:
•
One additional sensor 0/4-20 mA.
See section
10.7.13 Sensor 2 (3.16)
.
•
Two Pt100/Pt1000 temperature sensors for measurement of
motor bearing temperature or an alternative temperature, such
as liquid temperature. See sections
10.7.18 Temperature
sensor 1 (3.21)
and
10.7.19 Temperature sensor 2 (3.22)
.
When the MCB 114 has been installed, the CUE will automatically
detect if the sensor is Pt100 or Pt1000 when it is switched on.
