Display of measured values from pin group Analog voltage input 4
If no sensor is connected to the pin group Analog voltage input 4, a measured value for this
pin group of up to 2.2 V will nevertheless be shown on the display and the user interface of
the Cluster Controller.
• In order for a measured value of 0 V to be displayed for the pin group Analog voltage
input 4 when it is not connected, place a jumper wire between pins B5 and B7 in
terminal X8.
Connecting a Sensor to an Analog Current Input
Additionally required material (not included in the scope of delivery):
☐ Up to three sensors
☐ Up to three connection cables (see Section 6.3 "Cable Requirements", page 28)
Requirements:
☐ The sensor must be technically suitable for connection to the analog inputs (see Section 9,
page 78).
☐ The connection cable must be prepared for connection to the multipole plug (see Section 6.5,
page 30).
