Problem
No measured values for the con-
nected temperature sensor are shown
on the display.
No measured values for the con-
nected irradiation sensor are shown
on the display.
Though it is not connected, a mea-
sured value of up to 2.2 V for pin
group Analog voltage input 4 is
shown on the display and the user in-
terface.

Cause and corrective measure
The temperature sensor is not correctly connected.
Corrective measures:
• Ensure that the temperature sensor is correctly
connected (see the Cluster Controller installation
manual).
If no measured values are displayed for the irradiation
sensor, either the characteristic curve of the irradiation sen-
sor is not configured or the irradiation sensor is not cor-
rectly connected.
Corrective measures:
• Ensure that the characteristic curve of the irradiation
sensor is configured (see Section 7.1, page 40).
• Ensure that the irradiation sensor is correctly
connected (see the Cluster Controller installation
manual).
If no sensor is connected to the pin group Analog volt-
age 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.
Corrective measures:
• 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.
Cause and corrective measure
The Cluster Controller could not start correctly. A system
error has occurred.
Corrective measures:
• Disconnect the Cluster Controller from the voltage
supply and reconnect it to the voltage supply. Note
that this can lead to loss of system data.
• If the problem persists, contact the Service .
