SMA CLUSTER CONTROLLER User Manual

Problem Cause and corrective measure
No measured values for the con-
nected temperature sensor are shown
on the display.
The temperature sensor is not correctly connected.
Corrective measures:
• Ensure that the temperature sensor is correctly
connected (see the ClusterController installation
manual).
No measured values for the con-
nected irradiation sensor are shown
on the display.
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).
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.
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.
Login
Problem Cause and corrective measure
The login page does not open and the
status LED ( ) is flashing red.
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 .
