7.2.7 Troubleshooting
The controller monitors the active and passive signals as follows:
When you leave the commissioning menu, the universal controller checks which
•
sensors are connected.
If, at that time, one of the sensors is connected, but is missing later, a sensor
–
error message is delivered, and the affected sensor is presented on the
display as "Xx ----"
If the cable is short-circuited (passive sensors only), a sensor error message
–
is also delivered, and the affected sensor is presented on the display as "Xx
ooo"
If a sensor is used for the main controlled variable and an error occurs later on
•
during operation, the plant is shut down, that is, the outputs are set to OFF or
0%
If you change an input identifier after configuration of the other blocks is completed,
the controller may deactivate some functions of the other blocks, because they
might otherwise have to operate with units that are invalid for the respective
function block.
