ATTENTION
Inform the heating technician whenever any fault messages
are output.
The control device contains substantial error-notification logic.
The error messages appear in continuous alteration with the basic
display. Multiple errors that occur at the same time appear one
after another in the order in which they occurred. The following
types of error message exist:
Sensor measured values that do not lie in the measurement
range are evaluated as an interruption or short-circuit. They
appear depending on the type and allocation with fault code 10 to
20 and index 0 for short-circuit or 1 for interruption.
These error messages evaluate the respective switching status.
They appear depending on the type and allocation with fault code
30 to 40 and index 0, 1 or 2.
These error messages evaluate the control result to be expected.
They appear depending on the type and allocation with fault code
50 to 60 and index 0, 1 or 2.
These error messages refer to address faults such as double
issuance or non-recognition of address settings on the data bus.
They appear with fault code 70 and index 0 or 1, depending on
the type and assignment.
The display and further processing of logical fault messages can
be suppressed through corresponding configuration.
Detected faults are proceed via:
•
Display in the basic display of the controller
•
System fault via display on the information level with the
corresponding information value
•
Inclusion in the fault log (see below for description)
•
If activated, via switching of a fault message output
•
Forwarding via the data bus
