List of faults
The following listed faults result in a fault message (display in the status line and storage in
the logbook) and are signalized externally if you have configured a corresponding relay with
function 71.
Immediate remedial measures should be taken by qualified maintenance personnel here in
any case. There is a defect in the device. The measurements are not correct.
With function 87, you can switch off each fault individually, which includes suppressing the
display in the status line, storage in the logbook, as well as the external signal.
When a fault occurs, the device leaves the "measure" operating state. After eliminating the
fault, you must leave this new state ("Standby"/"Pause"/"Pause without heating") again via
function 91 in order to put the device back into the "measure" state.
