Fault messages

Fault messages are issued to the programming unit with plain
text, info no. and a symbol
The display shows:
(e.g. "Fault zone, 207 - motor protection")
Troubleshooting:
1. Check whether the motor protection on the supply/extract
air fan has responded. Do so by measuring across the NC/
COM terminals whether the contact has closed (using an
ohmmeter or continuity tester).
If the contact is closed, the motor protection has responded.
After remedying the fault, press "Acknowledge faults"
on the BML. The system will resume operation.
Press the r.h. rotary selector to change to control level 2.
Turn the r.h. rotary selector clockwise to select the „Fault
acknowledge" menu level and acknowledge by pressing the r.h.
rotary selector again.
The display returns to the default mask immediately after
acknowledgement.
