While a flashing green LED pilot light signalises flap blade motion towards the given position, the
same pilot light reports reaching the required position when shining constantly. If the damper, with
respect to the given time, does not reach the required position, then a red LED pilot light starts to
flash and at the same time, the failure contact is active. Once the damper blade reaches the given
position, this contact is deactivated. The LED pilot light keeps flashing unless the failure is
unblocked by means of the RESET button.

Current failure,
possible cause: • short circuit or interruption of 2-conductor wiring
or damper failure (at BKN..) • Power supply AC 230V missing • defective
thermoelectrical starting • smoke detector activated • exceeded operation time
Failure saved in memory
• Fault in system signalled, system check should be
