5.1.2 Alarms and operating status indication
LED indication
An LED is present next to cable glands on the controller.
Constant green LED: the supply voltage is connected.
Green LED flashing: Modbus communication is active.
Constant red LED: at least one critical alarm is active.
Flashing red LED: a non-critical alarm is active.
Consultation of alarms and operating status of the extractor by the remote controller ETDZ A
(optional)
The ETDZ A remote control is connected to the Modbus RJ12 "C" connector on the terminal block.
The ETDZ A remote control (touch control) provides accurate information on the type of alarm.
You can view an alarm via ETDZ A, following the instructions below:

Reset alarm via terminal block
After the problem has been solved, you can reset an alarm by closing the contact between DI2 (terminal
7) and GND (terminal 6), an impulse is sufficient (Terminals see "5.1.1 Controller terminal block", page
19).
