Installation and Operation Manual

ire – Fire Brigade Switch
2.3.4
TURNING-OFF AUTOMATICALLY
2.3.4.1 CAUSED BY POWER GRID FAILURE
If the AC power is switched off, all relay voltages automatically drop and the relays open/interrupt the cir-
cuit.
The PV generator output is switched off. If the AC grid is turned back on, the Q
F
ire system automatically
switches the PV system back into operation.
2.3.4.2 CAUSED BY UNDERVOLTAGE
If there is a cable break within the control lines or if the control voltage drops below 9 VDC (e.g. in the case
of strong fluctuations in the AC network), this is detected as an undervoltage and the system is completely
switched off. The LED ERROR on the Q
Fire
control box lights up red.
Once the error has been resolved, the correct status display and the functioning of the system can be re-
stored by turning the S1 switch off and on again from 0 to 1.
