FAULTS ON THE PRIMARY (MAINS) POWER SUPPLY
• No power (blackout), or power supply voltage beyond tolerance, due to a fault on the feeder.
The greed LED switches off and the yellow LED flashes quickly. The weather, thermostat and CO2 commands are disabled. To pro -
tect itself against damage due to wind and rain, the control unit allows manual closing for 120 seconds for each of the two zones,
if the battery charge level detected by the control unit is sufficient.
POSSIBLE FAULTS
• Interruption or short-circuit on one or both the motor lines (or protection fuses blown).
• Short-circuit on alarm line from the push button panel (in addition to indicating the fault, the control unit goes into alarm
mode).
• Short-circuit on external alarm line (in addition to indicating the fault, the control unit goes into alarm mode).
• Short-circuit or interruption of the smoke sensors line (in addition to indicating the fault, the control unit goes into alarm
mode).
• Short-circuit or interruption on the EM_CL line.
• Short-circuit on reset line
•
Failure of the board’s self-diagnosis (this test is done automatically at predetermined intervals).
• Anomalous restart and/or without calibration (see par. 7.3).
FAULTS ON THE SECONDARY (BATTERY) POWER SUPPLY
• Batteries disconnected or battery voltage insufficient (batteries discharged and/or degraded).
The yellow LED flashes quickly and the green LED remains lit (if the control unit is in stand-by mode). As long as the primary power
supply is available, the control unit continues to work correctly, but operation in case of a blackout is not guaranteed. If the problem
is due to a low battery charge, the signal must cease within 1-2 hours, otherwise the battery must be replaced as soon as possible.
The charge level on the batteries is checked automatically every 6 minutes.
