
Check the general power supply.

Check the voltage on the circuit breaker (4:1),
and check if this late is on.

Check the connection of the control wires
referring to the electrical diagram, as well as
their tightening.

Check the state of the fuses (5:1, p10) on the
electrical control board.

Check that the green LEDs are lit on the logic
control board (5:6, p10).
- If not, check the general fuses (5:1, p10).
- If so, check that the logic board is not in
programming mode (cable RJ45, plugged in
socket 5:5, p10).

Check that the red LEDs (other than the
analogue output ones) on the logic control
board are on (5:6, p10).
- If not, cut the supply voltage and remove the
control terminal blocks (5:6, p10) (on the
AS1320 and AS1321, if present). Turn the
power back on and then check whether the
red LEDs are on. If that is the case, there is
a short circuit in one of the control terminal
blocks (5:6, p10). In order to reactivate the
outputs, the logic board has to be turned on
again.
- If so, refer to the displayed breakdowns
("PRDSTD – BL_xxx" menu  "Log"/"Close
Status"/"Open Status").
Refer to AS1320 control board manual.
Opening and/or closing limit switch is defective or
badly connected.
