2.5.2. In case of breakdown
The obstacle does
not move
Liquid crystal display is
off
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).
Liquid crystal display is
on
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”).
Check the defects on the
frequency inverter
Refer to AS1320 control board manual.
The obstacle stops
during movement
OP, CL and STOP
commands have no
effect.
Opening and/or closing limit switch is defective or
badly connected.
Note
:
If the trouble persists after you carry out the checks above mentioned, call your local
Automatic
Systems
agent.
