7.4 - Diagnostics

Some devices are able to emit signals that serve to recognise their state of
operation or possible faults .

7.4.1 - Signals of control unit

The LEDs of the terminals and the keys on the control unit emit special sig-
nals both to indicate normal operation and possible faults . Tables 12 and 13
describe the cause and solution for each type of signal .
Solution
Check for presence of the power supply; check that the fuses are not
blown; in this case, identify the cause of the fault and then replace
with versions with the same specifications .
This indicates a serious fault; try switching off the control unit for a
few seconds; if the condition persists there is a fault and the
electronic board needs to be replaced .
Normal operation of control unit .
A variation to the status of the inputs SS, STOP, OPEN, CLOSE,
activation of the photocells, or when the radio transmitter is used,
is normal .
This is the same signal of 1 second as on the flashing light
(See table 15) .
Solution
Check the device connected to the STOP input
STOP input active
Solution
S .S . Input not active
Normal if the device connected to the S .S . input is active
Solution
OPEN input not active
Normal if the device connected to the OPEN input is active
Solution
CLOSE input not active
Normal if the device connected to the CLOSE input is active
Solution
- If the parameter "Standard motor rotation direction" is set, the pole
is in the total closing position .
- If the parameter "Inverted motor rotation direction" is set, the pole is
in the total opening position .
- If the parameter "Standard motor rotation direction" is set, the pole
is in a position other than the total closing position .
- If the parameter "Inverted motor rotation direction" is set, the pole is
in a position other than the total opening position .
Solution
- If the parameter "Standard motor rotation direction" is set, the pole
is in the total opening position .
- If the parameter "Inverted motor rotation direction" is set, the pole
is in the total closing position .
- If the parameter "Standard motor rotation direction" is set, the pole
is in a position other than the total opening position .
- If the parameter "Inverted motor rotation direction" is set, the pole is
in a position other than the total closing position .
Solution
If there is no manoeuvre in progress it is normal, otherwise there is a
fault in the encoder or the cable is not connected properly
If there is no manoeuvre in progress it is normal, otherwise there is
a fault in the encoder or the cable is not connected properly
All OK if the manoeuvre is in progress; the flashing is proportional to
the speed .
Note – During the execution of the manoeuvre, the flashing speed
could appear as led on.
