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 signals
both to indicate normal operation and possible faults. Tables 12 and 13
describe the cause and solution for each type of signal.

TABLE 12 - Terminal LEDs on control unit
Led Bluebus Cause Solution
Off Fault 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.
On Serious fault 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.
1 flash per second All OK Normal operation of control unit.
2 quick flashesi Input status variation 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.
Series of flashes separated by Various This is the same signal of 1 second as on the flashing light
(See table 15).
Led STOP Cause Solution
Off STOP input activation Check the device connected to the STOP input
On All OK STOP input active
Led PP Cause Solution
Off All OK S.S. Input not active
On S.S. input activation Normal if the device connected to the S.S. input is active
Led OPEN Cause Solution
Off All OK OPEN input not active
On OPEN input activation Normal if the device connected to the OPEN input is active
Led CLOSE Cause Solution
Off All OK CLOSE input not active
On CLOSE input activation Normal if the device connected to the CLOSE input is active
FC1 limit switch LED Cause Solution
Off Limit switch activation - 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.
On Limit switch not activated - 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.
FC2 limit switch LED Cause Solution
Off Limit switch activation - 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.
On Limit switch not activated - 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.
Led encoder Cause Solution
Off The magnet is in front of the sensor 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
On The magnet is not in front of the sensor 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
Flashing light Manoeuvre in progress 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.
