fault MonitorinG relay (optional)
A fault-monitoring relay (optional) detects all malfunctions or unavailability and communicates this
information remotely.
The relay is normally energised and resets in case of fault.
The detected faults are:
- Power supply failure
- Blown fuse
- Thermal motor protection tripped
- Torque limit switch tripped
6
heater (optional)
For all outdoor installation of an actuator, we recommend to use a heater. To avoid any condensation,
supply the heater as soon as the actuator is on site.

precautions
Replace covers immediately after start-up and make sure that their seals are clean. Never fail
to replace the protection covers. If water ever enters, dry thoroughly before replacing covers.

PROBLEM
CAUSE
CORRECTIVE ACTION
No operation
No LED on.
Motor thermal protective
device tripped
Check if the motor is hot. The actuator will be
available after the motor has cooled down.
Actuator power supply
Check the power supply voltage between termi-
nals L and N. Compare to voltage indicated on the
identification plate.
Blown fuse
Check the fuse and replace if required..
The actuator does not
follow the commands.
The yellow LED is on :
Torque limit switch is
tripped
f the actuator has stopped on a mechanical stop,
disengage it with the handwheel and set again
the stroke (stops and end of travel switches).
Incorrect switches
configuration
Check the switches are set according to the
actuator configuration (M / )
: Check the input signal switches
configuration.
Bad wiring
M: Check commands connection
between terminals 31 - L and between terminals
32 - L.
: Check input signal connection
between the terminals 70 and 71
The actuator does not
stop on the right position
and is hunting.
Dead band setting is not
correct.
See paragraph 3.6
The remote position
feedback signal is wrong.
Bad wiring
Check signal with a voltmeter or a milliammeter
between terminals 71 and 72
Incorrect switches
configuration
Check that switches are set correctly
The torque limiter
indication does not
diisappear once the torque
limiter sensor is no longer
tripped.
Torque limiter data storage The torque limiter data are stored electronically.
To clear a torque limiter memory, a reverse
command must be sent.
The actuator does not
follow the input signal.
Reversed potentiomèter
Check potentiometer connections.
Potentiometer is connected on 16-17-18 positions :
- 4mA (or 0mA or 0V) = Closed position and
clockwise closing.
- 4mA (or 0mA or 0V) = Open position and coun-
ter clockwise closing.
Potentiometer on 18-17-16 positions :
- 4mA (or 0mA or 0V) = Closed position and
counter clockwise closing
- 4mA (or 0mA or 0V) = Open position and
clockwise closing.
Direction of rotation
Check switch 7 setting :
Switch 7 on A : clockwise rotation for closing.
Switch 7 on B : counter clockwise rotation for closing..
