No position change after receiving
a CLOSE control
No position change after receiving
an OPEN control
Motor thermostat open for high
temperature in the motor windings
Temperature inside the actuator
enclosure higher than 90°C or
lower than -40°C
Value of the actuator position
not valid
Measure of motor speed
not valid
The valve does not move in
presence of an open control
The valve does not move in
presence of a close control
Main voltage lower than -20%
or higher than+20% of the
value stated in the name

The test routine reports a failure
of K1 (coil or auxiliary contact)
The test routine reports a failure
of K2 (coil or auxiliary contact)
The checksum of the EEPROM
memory that contains the
configuration data is wrong
The diagnostic program detects
some malfunction in the electronics
controlling the actuator
The voltage of the lithium battery
is too low (only detected if the
lithium battery is present and the
relevant parameter of the miscellaneous
routine is set to “present”)
The alarm appears only with 3-phase
main supply. The alarm is generated
in case of fault of one of the
phases that supply the actuator
transformer
The analogue 4-20mA signal is not
correct
Operate the actuator in opening
direction. Check the torque
needed to operate the valve.
Operate the actuator in closing
direction. Check the torque
needed to operate the valve.
Check status of actuator
and valve mechanical parts
Check status of actuator
and valve mechanical parts
Wait until the motor
cools down
Ambient temperature too high
or too low.
Verify insulation among
actuator and heat source
Replace position sensor or
re-calibrate both stroke limits
Replace speed sensor
Check status of actuator and
valve mechanical parts.
Recalibrate both stroke limits.
Check status of actuator and
valve mechanical parts.
Recalibrate both stroke limits.
Check main voltage supply
and frequency on terminals
L1, L2, L3. Check that
wires section is correct
Check the contactor
Check the contactor
Re-configure all parameters
(see details next page)
Some circuit is damaged and
does not work
(see details next page)
Change lithium battery
Check main power supply
on terminals L1, L2, L3
Check the external 4-20mA
