Status Probable reasons Possible remedy
x x Actuator does not respond, both
LEDs are off
1) No supply voltage applied
2) The applied voltage does
not match the actuator
voltage on the tag plate
1) Check mains supply
2) Apply correct supply
voltage
x x Actuator does not drive the full
stroke
1) Actuator not correctly
commissioned
2) Too small stroke
programmed (in mode “one
position‐dependent cut‐
off”)
1) Repeat commissioning
2) Check valve stroke
parameters ‐> see
instructions AMS‐PSCS
x x Actuator does not close the valve
properly
1) Actuator not correctly
commissioned
2) Actuator closing force/
torque too low
1) Repeat commissioning
2) Check actuator selection
x x Actuator is in normal operating
condition, but does not respond to
set‐value changes
1) Fixed digital set‐value is
activated
2) Actuator is configured to
work with process
controller
1) Check set‐value
parameters ‐> see
instrucions AMS‐PSCS
2) Connect process sensor
x x Actuator position does not
correspond to set‐value input
A non‐linear valve curve has
been parameterised
Verify parameterised
characteristic ‐> see
instructions AMS‐PSCS
Operating conditions Probable reasons Possible remedy
x x Normal operating condition
x x Actuator in commissioning mode Commissioning mode will be
left automatically after
completion
x x Actuator not commissioned Depending on the type of
cut‐offs, the actuator has to
be commissioned either
automatically or manually
Faults within the actuator’s
environment
Probable reasons Possible remedy
x x Too high torque has been
encountered within the valve stroke
1) Actuator not correctly
commissioned to the valve
2) Mechanical block within
the stroke path
3) Improper selection of the
actuator
1) Repeat commissioning
2) Check valve and actuator
for unobstructed running
3) Check actuator selection
x x 1) No proper process feedback (only
in combination with PSIC)
2+3) Maximum control range
exceeds (only in combination with
PSIC)
1) Process feedback wrongly
or not at all connected
2) Process feedback outside
od adjusted range
3) No process sensor signal
available
1) Apply the correct process
feedback signal and check
polarity
2) Ensure the correct process
feedback range
3) Check the process sensor
and its supply voltage
