State Possible causes Possible solutions
X X
The actuator won’t respond, both
LEDS are off
1)
No power supply
applied
2)
The voltage does not
correspond to the power
supply
of the actuator on the tag
plate
1)
Check
main power supply
2)
Apply the correct
voltage
X
X
The actuator does not complete
the stroke
1)
The actuator was not
correctly commissioned
2)
Stroke programmed
too small (in mode:
“limitation for stroke”)
1)
Repeat commissioning
2)
Check parameters of
valve stroke -> see AMS-
PSCS instructions
X
X
The actuator does not close the
valve correctly
1)
The actuator was not
correctly commissioned
2)
The actuator
force/torque too low
1)
Repeat commissioning
2)
Check actuator
selection
X
X
The actuator is working, but does
not respond to the control signal
variation
1)
The fixed digital signal is
on
2)
The actuator is
configured to work with a
process controller
1)
Check setting of the
control signal -> see AMS-
PSCS instructions
2)
Check the process
sensor
X
X
The position of the actuator
does not correspond to input
values
A non-linear curve was
configured
Check characteristics
configured -> see
AMS-PSCS instructions
Working conditions Possible causes Possible solutions
X
X
Normal operating
conditions
X X
The actuator is in
commissioning mode
Commissioning mode will be
abandoned after
completion
X X The actuator is not commissioned
based on the type of
limitation (opening/closure).
The actuator is
commissioned in automatic
or manual mode
