Status 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

X
Normal operating
conditions
X X
The actuator is in

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
