Faults within the actuator's
environment
x
Actuator drives into a preset
position
x Set‐value disconnected or outside
the parameterized range
Stored end position could not be
reached
x
Stored end position has been
passed over
x
Actuator supply voltage too low
Faults within the actuator
Actuator has reached lifetime limit
x
Faulty electronics or invalid
parameters
x
Critical or maximum temperature
reached
x Mechanical fault in the actuator
TRACING FAULTS CHARTS (A/B ONLY)
Probable reasons
1) Signal is applied to the
binary fail‐safe input
2) Supply voltage failure on
actuators with optional
PSCP
1) Set‐value not connected
2) Wrong polarity of set‐
value
3) set‐value signal outside
parameter range, please
check
Loose or dirty valve seat
Valve seat worn or defective Check the valve seat
1) Improper wiring of the
mains supply
2) Jitter in supply voltage
3) Too low supply voltage
from PSEP (with optional
PSEP)
Probable reasons
Wear and/ or running time Contact PS service team
1) Supply voltage
interrupted during
commissioning
2) Defective electronic
component
1) Too high numbers of
starts
2) Ambient temperature too
high
Defective mechanical part
Possible remedy
1) Disconnect the signal
2) Check supply voltage
1) Apply set‐value
2) Check the set‐value
polarity
3) Check the set‐value range
Check the valve seat
1) Check mains wiring
2) Check supply voltage ‐>
see datasheet
3) Contact PS service team
Possible remedy
1) Reload parameters (‐> see
manual AMS‐PSCS), then
repeat commissioning
2) Contact PS service team
1) Check application and its
adjustment
2) Check ambient
temperature and try to
reduce it ‐> see relevant data
