Fault Possible Causes Remedy
Linear actuator does not
move power loss determine cause and correct
fuse burned out change fuse
linear actuator incorrectly
connected connect the linear actuator
correctly according to the wiring
diagram
short circuit:
- dampness determine exact cause,
- dry linear actuator and check
and correct for leaks
- incorrect connection - correct connection according to
the wiring diagram in the linear
actuator
motor or control is burned out - determine if the mains voltage
conforms with voltage on the
nameplate. Replace motor or
control.
Plug contacts or cable are not or
not correctly plugged in the
socket bar Plug contacts or cable firmly in.
Linear actuator switches
between running left and
running right Motor -operating condenser
defective Replace motor – operating
condenser
Linear actuator does not go
into the end positions and
vibrates Load-dependant limit switches
are maladjusted / defective Remove linear actuator and send
back for repair to the company
Loss of voltage because of too
long connection cables or a too
small cable diameter Install connection cables
according to the required power
Mains deviations outside the
allowed tolerances Ensure "clean" electrical supplies
within the tolerances
Too high plant pressure Reduce plant pressure or employ
appropriate actuating drive
Linear actuator sometimes
fails to work Lead has a loose contact Tighten connections on the
clamping strips
