4.3 "Emergency Lowering" (option)
In contrast to the EMERGENCY STOP button, the "Emergency Lowering" option is
intended for when faults occur. A faulty control unit can be bypassed using the
"Emergency Lowering" button. This allows electrical lowering (retraction) of the actu-
ator.
This is only possible for actuators on channel 1.
Pressing "Emergency Lowering"

Press the yellow button (see Fig. 10,

The faulty control unit must then be sent to Magnetic AG, Liestal for repair.
5 Care and maintenance
5.1 Maintenance
The control unit and the battery pack must only be opened and maintained by Mag-
netic Customer Services. Please contact Magnetic AG, Liestal.
Recharge flat batteries as soon as possible. This will increase their service life. When
in storage, batteries should be recharged every 6 months.
The service life of the batteries depends on the load and the charge status. It can last
up to 5 years.
Replacements for damaged or worn-out batteries and faulty charging devices should
be obtained from Magnetic AG, Liestal.
Changing the battery pack
Remove the battery pack by pulling the handle (with sufficient force to counteract the
stop spring). The new battery pack can then be inserted as described in chapter 3.3.
5.2 Functional checks
The following functions should be checked periodically - depending on the frequency
of use:
Mechanical damage
The plastic housing must be checked at least every six months for mechanical damage
(cracks).
Periodically check sealing edges for damage. The sealing rings of the control device
plugs and motor plugs must be checked for damage before each union and exchanged
if necessary.
Power cut-off
Check the power cut-off regularly while extending the actuator to an end position. On
reaching the end position, the control unit must deactivate the actuator without the
button on the control device being released. When the power is cut, a click is heard in
the control unit and the actuator motor stops running.
