14.2 Replacing the battery (lead-acid/Li-ion)
The plugs for the components are connected to the appropriate control unit. To prevent
the plugs from being inadvertently disconnected, they are secured with a locking device.
This device can be carefully lifted off using a screwdriver if necessary.
The control unit sockets should be lightly greased inside with Vaseline. The plugs can
then be inserted more easily and the O-rings provide a better seal.
The locking device must always be properly refastened.
For safety reasons, only the complete battery units can be exchanged.
Their housings are fully welded and cannot be opened. When the battery is exchanged,
the type of battery can be changed without any problem - this enables you to change over
to modern lithium ion technology at a later date.
Spare parts can be obtained from Stiegelmeyer.
•
The components (control unit, drives, LCD handset, control box) of the electrical drive
system are maintenance-free and must not be opened. If a malfunction occurs, the rele-
vant component must be replaced in its entirety!
•
When replacing individual components, make sure that the plugs have undamaged O-
rings (for sealing) and are pushed into the control unit as far as they will go. This is the
only way to ensure proper sealing and faultless operation.
•
Ensure the polarity is correct when inserting plugs and do not apply excessive force if the
plug does not fit. The plugs have a groove and therefore only fit into the corresponding
connection sockets with one polarity.
•
Do not wrongly connect the motor connections at the control unit. This can lead to mal-
functions or even result in mechanical damage to the drives due to the system not switch-
ing off at the end position.
•
After replacing the control units and/or the attached drives for adjusting the mattress base
height, always initialise the control unit (= re-align the electronic path measurement for
these drives). This sets a new reference point in the control unit for correctly measuring
the path and avoids faults or damage to the lifting mechanism.
