6.5.3 Replacing the control unit
• Unplug the power adapter from the mains socket.
• Release the catches of the plug cover (on both sides).
• Mark the plug positions to avoid switching them when they are re-connected (see
chapter 6.5.1).
• Unplug all plugs/connecting cables from the control unit.
• Remove the old control unit from its holder.
o To do this, undo the screw and nut.
o Pull the control unit towards the centre of the bed and out of the holder.
• Place the new control unit in position and secure it with the screw and nut.
o Plug all the plug connections back into the corresponding sockets (see chapter
6.5.1).
o Make sure that the O-rings on the plugs are present and undamaged. These seal
the plugs into the control unit.
• When routing the handset cable, ensure that it cannot be damaged by any moving
parts of the bed.
• Put the plug cover back in place. This prevents all the plugs from being pulled out of
the control unit.
• Move the bed completely up or down. This enables the control system to detect the
intermediate stops of the bed.
• Perform an initialisation of the control unit in accordance with chapter 6.5.4.
• To complete the process, check that all the electrical bed adjustments function
properly, in accordance with chapter 6.2!
6.5.4 Initialising the control unit
The initialisation process involves carrying out a reference run, during which the current
positions of the drives are communicated to the control unit. This ensures that the
regulation of parallel running and the adjustment stroke restrictions work accurately.
When is this necessary?
• Before putting the bed into service for the first time
• After replacing the control unit or one or both of the mattress base height adjustment
motors
• If height adjustment of the mattress base is not possible or only possible to a limited
extent
• If height adjustment of the mattress base is not possible or only possible to a limited
extent
- When initialising the control unit, it is important that none of the functions are
locked on the handset!
- Any restrictions on lowering the mattress base height which have been saved
will be lost.
