Synchronizing The Lateral Tilt Function - Mizuhosi 5803 Manuel Du Propriétaire

4.4 Synchronizing The Lateral Tilt Function

Normally, the head end crossbar and tilt drive mechanism are synchronized so that the
tilt drive is in the middle of its travel range when the crossbar is level. It is possible for
the crossbar and tilt drive to become unsynchronized if the crossbar is rotated manually.
Also, the head end crossbar and foot end crossbar can become unsynchronized (not at
the same tilt angle) if a crossbar is rotated manually or the 5803 Advanced Control Base
is operated without a table top in place. The crossbars must be synchronized to each
other, as well as to the tilt drive mechanism.
Never attempt to attach a Table Top to the 5803 Advanced Control Base if the
head and foot end crossbars are not horizontal and level. Doing so may cause
damage to the table top or the tilt drive system.
To verify synchronization of the tilt drive and head end crossbar:
1. Confirm that the 180° rotation lock is engaged and Indicator light / switch illuminated.
2. Confirm that the rotation safety lock is engaged and Indicator light / switch
illuminated.
3. Use the hand pendant lateral roll buttons to rotate the head end crossbar until it is
level.
4. Confirm the tilt drive status indicator light illuminates (on hand pendant or head end
pivot assembly) indicating proper synchronization.
 If the light will not illuminate, the head end crossbar and tilt drive are not
synchronized.
 If the head end crossbar will not level using the hand pendant lateral roll buttons,
then the head end crossbar and tilt drive are not synchronized.
To re-synchronize the tilt drive and head end crossbar:
Different techniques are used depending on whether a table top is attached to the base
or not. Choose from the following cases.
Case 1: Table top is coupled to the base
1. Confirm table top is attached to H-frame and securely locked in place with the T- pin.
No patient or load should be on table top.
2. Turn power switch on.
3. Turn off the rotation safety lock. The switch should not be illuminated.
4. Rotate the 180° rotation lock lever counter-clockwise until it is disengaged. Be
careful – this allows the table top to swing freely.
5. The tilt drive mechanism will automatically return to the middle of its range. While
this occurs, you will hear the tilt motor running, but the table top will only rotate a
little (if at all).
6. When the tilt motor stops, observe the tilt drive status light. If it is illuminated, then
the drive is in the middle of its travel range.
7. Verify that the head end and foot end crossbars are level.
8. Turn on the rotation safety lock. The indicator light should illuminate.
