About this task
The Dock Motor Speed Procedure is required as part of set-up
and calibration. Procedures for opening magnet enclosure covers and
adjusting patient dock hardware (Dock Motor Gear Assembly Adjustments) are provided
in case related Dock problems arise. The Motor On actuation switch
in the dock assembly should be adjusted so it is activated when the
Table Up foot pedal is pressed approximately 3/4 of its total length
of travel. This is factory adjusted; however, it is possible to adjust
the position of the Motor On switch in the field to maintain the proper
actuation level.
Remove dock assembly from dock support by removing capscrews,
lock washers, and clamps (Figure 1).
Figure 1. DOCK ASSEMBLY R/R
Slide dock assembly away from magnet enclosure to gain access
to cable connections.
Remove small trim plate on front enclosure skirt, just above
cutout to access dock motor power cable and Up Limit switch cable
connections (Figure 1).
Disconnect all cables from Dock Assy.
