5-7. Return-to-Level Micro-Switches.
The return-to-level feature is activated by a single
button on the pendant control and automatically
levels the major table functions, lateral tilt, tren-
delenburg, back section, and leg section.
The return-to-level system consists of 6 micro-
switches, 2 electrical connectors, and the related
wiring. The micro-switches are mounted on or
adjacent to the function they control and are wired
for normally open or normally closed operation.
The micro-switches are lever actuated and can be
adjusted at the individual switch mounting brack-
ets. See figure 5-12.
The micro-switches operate on low voltage, and
control the function circuits (pump/motor and ap-
propriate solenoid valves) when activated by the
pendant control RETURN button.
The micro-switches are wired to the relay box
through a riser cord and to the 15 pin connector
CN2. See figure 5-12 for switch location and
identification.
5-8. Troubleshooting
If a problem is suspected in the return circuits,
disconnect the connector CN2 from the Relay Box
to eliminate the circuits. Ensure that all table
functions operate properly using the Pendant Con-
trol. If the functions do not work properly using the
Pendant Control, refer to the appropriate test sec-
tion and make all needed repairs before working on
the return circuits.
