NOTE
It is normal for the back section to move
up if the LEVEL button is pushed when
connector CN10 is disconnected from
the relay box.
All of the micro-switches are connected to the relay
box via a wiring harness and the micro-switch riser
cord using connectors CN10, HN10, HN11 and
terminal strips TM1 and TM2. The terminal strips
are located under the hose cover on the top of the
elevation column. Connectors HN10 and HN11
are located under the slider shroud in the same
area as the hydraulic hoses. Connector CN10
plugs into the relay box and is the most convenient
location to make circuit continuity checks. See
figure 5-22 for connector pin locations.
Figure 5-22. Return / Inhibit Micro-Switch Test
5-13. Micro-Switch Troubleshooting
If a problem is suspected in the return / positioning
circuits, disconnect the connector CN10 from the
Relay Box to eliminate the circuits. Ensure that all
table functions operate properly using the Pendant
Control. If the functions do not work properly using
the Pendant Control, refer to the appropriate test
section and make all needed repairs before work-
ing on the return circuits.
