Figure 5-13. Return Micro-Switch Test
NOTE
It is normal for the back section to move
up if the RETURN button is pushed
when connector CN2 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 CN2 and CN10. Connector
CN10 is located under the slider shroud in the same
area as the hydraulic hoses. Connector CN2 plugs
into the relay box and is the most convenient
location to make circuit continuity checks. See
figure 5-13 for connector pin locations.
a. Switch Test
Turn Main Power ON, lock the table brakes, and
place the table top sections in a level position.
Disconnect connector CN2 from the relay box and
using an ohmmeter, test the wiring and switch
operation at the appropriate pin numbers for the
micro-switch in question as shown in figures 5-14
through 5-18.
NOTE
Be sure to isolate the circuit when mak-
ing continuity checks.
NOTE
If you do not receive the proper continu-
ity results at connector CN2 it does not
necessarily mean the micro-switch is
defective. There could be a problem
with the riser cord between connectors
CN2 and CN10, or in the wiring from the
switch to connector CN10. Further
tests will have to be made to determine
the exact problem.
