Azimuth Sensor Error
Part A - Testing the Azimuth POT:
1. Ensure the platform is physically in the center position on Azimuth, by disconnecting the
sensor cable and using the manually controls (visually verifying).
2. Remove the plastic Azimuth cover using a Philips screwdriver.
3. Remove the POT and disconnect it from the wiring harness.
4. Rotate the gear CCW until you hit the hard stop. From this point using a volt meter, set it to test
for 2k ohms. Connect the leads to the yellow and green connectors and test the resistance.
Turning the gear CW the value should increase to 2K ohms as your reach the other extreme
(10 full turns).
5. Commencing from this extreme, connect the leads to the yellow and brown connectors and
test the resistance. As you turn the gear the value will increase to 2K ohms as you reach the
other extreme (10 full turns).
6. If you are getting a resistance reading, re-center the POT by turning it 5 turns from either
extreme and carefully reinstall it (For further details please see “Centering the AZ/PL
Potentiometer”). Proceed to PART B.
7. If you are not getting any resistance please contact C-COM Technical Support.
Insert leads into the connectors while rotating the POT gear
IMPORTANT: You must re-center the POT before placing it back into Azimuth Base.
