2. On a J1 Isolate the Motor that is causing the error by running a Test Dish and making note of
the direction the dish is moving when the error occurs.
3. On a J1 ensure the controller has firmware version 3.9.0 or higher, perform a test dish from the
DATASTORM% prompt to determine the motor that is causing the error.
4. Attempt to move that Motor using manual software motor controls.
5. If the Unit still will not move attempt to move that motor by directly applying power (9-18v) to
the proper wires on the control cable.
6. Continue to troubleshoot below depending on the motor with the issue.
Azimuth and Skew Motors: It is possible to determine if the issue is on the UCU by swapping the
location the motor is plugged into the UCU as the connectors are the same size and has the
same wiring configuration. If the motor causing the error will work while plugged into its counter
parts connection on the UCU then the issue is with the UCU (replace UCU). If it will not, the issue
is with the Motor itself or its count sensor (replace motor).
Elevation Motor: 90% of these will be elevation motor failure 10% could be the UCU. Replace and
test in that order.
7. Contact MotoSAT support for possible parts replacement.
-35 Motor count Azimuth
Issue: The azimuth counter is not counting.
Test man motor movement. Bad sensor, bad UCB, bad scotch lock, broken or shorted wire
Resolutions:
1. On a J1 ensure the controller has firmware version 3.9.0 or higher, perform a test dish from the
DATASTORM% prompt to determine the motor that is causing the error.
2. Attempt to move that Motor using manual software motor controls.
3. If the Unit still will not move attempt to move that motor by directly applying power (9-18v) to
the proper wires on the control cable.
4. Contact MotoSAT support for possible parts replacement.
-36 Bad motor count
Displays in Test Dish Only. Manually man move dish to confirm bad sensor.
Issue: After a dish calibration a count is out of tolerance.
Resolutions:
1. Check the controller's power supply and ensure it is supplying the correct voltage and
amperage for the mount it is controlling.
2. On a J1 Isolate the Motor that is causing the error by running a Test Dish and making note of
the direction the dish is moving when the error occurs.
