Troubleshooting
1. Software does not detect rotator control unit.
Turn the rotator control unit power switch off and back on again. The "Found
new hardware" software installation wizard should detect the unit. During initial
installation, you may also need to restart your computer, depending on the
Windows version.
2. The LED on the rotator controller is flashing red.
This may indicate rotator motor overloading. Open the Diagnostics window
and look for any faults displayed. Inspect the rotator and ensure there is no
physical obstruction to prevent rotator movement, e.g. cables wrapped around
the mast. Check for a short-circuit in the rotator power cable.
3. The LED on the rotator controller is solid red.
The rotator control unit may be overheating. Touch the rotator control unit
enclosure and check if it feels hot. Open the Diagnostics window and look for
any faults displayed. If overheated, switch the system off, let the unit cool
down and try again later. If it works again, try and find the cause. Check power
supply voltage. Check damaged or poor connections in power cables.
4. Rotator is stationary, but should be moving; the LED on the rotator
controller is solid green.
Open the Diagnostics window and look for any faults displayed. Power to the
rotator motor may be disconnected. Check for open circuit in the rotator power
cable. The Reed switch inside rotator may be faulty also.
5. Rotator shaft turns in opposite direction than it should.
The power connections to that motor are reversed. Please correct the crossed
over wires on pins 1 and 2 of the relevant cable.
6. Software performs rotator calibration every time when started.
Ensure that the rotator control unit is switched off by using its power switch
before, before disconnecting the 24 V power to it.
