8.0 Troubleshooting

8.1 General Troubleshooting Procedures

Many problems can be isolated with the following general techniques:

• To verify power to the unit, recheck +28 VDC power is applied to the

proper pins on the unit. Use a voltmeter to verify correct level.

• Reset by removing power from the unit for at least one minute and

reapply power. Verify the problem still exists.

• Recheck all connections to the unit for security. Check all harness

runs for possible pinching. Recheck all pinouts for application

accuracy.

• To check data bus integrity, utilizing a voltmeter, oscilloscope, or other

voltage instrument, verify proper input voltage on the data bus pins.

• The RS-485 data bus is a bi-directional bus that does not have a ‘bus

controller’. The bus uses a differential digital signal that will transmit

only when commands are entered via switch selection or other system

synchronizing commands. The “A” leg of the bus is HI and the “B” leg

LOW.
