Chapter 7 Error Codes and Troubleshooting

This procedure requires access to the circuitry of a unit

under live power. Accidental contact with line voltage is

possible. Only qualified personnel should perform these proce-

dures. Potentially lethal voltages are present.

Troubleshooting procedures:

1. If an error message is displayed, refer to table 7.1 to see what

caused it and what action to take to correct the problem.

2. Check each point listed below. Experience has proven that

many control problems are caused by a defective instrument

and not the controller

•

Incorrect settings

• Line wires are improperly connected

• No voltage between line terminals

• Incorrect voltage between line terminals

• Connections to terminals are open, missing, or loose

• Thermocouple is open at tip

• Thermocouple lead is broken

• Shorted thermocouple leads

• Short across terminals

• Open or shorted heater circuit

• Open coil in external contactor

• Burned out line fuses

• Burned out relay inside control

• Defective solid-state relays

• Defective line switches

• Burned out contactor

• Defective circuit breakers

3. If the points listed on the above chart have been checked and

the controller still does not function properly, it is recom-

mended that the instrument be returned to the factory for

inspection. Do not attempt to make repairs without a qualified

engineer and proper technical information, as damage may

result. It is also recommended to use adequate packing mate-

rials to prevent damage during transportation.

4. Dismantle the controller according to figure 7.1. Refer to table

7.2 for some probable causes and actions.
