World Class 3000

In operation, when connected to the CRE 3000 Control Room Electronics, line voltage passes through the relay (when on) and is converted into 44 volts by the transformer. If the probe thermocouple indicates that the probe has dropped below operating temperature, a signal from the CRE triggers the triac. The triac then supplies voltage to the probe heater, warming the cell. Conversely, if the probe thermocouple indicates that the probe heater has reached the upper limit of operating temperature, the CRE deactivates the triac, shutting off power to the heater.

NOTE

When using the HPS 3000 with an ex- isting electronics package, such as Models 218, 218A, 225, or TC200, the electronics will not have the in- put/output capacity to support all of the functions mentioned in this sec- tion. Refer to Instruction Bulletin IB- 106-300NE.

B-3 OVERVIEW

B-4 HPS 3000 TROUBLESHOOTING

The HPS 3000 troubleshooting section de- scribes how to identify and isolate faults which may develop in the HPS 3000 assembly.

Install all protective equipment covers and safety ground leads after trouble- shooting. Failure to replace covers and ground leads could result in seri- ous injury or death.

The HPS 3000 troubleshooting may overlap with the probe in use in the system. Faults in either system may cause an error to be dis- played in the electronics package. Figure B-4, Figure B-5,and Figure B-6provide trouble- shooting information.
