4.8 DIAGNOSTICS

The ONICON System-30 BTU MEASUREMENT

SYSTEM uses a microprocessor to calculate

energy. Factory programmed settings provide

energy total outputs in accordance with the

customer’s application data. An optional

isolated analog output for energy rate, ow rate

or delta T may also be available. Refer to the

Btu meter calibration sheet for a complete listing

of factory settings. These settings cannot be

changed in the eld. Contact ONICON factory

service personnel if changes to the calibration

are required.

The System-30 is equipped with diagnostic

indicator lights that conrm the operation of

the microprocessor and its input circuitry.

Please contact the ONICON factory service personnel if either of the diagnostic lights

indicate a potential problem with the operation of the BTU MEASUREMENT SYSTEM.
