4.7 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, flow 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 field. Contact ONICON factory
service personnel if changes to the calibration
are required.
The System-30 is equipped with diagnostic
indicator lights that confirm 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.

This LED will flash as energy is transferred.
Liquid Flow
Located on the end of main unit opposite the cable connection is a red LED labeled FLOW.
This LED will flash at a rate that is proportional to the liquid flow rate. An unlit LED
indicates no flow signal.
