SECTION 4.0: DIAGNOSTICS AND COMMISSIONING
4.1 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 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 ONICON if either of the diagnostic lights
indicate a potential problem with the operation of the BTU
measurement system.
4.1.1 Diagnostic Lights
Energy
Located on the end of main unit opposite the cable connection is a red LED labeled BTU.
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.
