Servicing the iCon APX Meter Troubleshooting
Installation Check
The most common cause of incorrect data registration is incorrect installation or the installation
of the meter in an application other than its intended application. Other areas to check are as
follows:
• Is the meter installed in a poly-phase, Form 8 or 9 socket (transformer rated models) or a
Form 14, 15, 16, or 17 socket (self contained models)?
• Does the service voltage fall within the voltage range listed on the nameplate?
• Is the T-Bar Seal and/or Demand Reset Seal broken or missing? This indicates possible
tampering; report the incident in accordance with your company’s reporting procedures.
• Is there evidence of mechanical or electrical damage?
• Where fitted, check the phantom load slides to ensure:
▪ The slides are all in the closed position.
▪ The hold-down screws are all securely tightened.
Shop Testing
The meter does not require adjustments outside of the factory. To verify the meter is operating
within factory specifications, verify its calibration using your meter shop’s procedures for testing
poly-phase meters.
Do not permit unauthorized personnel to operate meter-testing equipment or to test meters.
Hazardous voltages are present, exposing personnel to the risk of death or serious injury,
and exposing equipment to the risk of damage. Only authorized, trained personnel may
operate the meter-testing equipment, using approved test procedures and safety precautions.
For information on using an optical pick-up to monitor test pulses, refer to “Test Pulse K
h
Outputs” in Configuration (Chapter 3).
Diagnostic Checks
The meter can run Diagnostic Checks as follows:
• Every 10 seconds (except during a power outage)
• Advanced Diagnostic Alarms depend on the Minimum Service Duration setting and are
monitored constantly
The specific items that are tested are described below. Before the meter indicates a Diagnostic
Check failure, it must fail for one minute (six consecutive tests). Likewise, once a Diagnostic
Check has failed, the meter must pass for one minute for a failure to clear. This process prevents
erroneous failures based on short-term load fluctuations.
