Processor and/or Memory Faults

Recycle power in attempt to clear problem

enter all customer settings for range and cal gas level after Restore Factory Defaults.

If problem persists, replace the plug-in transmitter module.

Unreadable Display

If due to excessive sunlight, install a sunshade to reduce glare.

Nothing Displayed – Transmitter not responding

Verify condulet has no accumulated water or abnormal corrosion.

Verify required DC power is applied to correct terminals.

Swap with a known-good transmitter module to determine if transmitter module is faulty.

Faulty 4-20mA Output

If sensor has a normal reading with no faults displayed, and the 4-20 mA signal output is 0mA….

Check that wiring is properly connected at terminal blocks and through to controller inputs.

The 4-20mA output loop must be closed (resistance of < 1000 ohms) to avoid the Loop Fault.

Perform a “Signal Output Check” sequence via Section 3.5.6 and verify 4-20mA output with current meter.

Swap with a known-good transmitter module to determine if the transmitter module’s 4-20mA output circuit is

faulty.
