When reassembling the meter components, be sure to grease all O-rings.
10.29.1 Core processor LED states
Standard core processor LED statesTable 10-13:
LED state Description Recommended actions
1 flash per second (ON 25%, OFF
75%)
Normal operation No action required.
1 flash per second (ON 75%, OFF
25%)
Slug flow (two-phase flow) See Section 10.25.
Solid ON Zero or calibration in progress No action required.
Core processor receiving be-
tween 11.5 and 5 volts
Check power supply to transmitter.
3 rapid flashes, followed by
pause
Sensor not recognized Check wiring between transmitter and sensor.
Improper configuration Check sensor characterization parameters.
Broken pin between sensor and
core processor
The meter requires factory service.
4 flashes per second Fault condition Check alarm status.
OFF Core processor receiving less
than 5 volts
• Verify power supply wiring to core processor.
• If transmitter status LED is lit, transmitter is re-
ceiving power. Check voltage across terminals
1 (VDC+) and 2 (VDC–) in core processor. If
reading is less than 1 VDC, verify power supply
wiring to core processor. Wires may be switch-
ed.
• If transmitter status LED is not lit, transmitter
is not receiving power. Check power supply. If
power supply is operational, internal transmit-
ter, display, or LED failure is possible – the me-
ter may require factory service.
Core processor internal failure The meter requires factory service.
