Detcon PI-600 - Manual (Page 36)

1. Verify no target or interfering gases are present.
2. Redo Zero calibration with validated Zero Gas standard.
3. If recovering after a start-up, give more time to stabilize.
Span Calibration Fault
Probable Causes: Failed PID sensor (failed UV lamp bulb, optical window needs cleaning), ice/mud/dust blocking pro-
tective membrane, invalid span calibration gas due to age, type, and contamination or insuff icient f low rate.
1. Verify there is no ice/mud/dust blocking the sensor’sFlame Arrestor.
2. Redo Span Calibration with validated Isobutylene Span Gas standard.
3. Reinitialize unit by plugging in transmitter while holding the magnet on PGM1. Scroll through and select the cor-
rect gas type. Make sure all customer settings are re-entered after “reinitialization”.
4. Clean UV Lamp Filter or replace UV Lamp.
5. Replace with new PID sensor.
Noisy Sensor (continuous drift) or suddenly Spiking
Probable Cause: Unstable power source, Inadequate grounding, Inadequate RFI protection.
1. Verify power Source output and stability.
2. Contact Detcon for assistance in optimizing shielding and grounding.
3. Add RFI Protection accessory available from Detcon.
LCD Difficult to Read
Probable Cause: Needs adjustment.
1. Adjust contrast pot as necessary.
Reporting “ERROR @ XXXXXXX”
Probable Cause: Span calibration calculation error.
1. Reinitialize unit by plugging in transmitter and the swiping the magnet over PGM1 while “Universal Transmitter” is
displayed. Scroll through and select the correct gas type and range (see section 3.12 Universal Transmitter Features).
Make sure all customer specif ic settings are re-entered after “reinitialization”.
