TROUBLESHOOTING

A Fault status is indicated by an amber LED and also by
the 4 to 20 mA output.  Refer to Table 5 for assistance in
correcting malfunctions with the Open Path Eclipse
Detector.

DEVICE REPAIR AND RETURN

The Open Path Eclipse IR Hydrocarbon Gas Detector is
not designed to be repaired in the field.  If a problem
should develop, first carefully check for proper wiring,
programming and calibration.  If it is determined that the
problem is caused by an electronic failure, the device
must be returned to the factory for repair.

Prior to returning devices, contact the nearest local
Detector Electronics office so that a Return Material
Identification (RMI) number can be assigned.  

A written

statement describing the malfunction must
accompany the returned device or component to
assist and expedite finding the root cause of the
failure.

Pack the unit properly.  Always use sufficient packing
material.  Where applicable, use an antistatic bag as
protection from electrostatic discharge.

NOTE

Inadequate packaging that ultimately causes
damage to the returned device during shipment
will result in a service charge to repair the damage
incurred during shipment.

Return all equipment transportation prepaid to the
factory in Minneapolis.

Fault Condition

Corrective Action

Low 24 volts

24 vdc operating voltage is out of range.  Verify proper wiring to the detector and
correct voltage output from the power source.  Power supply faults are self-clearing
when the condition is corrected.  If the fault does not clear, consult the factory.

Dirty Optics

Perform cleaning procedure, then recalibrate as required.  (Refer to “Maintenance” for
details.)

Calibration Fault

If the calibration process is allowed to time-out, the fault is set and can only be reset
with a successful calibration.

Negative Signal Output

This fault is indicated when the signal output drops below 0.5 LFL-M.  Normally
detection capability is not compromised in this condition.  The device was probably
zero calibrated with background gas present.  If the condition persists, purge with
clean air and repeat the zero calibration.

Calibration line active at start-up

The only way to clear this fault is to correct the wiring and reapply power.  Be sure that
the calibration line is not shorted and that the calibration switch is open.  If the fault
does not clear, consult the factory.

EE Error

If power is interrupted while the unit is updating its internal data logs, an EE Error may
occur.  Cycling power will correct this fault.

Other Faults

Consult the factory.
