12 TROUBLE SHOOTING AND FAULT DIAGNOSIS

General trouble shooting guide and specific fault code table.

Table 20. Fault code descriptions

Fault code

Description

Condition

Recovery

m10

Over range.

A large concentration has

been detected. The
MIDAS

requires an

independent confirmation

that the gas hazard is

gone.

Supply known clean air to the MIDAS

and clear this fault.

m11

Calibration

expires soon.

The user specified

calibration interval has

elapsed.

Perform zero and span calibrations. Increase span calibration period.

m12

Cartridge expires

soon.

Cartridge is old and will

expire soon.

Replace the cartridge with a new cartridge.

m13

Flow low.

MIDAS

is no longer able

to regulate flow.

Check filters and pump.

m14

Interferent

present.

An interferent is

degrading the ability of
the MIDAS

to detect gas.

Check application.

m15

Temperature near

limit.

Temperature within 2

Celsius of limit.

Check installation environment.

m16

BaseLine fault.

Sensor baseline has

drifted.

Check for background gas concentration, temperature or humidity

fluctuations. Perform zero calibration. Replace cartridge.

m17

Inhibit timeout.

Transmitter has been in

inhibit mode too long.

Resume monitoring or increase timeout value.

F40

Sensor overdosed.

Sensor has been exposed

to high gas concentrations

for long periods.

Replace cartridge.

F41

BaseLine fault.

Sensor baseline has

drifted.

Check for background gas concentration, temperature or humidity

fluctuations. Perform zero calibration. Replace cartridge.

F42

Calibration

expired.

Too long since last

calibration.

Replace or calibrate the cartridge.

F43

Cartridge expired.

Cartridge is too old.

Replace cartridge.

F44

Cell failure.

Cartridge has failed

Reflex™ check.

Replace cartridge.

F45

Stabilization

timeout.

Cartridge has failed to

stabilize.

If temperature or humidity shocks exist, precondition the cartridge. Check for

background gas concentration. Replace cartridge.

F46

Cartridge analog

failure.

Various reasons.

Replace cartridge.

F47

Cartridge

memory invalid.

Checksum error.

Replace cartridge.

F48

Cartridge absent.

No communications.

Reseat cartridge. Replace cartridge.

F49

Cartridge wrong

type.

Cartridge type found to

be incorrect after boot-up.

Replace cartridge.

F80

Temperature limits

Exceeded.

Temperature is outside

limits

Check installation environment.

F81

Flow fail.

Flow < 70% of nominal

for 15 seconds.

Check filters. Check for kinked tubing, Replace pump.

F82

Excessive

electrical noise.

Internal electronics

repeatedly noisy.

Check grounding of MIDAS

chassis. Check termination of cable shields.

Relocate the MIDAS

further from noise sources. Add ferrite inductors to cables.

F83

Pyrolyzer fail.

Pyrolyzer fails to heat.

Check electrical connection to pyrolyzer. Replace heater. Replace pyrolyzer.

F84

Misc. transmitter

fault.

Transmitter is defective.

Service or replace MIDAS
