Latched LOC: The PrimaX Gas Monitor has been exposed to a high gas concentration [above the LEL], and
there is a possibility that the over-range condition may still exist.
The output states are displayed alternating to the measuring value [except for ERROR and
underrange].
10.2 Calibration Errors
Display Cause Troubleshooting
FAIL - 1 Zero not stable
Check zero gas and span gas, see
settings [M-03] and flow rate, repeat
calibration, otherwise replace sensor
FAIL - 2 Zero too low
FAIL - 3 Zero too high
FAIL - 4 Span not stable
FAIL - 5 Span too low
FAIL - 6 Span too high
FAIL - 7 Not enough resolution
FAIL - 8
Catalytic sensor values out of technical
specification
10.3 Error Codes
If an error is detected, the error code E, followed by a numeric code
and a short description, will be displayed.
In this case the normal operation mode of the device will not respond
to gas and the output signal current will be the ERROR value [default
2mA].
Display Cause Troubleshooting
E-01 – E-19,
E-50 – E-53
Latched Hardware/Software Error
E-01 – E-29 latched errors, press
any key for reset device
E-20 – E-29 Sensor Cell error
E-30 – E-39, E-54 Unlatched Hardware/Software Error
E-30 – E-49 non-latched errors,
self-deactivating
E-40 – E-47 Relay error
E-48 Device supply too high
E-49 Device supply too low (< 14.6 V ± 0.2 V)
If an error code is displayed, the normal operation of the device is not possible.
If the error code is still shown after a reset, the device could be defective.
The removal of the hydrogen cyanide and chlorine sensors will not trigger the E-28 sensor error message.
