When PID LAMP ERROR is displayed, it is required to carry out the following sensor maintenance
procedure.
(1) Thoroughly review the PID sensor assembly and verify all components are present and installed
correctly.
(2) If assembly is correct then follow the lamp cleaning procedure.
For lamp cleaning instructions, refer to
(3) If the lamp is cleaned and a PID error still exists, replace the lamp.
(4) If the lamp is replaced and a PID error still exists, replace the cell assembly.
If error still exists, device should be sent to an authorized MSA repair center.
Details
This error indicates that
there is an error with the UV
lamp in the PID sensor.
Possible causes include:
-
lamp not installed
-
lamp not installed
correctly
-
damaged lamp
-
non-functioning lamp.
This test is functional at
temperatures ≤ 30 °C
This is a fatal and non-recov-
erable error indicating a
failure in the sensor.
At the completion of the cali-
bration sequence a Fail
message is displayed. On
Galaxy GX2, user can press
the Calibration Details
button to determine which
sensor failed.
Cleaning Procedure
ALTAIR 5X PID
Recommended Action
Complete a calibration. If the device fails cali-
bration, the device should be shut down and
cleaning procedure should be followed
paying careful attention to the orientation of
the lamp.
If user is not in a location where the mainte-
nance procedure can be followed, the PID
sensor can be disabled through the security
menu. This will allow other functioning
sensors to continue working with the PID
disabled.
NOTE: The error may occur when installing a
new PID sensor into the device. This is
expected and the error will be cleared when
the device is calibrated.
Device should be shut down and sent to an
authorized MSA repair center.
If PID sensor failed calibration, device should
be reviewed and then calibration should be
re-run. If PID calibration fails a second time,
device should be shut down and the cleaning
procedure should be followed.
