Alarm Sounds, Total Hazard Current "Er", and LIM Not Functioning Properly
The LIM has been in operation for some time, but suddenly the Hazard LED is flashing,
the internal audible alarm is on, the red bars of the analog bar graph are flashing, the
Total Hazard Current displays Er, and the LIM is not functioning properly.
Possible Cause: The LIM performs an internal calibration check every 65 minutes.
During this check, it found that an internal component has reached its serviceable
tolerance limit.
Action: Press the Alarm Silence button. The Total Hazard Current displays a number.
Refer to table 4 for an explanation of the displayed number.
