4.0 Troubleshoot Erroneous Level Alarms
The steps in Section 3.0 should resolve the majority of ELM alarms. There are however some
instances when calibrating an ELM that is at the correct water level will erroneously go into alarm
again.
NOTE:
For all the steps below, press the RS button once to take an immediate measurement. This
will allow testing to confirm any changes have resolved the issue without needing to wait 45
minutes.
4.1 Confirm Sensor Placement
Installation of ELM sensors must be performed by qualified personnel. If a sensor is installed
incorrectly, it can throw false alarms.
When a sensor is mounted using the ELM cradle, it is aligned on the cell using the 2 pointed
arrows on the sides of the cradle.
These arrows line up with the minimum line on the cell. Depending on how the sensor was
mounted, it should alarm when the water level is slightly above or below the minimum line
on the cell. Confirm how the sensors are mounted and that the position is not the cause of
alarm.
There are some mounting positions in which the minimum line on the battery can actually
cause false alarms on the sensor. If the minimum line goes in between the pointed arrows, it
could be the cause of false alarms.
