4.5 Replace ELM Sensor
If all of the above fails to fix the issue, the ELM sensor itself could be the issue. Replacement of the
sensor may resolve erroneous alarms.
1. Remove the cover from the ELM.
2. Disconnect the ribbon cable.
3. Pull the sensor out of the cradle by slightly pushing out on the cradle clips.
4. Insert the new sensor and plug the cable in.
5. The sensor should power on.
6. Calibrate the sensor following the steps in section 3.0.
5.0 ELM Temperature Alarms
The ELM sensor also alarms for over temperature on each cell. On the Vigilant web-interface this is
referred to as "ELM Case Temperature". It does not report an actual value, rather it alarms against
a set value on the sensor. Below are the settings available:
95°F (35°C)
- Default setting from factory
120°F (49°C)
145°F (63°C)
Temperature alarm off
If ELM sensors are in temperature alarm constantly, the limit may need to be changed or disabled
entirely. If the temperature alarms are not an issue, it's recommended to leave the setting at
default as the Vigilant records actual temperature values per each cell.
5.1 How to Check Temperature Setting
Note:
All actions to change the temperature setting, including saving the changes, must be carried
out within 30 seconds, after which the sensor will revert to normal operating mode.
1. Press and hold the RS button for two seconds until all the LEDs turn on
