Warning Description

The CCR has determined an issue with the IRMS / Megger card.
If IRMS / Megger functionality was not installed, this warning will only be seen if the IRMS is enabled in the Configuration Menu.
When the CCR determines a warning or setpoint alarm, it will engage the indicator light and the warning will be shown on line 1 of the CCR display.
The CCR will continue to operate in the event of a warning.
Although the CCR will continue operating, warning conditions must still be noted and fixed.
Allowing the CCR to operate in a warning state may cause problems for efficiency, general safety, and longevity of equipment.

Attempt to Correct

Always maintain safe working conditions by using appropriate personal protective equipment (PPE) where necessary.
Turn off power to the CCR.
Once power has discharged and all LEDs are out, ensure the megger card connection screws are tight.
If IRMS / Megger functionality was unintentionally enabled, disable it.
To disable, navigate to Configuration Menu > Monitor Config > Disable > Auto Megger [Disable].
