- LOW TEMP indicator – This blue LED lit solid indicates when the temperature falls to 32 °F (0 °C) for all set-points except the 30 °F (-1.1 °C) set-point. For the 30 °F (-1.1 °C) set-point the LOW TEMP alarm will indicate when the temperature drops to 28 °F (-2.2 °C).
– Blinking indicates sensor fault.
– Blinking fast indicates High Temperature alarm.
- ALARM indicator – This red LED lit solid indicates when there is a high ground fault current.
