Compressor High Discharge Trip Alarm
The high discharge trip is generated when a high discharge pressure condition is present and compressor proof fails. When
a high discharge trip alarm is generated,
“ ALARM ” will be displayed next to “ COMP High Dis Trip ” on the Alarms screen.
When the discharge pressure decreases, and the compressor proof is made, the compressor high discharge trip will
automatically reset.
