Pressing the WARNING button will return the display to the
WARNING screen and the RESET button.
A Warning needs to be reset by the operator by pressing the RESET
button twice.
The possible Warning messages are as follows;
AIREND DISCHARGE TEMP – This will occur if the Airend Discharge
(2ATT) exceeds 97% of the alarm limit, 228_F (109_C) and is not
adjustable.
STOPPED BY ALARM
MODE: MOD/ACS
HIGH DISCHARGE PRESS – This can occur if the machine's loading
function is being controlled by a host device such as a sequencer or an
ISC. This warning will occur when the package discharge pressure is
above the maximum offline pressure (rated pressure plus 3 psig (0,2
bar)) for more than 3 seconds. This warning will cause the compressor
to unload. The host device will not be able to load the compressor until
the package discharge pressure falls to the rated pressure of the
machine.
SENSOR FAILURE 4ATT – This will occur if the Package Discharge
Temperature Sensor (4ATT) is missing or broken.
STOPPED BY ALARM
MODE: MOD/ACS
