While Sullair has built into this compressor a com-
prehensive array of controls and indicators to
assure you that it is operating properly, you will
want to recognize and interpret the reading which

PURPOSE
Pushing in this switch, found adjacent to the controller, cuts all
AC outputs from the latter and de-energizes the starter. A fault
message (E STOP) is displayed by the Supervisor until the but-
ton is pulled out and the "O" pad is depressed.
Depress to turn the compressor ON.
Depress to turn the compressor OFF and reset the common
fault circuit.
To select between continuos (HAND) operation and automatic
stop/start (AUTO) operation. Shuts off compressor automatical-
ly after the compressor runs unloaded for a specified time (rang-
ing from 3-60 minutes [T1]). Restarts compressor when the
pressure switch trips to the reload setting. Dual control is
enabled by pressing the "AUTO" pad.
Records cumulative hours of compressor operation; useful for
planning and logging service schedules.
Continually monitors service line air pressure. It is located on
dry side of receiver downstream from check valve.
Continually monitors receiver/sump pressure at various load
and/or unloaded conditions.
Monitors temperature of the air leaving the compressor unit. For
both air and water-cooled compressors, the normal reading
should be approximately 180ºF to 205ºF (82ºC to 96ºC ).
Indicates when the air filter element change is required. The
gauge shows the red zone when drop through the filter is exces-
sive. The compressor must be running full load for an accurate
indication.
Indicates when a fluid filter element change is required. It shows
red when the pressure drop through the filter is excessive.
Indicates when separator element change is required. Shows
red when the pressure drop through the filter is excessive. The
compressor must be running full load for an accurate indication.
Indicates when the starter is receiving power.
Indicates when compressor is in operation.
will call for service or indicate the beginning of a
malfunction. Before starting your Sullair compres-
