OPERATION
PURPOSE
The engine switch is used to both energize the compressor's electrical
system and engage the engine/starter. It also has a built-in anti-restart
device that protects the starter from engaging while the engine is
running. The switch must be turned back to the "off" position before the
engine can be re-started.
Monitors the condition of the batteries and the charging circuit. The
normal reading is 24 to 48 volts.
Continually monitors the pressure inside the receiver tank at various
load and unload conditions.
Monitors the temperature of the engine water. The normal operating
temperature should read approximately 160ºF to 210ºF (71ºC to 99ºC).
Depicts system related diagnostics. Can be used for system
performance monitoring.
Monitors the temperature of the air/fluid mixture leaving the compressor
unit. The normal reading should be approximately 210ºF to 250ºF
(99ºC to 121ºC).
Prevents starter engagement when the air system is pressurized.
Monitors the fluid level in the receiver tank. Proper level is always
visible in the sight glass. Check the level when the compressor is
shutdown.
Opens the electrical circuit to shut down the compressor when then
receiver tank temperature reaches 250ºF (121ºC).
for service or indicate the beginning of a malfunction.
Before starting your Sullair compressor, read this
section thoroughly and familiarize yourself with the
controls and indicators—their purpose, location and
use
.
NOTE
When restarting the compressor, the controller will
not allow restart until system pressure falls below
10 psig (0.7 bar) or less. More than 10 psig (0.7
bar) can put extra load on the starter.
