Belt Alignment and Tensioning
This system is equipped with automatic belt tensioning and does not
require manual adjustment. Always check pulley alignment to ensure
proper belt operation. All components are designed and machined
for precision, some variation in mounting holes may still occur.
Pressure Regulation and Engine Speed Control
The system uses two control systems; an inlet control valve
incorporating a mechanical pressure regulator and an engine speed
control that automatically adjusts engine RPM to respond to air
consumption demand. These control devices provide the following
benefits:
instant response to air flow demands
reduction of standby noise
reduction of cooling system load
fuel conservation when not using air
For information an adjustment, please refer to the section titled
“Adjusting the System”
An external regulator is recommended for operation at pressures
lower than 145 PSI / 999.7 KPA.
Safety Devices
A 200 PSI / 1379 KPA pressure relief valve in the tank to prevent
system over pressure. The system is also equipped with an
automatic rapid blow-down system to discharge system pressure on
shutdown.
There is a switch which only permits operation when the mechanical
or air park brake is applied. Vehicles with automatic transmission are
fitted with a “Drive Disable Circuit”, (DDC) which disables the throttle
control and prevents engine speed increase when the vehicle is in
gear.
The compressor is equipped with an oil temperature sensor which
stops system operation should the temperature become excessive.
