CONTROL AND INDICATOR FUNCTIONALITY
(Numbers reference the preceding gures)
1. The ball valve Item 47
system. The valve is fully closed when the handle is pointing
valve is fully open when the handle is pointing away from the
control panel.
• Always turn the valve to the fully closed position
before starting and stopping the system.
2. When the compressor system is running, the total hours on
the system is displayed on the hour meter Item 48. This is
and drive belt.
3. The amber fault light Item 49 on the lower right is normally off
when the compressor system is functioning normally. If the
light is illuminated it indicates a system malfunction and the
system will automatically turn itself off by disengaging the
magnetic clutch. The pressure gage should be reading 0 psi
in this condition.
• NOTE: It is acceptable to continue to use the machine
for welding and auxiliary power without
causing any further damage to the compressor
system until it can be serviced.
4. The ON / OFF switch Item 50 controls power to the electro-
mechanical clutch which mechanically couples and decouples
the compressor to the engine. When the switch is pushed to
the ON position, 12 volts DC is applied to the clutch, enabling
the compressor to be driven by the engine. When the switch
is pushed to the OFF position, the 12 volts DC is cut from the
circuit thereby disengaging the clutch and stopping
compressor rotation.
5. The air pressure gage Item 51 indicates that the system is on
The pressure at a tool attached to the system will be lower
depending on the hose length and restrictions (lubricators,
and the tool.
CONTROL SAFEGUARDS TO IMPROVE RELIABILITY
ON/OFF
clutch safeguard
• If the system is on and running and the power switch is pushed
to "OFF" and then back "ON" before the system pressure
reaches 2 psi, the following system behavior will be observed
which is designed to prevent excessive wear or failure of the
clutch:
• The amber fault light will be illuminated.
• The compressor clutch will not be engaged.
• The air pressure gage will show a decrease in pressure until 2
psi is reached.
• When the system reaches 2 psi a pressure switch will then
allow 12V to go to the clutch reactivating the system.
Minimum pressure check valve clutch safeguard.
• A minimum pressure check valve has been installed internal to
the machine just ahead of the ball valve as a safeguard against
starting and stopping the compressor with the ball valve open.
This check valve will help to minimize damage to the clutch
when the ball valve is not closed when starting and stopping
the system over the coarse of the life of the machine. To
ensure long term reliability the ball valve must be closed before
starting and stopping the compressor. For informative
purposes, this check valve has a cracking pressure of 60 psi.
