System Starting and Operation
System Starting
After installing the pump, main line, feed line and
modules, the system is ready to start.
Filling the Main Line
An automatic lubrication system must be free of air in
order to generate enough pressure to discharge grease
from the injectors. The main feed line must be filled with
grease.
1.
Remove a plug or injector from the top of each
manifold assembly. Place a rag below the injector to
capture excess grease.
2.
Start the pump.
3.
Watch for grease to come out of the manifold from
the open outlet port (See Step 1). Allow grease to
flow out of the port for up to one minute to be sure
the grease is free of air and flowing freely.
4.
Stop the pump.
5.
Reinstall injector in outlet port. Torque to 8 ft-lb +/- 2
(10.8 +/- 2.7 N•m).
6.
The system is now ready.
Operation
The following steps describe a typical lubrication cycle.
1.
The pump starts.
2.
The paddle stirs the grease in the reservoir.
3.
The vent valve closes. Pressure builds in the system
to approximately 1900 psi (13.1 MPa, 131 bar)
dispensing grease to all injectors in the system and
providing lubrication to all lubrication points on the
vehicle.
NOTE:
The controller is factory set to seven minutes
ON time. This will provide the pump with ample time
to reach the maximum pressure; approximately
1900 psi (13.1 MPa, 131 bar).
4.
If there is any additional ON time (i.e., time
remaining after building to approximately 1900 psi
(13.1 MPa, 131 bar) the relief valve opens, relieving
pressure in the system back to the reservoir.
5.
After the pump stops pumping grease. The vent
valve opens, allowing grease and pressure in the
fluid lines to flow back into the pump reservoir. The
injectors reset.
6.
The pump rests (OFF time) for 2 hours and 53
minutes.
AUTOMATIC SYSTEM ACTIVATION HAZARD
The system is equipped with an automatic timer that
activates the pump lubrication system when power is
connected or when exiting the programming function.
Unexpected activation of the system could result in
serious injury, including skin injection and
amputation.
Before you install or remove the lubrication system
components from the system, disconnect the battery
and isolate all power supplies and relieve all
pressure.
