INSTRUCTIONS FOR PUMP USING 85209 CONTROL PANEL
TO PRIME SYSTEM
SUPPLY LINES:
After pump reservoir has been filled with recommended lubricant,
loosen all plugs in dead ends of injector manifolds and supply lines.
Turn vent plug in pump counter-clockwise one complete turn. Depress
manual lube pushbutton on door to start pump. Operate pump until
lubricant bleeds around vent plug to expel air pockets trapped between
the pump and the supply line connection. Tighten vent plug. continue
operating pump unitl lubricant flows around any plug. Tighten plug.
Repeat this procedure until all plug openings are tight and supply lines
are primed. Turn off power to reset controller.
IMPORTANT:
Refer to Owner/Operator Manual C8 259 to program controller on
85209.
FEEDER LINES:
Fill each feed line with lubricant before connecting lines to outlets of
injectors and bearings. This will prevent having to cycle each injector
to fill the feed line between injector and bearing.
INJECTORS:
Checkthe injectors for proper operationby observing the movement
of the indicator stems.
OPERATION:
When model 85530 times out it will initiate a lube cycle. The air
solenoid is energized to deliver air to the pump and air to the vent
valve. Pump begins dispensing lubricant through injectors to the
bearings.
When all bearings have received lubricant, pressure rises in system
to actuate pressure switch. When pressure switch actuates, the
control is reset to de-energize solenoid valve cutting off air to pump
and vent valve. Pump stops, pressure vents and pressure switch
de-actuates. Control begins timing toward next lube event.

TO PRIME SYSTEM
SUPPLY LINES:
After pump reservoir has been filled with recommended lubricant,
loosen all plugs in dead ends of injectors manifolds and supply lines.
Turn vent plug in pump counter-clockwise one complete turn. Set the
delay relay to its maximum position (Refer to Service Manual Section
C8, Page 133 Sefies). Depress push button on top of time control
to start pump. Operate pump until lubricant bleeds around vent
plug to expel air pockets trapped between the pump and the supply
line connection. Tighten vent plug. Continue operating pump until
lubricant flows around any plug. Tighten plug. Repeat this procedure
until all plug openings are tight and supply lines are primed. Open
line switch to shut off pump.
IMPORTANT:
Reset the delay relay to desired interval (Refer to System Planning
Manual).
FEEDER LINES:
Fill each line with lubricant before connecting lines to outlets of
injectors and bearings. This will prevent having to cycle each injector
to fill the feed line between injector and bearing.
INJECTORS:
Check injectors for proper operation by observing the movement of
the indicator stems.
OPERATION
The timer (runs constantly when current is on), drives a cam which
has lobes set for the desired lubrication cycle frequency (Refer to
Service Manual Section C8, Page 133 Series). Lobes engage the
micro-switch lever arm to activate the switch, closing the circuit to
open the 3-way solenoid air valve permitting air to operate the pump.
The pump discharges lubricant through the supply line to the injectors.
After the injectors operate (discharge lubricant to the bearings), pump
continues to build up lubricant pressure in the supply line until sufficient
to operate the pressure control which moves a switch plate, breaking
the circuit to the 3-way, solenoid air valve, shutting off the air to the
pump. Injectors automatically, re-charge with lubricant and system
is ready for the next lubrication cycle.
The pressure controlis factory set for 2,500 psi,adequate for any normal
installation. If higher pressure is necessary (2,900 psi maximum), the
pressure control can be reset;
1) Loosen locknut.
2) Turn the housing clockwise into the pressure control body until
proper pressure is obtained.
3) Tighten locknut.
To lower pressure (1,500 psi minimum);
1) Loose locknut.
2) Turn the housing counter-clockwise into the pressure control
body until proper pressure is obtained.
3) Tighten locknut.
VENT VALVE:
The 83948 Vent Valve is operated by compressed air from the same
source which operates the pump. When pump is in operation, air
pressurekeeps theventvalve closed andlubricantisdirectedthroughthe
outlet and to the injectors. When air to the pump is shut off, vent valve
opens and supply line pressure vents back into the reservoir.
SAFETY UNLOADER:
90942 Safety unloader is provided at the pump outlet to prevent
the build-up of dangerously high lubricant pressure in the system. It
is factory set to open at approximately 3,750 psi to 4,250 psi.
NOTE: Safety unloader requires no adjustment and should not be
tamperedwith.
WHAT TO DO IF:
Pump loses prime: Check lubricant supply.
10127 Vent Plug is provided at the pump outlet for expelling air which
may be pocketed in the lubricant. If pump operated continuously
without discharging lubricant, it is an indication that the pump has lost
its prime. Loosen the vent plug one turn until trapped air is pumped out.
If pumpcontinues to operate withoutdischarginglubricant,10061 Pump
Check and 66002 Steel Ball may be fouled. Remove and clean checks
and check seats. The 83948 VentValve may also be fouled. Foreign
material may prevent 14722 Needle from seating proper]), or 14723
Valve Seat may be worn or damaged. Clean or replace parts.
Failure of injectors to cycle can also be caused by a leak in the supply
line. Examine lines and connections.
Pump fails to operate: Check air supply.
