starting on page 9.
The unit must be securely mounted and grounded
before operation.
Priming the System
1. After the tank (K) is completely filled, remove the
high pressure lubricant supply line (D) from the out-
let.
2. Connect power to the pump (B).
3. Start the pump (B) and run until all of the air has
been expelled and fluid flow is continuous (F
IG
. 18).
4. Reconnect the high pressure lubricant supply line
(D) to the outlet.
Pump Operation Overview
Series Parallel System
1. At the start of the cycle, the lubrication controller (F)
initiates a signal that closes the vent valve (L) and
starts the pump (B).
2. The pump (B) builds pressure in the supply lines (D)
until all the injectors (E) actuate. Then the pressure
switch (T) sends a signal to the lubrication controller
(F) to end the cycle.
3. The lubrication controller (F) terminates the signal
to the pump (B) and power to the vent valve (L).
4. The vent valve (L) opens.
5. Pressure is relieved in the supply lines (D), back into
the tank (K), and resets all of the injectors (E).
Series Progressive System
1. At the start of the cycle, the lubrication controller (F)
initiates a signal to start the pump (B).
2. The pump (B) supplies lubricant and pressure to the
metering devices (AD). When the metering devices
are active, they carry lubricant to the lube points.
3. Continuous lubrication is provided during pump
operation.
4. To control lubrication based upon number of cycles,
a cycle switch can be added to the metering
devices.
Shutdown
For normal shut down, disconnect power to the
lubricator controller (F) and to the pump.
