Operation

Pressure Relief Procedure

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, in- cluding fluid injection or splashing in the eyes or on the skin, always follow the

Pressure Relief Procedure whenever you

DAre instructed to relieve the pressure

DShut off the pump

DCheck, clean, or service any of the system equipment

DInstall or clean the dispensing devices

1.Disable hydraulic supply to pump (Fig. 2, item D) by isolating it it from the high pressure hydraulic supply using ball valve (AA).

2.Do one of the following:

DOpen the pressure reducing valve to reduce trapped hydraulic pressure,

or

DCycle the timer to open the 3–way solenoid valve to reduce trapped hydraulic pressure.

Note: Gage on control module should read zero pressure after performing this step.

3. Disconnect power from Lubrication Controller (J).

WARNING

MOVING PARTS HAZARD

Do not insert finger into the overflow port while filling a reservoir equipped with a

follower plate. Injury or amputation could

result.

Start-up

Prime Vent Line. The first time the reservoir is filled, use the vent valve outlet. This removes all air from the vent line (Fig. 2, item V).

1.Connect lubricant supply hose from remote filling station pump unit to outlet of vent valve (U).

2.Remove plug in fill port (K) located at bottom of reservoir.

3.Slowly turn on supply lubricant until lubricant appears in fill port.

4.Remove lubricant supply hose from vent valve.

Fill Reservoir

1.Connect lubricant supply hose from remote filling station pump to fill port (Fig. 2, item K).

2.Connect automatic lube system main supply line (G) to vent valve (U) outlet.

3.Remove plug from overflow port (L).

4.Slowly turn on supply lubricant until level of lubri- cant reaches overflow port.

Note: For systems with a follower plate, fill until the follower plate reaches the overflow port.

Note: Refer to Automatic Lube System Design Guide- lines Manual 309015 for instructions on priming re- maining system lubricant lines and further operating instructions.

WARNING

COMPONENT RUPTURE HAZARD The maximum working pressure of each

component in the system may not be the same. To reduce the risk of

overpressurizing any component in the system, be sure you know the maximum working pressure of each component. Never exceed the maximum working pressure of the lowest rated component in the system. Overpressurizing any component can result in rupture, fire, explosion, property damage, and serious injury.

Regulate hydraulic pressure to the pump so that no fluid line, component, or accessory is overpressurized.

5.Set hydraulic pressure to pump at lowest pressure

needed [between 600 psi (41 bar, 4.1 MPa) and 1200 psi 83 bar, 8 MPa)] to get desired output results [between 2500 psi (172 bar, 17 MPa) and 3500 psi (241 bar, 24 MPa)].

6.Set hydraulic flow rate to pump at lowest flow rate needed to get desired results.

7.Read and follow instructions supplied with each system component.

Note: With a primed pump and sufficient hydraulic supply, the pump starts when the timer activates the solenoid valve. The pump stops when the timer deacti- vates the solenoid valve.
