Installation and Setup Installation and Setup Pin Assignment Pin Assignment 1 2 3 4 Cable Color brown white blue black Determining Correct Mounting Method Signal current + LED green digital current LED red digital • Remote mounting is recommended if you answer YES to any of the questions below. 1. Is the ambient temperature at the lubrication point higher than +50°C (122°F)? 4 2 NOTE: • Direct mounting should be used for lubrication points that are easily accessible. 2.
Installation and Setup Preparing Lubricator for Installation 5. Install lubricator unit into adapter (B). The lubricator has a self-protection mechanism which shuts off the drive unit at counter pressures higher than 5 bar (72.5 psi). Most bearings require 0.5 - 2 bar (7.2 to 29 psi) pressure (without tubes, extensions, angles, etc.). Use the following procedure to check the counter pressure of the application prior to installation.
Installation and Setup 9. Run the manometer for about 20 seconds. Observe the gauge and repeat this procedure until the pressure registered on the gauge stays constant. 10. To determine the counter pressure, wait approximately 5 minutes until the system has relaxed. Do one more discharge by turning the unit OFF; then ON again until it dispenses for no more than 5 seconds. 11. Wait approximately 5 more minutes to make sure the system does not lose pressure and remains constant.
Installation and Setup Circuit Board Settings Function Display Red and green LED’s (Light Emitting Diodes) are on the circuit board and visible through the transparent cover.

Installation and Setup Selecting Mounting Location Installation Guidelines • For all metal to metal connections (i.e., extensions, reducers, etc.) make sure to use LOCTITE® 243* (semi-tight screw locking). *Loctite® is a registered trademark of the Loctite Corpo• Before installing the lubricator, the lubrication points and any extensions must be adequately pre-lubricated with the same lubricant contained in the lubricator. A 400 gram lubricant cartridge for grease guns is available from Graco.
Installation and Setup Remote Mounting Installations Grease Lubrication with Tube Refer to FIG. 5 - FIG. 7 for examples of correct remote mounting installations. A • Remote installations require a grease line. Graco recommends using a 5/16 inch flexible hose. • Select a position for the lubricator that is easy to access and protected from high-pressure water jets, falling materials, corrosive chemicals and extreme temperatures.

Installation and Setup Installing Lubricator to Lubrication Point 8. Screw lubricator to lubrication point, hand tight only. 1. Clean the lubrication point to remove any potential contaminants. NOTICE To ensure optimal lubrication: 2. Verify the thread of the lubricator corresponds to the thread of the screw point. • 3. Install reducers, extensions, grease line, etc. (if necessary). Seal threads of all connecting parts with a suitable, standard sealant.
Operation Operation Before operation verify: • The lubricator does not have any visible damage. • The lubricator canister is filled with the requested grease or oil. • For oil filled lubrication canisters, an oil throttle must be attached. • • • The “VOL” switches 3 and 4 of the 4-way code switch match the correct size of the lubrication canister. The “TIME” switches 1 and 2 of the 4-way code switch in the drive unit match the desired discharge period.
Changing the Lubrication Canister Changing the Lubrication Canister When the red and green LED light up at the same time, the lubrication canister is empty and should be replaced. NOTICE The drive unit and circuit board must always be protected from moisture to prevent damaging these components. Always change the lubrication canister in a dry place. Removing Lubrication Canister Installing New Lubrication Canister 1.
Changing the Lubrication Canister 8. Plug cable back into lubricator (FIG. 10). FIG. 10 9. The control time will start with the corresponding pause time. Lubrication Canister Disposal Dispose of hazardous fluid in approved containers, and according to applicable guidelines. Read the MSDS to know the specific hazards of the fluids you are using. Storage When lubricators are not immediately installed, they must be stored in a dry, dust free, sunlight protected room, indoors.
Troubleshooting Troubleshooting Malfunction Possible Cause Wrong cable connection Connect cable according to pin assignment (page 6). Check pin assignment. Break in cable Check voltage at plug. Attach new cable. No power supply Check power supply. Make sure there is sufficient power available for the number of lubricators used. Relay defect in machine Change relays.
