MEMOLUB HPS SERIES SUPPORT & KNOWLEDGE BASE

You can test and/or check whether MEMOLUB HPS is working correctly at anytime by unscrewing MEMOLUB from the MEMO by one turn and screwing it back. MEMOLUB HPS will expulse once after being mounted to the MEMO.

If the environment is too noisy, unscrew MEMOLUB from its MEMO and, push on one of the three switches at the bottom of the housing for a few seconds. MEMOLUB will then make an expulsion to confirm that electronic, mechanical and batteries are ok.

Operate this operation three times pushing each switch at least once to ensure all three switches are operational and the complete gavage of the pump with the adequate lubricant. This operation has to be done with a cartridge inside the MEMOLUB HPS.

Make a manual test of MEMOLUB HPS by using a MEMO with the three rings in the ring-holder.

If MEMOLUB HPS does not work, check the following:

• Is there a battery pack in the MEMOLUB and is it correctly inserted?
• Are the batteries ok? Use another battery pack to double-check.
• Are there one or more plastic rings inside the ring-holder? If not, no switch will be activated and MEMOLUB HPS will not work. Make sure you insert them correctly as explained in the installation guidelines.

If MEMOLUB HPS does function, but no grease comes out of the automatic lubricator check the following:

• Is there a lubricant cartridge inside the MEMOLUB HPS? If not, recharge the unit with a cartridge as described in the installation guidelines.
• Was the spring mounted correctly inside the transparent housing? If not, please mount it again as described in the installation guidelines.
• Is the pump of the MEMOLUB HPS primed? If the cartridge of MEMOLUB HPS was totally emptied before replacement, some air could have been sucked into the system and the pump would cavitate for a certain number of cycles. Place a grease handgun on the suction valve of the red housing and pump grease through the unit as explained in the installation guidelines.

If MEMOLUB HPS does function but the lubricant cartridge does not empty or not in the predicted timing there might be that of the following issues occurs:

• The piping is clogged: use a handgun to clear the pipes.
• One of the outlets of the distributor block has been voluntarily obstructed. Use bridging elements to reduce the number of outlets of a distributor block.
• The piping is damaged. Replace the piping.
• Counter pressure at the MEMOLUB HPS outlet is higher than 20 bar: please respect the tubbing diameters, tubing lengths, the number of outlets per distribution block and the working temperatures. Also, use fittings with openings larger than 4mm (0.157").
• At working temperature, the base oil viscosity of the grease is higher than 10.000cSt. Please use low temperature lubricants.

MEMOLUB HPS does function and empties correctly, however no lubricant is reaching the lubrication point. Possible causes are:

• The piping might be damaged, please check and replace if necessary.
• A fitting is not correctly screwed or sealing is missing, please check and replace or add if necessary.

MEMOLUB does not require any specific maintenance. When used in humid or dusty atmospheres MEMOLUB HPS can be cleaned with compressed air or a slightly humid rag. To clean MEMOLUB HPS do not use solvents or plunge unit in any liquid. It is also possible to equip your MEMOLUB HPS with a protection cover. For additional information, please contact your local MEMOLUB dealer.
