CONTINUOUS MODE
(for oils only)
This "fast" mode should be reserved for oils only (see electrical specifications below). In the case of a grease, the timespan between two strokes may be too short to suck it out from the cartridge. We then recommend using the intermittent mode (see above).

FAQ
-
How can I test and/or check if MEMOLUB PLCD is functioning?
You can test and/or check whether MEMOLUB PLCD is working correctly at anytime by powering it OFF and ON again from the PLC. MEMOLUB PLCD will then expulse once.
This operation has to be done with a cartridge inside the MEMOLUB PLCD.
-
What to do if my MEMOLUB® PLCD automatic lubricator is not functioning?
Make a manual test of MEMOLUB PLCD by using a MEMO with the three rings in the ring-holder.
If MEMOLUB PLCD does not work, check the following:- Is the power supply ON?
- Does the power supply have the right ampliture (24V AC/DC) ?
- Is there any discontinuity in the wiring?
- Are there two brass rings inside the ring-holder? If not, no current can feed MEMOLUB PLCD and this latter will not work. Make sure you insert them correctly as explained in the installation guidelines.
-
What to do when there is no lubricant coming out of my MEMOLUB PLCD?
If MEMOLUB® PLCD does function, but no grease comes out of the automatic lubricator check the following:
- Is there a lubricant cartridge inside the MEMOLUB PLCD? 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 PLCD primed? If the cartridge of MEMOLUB PLCD 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.
-
What to do when the lubricant cartridge is not emptied correctly?
If MEMOLUB PLCD 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 PLCD outlet is higher than 13 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.
-
What to do when the lubricant does not reach the lubrication point?
MEMOLUB PLCD 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.
-
Does MEMOLUB® PLCD needs specific maintenance?
MEMOLUB does not require any specific maintenance. When used in humid or dusty atmospheres MEMOLUB PLCD can be cleaned with compressed air or a slightly humid rag. To clean MEMOLUB PLCD do not use solvents or plunge unit in any liquid. It is also possible to equip your MEMOLUB PLCD with a protection cover. For additional information, please contact your local MEMOLUB dealer.
