MULTILUBE – SYSTEM TROUBLESHOOTING
1 SYSTEM TROUBLESHOOTING
1.1 Control unit does not operate
1.1.1 User interface does not operate
Operation disturbance Cause of operation disturbance Solution
Display and LED signals of user
interface are not lit. No supply voltage on pumping unit. Check supply voltage.
1.1.2 Control center does not operate
Operation disturbance Cause of operation disturbance Solution
Green LED-signal of control
center is not lit. Main switch of the control center is in OFF-position.
The fuse has blown.
The LED-signal has blown.
Turn the main switch to ON-
position.
Replace the fuse.
Replace the LED-signal.
1.2 Control unit triggers an alarm
1.2.1 User interface triggers an alarm
Operation disturbance Cause of operation disturbance Solution
The red P LED-signal of user
interface is blinking. Lubricant reservoir is empty. Fill the lubricant reservoir.
Reset the alarm.
The red LED-signal for line is
blinking at the user interface.
Alarm, low pressure on display.
The pressure shown at pressure
control unit is below the set
pressure high limit value.
The lubricant has stiffened in the
piping because of the operating
conditions (e.g. cold, heat).
Header piping leaks.
There is air in the pumping unit.
There is air in the header piping.
Set the maximum pressurization
time longer or change the lubricant
for an appropriate lubricant.
Locate and repair the leakage.
Remove air from the pumping unit:
1. Disconnect header piping
connectors.
2. Start pumping unit
3. Open pumping element
deaerating screw.
4. Pump until only lubricant (no
air) is coming out of the
deaerating screw.
5. Tighten the deaerating screw.
6. Connect header piping
connectors.
Remove air from the header and
branch piping.
Reset the alarm.

1.3 A lubrication point gets too little lubricant or nothing at all
Operation disturbance Cause of operation disturbance Solution
The rotation of the bearing makes
noise, is trembling or the
temperature is rising.
The dosage adjustment of the
doser is too small. Increase the dosage.
Doser does not operate The lubrication point has clogged.
Lubrication pipe or hose has
clogged.
The doser is damaged.
Clean the lubrication point.
Clean or replace lubrication pipe
or hose.
Replace the doser.
Grease leakage in the area of
lubrication piping. Lubrication piping between the doser and lubrication point is
damaged.
Check and repair the lubrication
piping.
1.4 A lubrication point gets too much lubricant
Operation disturbance Cause of operation disturbance Solution
Considerable grease leakage in
the lubrication point.
The temperature of the bearing
rises.
The dosage adjustment of the
doser is too large.
The doser is damaged.
Adjust the dosage to a smaller
amount.
Replace the doser.
2 WARNINGS
Caution The lubrication disturbances of the critical lubrication points must be repaired
immediately, since inadequate lubrication rapidly damages the equipment or
machinery being lubricated.
Note In the event that the operation disturbance can not be repaired with the help of
these instructions, please contact the supplier immediately.
