15. Clean the grease filter and filter cartridge and replace them when necessary.
16. Switch on the power to the pumping center. Reset possible low level alarm by pressing the
"Alarm acknowledgement" -button on the control unit.
17. Make a pumping center operation test run by pressing "Extra lubrication" button on the
control unit.
3.3 Manual operation
SAFEGREASE 2 -system can be operated by a manual procedure in the event of an electrical
malfunction. Pressurize the system by using the manual control screws of the pumping center's
solenoid valve group.
If the system is designed with shut-off valves, open the shut-off valve of the channel to be
pressurized before the pressurization of the piping so that the lubricant can be distributed to the
lubrication points after the shut-off valve.
See SAFEGREASE 2 / CLV-2 shut-off valve
.
Caution
Ensure that the pumping center is turned off during manual operation.
One lubrication cycle is performed as follows:
1. Turn the manual control screw of solenoid valve MV1 90° clockwise so that the directional
valve directs pressurization to line 1.
2. Turn the manual control screw of solenoid valve MV3 also 90° clockwise, after which the
pump starts.
3. When the pressure reading in line 1 pressure gauge at the pumping center rises to 200-
250 bar (3000–3600 psi), turn the manual control screw of solenoid valve MV3 to its initial
position (90° counter-clockwise) to stop the pump.
4. Let the pressure act in line 1 for about 2 minutes. Maintain the pressure so that all the
dosers have sufficient time to operate.
5. Turn the manual control screw of solenoid valve MV1 to its initial position (90° counter-
clockwise) to release pressure from line 1.
6. Line 2 can be pressurized after pressure reading has fallen under 50 bar (700 psi) in the
pressure gauge of the line 1 pressure control unit.
7. Turn the manual control screw of solenoid valve MV2 90° clockwise so that the directional
valve directs pressurization to line 2.
8. Turn the manual control screw of solenoid valve MV3 also 90° clockwise, after which the
pump starts.
9. When the pressure reading in line 2 pressure gauge at the pumping center rises to 200-
250 bar (3000–3600 psi), turn the manual control screw of solenoid valve MV3 to its initial
position (90° counter-clockwise) to stop the pump.
10. Let the pressure act in line 2 for about 2 minutes. Maintain the pressure so that all the
dosers have sufficient time to operate.
11. Turn the manual control screw of solenoid valve MV2 to its initial position (90° counter-
clockwise) to release pressure from line 2.
12. Line 1 can be pressurized again after pressure reading has fallen under 50 bar (700 psi) in
the pressure gauge of line 2 pressure control unit
13. Repeat the steps 1–5.
