Low pulse counts from 05-PRS02 |
|
Oil volume and pressure at distributor block 201.18 is OK |
1. |
Pressure Valve not set correctly. |
2. |
Faulty Regulating Valve. |
| 1. | If oil volume and pressure at the block is OK, but you still getting low counts, you can increase the pressure setting on the Pressure Valve. The valve is normally set to 50 bar. |
| 2. | To check the valves current setting, first push the Machine Off pushbutton to turn the lubrication pump off. |
| 3. | Next, place a pressure gauge in the distribution block element that is connected to the Pressure Valve. |
| 4. | Turn the lubrication pump back on and check the pressure gauge reading. The Pressure Valve is initially set up to maintain a pressure between 30 and 50 bar. But if the counts are low, it may be necessary to increase the pressure to get the counter to work properly. |
| 5. | Turn the lubrication pump back on and check the pressure gauge reading. The Pressure Valve is initially set up to maintain a pressure between 30 and 50 bar. But if the counts are low, it may be necessary to increase the pressure to get the counter to work properly. |
| 6. | Turn the lubrication pump back on and check the pressure gauge reading. The Pressure Valve is initially set up to maintain a pressure between 30 and 50 bar. But if the counts are low, it may be necessary to increase the pressure to get the counter to work properly. |
| 7. | Then use a 17mm wrench to remove the connection at the top of the valve. |
| 8. | Then remove the Pressure Valve from the press. |
| 9. | Place the Pressure Valve in vise and then use a 22 mm wrench to remove the gold colored bottom section of the valve. |
| 10. | Insert a 5mm Allen wrench up into the valve body to engage the adjustment screw. Turn the screw clockwise to increase the pressure and counterclockwise to decrease the pressure. Make only very small movements of the screw. |
| 11. | Reassemble the valve, turn on the lubrication pump and check the pressure
gauge to see if the adjustment worked.  Never exceed
50 bar. If 50 bar is reached and the counter still doesn't work, the Pressure
Valve is faulty or there is some other problem. Do not increase the pressure
valve above 50 bar. |
| 12. | Check the lubrication pulses to see if the counter is now working. |
