The following is a description of a low output power indication on your Enercon Compak 2000 power supply.
| Symptom & Fault |
| Symptom |
The output power from the power supply is low. The power level will not reach the rated output. |
| Fault |
There are several possible causes for low output power. |
| |
|
| Solution |
- Check to verify the power supply controls and power set point are at the desired level.
- Check to ensure the power supply is not in a limit condition.
- Open the power supply door.
- Verify that the red LED, (D2), located on the control board is not energized.
- If the LED is energized, contact Enercon's Service Department for assistance.
- Check the corona treating station, verify the load is correct.
- Ensure the electrode bar area is sufficient for the power supply.
- The bare roll, ceramic electrode is capable of 60 watts per inch for the pair of electrodes in the assembly. Insufficient electrode area will cause a mismatch condition.
- For covered roll stations, the electrode area is determined by the roll dielectric covering, contact Enercon's Service Department for required areas.
- Verify the electrode air gap is set at .060" or 1.5mm.
- Verify the input voltage is at +/- 10% of the rated input on the power supply rating plate located inside the power supply door.
- The power reference signal supplied to the control board is determined by the voltage level supplied to U1. (Item 2)
- Verify the voltage level at U1, Pin 1 switches from +15VDC to a 0 volt level. To test, connect a DC volt meter positive lead to U1 Pin 1 and the common to TB1 Pin 6 on the control board.
- If the voltage level does not switch, check the ribbon cable plug connections on the control board and the membrane panel. (Item 19)
- Ensure the blue stripe on the ribbon cable is connected to Pin1 on both plugs.
- Replace the membrane assembly. (Item 1)
- If the voltage does switch, replace the control board. (Item 2)
- Contact Enercon's Service Department for assistance.
