1 Before switching on the Control Voltage[edit | edit source]
Disconnect at the Backside of the PNC the SubD 15Pol Connector before switching on the Control Voltage
The I/Os at the PNC are very sensitive to overvoltage or short circuit.
2 Electrical commissioning[edit | edit source]
- Check with your Multimeter at the SubD Plug that the Signals and connections is right
| Pin | Function | Notes |
|---|---|---|
| 1 | output of current monitor | 0...In corresponds to 0...10V (Ri = 4,7kΩ ) |
| 2 | output of voltage monitor | 0...Un corresponds to 0...10V (Ri = 4,7kΩ ) |
| 3 | common 0V-point | connected with earth |
| 4 | output of reference voltage | +10.00 V (max. 2 mA) |
| 5 | slider of current potentiometer | output |
| 6 | slider of voltage potentiometer | (optional) output |
| 7 | set value of current | input 0...10V corresp. to 0...In (Ri>100k? ) |
| 8 | set value of voltage | input 0...10V corresp. to 0...Un (Ri>100k? ) |
| 9 - 10 | input “STANDBY EXTERN“ | potential-free
contact, closed = Off |
| 11 - 12 | Short Cuircuit detection | potential-free
contact, closed = No Short circuit |
| 13 | DGND | digital ground |
| 14 | N.C. | |
| 15 | N.C. |
- Plug in the SubD
- Check the 230V connection at the bottom of the cabinet
- Check the grounding of the whole pinning system -> Pinning System
- Switch on the 230V Fuse in the cabinet and close the cabinet
3 Function Test[edit | edit source]
- Switch off the Generator at the Cabinet front side
- Turn both potentiometers to 0 and switch to interal
- Switch to negative Voltage Template:Image
- Set the pinning system at the PVSS to Service Mode
- Move the Chill Roll to work position
- Install a wire/band in the Pinning system
- Close both hoods and move the Pinning to Work position
- The Generator Power supply will be switched on automatically. If not, check the interlocks in PVSS
- Check HV to 10kV
- Switch on the PNC
- Switch on the HV (red button)
- Increase the HV current to about 1.0 at the potentiometer
- Increase the Voltage slowly to 10kV
- Check the Wire heating Template:Image
- Increase the Voltage of the LNG to 10V
- Check that you get a current. Otherwise one of the HV Plugs have no connection
