Connector pinouts
Monitor (J1)
J1 provides access to metering output signals and the safety interlock input signal.
| Pin | Name | Function | Usage |
|---|---|---|---|
| 1 | RETURN | Signal ground | Ground reference for meter outputs (kV MON, mA MON) |
| 2 | kV MON | HV meter (out) | 0 to +10 V = 0 to +50 kV out |
| 3 | mA MON | Beam meter (out) | 0 to +10 V = 0 to 1 mA out |
| 4 | INTLK | Safety interlock (in) | Short to pin 1 to enable HV output; leave open to disable HV output |
Control (J2)
J2 provides access to power supply control signals.
| Pin | Name | Function | Usage |
|---|---|---|---|
| 1 | VREF | 10V reference (out) | Reference voltage for external circuitry; 10 mA maximum. |
| 2 | NC | No connect | |
| 3 | ISET | Beam setpoint (in) | Beam control voltage: 0 to +10V = 0 to 1 mA out. Local control: connect to pin 4. Remote control: connect to external 0 to +10V source. |
| 4 | IPOT | Beam control pot (out) | Local control: connect to pin 3. Remote control: leave disconnected. |
| 5 | NC | No connect | |
| 6 | VSET | HV setpoint (in) | HV control voltage: 0 to +10 V = 0 to +50 kV out. Local control: connect to pin 7. Remote control: connect to external 0 to +10V source. |
| 7 | VPOT | HV control pot (out) | Local control: connect to pin 6. Remote control: leave disconnected. |
| 8 | RETURN | Signal ground | Ground reference for VREF, VPGM and IPGM. |
| 9 | RETURN | Signal ground | Ground reference for VREF, VPGM and IPGM. |
Wiring diagrams
Model XPS50P50 can either be controlled locally, by adjusting its internal trimpots, or remotely by connecting it to external programming voltages. In both cases, the output voltage and beam current may be externally monitored by connecting meters (or analog-to-digital converters) to J1 pins 2 and 3.
