Remote Functions
Several functions may be controlled remotely through the 25-pin D-Sub connector
located on the rear of the unit (the mating D-Sub connector and back shell are
supplied in the mounting kit with each unit):
• Turning On/Off the High Voltage Output
• Controlling the Voltage and Current Setpoints
• Monitoring the Output Voltage, Current, and Alarms
Turning On/Off the High Voltage Output Remotely
1. The Remote On/Off function enables the power supply to be energized from a
remote location. This function switches the output voltage On/Off, NOT THE
AC MAIN VOLTAGE.
NOTE
- The VCM Power Supply needs 60ms to reach maximum output
voltage from 0 kV. The time needed to reach 0kV from the maximum
depends on the load connected.
2. To enable/disable the remote On/Off function:
• Press [MENU + ENTER] for the Advanced Settings
• Press [MENU] until “REMOTE ON-OFF” is displayed
• Press [DOWN] to toggle from “DISABLE” to “ENABLE”
• Press [ENTER] to accept the setting (asterisk will flash)
• Press [MENU + UP] to return to the Main Screen
3. Provide a dry contact between D-Sub connector pins 1 & 7.
4. Jumper D-Sub connector pins 14 & 20 to make available 12V with which
power to the contact.
5. Closing the contact will then energize the high voltage output; while an open
circuit will deenergize it.
NOTE
- If the remote On/Off function is used, the Power switch must
remain in the “ON”, (I), position.
NOTE
- If the remote On/Off function is used, the [RUN] button can be
used to temporary activate the output voltage manually for testing or
verification purposes.
Controlling the Voltage Setpoint Remotely
1. The output voltage can be controlled from a remote source that provides any of
the following control signals:
• 0-5 VDC
• 0-10 VDC
• 0-20 mA DC
• 4-20 mA DC
