Setting A Maximum Limit For Output Voltage; Strike Voltage Limits - Advanced Energy Pinnacle User Manual

Pinnacle™ 20 kW
This function lets you select a maximum strike voltage.
Note: The strike limit controls the level of the strike/ignition voltage but also impacts
the initial power overshoot experienced when requesting low setpoints. For
example, with a strike voltage limit setting of "high," you may observe a
significant overshoot when requesting a low power. If ignition is not difficult
the user can select "medium" or "low" to reduce the effects of overshoot.
Note: High voltage output units (750–1500 VDC and 1500–3000 VDC) do not have
strike voltage capability.
To set the strike voltage limit:
1. Press the PROCESS soft key at the main menu.
2. Press the LIMITS soft key.
3. Press the STRIKE soft key.
4. Rotate the MODIFY knob to select "Low," Medium," or "High." (The values
associated with each selection depend on the output impedance range of your unit.
See the following table for specific values.)
5. Press ENTER to accept and exit.

SETTING A MAXIMUM LIMIT FOR OUTPUT VOLTAGE

PROCESS → LIMITS → VOLTAGE
This function lets you set a maximum limit for output voltage. The maximum
allowable value is the maximum rated output for the supply.
To set the user voltage limit:
1. Press PROCESS → LIMITS → VOLTAGE.
2. Rotate the MODIFY knob to select a value between 0 and the maximum rated
output voltage for the supply.
3. Press ENTER to accept and exit.
