POLARITY Indicators:
Green LEDs that indicate the polarity of the HV output voltage. One is for + polarity
and one is for –polarity.
Polarity indicators are always active whenever AC power is ON.
VOLTAGE/CURRENT Mode Indicators:
Green LEDs that indicate whether the output control is voltage or current. One LED
indicates voltage control and the other current control.
Mode indicators are always active whenever AC power is ON.
When in standby, the default will be the voltage control indicator no matter where
the control encoders or remote programming are set.
If CT operation is selected the current mode indicator will illuminate when latched.
If the arc option is provided, since it is neither voltage nor current mode, both the
voltage and current mode indicators will be lit. Pressing the standby switch will
provide a CT or arc latch reset.
FAULT Indicator:
Red LED that indicates a fault inside the unit. These faults will inhibit HV
generation. The fault indicator is functional whenever the AC power is ON.
Faults are defined as over temperature, fan failure, and under voltage/rail fault.
Interlock, CT and optional Arc trip are NOT considered faults.
STANDBY Pushbutton:
Pressing this switch will perform the following actions:
1.
The unit will be set to standby and the HV ON indicator will extinguish.
2.
A reset of the CT and/or arc latch option will be performed.
CONTROL LOCK Pushbutton:
Pressing this switch will lock the voltage and current encoders at their existing
settings so that turning their knobs will not change the settings. Press the switch
again to regain adjustment. This feature is to prevent accidental adjustment of the
HV output.
