6. LOCAL OPERATION

HIGH VOLTAGES MAY POTENTIALLY EXIST FROM THIS POINT FORWARD.
ENSURE HV OUTPUT IS IN THE OFF POSITION BEFORE COMMENCING.
Follow the steps below to operate the PHV supply in Local mode.
6.1.

Set the Control Mode

If an optional interface is installed, ensure front panel LOCAL/REMOTE switch is depressed
and the unit is in Local Mode (Item 18 in Figure 1).
6.2.

Turn on AC power

Turn ON the POWER switch (Item 11 in Figure 1). The HV output will remain OFF, and the
Local LED (Item 17 in Figure 1) illuminates, indicating local operation.
6.3.

Select desired output polarity

If optional polarity reversal is installed (Item 16 in Figure 1), set the switch to the desired
position.
6.4.

Set the output OVP Limit

With the OUTPUT OFF, turn the voltage potentiometer (Item 4 in Figure 1) clockwise to its
limit and push the SET VALUES switch to display set values (display flashes). Using a
screwdriver, adjust the OVP Set Point with the V-LIMIT potentiometer (Item 6 in Figure 1).
The V-LIMIT LED illuminates and the limit voltage is displayed on the VOLTAGE meter.
To operate with no output voltage limit, turn the V-LIMIT potentiometer fully clockwise. The
V-LIMIT LED will extinguish.
Once the OVP limit has been set, turn the VOLTAGE potentiometer back to the desired set
point and switch display mode to actual values by pressing SET VALUES (Item 7 in Figure
1).
Note: OVP is always active in LOCAL, REMOTE, Analog or Digital programming modes.
6.5.

Set the desired output voltage/current levels

To set the output voltage/current, push the SET VALUES (Item 7 in Figure 1) button, and the
voltage/current displays will Flash and show the set points. To display the setpoint
continuously, push and hold the SET VALUES button for approximately 2 seconds.
Adjust the Voltage and Current potentiometers (Items 4/9 in Figure 1) to the desired values.
Push the SET VALUES button again to return to the actual output mode (the displays will not
flash). The potentiometers provide an adjustment range from approximately 0.1% to 100% of
the rated value.
6.6.

Turning ON the output

After adjusting the SET VALUES, the output can be turned on by pushing the OUTPUT
button (Item 13 in Figure 1). The ON LED will illuminate (Item 12 in Figure 1) to show the HV
output is ON.
