D)
Set the current programming level (J1-9) to just
above the current anticipated that will be drawn
from the power supply.
E)
Slowly increase the voltage programming (J1-4)
while monitoring the voltage and current
monitors (J1-10 and J1-11
respectively).
Carefully note proper equipment operation and
that the load is behaving as predicted.
F)
To turn the HV OFF, open the Enable Input (J1-
8). If the equipment is to be left off for an
extended period of time or service of the unit or
load is required
,
turn off the input power.
WARNING!
After turn
off,
do not touch anything that has
been connected to the output of the power
supply. Wait a minimum of 5 minutes, and then
discharge any remaining stored energy by
connecting the high voltage output to ground.
Failure to follow these safety warnings can result
in injury or death.
3.2 Standard Features
Programming and monitoring of the V6 Series is
accomplished via the use of conventional positive
polarity, ground referenced signals. All signal inputs and
outputs are noise filtered, impedance protected and diode
clamped providing an easy to use, robust analog customer
interface. Excellent results have been obtained via the use
of standard engineering design guidelines like twisted
pair, shielded cables, the prudent dressing of interface
wiring away from possible noise sources, short cable runs
and adhering to a well thought out and executed
grounding topology.
REMOTE PROGRAMMING
The V6’s programming and monitor signals are based
upon a universal, positive polarity, ground referenced
signal such that 0 to 5Vdc corresponds to 0 to 100% rated
output.
Programming can be accomplished via the use of an
applicable customer provided ground referenced voltage
source that meets the mentioned requirements. See Figure
4 for details.
If such a source is not available a pre5Vdc
reference is provided on J1-7. A simple adjustable voltage
divider can be created using this reference and an external
potentiometer(s) which will provide full control of the
voltage and current loops.
See Figure 5 for details.
LOCAL PROGRAMMING
Local programming can be accomplished via the use the
multi turn potentiometer on the top of the unit.
Continuous multi-turn precision potentiometers directly
dial the output voltage. The resolution of the pot is 0.05%
of maximum. The potentiometers are screwdriver
adjustable and easily accessed. For local voltage control
the following pins must be shorted: J1-1 to J1-5, J1-7 to
J1-9. See Figure 6 for details.
REMOTE MONITORING
The voltage and current monitor signals have adequate
bandwidth capability to accurately represent the actual
respective output within the dynamic limits of the power
supply. See Figure 7 for details.
ENABLE INPUT
The enable input signal provides simple control of the
ON/OFF functionality of the high voltage output. See
Figure 8 for details.
WARNING!
It is extremely dangerous to use this circuit to
inhibit high voltage generation for the purpose of
servicing or approaching any area considered
unsafe during normal usage.
