
REMOTE CONTROL: Remote control of the
HIGH VOLTAGE ON and HIGH VOLTAGE OFF
can be accomplished via the rear panel interface.
HIGH VOLTAGE OFF and HIGH VOLTAGE ON
can be controlled by momentary normally closed and
normally open contacts respectively. See Figure 3.4
on page 14 for the recommended interface.

EXTERNAL INHIBIT: Allows the user to inhibit
the power supply output without switching HIGH
VOLTAGE OFF control. This circuit can be used to
generate fast slewing output waveforms or control of
high voltage generation as in laser and capacitor
discharge applications. The maximum inhibit rate
should not exceed 5Hz. Consult the factory for
higher repetition rates or high pulse load
applications. See Figure 3.5 on 15 for the
recommended interface circuit.
IT IS EXTREMELY DANGEROUS TO USE THIS
INHIBIT CIRCUIT TO STOP HIGH VOLTAGE
GENERATION FOR THE PURPOSE OF
SERVICING OR APPROACHING ANY AREA
OR LOAD CONSIDERED UNSAFE
DURING NORMAL USE.

EXTERNAL INTERLOCK: External interlock
connections are provided on J3-3 and J3-4 on the 25
pin D connecter for connection to a safety interlock
switch. The unit will not operate unless the interlock
circuit is closed. If the interlock is not being used,
the jumper installed on the two pins before shipping
must be in place. If the jumper is missing, or there is
an opening between the interlock terminals high
voltage cannot be generated. During high voltage
operation if these connections are opened the unit
will revert to the HIGH VOLTAGE OFF mode.
Subsequent closing of the interlock circuit will NOT
return the unit to the HIGH VOLTAGE ON mode.
This must be accomplished by depressing the HIGH
VOLTAGE ON switch. See Figure 3.6 on page 15
for the recommended interface circuits.

ARC DETECT / ARC QUENCH / ARC COUNT :
The ARC INTERVENTION circuit senses dynamic
arcing or discharge conditions present at the output
load. If an arc occurs the output is inhibited for one
second, then the output is ramped up to the previous
set level. This ramp is based on the standard six
second slow start feature. The SLOW START ramp
circuit may be disabled by removing CR32 on the
Control/Power Pwb. Caution should be observed if
this feature is disabled. Discharge rates of greater
then 1Hz may cause excessive power dissipation in
the power supply’s output limiting resistors, voiding
the warranty.
The ARC COUNT feature will allow the user to program
the ARC fault parameters. The ARC indicator on the
front panel will illuminate for approximately one second
after each arc has occurred. The power supply can be
programmed to trip into the POWER DOWN mode if a
single arc occurs (AT Option).
The default setting is to trip the power supply into the
POWER DOWN mode if 8 arcs occur within a twenty
second period.

REMOTE HIGH VOLTAGE ON & REMOTE
HIGH VOLTAGE OFF
: Signals are provided for
remote monitoring of the HIGH VOLTAGE ON and
HIGH VOLTAGE OFF status. See Figure 3.7 on
page 16 for recommended interface.

REMOTE MODE INDICATORS: Signals are
provided for remote indication of the control mode
status: voltage control or current control. See Figure
3.8 on page 17 for the recommended interface.
