X2364 MANUAL

118044-001 REV E
WARNING
THE VOLTMETER ON THE POWER SUPPLY
FRONT PANEL DOES NOT READ THE OUTPUT
VOLTAGE WHEN THE POWER IS TURNED OFF,
EVEN IF A CHARGE STILL EXISTS ON THE
LOAD.
CAUTION
ALWAYS OPERATE THE UNIT WITH THE COVER
ON.
A fan maintains safe operating temperature in the X2364
power supply by drawing air over the circuit components.
The cover must be on in order to direct the airflow over
the areas that need cooling. In operation, the unit must be
places so that the air intake and the fan exhaust are clear
of any obstructions that might impede the flow of air.
3.2 Standard Features
A note on remote signal grounding. Whenever
applicable, electrical isolation should be provided when
interfacing with any high voltage power supply. For
power control signals such as EXTERNAL
INTERLOCK, COOLING FAULT and Fail Safe Lamp
isolated relay contacts or switches should be used.
Spellman application engineers are available to assist in
interface circuitry design. All interface cables should be
properly shielded.
REMOTE CONTROL via RS232 Interface:
Please
refer to the RS232 Interface Manual incorporated herein.
EXTERNAL INTERLOCKS:
Interlock connections are
provided on the terminal on the rear of the chassis for
connection to a safety switch. The unit will not operate
unless the interlock circuit is closed. If the interlock is
not being used, the jumper installed on the terminals. If
there is an open between the interlock terminals the unit’s
high voltage inverter will be disabled. During high
voltage operation, opening the interlock circuit will cause
the unit to revert to the HIGH VOLTAGE OFF mode.
Subsequent closing of the interlock circuit will NOT
return the unit to HIGH VOLTAGE ON mode, this must
be accomplished by depressing the HIGH VOLTAGE ON
switch. See Figure 3.2 for the recommended interface
circuit.
ARC DETECT / ARC QUENCH ARC COUNT:
The
ARC DETECT circuit senses dynamic arcing or discharge
conditions present at the output load. If an arc occurs, the
output is inhibited for one second. After the one-second
period, the output is ramped up to the previous set level.
This ramp is based on the standard six-second slow start
feature. The ARC DETECT ramp circuit may be disabled
by removing CR35 on the Control/Power PWB. Caution
should be observed if this feature is disabled. Discharge
rates of greater than 1 Hz may cause excessive power
dissipation in the power supply’s output limiting resistors.
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 to the POWER DOWN mode if an arc
occurs. The standard feature is programmed to trip the
power supply if 8 arcs occur within a twenty second
period.
FAIL SAFE LAMP INDICATOR:
A Fail Safe
Lamp indicator for remote indication of HV ON mode.
The lamp is ON when HV is ON. If the lamp becomes
defective or is not connected, the HV is disabled and the
INTLK OPEN on the front panel is lit. The lamp rating
must be 12V, 120mA. See Figure 3.3 for recommended
interface.
