uX MANUAL 7 118151-001 REV A
WARNING
AFTER TURNOFF, DO NOT HANDLE
THE LOAD UNTIL THE CAPACITANCE
HAS BEEN DISCHARGED!
LOAD CAPACITANCE MAY BE DISCHARGED BY
SHORTING TO GROUND.
WARNUNG
Nach drm Ausschalten des Gerätes die Last erst
berühren wenn diese vollständig entladen ist.
Die elektrische Kapazität der Last kann durch
einen Kurzschluß zur Erde entladen werden.
WARNING
THE VOLTAGE MONITOR DOES NOT READ THE
OUTPUT VOLTAGE WHEN THE POWER IS
TURNED OFF, EVEN IF A CHARGE STILL EXISTS
ON THE LOAD.
WARNUNG
Der Spannungsmonitor arbeitet nicht bei
abgeschalteter Versorgungspannung, auch nicht
wenn die Last noch aufgeladen ist.
CAUTION
ALWAYS OPERATE THE UNIT WITH THE COVER
ON. DO NOT ATTEMPT TO ACCESS OR REPAIR
ANY INTERNAL CIRCUITS. DANGEROUS AND
LETHAL VOLTAGES ARE GENERATED INSIDE
THE MODULE.
CAUTION
Betreiben Sie das Hochspannungsnetzteil
ausschließlich mit geschlossenem Gehäuse.
Versuchen Sie nicht die internen Schaltkreise zu
berühren oder zu reparieren, da
lebensgefährliche Hochspannungen in Innern
erzeugt werden.
3.2 Standard Features
A note on remote interface circuitry and remote signal
grounding. Whenever possible, electrical isolation should
be provided when interfacing with any high voltage
power supply. For power control signals such as
EXTERNAL INTERLOCK, HIGH VOLTAGE OFF and
HIGH VOLTAGE ON isolated relay contacts should be
used. If possible, analog programming and monitoring
signals should be isolated via analog isolation amplifiers.
Spellman application engineers are available to assist in
interface circuitry design. All interface cables should be
properly shielded. All power supply signals should be
referenced to the power supplies signal ground.
LOCAL AND REMOTE PROGRAMMING:
Allows
the operator to select local or remote adjustment of the
output voltage and current. Adjustments are made using
the screwdriver adjustable potentiometers accessible
through the top cover of the power supply or via an
external voltage source provided by the operator. In local
control jumpers are installed on the 15 pin interface
connector between pin 7 and pin 8 for voltage control and
between pin 10 and pin 11 for current control.
For remote programming, the jumpers are removed and a
positive voltage source, from 0 to 10 volts, is applied to
the appropriate terminals. Programming signals should be
referenced to signal ground. By adjusting the voltage
source from 0 volts (zero output) to 10 volts (full rated
output) the desired output can be selected. 0 to 5 volts
equals 0-100% of output on units with 5VPM option. See
Figure 3.4 for wiring diagram and specifications.
An alternate method of controlling the output remotely is
by using external resistance such as a potentiometer or a
resistor network. For remote control the jumpers are
removed and the desired resistor configuration is
installed. See Figure 3.4 for wiring diagram.
REMOTE MONITOR:
Test points are made available
on the 15 pin D connector for monitoring the voltage,
current and filament outputs and for reading the filament
current limit and preheat set points. The test points are
always positive regardless of the output polarity, where 0
to 10 volts equals 0-100% of output on standard units. 0
to 5 volts equals 0-100% of output on units with 5VPM
option. Test points have an output impedance of 1K
ohms. See Figure 3.3 for test point designation.
EXTERNAL INTERLOCK:
Interlock connections are
provided on the 15 pin D connector for connection to a
safety switch. The unit will not operate unless the
interlock circuit is closed. During high voltage operation,
opening the interlock circuit will cause the unit to revert
to the HIGH VOLTAGE OFF mode. See Figure 3.3 for
the recommended interface circuit.
