118128-001 Rev A
Set the front panel controls to:
a. Power Switch - OFF
b. Output Voltage Switch(s) – 0 (205B
only).
c. Multi Turn Digital Dial - 000 (fully
counterclockwise)
Set the LOCAL/REMOTE (ANALOG/
DIGITAL) rear panel switches (205B only) to:
a. LOCAL for local front panel
operation.
b. REMOTE/ANALOG for remote
analog operation. Note: Selecting the
REMOTE control will override all local
front panel controls of the output.
c. REMOTE/DIGITAL for Computer
Programming if equipped with a CBNY
option. Reference Section 2.7.
Plug the line cord into the power line with a
three-wire IEC receptacle to maintain proper
case ground.
WARNING!
This unit is equipped with a
three-wire grounded line cord. This must be
used with a three-wire receptacle where the
"third wire" is connected to earth ground;
otherwise personal injury or death may occur.
Connect the output of the Series 230 to the
circuit. Use a properly rated shielded cable with
the supplied HV output connector to insure good
circuit connections and safe operation. Refer to
Section 2.10.
WARNING!
Prior to connecting or removing
any equipment from the High Voltage power
supply, always return the Output Voltage
Control(s) to 0V prior to applying or removing
power. External circuits may retain voltage
after controls are set to zero. Discharge any
residual voltage before connecting or removing
any equipment.
2.6 LOCAL OPERATION
Turn POWER - ON to the instrument. Slowly
increase the output voltage using the appropriate
Voltage Control(s) until the desired output level
is reached. Apply power to the load by
switching the High Voltage - ON. The output
will quickly reach the value set by the controls.
Full stability will be achieved after
approximately 30 minutes.
2.7 REMOTE OPERATION
PROGRAM CONTROL SWITCH:
Before the Series 230 can be remotely
programmed, the instrument must be configured
by setting the rear panel PROGRAM
CONTROL SWITCH (S102) to the REMOTE
ANALOG position (206B is only programmable
through the rear panel and therefore S101 is
omitted). All monitoring and enable functions
are active, independent of the S102 switch, as
are the front panel meters. When in remote
mode the front panel controls are inactive.
REMOTE PROGRAMMING:
The high voltage output can be remotely
programmed from either an external voltage
source or with an external potentiometer using
the internal reference voltage source (Pin 4). A
0 to +5Vdc programming voltage applied to Pin
6 of J107 (PROGRAMMING/MONITOR)
connector jack on the rear panel will remotely
program the high voltage output from zero to
maximum output. Programming can also be
accomplished using a potentiometer connected
between Pin 4 (+5Vdc), Pin 7 (GND) and with
the wiper connected to Pin 6 (PRGM INPUT).
The potentiometer should be a low temperature
coefficient wirewound or cermet type, 5k
:
to
20k
:
resistance values. The power supply
output will be proportional to the programming
input. The programming input impedance is
greater than 1M

. TABLE 2.1 below lists the
PROGRAMMING / MONITOR connector pin
designations. The accuracy of the remote
programming is detailed in the specifications.
