J3-9 V-MONITOR
A 0-10V positive signal with respect to SIGNAL COMMON, in direct proportion to
the output voltage, is available at this terminal. An internal 10 k ohm, 1%, limiting
resistance protects the circuitry. Therefore, it is recommended that a digital
voltmeter be used to monitor this output. It is also acceptable to use a 1 mA DC full
scale instrument (i.e. analog meter) for monitor purposes (See INTERFACE
DIAGRAM FIG 5).
J3-6 REMOTE V-PROGRAM
Note: When the PROGRAM REM/LOC switch is set to
the LOCAL position, this input is disconnected and
output voltage programming is set by the front panel
control.
When PROGRAM REM/LOC switch is set to the
REMOTE position, and a digital signal connection is
not made, program voltages must be provided to the
REMOTE V-PROGRAM and I-PROGRAM inputs of J3
in order for high voltage to be generated.
"NC" OPTION USERS: Programming is always
remote, no switch is provided.
When the PROGRAM REM/LOC switch is set to the REMOTE position, a positive
0-10 V signal (with respect to SIGNAL COMMON at J3-8) will program the output
voltage proportionally from zero to rated output. This input can be programmed in
several ways (See INTERFACE DIAGRAM FIG 3):
* A user supplied 0 - +10 V signal.
* A user supplied potentiometer (5-50 k ohms, 10 k nominal) can be connected
between the +10 V REFERENCE and SIGNAL COMMON, with the wiper
connected to the REMOTE V-PROGRAM terminal.
* The REMOTE V-PROGRAM input may be jumpered to the +10 V
REFERENCE voltage terminals for a fixed output at the maximum voltage.
J3-12 +10 V REFERENCE
The output of this terminal is an ultra-stable, positive, +10 V reference voltage (with
respect to SIGNAL COMMON) that is supplied for user programming applications.
Maximum current drain from this point should be limited to 4 mA.
