J3-7
REMOTE I-PROGRAM
Note: When the PROGRAM REM/LOC switch is set to
the LOCAL position, this input is disconnected and
output current programming is set by the front panel
control.
When the 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
current proportionally from zero to rated output. This input can be programmed in
several ways
(See INTERFACE DIAGRAM FIG 4)
:
*
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 I-PROGRAM terminal.
*
The REMOTE I-PROGRAM input may be jumpered to the +10 V
REFERENCE voltage terminal for a fixed current limit at the maximum rated
current.
J3-3
INTERLOCK
INTERLOCK (J3-3) must be jumped to DIGITAL COMMON (J3-11) to enable the
supply. If desired, this jumper may be removed and replaced by an external switch
which must be closed for the supply to operate. If the external switch is opened, the
supply will return to standby and HV generation will be inhibited. When the switch
is again closed, the front panel HV ON pushbutton must be depressed or Remote HV
ON terminals J3-15 and J3-16 must be momentarily connected to re-enable the
supply (except on “NC” option supplies which will re-enable immediately)
(See INTERFACE DIAGRAM FIG 1)
