3.2.16.1 INTERNAL RELAY CONTROL
The internal relay contacts available at pins 6, 7 and 8 of the Analog I/O connector can be con-
figured from the front panel to operate in either Fault, Manual or List mode. If FAULT mode (the
factory default) is selected, the relay energizes automatically upon detection of a user-selected
condition. The selections are a)
NORM
(normal), a system fault (see PAR. 1.5.9), b)
V->C
, when
the unit transitions from Constant Voltage (CV) to Constant Current (CC) mode, or c)
C->V
,
when the unit transitions from CC to CV mode. If
V->C
(or
C->V )
is selected, the amount of
time the unit must be in CC (or CV) mode before the relay energizes may be programmed from
the front panel (see step 2a) or using the SCPI command
OUTP:PROT:DEL
(see KLP Devel-
oper’s Guide).
1. Enter
UTIL
menu (see PAR. 3.2.16, steps 1 through 3) and rotate either VOLTAGE or CUR-
RENT control until status display reads
RELY
. The DC VOLTS display indicates whether the
relay is currently
ON
(energized) or
OFF
(deenergized). Tap DC OUTPUT switch to enter
Relay Control menu.
• Rotate either VOLTAGE or CURRENT control to see the available relay control modes
in the status display. The modes are:
FLT
(factory default) - Relay is set to energize automatically upon detection of one of
three preselected conditions (tap DC OUTPUT to access FLT submenu):
NORM
: (factory default) relay energizes immediately upon detection of a system
error:
V->C
: relay energizes immediately upon detection of a system error and, after
a user-programmable delay, the relay energizes upon a transition
from constant voltage (CV) to constant current (CC) mode.
C->V
: relay energizes immediately upon detection of a system error and, after
a user-programmable delay, the relay energizes upon a transition
from constant current (CC) to constant voltage (CV) mode.
RTN
: Return to
FLT
menu.
MAN -
Relay on/off is controlled manually, directly from the front panel (see below).
Relay state is not retained; relay will be off when unit is turned on
LIST
- Relay on/off is controlled remotely using LIST commands via GPIB or RS 232
interface (see KLP Developer’s Guide).
RTN -
Return to
RELY
menu.
2. To select mode rotate either VOLTAGE or CURRENT control until status display reads
FLT
(factory),
MAN
(manual), or
LIST
. Then press DC OUTPUT switch to save selection.
a. If
FLT
is selected, rotate VOLTAGE or CURRENT control to select
NORM
,
V->C
, or
C->V
. in the status display.
