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 (fatal) 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.
(1) To select
NORM
, tap the DC OUTPUT switch to save selection; unit returns to
RELY
menu.
(2) To select
V->C
or
C->V
, first set the delay. While
V->C
or
C->V
is in the status dis-
play, the DC AMPERES display shows the delay in seconds, from 000.5 to 128.0:
NNND
, where
NNN
is an integer from 0 to 128 and
D
will be either .0 or .5 (000.0 is
not permitted). The delay determines the length of time that the unit must be operat-
ing in the new mode before energizing the relay.
The factory default delay time is set to 1.0 seconds to prevent false tripping of the
relay during application of output power to low impedance or highly reactive loads. If
false tripping occurs, this delay may be increased as needed.
To change the delay, press in and rotate either the VOLTAGE or CURRENT con-
trol; release the control when the DC AMPERES display shows the desired delay.
Tap the DC OUTPUT switch to save selection; unit returns to
RELY
menu.
NOTE: Once the relay turns on in
V->C
or
C->V
mode, the relay will go off again when the
unit transitions back to the original mode, or when the output is turned off.
b. To select
MAN
, tap the DC OUTPUT switch to save selection. If
MAN
is selected, the DC
VOLTS display shows whether the relay is
ON
or
OFF
. To change the state of the relay
press in and rotate either VOLTAGE or CURRENT control until the desired relay state
is displayed, then release the control. Tap the DC OUTPUT switch to immediately set
the relay to the selected state and return to the
RELY
menu.
c. To select
LIST
, tap the DC OUTPUT switch to save selection; unit returns to the
RELY
menu
3. Rotate either VOLTAGE or CURRENT control until status display shows
RTN
and press DC
OUTPUT switch to exit UTIL menu, then rotate either VOLTAGE or CURRENT control until
status display shows
EXIT
and press DC OUTPUT switch to exit FUNCTION control.
