#
Command
Description
7
DVC?
Display Voltage and Current data. Data will be returned as a string of ASCII characters. A
comma will separate the different fields. The fields, in order, are: Measured Voltage,
Programmed Voltage, Measured Current, Programmed Current, Over-Voltage Set Point
and Under-Voltage Set Point.
Example
: 5.9999,6.0000,010.02,010.00,7.500,0.000
8
OUT n
Turns the output to
ON
or
OFF
. Recover from Safe-Start, OVP or FLD fault.
OUT 1
(or
OUT ON
): Turn Output
ON
;
OUT 0
(or
OUT OFF
): Turn Output
OFF
9
OUT?
Returns the Output
ON/OFF
status string.
ON
: Output
ON
.
OFF
: Output
OFF
.
10
FLD n
Sets the
FOLD
back protection to
ON
or
OFF
.
FLD 1
(or
FOLD ON
) - Arms the
FOLD
back protection
FLD 0
(or
FOLD OFF
) - Cancels the
FOLD
back protection.
When the Foldback protection has been activated, the
FLD 1
command will release the
protection and re-arm it, while the
FLD 0
command will cancel the protection.
11
FLD?
Returns the
FOLD
back protection status string:
ON
:
FOLD
back is armed.
OFF
:
FOLD
back is cancelled.
12
FBD nn
Add (nn x 0.1) seconds to the
FOLD
back Delay. This delay is in addition to the standard
delay. The range of nn is 0 to 255. The value is stored in EPROM memory at AC Input
power down and recovered at AC Input power up.
13
FBD ?
Returns the value of the added
FOLD
back Delay.
14
FBDRST
Resets the added
FOLD
back Delay to zero.
15
OVP n
Sets the
OVP
level. The
OVP
setting range is given in Table 7-5. The number of
characters after
OVP
is up to 12. The minimum setting level is approximately 105% of the
Output voltage setting, or the value in Table 7-6, whichever is higher. The maximum
setting level is shown in Table 5-1. Attempting to program the
OVP
below this level will
result in an e
xecution error response (“
E04
”) and the
OVP
setting stays unchanged.
16
OVP?
Returns the setting “
n
” where “
n
” is the exact string from the “
OVP n
” command. When in
Local
mode, returns the last setting from the front panel in a 4 digit string.
17
OVM
Sets
OVP
level to the maximum level. Refer to Table 7-5.
18
UVL n
Sets the Under Voltage Limit level
. Value of “
n
” may be equal to the
PV
setting, but
returns “
E06
” if higher. Refer to Table 7-6 for
UVL
programming range.
19
UVL?
Returns the setting “
n
” where “
n
” is the exact string from the “
UVL n
” command. When in
Local
mode, returns the last setting from the front panel in a 4 digit string.
20
AST n
Sets the
Auto-Restart
mode to
ON
or
OFF
.
AST 1
(or
AST ON
): Auto-Restart
ON
.
AST 0
(or
AST OFF
): Auto restart
OFF
.
21
AST?
Returns the string Auto-Restart mode status.
22
SAV
Saves “Present Settings”. The “Present Settings” are the same as power-down “Last
Settings
”. These settings are erased when the power supply AC Input power is switched
OFF and the
new “Last Settings” are saved.
23
RCL
Recalls
“Last Settings”. Settings are from the last AC Input power-down or from the last
“
SAV
” command.
24
MODE?
Returns the power supply operation mode. When the power supply Output is
ON
(
OUT 1
)
it will return “
CV
” or “
CC
”. When the power supply Output is
OFF
(
OUT 0
) it will return
“
OFF
”.
25
MS?
Returns the unit Master/Slave setting. Master: n = 1, 2, 3, or 4 Slave: n = 0
