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 Cu
r-
rent, Over
Voltage Set Point and Under Voltage Set Point.
Example: 5.9999,6.0000,010.02,010.00,7.500,0.000
8
FILTER
nn
Set the low pass filter frequency of the A to D Converter for Voltage and Current
Measurement where nn = 18, 23 or 46.
9
FILTER?
Returns the A to
D Converter filter frequency: 18,23 or 46 Hz.
10
OUT n
Turns the output to ON or OFF. Recover from Safe
-
Start, OVP or FLD fault.
OUT 1 (or OUT ON)
-
Turn On.
OUT 0 (or OUT OFF)
-
Turn Off
11
OUT?
Returns the output On/Off status string.
ON
-
output On.
OFF
-
output Off.
12
FLD n
Sets the Foldback protection to ON or OFF.
FLD 1 (or FOLD ON)
-
Arms the Foldback protection
FLD 0 (or FOLD OFF)
-
Cancels the Foldback protection.
When the Foldback protection has been activated, OUT 1 command will release
the
pr
o
tection and re
-
arm it, while FLD 0 will cancel the protection.
13
FLD?
Returns the Foldback protection status string:
“ON”
-
Foldback is armed. “OFF”
-
Foldback is cancelled.
14
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 at AC
power down and recovered at AC powerup.
15
FBD ?
Supply returns the value of the added Fold Back Delay.
16
FBDRST
Reset the added Fold Back Delay to zero.
17
OVP n
Sets the OVP level. The OVP setting range is given in Table 7
-
7. 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
-
7, whichever is
higher. The m
aximum OVP setting level is shown in Table 5
-
1. Attempting to
program the OVP below this level will result in an execution error response
(“E04”). The OVP setting stays u
n
changed.
18
OVP?
Returns the setting “n” where “n” is the exact string in the user’s
“OVP n”. When
in L
o
cal mode, returns the last setting from the front panel in a 4 digit string.
19
OVM
Sets OVP level to the maximum level. Refer to Table 7
-
7.
20
UVL n
Sets Under Voltage Limit. Value of “n” may be equal to PV setting, but returns
“E06”
if higher. Refer to Table 7
-
8 for UVL programming range.
21
UVL?
Returns the setting “n” where “n” is the exact string in the user’s “UVL n”. When
in Local mode, returns the last setting from the front panel in a 4 digit string.
22
AST n
Sets the Auto
-
r
estart mode to ON or OFF.
AST 1 (or AST ON): Auto restart On.
AST 0 (or AST OFF): Auto restart Off.
23
AST?
Returns the string auto
-
restart mode status.
24
SAV
Saves present settings. The settings are the same as power
-
down last setting.
These se
t
tings a
re erased when the supply power is switched Off and the new
“last settings” are saved.
25
RCL
Recalls last settings. Settings are from the last power
-
down or from the last
“SAV” command.
