Command
Description
11
OVP n
Sets the OVP level.
◆
The OVP setting range is given in Table 6-6.
The number of characters after OVP is up to 12.
The minimum setting level is 5% of full rating plus the output voltage set value.
Attempting to program the OVP below this level will result in execution error response
(“E04”). The OVP setting stays unchanged.
12
OVP?
Returns the setting “n” where “n” is the exact string in the user’s “OVO n”. When in Local
mode, returns the last setting from the front panel in a 4 digit string.
13
OVM
Sets OVP level to the maximum level.
◆
Refer to Table 6-6.
14
UVL n
Sets Under Voltage Limit.
Value of “n” may be equal to PV setting, but returns “E06” if
higher.
◆
Refer to Table 6-7 for UVL programming range.
15
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.
16
ASTn
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.
17
AST?
Returns the string auto-restart mode status.
“ON”-Auto restart is on.
“OFF”-Auto restart is off.
18
SAV
Saves present settings. The settings are the same as power-down last settings.
These settings are erased when the supply power is switched off and the new “last settings”
are saved.
19
RCL
Recalls last settings.
Settings are from the last power-
down or from the last “SAV” command.
20
MODE?
Returns the power supply operation mode. When the power supply is ON (OUT 1) it will
return “CV” or “CC”. When the power supply is OFF (OUT 0) it will return “OFF”.
6-6-5. Global output commands
All supplies, even if not the currently addressed supply, receiving a global command will execute the command.
No response to the PC issuing the command will be returned to the PC. The PC is suing the command will be
responsible to delay and any other communications until the command is execute. 200 Ms minimum is the
suggested delay. If the command contains an error, out of range values for example, no error report will be sent to
the issuing PC.
No.
Command
Description
1
GRST
Reset. Brings the power supply to a safe and known state:
Output voltage: 0V, output current: 0A, out: OFF, Remote: RMT 1
’
AST: OFF PVP: Max. UVL: 0
The conditional register (FLT and STAT) are updated. Other registers are not changed.
Non-Latching faults (FB, OVP, SO) are cleared, OUT fault stays.
2
GPV n
Sets the output voltage value in volts. The range of voltage values is shown in Table 6-3
‘
n
’
may be up to 12 char plus dec. pt
3
GPC n
Program the output current value in amperes. The range of current values is shown in Table
6-4
‘
n
’
may be up to 12 char plus dec. pt
4
GOUT
Tums the output to ON or OFF:
“OUT 1/ON”= turn on
“OUT 0/OFF”= turn off, clears CV and CC bits in the Status Condition (STAT)
OUT ON will respond with
“E07” if the output can not be turned on because of a latching fault
(OTP < AC, ENA, SO) shut down.
5
GSAV
Save present settings.
Same settings as power-down last settings listed in Error! Reference source not found.
Except the address and baud rate are not saved. Saves to the RAM. These settings are
erased when the supply power is switched off and the new
‘
last settings
’
are saved.
6
GRCL
Recall last settings. Settings are from last power-down or from last
‘
SAV
’
or
‘
GSAV
’
command.
Address and baud rate are not recalled so communication is not interrupted.
