Command Description
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?
Returns the output On/Off status string.
ON- output on. OFF- output off.
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
protection and re-arm it, while FLD 0 will cancel the protection.
FLD?
Returns the Foldback protection status string:
“ON”- Foldback is armed, “OFF”- Foldback is canceled.
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 and recovered at AC
power up.
FBD? Supply returns the value of the added Fold Back Delay.
FBDRST Reset the added Fold Back Delay to zero.
OVP n
Sets the OVP level. The OVP setting range is given in Table 7-8. The number of characters
after OVP is up to 12. The minimum setting level is approx. 105% of the set output voltage,
or the value in Table 7-8, whichever is higher. Attempting to program the OVP below this
level will result in execution error response (”E04”). The OVP setting stays unchanged.
OVP?
Returns the setting “n” where “n” is the exact string in the user’s “OVP n”. When in Local mode,
returns the last setting from the front panel in a 4 digit string.
OVM Sets OVP level to the maximum level. Refer to Table 7-8.
UVL n
Sets Under Voltage Limit. Maximum value of “n” is 5% below PV setting, but returns “E06” if
higher. Refer to Table 7-9 for UVL programming range.
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.
When UVP is activated, returns the setting
UVP n
Sets Under Voltage Protection. Maximum value of “n” is 5% below PV setting, but returns
“E06” if higher. Refer to Table 7-9 for UVP programming range.
UVP?
Returns the setting “n” where “n” is the exact string in the user’s “UVP n”. When in
Local mode, returns the last setting from the front panel in a 4 digit string.
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.
AST? Returns the string auto-restart mode status.
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.
RCL Recalls last settings. Settings are from the last power-down or from the last “SAV” command.
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”.
MS? Returns the Master/Slave setting. Master: n = 1..... 6 Slave: n = 0
NOTES:
1. In Advanced Parallel mode (Refer to Sec. 5.5.3.1), “n” is the total system current.
2. In Advanced Parallel mode, “MC?” returns the Master unit current multiplied by the number of
Slave units.
3. UVL? will return “C01” if UVP is activated and vice versa.
