Series 2268 850 Watt DC Power Supplies Reference Manual Error Messages
2268S-901-01 Rev. A / January 2015 245
Execution Error List
An error in the range [-299, -200] indicates that an error has been detected by the instrument's
execution control block. The occurrence of any error in the class causes the execution error
bit (bit 4) in the Event Status Register to be set.
Execution errors are reported by the device after rounding and expression evaluation
operations have taken place.

Code Error Message Description
-200 Execution Error This is the generic syntax error for devices that
cannot detect more specific errors. This code indicates only that
an Execution Error as defined in
IEEE 488.2,
11.5.1.1.5 has
occurred.
-203 Command protected Indicates that a legal password-protected
program command or query could not be executed because the
command was disabled. Check the calibration state.
-220 Parameter error Indicates that a program data element related
error has occurred
-221 Setting conflict Indicates that a legal program data element was
parsed, but could not be executed due to the current power
supply state.
The following list is not exhaustive but does cover some of the
more common conditions that may contribute to this error:
• OVP/UVP Set Points —The OVP and UVP limit the setting
of the voltage set point so that you cannot accidentally trigger
these alarms by changing the set point outside of their range.
Conversely, setting the OVP set point to be less than the
voltage set point will also trigger this error.
• Changing the Set Point while in APG mode —The user will
be unable to change the set point while APG is being used to
control that parameter: voltage or current.
• Autosequence Programming —Various conflicts can occur
while using Autosequence programming; for example, using
the trigger command while the program is running will result
in this error.
• Calibration mode —When in calibration mode, certain
settings will cause an error.
-222 Data out of range
Indicates that a legal program data element was parsed but could
not be executed because the interpreted value was outside the
legal range as defined by the device (see
IEEE 488.2,
11.5.1.1.5)
-224
Illegal parameter value
Used where the exact value, from a list of possible values, was
expected.
-291 Out of memory
Used when the Autosequence programming buffer is full.
