ESSAGES
•
-303,”Input overflow”
The four input buffers are all occupied with unprocessed commands or
queries. The command or query is lost. Review the handshaking on
page 141 for directions for avoiding input overflow errors.
•
-304,”Error buffer overflow”
More than 10 errors have occurred. For further errors to be recorded in
the internal buffer, at least one error must be cleared.
•
-305,”Supply is off”
A command was attempted while the “Turn on power supply/Press
ENTER to continue” banner is displayed. Commands are disallowed
until the banner has been acknowledged.
•
-306,”Rampdown is active”
No commands are allowed during an active rampdown. All user input is
blocked until the rampdown process completes.
•
-307,”Cooled switch @ 0A required”
A persistent switch current auto-detect cycle requires an initially cooled
switch at zero current before initiation.
•
-308,”N/A when persistent”
Attempted to execute a function that is not available if the magnet is
presently in persistent mode.

•
-401,”Checksum failed”
The non-volatile memory which stores the calibration data for the Model
430 Programmer is corrupted. Contact an Authorized AMI Technical
Representative for further instructions. Do not continue to use the Model
430 Programmer to operate a superconducting magnet.
•
-402,”Serial framing error”
The baud rate of the Model 430 Programmer and host device are not
identical. The host device must be set to the same baud rate as the
Model 430 Programmer (115200).
•
-403,”Serial parity error”
The number of data bits and/or the parity of the Model 430 Programmer
and the host device are not identical. The host device must be set for the
