Overload Response in Message Mode
When an overload detector is in message mode, the respective overload LED will follow the
overload status flag, unless it is disabled by the command:
OVLLED N<cr>
.
The
Overload
LED will light under overload condition; it will turn off approximately one second
after the condition has been removed. For the conditioning amplifier, the time can be shortened
by the command:
OLVTM M<cr>
.
When the overload state changes, the message sent will be:
OVL_on<crlf>
or
OVL_off<crlf>
or
SOVL_on<crlf>
or
SOVL_off<crlf>
or
COVL_on<crlf>
or
COVL_off<crlf>
or
MOVL_on<crlf>
or
MOVL_off<crlf>
.
If an overload occurs while a command is sent to the 12AU, the overload status will not be read
and no response sent back until the command has been processed.
Restart and Default
Restart<cr>
Restarts 12AU.
Factory_default<cr>
