Initiates a fill valve open. This bit
can be used to initiate a manual fill
cycle or a auto fill cycle if the auto fill
mode is selected. The tank fill valve
will close upon reaching the high
level switch. See Byte 79 for tank
level status. If the Tank fill bit is
maintained the GCA will close the
valve when the tank is full. Auto time
out and alarm if the Hi level is not
reached within a preset time.

Errors requiring acknowledgement
are presented on first in first out
basis. The latest error is currently in
the error register in the CGM. The
PLC must send back the exact
ASCII value for the error to be
acknowledged in the CGM. If an
incorrect ASCII error code is sent
back to the CGM then the error will
not clear and the CGM register will
be overwritten with the incorrect
error. If multiple error codes exists
then the PLC must acknowledge
them in the order the errors are sent
to the PLC from the CGM. See
bytes 80-83 and 84 for errors and
status.
