mode simply by turning them OFF for 1 minute minimum, then back ON.
However, for unattended situations (e.g. truck stops), the pumps must not
be left able to work in the 'stand-alone' mode in case of a controller failure.
Therefore, digit 1 should always be set to one for unattended operation.
For the Bulk Meter Register configuration, when digit 1 is zero, the unit will
work in the 'stand-alone' mode. When digit 1 is one, the unit must be
connected to a Compac Central Controller.
