Blue Tank Auto/Manual Fill Request
Blue Tank Auto/Manual Fill Request is a bit used to
request a fill command to the tank. While the tank is in
auto/manual fill mode, set this bit to 1 to start the filling
process. To cancel the filling process at any time, set
this bit to 0. Once the tank is done refilling, set this bit to
0 for the next fill request command.
Recirculation Request
Recirculation Request is a bit used to turn the
recirculation feature on and off, depending on the
recirculation mode. When the PLC is ready to begin
recirculation, set this bit to 1. When the PLC is ready to
stop recirculation, set this bit to 0. Recirculation mode
can be found using the Data Exchange, Recirculation
Mode element. See
Recirculation Mode on page 35 for
further explanation of the Recirculation Request bit
interface for each recirculation mode.
NOTE: If a PLC is integrated with the EFR, it is highly
recommended that the recirculation mode is set to
manual, and the PLC is set to control the logic when the
EFR is placed in and out of recirculation through the
Recirculation Request bit.
Desired Active Sequence
Desired Active Sequence is a byte used to request a
new active sequence. If the value supplied is within the
operable range, the value will be accepted by the EFR
and reflected back to the Current Active Sequence of
the Automation Inputs. The operable range of this byte
corresponds to the number of sequences the EFR can
hold, which is 1 to 50.
Acknowledging the Active Error Number
See Appendix D - Error Number Requiring
Acknowledgment on page 38.
Desired Operator Mode Dispense Flow
Rate
Desired Operator Mode Dispense Flow Rate is a byte
used to request a new operator mode dispense flow rate
to the EFR. If the value supplied is within the operable
range and the EFR is running in operator mode, the
value will be accepted by the EFR and reflected back to
the Active Operator Mode Dispense Flow Rate of the
Automation Inputs.
