Remote Setpoint Selection of one of two preset setpoint values (Optional)
A programmable feature allows for the setpoint value to be toggled between two
preselected values when a dry contact closure is sensed between terminals 8 and 5. For
more information see section 3 (page 21).
FIGURE 2-12
Remote Digital Communications RS 485 Terminals 7 & 8 (Optional)
If the communications network continues on to other units, connect the shields together, but
not to the instrument. A terminating resistor should be installed at the terminals of the last
instrument in the loop. The shield should be grounded at the computer or the
convertor box, if used. See the Protocol Manual (Form 2878) for more details on the use of
the digital communications option.
