Split Range Capability
See Fig. 2 and 3. Two R7195A Motor positioners can be wired
to operate in series or can be used to split the range. One
R7195A Motor Positioner can be calibrated from 4 mA to 12
mA and the second positioner can be calibrated from 12 mA
to 20 mA. Both positioners can also operate in series with an
operating range of 4-20 mA.
More than one R7195B Motor Positioner can be connected to
a single 135-ohm input potentiometer as shown in Fig. 3. All
W and R motor positioner terminals are connected in parallel
to the potentiometer. Only one motor positioner terminal B is
connected to the input potentiometer. The R7195B Motor
Positioners may be calibrated to operate as split ranges or all
may be set to the same range. Up to five R7195B Positioners
may be connected to the one potentiometer.

Wiring Motor Positioner to Motor Terminals
1. Refer to wiring diagrams and documentation supplied
with the motor to connect the motor positioner for
specific applications.
2. To avoid inductive interference to the internal circuitry,
separate the leads carrying line voltage from all other
leads.
3. Provide conduit protection for controller leads and
provide separate conduit for motor positioner leads from
terminals 4, 5 and 6.
4. Refer to Fig. 4, 5, 6 and 7 for examples of typical wiring
configurations.
