Control Circuit Connections
Control Wire routing
– Route pressure transducer or sensor wiring through the smaller opening on the bot
-
tom of the drive to the right of the input power wires. Seal with strain relief grommet. Tighten seal nut to
25-30 in-lbs (2.8-3.4 Nm) and locking nut to 15-20 in-lbs (1.7-2.2 Nm).
NOTE:
All control terminals accept wire sizes from 12 to 26 AWG and should be tightened to a torque of 5 in-
lbs (0.6 Nm) maximum.

Pressure Sensor
– When using a standard pressure sensor, locate the terminal labeled PRESSURE
SENSOR (PS).
•
Connect the sensor leads (interchangeable) to the PS terminals.
Note:
A 10-foot (3 m) section of sensor cable is provided. It is possible to use similar 22 AWG low
capacitance wire for distances up to 100 feet (30 m). Longer cable lengths should not be used and can
cause the drive to operate incorrectly. Refer to
2.
Pressure Transducer
– When using a pressure transducer, locate the terminal block labeled TRANS
-
DUCER (XDCR).
•
Connect the red cable lead to the +24 terminal.
•
Connect the black cable lead to the – terminal.
•
Connect the shield wire (when applicable) to the S terminal.
