Control Circuit Connections
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.
1. Control Wire routing – Route pressure transducer or sensor wiring through the smaller opening on the
bottom 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).
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.
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
3. Pressure Sensor – When using a standard pressure sensor, locate the terminal labeled PRESSURE
SENSOR (PS).
• Connect the sensor leads (interchangeable) to the PS terminals.
4. System Alarm Relay – The drive includes a relay output that activates whenever the system is faulted.
Both normally-open (NO) and normally-closed (NC) contacts are provided. The contacts are rated 5 A
at 250 VAC/30 VDC for general purpose loads, or 2A at 250 VAC/30 VDC for inductive loads (i.e. relay).
• This relay is not recommended to control critical systems (chemical dosing, etc.).
5. System Run Relay – The drive includes a relay output that activates whenever the system is actively
pumping. Both normally-open (NO) and normally-closed (NC) contacts are provided. The contacts are
rated 5 A at 250 VAC/30 VDC for general purpose loads, or 2A at 250 VAC/30 VDC for inductive loads
(i.e. relay).
• This relay is not recommended to control critical systems (chemical dosing, etc.).
6. Auxiliary Control Input – A 24 VDC dry-contact, digital control input labeled "Aux In" is provided to
allow for external control of the drive. Connections to this input depend on the application and type of
control.
• Refer to "Drive Control Using an External Device (Auxiliary Input)" on page 37
