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 open-
ing 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
TRANSDUCER (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
options.
3. Pressure Sensor – When using a standard pressure sensor, locate the terminal labeled PRES-
SURE 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 con-
tacts 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 pro-
vided to allow for external control of the SubDrive/MonoDrive. Connections to this input
depend on the application and type of control.
• Refer to "Drive Control Using an External Device (Auxiliary Input)" on page 41
information.
