QUICKSTART GUIDE
Electrical Installation

Control Circuit Connections
NOTE:
All control terminals accept wire sizes from 12 to 26 AWG and should be tightened to a torque of 3
in-lbs (0.35 Nm) maximum.
1.
Pressure Transducer
– When using a pressure transducer:
•
Connect the red cable lead to the TRAN24 terminal.
•
Connect the black cable lead to the – terminal.
•
Connect the shield wire (when applicable) to the S terminal.
NOTE:
A 200 psi transducer is required by default.
2.
Pressure Sensor
– When using a standard pressure sensor:
•
Connect the sensor leads (interchangeable) to the Pressure Sensor terminals.
3.
Hand/Auto Switch
– Connect a dry contact switch to this terminal to select Hand or Auto modes.
The drive will regulate pressure in auto mode when this terminal is open. The drive will run at a fixed
frequency with this terminal is closed. The frequency can be selected via the up/down buttons.
4.
Run/Stop Switch
– The drive will operate regularly when this terminal is open. The drive will stop
the motor if this terminal is closed.
NOTE:
When Stop is selected, the drive motor will stop even if the drive is in Auto mode.
5.
PT100/1000
– Connector for external RTD temperature sensor.
•
I+ Positive connection for excitation current circuit for two, three, and four wire PT100/PT1000 RTD
sensors.
•
V+ Positive connection for voltage sensing circuit for two, three, and four wire PT100/PT1000 RTD
sensors.
•
I-/V- Negative connections for the excitation and voltage sensing circuits for two, three, and four
wire PT100/PT1000 RTD sensors
6.
Moisture Sensor
– The WET SENSOR terminal supports the Franklin Electric Moisture Sensor.
•
Connect the red cable lead to the +24 terminal.
•
Connect the black cable lead to the terminal.
•
Connect the white cable lead to the I+ terminal.
•
Connect the green cable lead to the I– terminal.
7.
Dual Setpoint
– The drive will regulate to Pressure Setpoint 1 when this terminal is open. Pressure
Setpoint 2 is active when this terminal is closed.
8.
4-20mA Out
– The 4-20mA Out allows the user to repeat the incoming Pressure Transducer 4-
20mA signal. Additionally, DIP SW1 Position 4 can be toggled to output a 4-20mA signal of the
motor speed.
9.
MultiDrive
– Connections should be from each terminal to the corresponding terminal on the next
drive(s) in series.
•
Shield wires should be connected together and grounded on one end only.
•
Termination Switch 2 (to the left of the connector) should be in the
Up
(On) position for the first and
last drives in the series.
10.
Modbus
– Terminals –, +, and SG provide RS-485 connections for Modbus communications to an
external computer-based monitoring or control device.
•
Termination Switch 1 (to the left of the connector) should be in the
Up
(On) position for communica
-
tions.
