NOTE: All control terminals accept wire sizes from 12 to 26 AWG and should be tight-
ened to a torque of 3 in-lbs (0.35 Nm) maximum. Do not use power tools to tighten
these screws. All terminals are 24V or less. Control wiring should be copper wire,
75 °C or higher.
Pressure Transducer – When using a pressure transducer:
1.
•
Connect the red cable lead to the TRANSDUCER +24 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 included with the drive.
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. In Auto mode (this terminal is open), the drive will reg-
ulate pressure. In Hand mode (terminal is closed), the drive will run at a fixed
frequency. The frequency can be selected via the up/down buttons.
4. Run/Stop Switch – Connect a dry contact switch to this terminal to select
Run or Stop modes. By default, the drive will operate regularly when this ter-
minal is open. The drive will stop the motor if this terminal is closed. Default
setting can be reversed using the menu and buttons or the mobile app.
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. Refer to
•
Connect the red cable lead to the +24 terminal.
•
Connect the black cable lead to the
•
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 ter-
minal is open. Pressure Setpoint 2 is active when this terminal is closed.
8. Analog (4-20mA) Output – The 4-20mA Analog Output 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.
NOTE: This output is capable of supplying a circuit with a load resistance up
to 900 ohms.
9. MultiDrive – Setup in the mobile app only. 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.
•
DIP Switch SW7 - Position 2 (to the left of the connector) should be in the Up (On)
position for the first and last drives in the series.
10. Digital Input – This feature will be used in the future.
