SubDrive Connect
11
System Fault Relay
The SubDrive is tted with a relay output that activates (normally-open contact will close)
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). It is not recommended to use
this function relay to control critical systems (chemical dosing, etc.).
Analog Pressure Transducer
The SubDrive Connect IP 23 family of controllers support a 4-20mA analog pressure
transducer input (10 bar analog transducer is included with the controller). The default
pressure range is 0.5 - 9.5 bar with an adjustment knob provided to set the desired system
pressure. The drive will display the system pressure (ex. 5.5 b for 5.5 bar) when using an
analog pressure transducer rather than motor speed when using the traditional SubDrive
pressure sensor. Additional pressure transducer ranges are supported by using the FE
Connect mobile app.
Moisture / Wet Floor Sensor
An additional input to support an optional Franklin Electric Moisture Sensor (often referred to
as a Wet Floor Sensor ) has been added to the SubDrive Connect IP 23 drive family. When
the system is equipped with a moisture sensor, the drive will stop pumping and indicate a
speci c fault code when the sensor detects the presence of water. This does not replace the
need for a pressure relief valve in the system. Refer to the Accessories page for ordering
information.
Wi-Fi and FE Connect Mobile App
Wi-Fi connectivity is included in the drive to enable a connection to be made between the
drive and a single Wi-Fi capable device (smartphone, tablet, etc.). This connection can
be used in order to adjust advanced settings, monitor drive characteristics, and view fault
history when using the FE Connect mobile app. See the Advanced Set-up section on page
35 of this manual for more details regarding the capabilities of the Wi-Fi connection.
Auxiliary Control Input (App Only)
A 24 VDC dry-contact, digital control input labeled Aux In is provided to allow for additional
external control of the SubDrive controller. This input can be set using the FE Connect
mobile app to control the drive in the following ways: fault when high, fault when low.
Drawdown (App Only)
When using an analog pressure transducer in the system, an optional cut-in pressure
can be set to allow for pressure drawdown in the system. For example, a system set point
pressure of 5 bar and a cut-in pressure of 2 bar would allow the drive to regulate system
pressure at 5 bar when running, but will not turn the drive on until the system pressure drops
below 2 bar. The FE Connect mobile app is required to activate and set the cut-in pressure.
