SubDrive/MonoDrive Connect
System Fault Relay
The SubDrive/MonoDrive is fitted 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/MonoDrive NEMA 3R family of controllers support a 4-20mA analog pressure
transducer input (100 PSI analog transducer is included with the controller). The default
pressure range is 5-95 PSI with an adjustment knob provided to set the desired system
pressure. The drive will display the system pressure (ex. "50P" for 50 PSI) 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/MonoDrive NEMA 3R drive
family. When the system is equipped with a moisture sensor, the drive will stop pumping
and indicate a specific 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
32 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/MonoDrive 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 50 PSI and a cut-in pressure of 30 PSI would allow the drive to regulate system
pressure at 50 PSI when running, but will not turn the drive on until the system pressure
drops below 30 PSI. The FE Connect mobile app is required to activate and set the
7
cut-in pressure.
