SubDrive/MonoDrive Connect
Duplex Alternator Built-In (App Only)
The capability of the SubDrive Duplex Alternator product has now been built into the
SubDrive/MonoDrive NEMA 3R product family. A communication cable connected between
two (2) drives and the FE Connect mobile app are required to activate this feature.
Adjustable Underload Off Time (App Only)
The Underload Off Time determines how long the drive will wait before attempting to run
following an Underload event. The default time is 5 minutes, but is user-adjustable through
the Wi-Fi interface from 1 minute to 48 hours.
System Diagnostics Fault History (App Only)
In addition to regulating pump pressure and accurately controlling motor operation,
the SubDrive/MonoDrive continuously monitors system performance and can detect a
variety of abnormal conditions. In many cases, the controller will compensate as needed
to maintain continuous system operation; however, if there is a high risk of equipment
damage, the controller will protect the system and display the fault condition. If possible,
the controller will try to restart itself when the fault condition subsides. Each time a fault is
detected in the system, the drive records the fault and the the actual date and time when
the fault was detected. A maximum of 500 events are recorded and can be viewed and
emailed using the FE Connect mobile app.
Adjustable Bump Modes (App Only)
Using the Advanced Setup (Wi-Fi and FE Connect App), the bump mode and tank size
settings of the drive can be changed. Bump mode controls how hard the drive will pump for
the very short time period just before attempting to shut down. The drive ships with default
settings that are compatible with the majority of SubDrive applications. For applications
with large pressure tanks or trouble shutting down, the bump mode can be modified to be
more aggressive. The system behavior should be monitored when adjusting these settings
to ensure proper operation.
Replaceable Parts
Cooling Fan
In the event that the cooling fan fails and results in an occurrence of frequent Overheated
Drive faults (Fault Code F7), the fan is able to be replaced. See Accessories section for
information regarding NEMA 3R Fan Replacement kits.
Enhanced Pressure Input Board
In the event that a lightning strike creates a surge on the various I/O terminals of the drive,
the Enhanced Pressure Input Board (EPIB) can become damaged causing the drive to not
operate. Rather than replacing the entire drive, the EPIB can be replaced in an attempt
to repair the drive. See the Accessories section for information regarding the Enhanced
Pressure Sensor Input Board Replacement kit.
