Drive Control Using an External Device (Auxiliary Input)
The Auxiliary Input is used to stop or start the drive output using an external device such as a float switch,
timer, or irrigation controller. This input can be wired using either an internal 24 VDC signal, or an external
24 VDC supply.
Internal 24 VDC from Transducer +24 terminal or Wet Sensor +24 terminal
External 24 VDC Supply
Use the FE Connect Mobile App to control how the drive will react when the AUX INPUT control terminal is
used. Refer to
"Advanced Options" on page
•
Fault with High (default): In this setting, the drive output will stop when the external switch closes.
•
Fault with Low: In this setting, the drive output will stop when the external switch opens.
In both cases, Fault F26 will be displayed on the monitor. When the switch moves to the opposite position, the
drive output will restart after a short delay.
For example: If using the system to maintain water level in a holding tank:
•
Use a float switch that closes when the water reaches the desired level
•
Set the input to Fault with High.
Example two: If using the system to remove water from a tank:
•
Use a float switch that opens when the tank empties.
•
Set the input to Fault with Low.
Example three: If using a timer to start an irrigation system:
•
Set the timer to send a 24 VDC signal when the system should run
•
Set the input to Fault with Low.
