10. Drainage Mode – Control via Pump Float
Even when using pumps with floats permanently attached, to
achieve maximum pump protection and control, use control floats
or probes wired to the iProtect.
Disable the pump float by tying it in the upward (on) position.
The iProtect monitors current. While supplying power to the pump should the
pump float switch the pump off the current drops to zero. The controller
interprets this as less than the underload response value.
(
Default setting for dry run
protection is 70% of normal run current)
This in turn causes a ‘Dry Run’ error, and the controller will initiate the dry-run recovery time
countdown before attempting to start the pump again. (
Default setting 30 min Parameter 004)
If the installer’s preference is to use the float attached to the pump as the
method of pump control,
terminals 4, 5 and 6 must be bridged
AND the
dry run parameter 009 set to 0%
With the dry run parameter inactive the controller still provides protection against overload,
locked rotor, under voltage and over voltage conditions. Additional benefits to the user are
the anti-seize function, accumulated run time and the last 5 error record.
Connecting an external alarm device
Connection of an external alarm device directly to the iProtect is not currently supported.
11. Drainage Mode – LCD running state images
The controller is receiving a
high level signal. The alarm will
sound.
The pump will run if the
controller is in Auto mode
Related to terminals 10 and 12
There is no water at the source.
The pump will not run.
Related to terminals 4, 5 and 6
There is sufficient water at
the source for the float or
probes to send a run state
signal
The pump starts and runs.
Pump calibration:
(see pg 5)
Switch to manual mode 10 sec.
Start the pump
Allow the pump to reach a stable power.
Press to store. Press to exit.
Ensure the controller is set to
AUTO MODE when finished
