NOTE: All control switch configurations are superseded by the "Flow Switch". If the flow switch
detects low flow it will "OPEN" and override the run signals sent by the control switches to protect
the motor and drive.

Start-Up and Operation

After all appropriate connections have been made, apply power to the controller. A steady green
light in the "Power/DC Polarity" location indicates that the SubDrive Solar controller has either AC
or DC power connected. A red light in the "Power/DC Polarity" location indicates that the positive
and negative connections have been reversed. The seven segment display will power on shortly after
power is applied to the controller. It will flash the current software version of the main controller,
then the software version of the COMM board processor, and finally to the normal operating display.
The display will show an E2 fault on the display if the polarity is reversed.
By default the seven-segment display shows motor frequency during operation. The display can also
show the system power in kW, or a rotating segmented graphic signifying the pump/motor is running.
These different display modes can be cycled through using the up and down soft buttons. While running
on DC power, approximately every 8 minutes the system will shut down for a few seconds and then
restart. This is normal operation and is used to look at the system open circuit voltage to derive a max
power point.
While running on AC generator power, the drive will shut down approximately every 30 minutes for
a few seconds and restart. This is normal operation; the drive is just attempting to find adequate DC
power input. As soon as DC power becomes available, the system will then change over to the array
power. If DC power is not available or is not adequate, the system will continue to run on AC power.
CAUTION
The SubDrive Solar controller's display is protected by a sliding metal shield. After reading the
display, ensure that the shield covers the display. Failure to do so could result in damage and will
result in yellowing of the view pane and can eventually render the display unreadable.
NOTE: For optimal operation results, it is recommended to flush the bore well system until the water
being discharged is clear and free of debris. This will reduce the chances of the flow switch being
clogged by sediment and debris during initial start-up.
