Control Switch Operation - Franklin Electric SubDrive Solar Manuel D'installation

2 Control Switch Operation

The SubDrive Solar is designed to utilize up to two control switches for operation. When both
switches are installed, the controller starts to pump and waits to shut off until both switches
read "OPEN". Once it shuts off, the controller then waits to run again until both switches read
"CLOSED". An example application (Figure 10) is to use separate level switches to indicate high
and low water levels. Two pressure switches, one with a high pressure cut-out in the "STOP" input
terminal, and a second low pressure cut-in switch in the "RUN" input terminal can also be used
to manage the system in applications that do not have an open discharge. Parameter 1 should be
changed to "2" in the menu controls. SEE USER DEFINABLE PARAMETERS in operation section of
manual for instructions.
1 Control Switch Operation
Alternatively, the SubDrive Solar controller may be configured to control water level by using
a single input switch. Once properly configured for a single active input with a control switch
installed, the controller starts to pump and waits to shut off until the active switch reads "OPEN".
Once it shuts off, the controller then waits to run again until the switch reads "CLOSED". An
example application (Figure 10) would be to use a single-contact level-switch that keeps the
storage tank as full as possible without overflowing. A single pump control pressure switch can be
used to control the pressure range between an adjustable range (i.e. 30/50 psi pressure switch).
For single level switch control, use only the "RUN" terminal connections. Parameter 1 should be
changed to "1" in the menu controls. SEE USER DEFINABLE PARAMETERS in operation section of
manual for instructions.
0 Control Switch Operation
Lastly, the SubDrive Solar controller may be configured to not use a control switch. The SubDrive
Solar controller defaults to parameter 1 setting of 0 control switch inputs. In this configuration
the SubDrive Solar will always try to run the motor and pump water as long as there is sufficient
power from the solar array or alternate AC power source.
