6.2.9. Minimum control wiring requirements when using an irradiance sensor
The P2 Solar Pump Drive is a very flexible product which can be controlled in a number of ways. In order to operate the drive as
detailed in section
, the drive will need the STO circuit to be closed (see section
and a drive enable provided to Digital Input 1 as shown below. Please note that if the STO function is not going to be used in the
application, the wiring is still required and a link will be needed between terminals T1-T12 and T9-T13.

The STO inputs can be used as a high integrity means of preventing torque
being applied on the motor – section
. If this function
is not required, the terminals must be linked as illustrated.
6.2.10. Operation with a Float-switch
Some applications require the start/stop of the pump to be controlled by a float switch. In some instances, waves on the water surface
can cause unwanted start/stop commands to the drive. To overcome the potential issue caused by these waves, a mode has been
created in the drive where a delay can be applied to the start and to the stop command. This can be configured as shown below:

For use with a float switch, set this parameter to the required value:
15: Float switch with normally open contact (close to run)
16: Float switch with normally closed contact (open to run)
The delay start and delay stop are configured in P6-06 and P6-07.
P6-06
Delay Start Time

This delay will be applied to all RUN commands for the drive.
P6-07
Low Power Standby Restart delay
