NOTE
The following points must be considered when the float arrangement is
used. The PF1 Start input must be cycled for each start; it is an edge
sensitive input. The PF1 Stop input is level sensitive. So long as the
Stop input is open, the pump will remain in the stopped state,
regardless of the Start input state.
6.4 Pump Resume after Power Failure
If Pump Protection is enabled, it is possible to configure the PF1 to re-close the outlet after system
power is restored from an outage. This is
called the “Resume after Power Failure” function and it is
independent of the Pump Sleep Mode.
If auxiliary power is lost to the system while the pump outlet is running, when the power supply is
restored, the PF1 will close the outlet and allow pumping to resume. This function will only operate if all
PF1 enabled tripping functions are healthy (e.g. EL and EC).
In order to enable this feature of the PF1, ensure that the relay is in Pump Control Mode and use the
Smart Tools software to toggle the
“Pump Resume after Power Failure”
setting to “Yes”.
WARNING!
If the PF1 is set to resume after a power failure, the pump can and will
energise after a power outage. All operators should be aware of this.
This setting should be used with caution.
6.5 Pump Remote Start and Stop
In order to use the remote start and stop feature of the PF1, the Earth Continuity (EC) protection setting
must be enabled using the supplied Smart Tools software. Once the EC protection has been enabled,
then the remote start feature can be enabled.
For information on the setup and operation of the PF1
’s remote start and stop features, refer to Section
