6.2 Auto/Manual Mode
Auto/Manual Mode allows the operators to switch between Auto and Manual pump control in the field,
without needing to change the PF1 configuration each time. Typically, a Double Pole Double Throw
Relay (DPDT) is installed as shown in the diagram below.

NOTE
Manual mode will not work properly unless there is a valid iSet value, as
it relies on correct operation of the pump algorithm.
Without a valid iSet value, Auto / Manual mode will only run for 30
seconds, before stopping
– failsafe.
6.3 Pump Float Switch
If Pump Protection is enabled and the Sleep period set to
“Off”, it is possible to control the PF1 pump
function by means of a float switch. The float system is simply a high and low water level float switch,
which is interfaced with the local Start and Stop inputs of the PF1. An external stop button, on the face of
the starter panel, would be included.
