Description
Is activated when the transducer signal is below 3 mA.
When lifted, this float switch activates the alarm indication on the screen and the audible
alarm.
When lowered, this float switch stops the pump and activates the indication on the
screen.
Is activated when pump 1 overtemperature sensor, seal failure sensor or overload relay
has tripped.
Is activated when pump 2 overtemperature sensor, seal failure sensor or overload relay
has tripped.
