Invert ON/OFF:

Switches the logical sense of the contact set so you can control on contacts opening or

closing.

Applications: Allows a control only when relay changes state

Surge tank fill, remote disable, second flow switch

ON when contact is closed or ON for 50% of the pump

frequency period. Mirrors the time that the electronic contact set

pulsing the pump is closed. Example: A pump running at 10

SPM would have it’s indicating LED on for 3 Seconds and OFF

3 Seconds since 10 Strokes/Minute is a 6 second period & 5.5%

of rated for a 180SPM rated pump.
