P.35
NOTE
Do not wire vacant pins.
NOTE
Apply a 24V DC power for input signals on the pump side. Do not apply this voltage on
the equipment side.
NOTE
Conditions of output contact depend on those signals. Apply suitable voltage for each
contact; relay or open collector outputs.
NOTE
Be sure to wire all signals with the correct polarity (+/-).
NOTE
When output signals are used to energize an inductive load such as a relay, be sure to
insert a diode (100V / 1A class) in order to absorb the back electromotive force due to
surge current.
