CAUTION
Do not wire vacant pins.
CAUTION
Apply a 12V DC power for input signals on the pump side. Do not apply this
voltage on the equipment side.
The output signals are generated from an open collector output. Apply a voltage not
exceeding 50V DC on the equipment side.
CAUTION
Be sure to wire all signals with the correct polarity (SIG./COM.)
CAUTION
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 currents.
