2.25 Optional Inductive Probe Wiring
The optional Inductive Conductivity Probe includes a
separate Inductive Interface Board and the probe with
4-conductor cable to power the probe and communicate
the tank temperature and conductivity readings to the
dispenser. To install the optional Inductive Conductivity
Probe, follow these steps:
Important: Install the Inductive Conductivity Probe into the
wash tank before proceeding per diagram.
1) Disconnect power to unit before opening the front cover.
2) Open the front cover: remove the dust cover and loosen
the screw on the right front of the dispenser
3) Route the end of the 4-conductor cable from the
inductive probe through the conduit fitting in the bottom
of the unit
4) On the Inductive Interface Board, insert each wire Red,
Black, Brown and Orange into the green connector
and tighten each set screw per the pinout:
Pin 1 = RedRed - Power +
Pin 2 = BlackBlack - Power -
Pin 3 = BrownBrown - Serial Rx
Pin 4 = OrangeOrange - Serial Tx
5) Insert the Inductive Interface Board black connector into
the Main Board black connector – Refer to Main Board
Connections in Section 2.22 on page 14.
6) Close the front cover, secure with the screw, and replace
the dust cover.
7) Restore power.
8) In the Hydro Connect App ensure the unit is set to Probe
mode. See Section 5.02 on page 25.
2.26 Optional Rinse Temperature Sensor Kit
The optional rinse temperature sensor communicates
the rinse temperature readings back to the dispenser.
Dispensers that come with this option will be pre-wired to
the Main Board with a 2-conductor cable with Red and
Black wires. (See Main Board Connections on page 14).
RedRed - Rinse Temperature Sensor
BlackBlack - Rinse Temperature Sensor
To install the optional rinse temperature sensor kit, follow
these steps:
1) Disconnect all power to the unit before making any
connections.
2) Install the rinse temperature sensor per the dish machine
manufacturer’s instructions, or refer to section 2.17 on
page 13.
3) Route the senor wires to the temperature sensor wires
coming from the dish machine and cut to fit if needed.
4) Crimp the two smaller spade connectors included in the
kit to the two temperature sensor black wires and the
two larger spade connectors to the red and black wires
of the 2-conductor cable.
5) Plug in the mating spade connectors to connect the red
and black wires on the 2-conductor cable to the spade
terminals on the temperature sensor (polarity is not
important). Ensure that connections are tight and secure.
6) Restore power.
WARNING: Electrical installation should be
completed by a qualified electrician. All local and
national electrical regulations are to be observed.
