PRODUCT.
Certain components are intended to be removable such as the Atlas
Scientific, LLC EZO module and the ITS WF-IB voltage isolator. Exercise
caution when inserting and removing these devices from the board
sockets. Integrated Treatment Systems, LLC does not warrant devices
manufactured by others, nor the WaterFeature8 board, against failure
due to excessive insertion or removal stress.
WARNING:
Exercise caution hen handling sensitive electronics. Electrostatic
Discharge (ESD) may damage EZO circuits and/or the WaterFeature8 board.
Take suitable ESD protective measures henever orking ith these
devices. This may include using ESD mats, grounded rist straps, and
other industry standard ESD precautions. Damage caused by ESD failure
ill void the WaterFeature8
arranty.

1. Atlas Scientific, LLC 8:1 Serial Expander P/N COM-102
Generations 1 and 2 of the WaterFeature8 system use the
Atlas Scientific, LLC erial Expander to automatically identify
and manage sequencing and polling of all inserted EZO
circuits. The WaterFeature8 is shipped with this circuit pre-
installed. Generation 3 systems do not utilize this part.
2. Po er On/Off S itch
Use this switch to manually power the board on and off
before/after connecting/disconnecting power, sensor, or
current loop wiring. ensor Interface ystems are shipped
with this switch in the ON position.
3. +24VDC/GND Input Po er and +5VDC Output Po er
Terminals
Power the board with a +12VDC to +24VDC nominal power
source (+24VDC preferred for best analog output
performance). Maximum power consumption is up to
5.75W when each EZO socket is populated with
Electroconductivity EZO circuits (this is a maximum potential
power consumption scenario), not including extra 5VDC
loads that might be powered from the output terminal. The
analog output circuits may not have enough power to
transmit over long wire runs if the system in powered with
+12VDC, and it is strongly recommended to power the
system with a standard +24VDC power source. The power
adapter provided with the ensor Interface ystem is
properly sized for the devices.
4. Input Sensor Terminals
Connect sensor signal and ground wires at these terminals.
Alternatively, connect sensor wiring to external terminal
strip and wire to the WaterFeature8 accordingly. The ensor
Interface ystem is shipped with BNC or MA connectors for
connecting sensors outside of the enclosure. Note:
powered sensors such as flow meters may require a
separate power supply.
5. Atlas Scientific, LLC EZO Chip Sockets
Insert Atlas Scientific, LLC EZO circuits (and/or ITS WF-IB voltage
isolators) in these locations. Take care to correctly orient
the parts by lining up the pin labels on the EZO with the
silkscreen socket labels printed on the board. WaterFeature8
ystem Builder Kits DO NOT include any EZO circuits; they
must be purchased separately and installed by the user.
WaterFeature8 ensor Interface ystems may include pre-
installed EZO circuits; review with your distributor/vendor
prior to purchasing.
6. HMI Button Pins
The WaterFeature8 A- eries ystem Builder Kit is shipped with
four buttons wired to a common connector with
approximately 10” of wire. The connector is polarized to fit
one way with the onboard pushbutton header. If you need
to make your own button wiring harness use amtec P/N
IPD1-04-D-L connector and amtec CC79R-2024-01-L crimp
pins. The WaterFeature8 ensor Interface ystem uses
Amphenol 75869-332LF headers with 71600-008LF 8-pos.
ribbon cable connectors.
7. LCD HMI Socket
The WaterFeature8 A- eries ystem Builder Kit is shipped with
an LCD screen and approximately 9” ribbon cable. The
ribbon cable plug is designed to fit one way into the board
header and LCD module. Make your own LCD ribbon cable
using 18 conductor 3M HF365/18 F ribbon cable with
Amphenol 71600-018LF (18-pin) IDC connector and strain
relief on one end and Amphenol 71600-020LF (20-pin) IDC
connector and strain relief on the opposite end.
