Overview - Pentair POINT FOUR RIU3 Guía De Instalación Y Del Usuario

This manual is designed as a guide to assist users in becoming familiar with the various functions of the RIU3 (remote
interface unit). Each section of this manual is set up to easily guide users through all stages of installation, setup and
maintenance. Starting from unpacking and inspecting the box, this manual will explain all parts and functions of the
system to allow users to get the most out of the RIU3 for all their system monitoring needs.
The PT4 RIU3 is a field mounted single sensor transmitter/controller. The unit is compatible with a variety of water quality
probes such as dissolved oxygen, temperature and pH. For a full list of compatible probes, see Table1. The RIU3 is
equipped with a large font 8 x 2 backlit display so the user can view the sensor readings. The unit contains two SPDT
10amp relays to be used for alarm and/or control outputs. The control blocks can be configured as described on page
17. Probe calibration can also be done via the RIU3 interface as described on page 19.
The RIU3 uses IP67-rated cable glands for the power, data and probe connections, sealing the unit for wet environments.
Although the RIU will function as a standalone controller, up to 99 units may be daisy chained for a network connection.
This allows the user to collect, manipulate and control all of the data via the PT4 LC Controller or using the PT4 Sync
HMI Software (Windows Based).
