Product Description - YSI MultiDO 5400 User Manual

Introduction
Thank you for purchasing a YSI 5X00 instrument.Throughout this manual YSI
"5X00" is used globally to refer to YSI 5400, 5500D-01, 5500D-02 and 5500D-04
instruments. YSI 5X00s are fully programmable aquatic control and alarm instru-
ments. A key feature of all 5X00 instruments is the ability to independently operate
four dissolved oxygen (DO) inputs, six auxiliary (Aux) inputs and 8 E-Aux systems.
(E-Aux systems require using an optional IOEM.). This allows control of multiple
water systems from one instrument. Peripheral devices wired to the instrument
respond to user-defined configurations to ensure that stable water conditions are
maintained. The instruments' on-site and remote access capability are suitable for
a variety of applications.
5X00 features:
- four (4) independent DO systems;
- six (6) independent Aux I/O systems - [digital, analog (0-1VDC, 0-5VDC,
4-20mA). In addition four (4) of the six Aux I/O systems can be used as
temperature systems.];
- eight (8) E-Aux input systems. E-Aux systems are used to monitor, control
and alarm inputs wired to an optional IOEM
- eight (8) onboard relays - 240VAC@5AMPs; 110VAC@10AMPs;
- universal AC power with power fail alarm (only available on AC instruments);
- optional DC power with low battery alarm;
- four (4) ten event daily timers;
- four (4) feed timers;
- two (2) 32-bit processors;
- non-volatile memory of sensor, event, calibration, and configuration* data logs;
- 2000 data set memory for sensor data;
- field upgradable software and firmware;
- backlit LCD with timer function - input and output data displayed continu-
ously;
- menu-driven programming with four (4) softkeys;
- networking capability - ability to connect a total of 32 5X00s, 5200As, IOEMs
and REMs on one network via RS485 protocol;
- networked instruments can utilize another instruments output for a local
NEW
system control or alarm;
- IOEM inputs and outputs can be used for a variety of uses - see IOEM/REM
Installation and Safety Guide;
- optional AquaManager® PC software** serves as monitor management tool via
direct (RS232) or TCP/IP connection. (AquaManager is required to configure
IOEM instruments on a network.);

- email alarming via TCP/IP from instrument and/or AquaManager (local or
TCP/IP) connection;
- NEMA 4X, IP65 enclosure;
See Product Specifications - page 13 for complete details on all 5X00 features.
*A configuration log records any changes made to the 5X00 setup. For example,
changing a set point for an alarm would be recorded in the configuration log.
**AquaManager displays near real time data from 5X00 instruments and provides
data logging, graphing, autopolling, mapping, and system configuration control
from a PC. AquaManager is a valuable tool for remote and local access applications.

Product Description

The 5X00 system manages aquatic environments by automating control and alarm
devices to maintain stable water conditions.
A 5X00 system is configured by the user. Therefore, each system setup is unique to
the application. An example of a 5X00 system could include*:
- 5X00 instrument(s);
- 5X00 components such as power, communication, and network devices;
- *input peripheral devices (i.e. float switch, probe assembly);
- *output peripheral devices (i.e. aerator);
- 5X00 user-defined configuration;
- AquaManager PC interface (optional);
*Not all of the above items are included with the purchase of a 5X00 instrument.
Input devices send data to the 5X00. This data is processed based on instrument
configuration. For example, a DO sensor (input) reports a 5.4 mg/L value and
relay #3 (output) is configured to activate an aerator when value is ≤ 5.5 mg/L. The
aerator wired to relay #3 will energize until the 5X00 receives a DO sensor reading
≥ set point value.
Figure 1.1 shows the 5X00 front panel and enclosure. The front panel includes an
LCD which continuously displays enabled current system conditions. Front Panel
Keys are used to navigate screens and program configurations. Compression fittings
located at the bottom of the enclosure provide liquid-tight connections for wiring
peripheral devices and instrument components.
