Introduction
ank you for purchasing a YSI 5X00 instrument.roughout 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.). is allows control of multiple
water systems from one instrument. Peripheral devices wired to the instrument
respond to user-dened congurations to ensure that stable water conditions are
maintained. e 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;

Introduction
- email alarming via TCP/IP from instrument and/or AquaManager (local or
TCP/IP) connection;
- NEMA 4X, IP65 enclosure;
See Product Specications - page 13 for complete details on all 5X00 features.
*A conguration log records any changes made to the 5X00 setup. For example,
changing a set point for an alarm would be recorded in the conguration log.
**AquaManager displays near real time data from 5X00 instruments and provides
data logging, graphing, autopolling, mapping, and system conguration control
from a PC. AquaManager is a valuable tool for remote and local access applications.
Product Description
e 5X00 system manages aquatic environments by automating control and alarm
devices to maintain stable water conditions.
A 5X00 system is congured by the user. erefore, 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. oat switch, probe assembly);
- *output peripheral devices (i.e. aerator);
- 5X00 user-dened conguration;
- 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. is data is processed based on instrument
conguration. For example, a DO sensor (input) reports a 5.4 mg/L value and
relay #3 (output) is congured to activate an aerator when value is ≤5.5 mg/L. e
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. e front panel includes an
LCD which continuously displays enabled current system conditions. Front Panel
Keys are used to navigate screens and program congurations. Compression ttings
located at the bottom of the enclosure provide liquid-tight connections for wiring
peripheral devices and instrument components.

Step 2 Locate and Install Sensor(s)
roughout the manual, the term “probe” refers to the end of the cable where the
sensor is located and the term “sensor” refers to the sensing portion of the cable/
probe assembly.
DO Sensors
5X00 instruments can be congured with 1, 2, 3, or 4 dissolved oxygen (DO) sensors
depending on the model. (models 5400 and 5500D-04 can be congured with up to
4 DO probes; model 5500D-02 can be congured with up to 2 DO probes; model
5500D-01 can be congugured with 1 DO probe.) Auxiliary (aux) inputs 3, 4, 5 and/
or 6 can be congured as temperature inputs. YSI 5400 instruments use a YSI 5421-X
DO (galvanic)/temperature, and/or a YSI 5420-X DO (galvanic) sensor assembly.
YSI 5500 instruments use YSI 626250 ODO (Optical Dissolved Oxygen) sensors.
DO sensors for 5400 instruments require a properly installed membrane. e 5420
and 5421 galvanic sensors use a 2 mil Teon membrane. ODO sensors for 5500 in-
struments require a sensing cap. 5500 instrument sensor caps are factory calibrated
with sensor cap coecients. It is important to retain sensor cap coecients (provided
by YSI) for the life of the sensor.
Temperature Sensors
Temperature sensor(s) must use a 10K thermistor (at 25C). See Appendix 6 Alpha
A Curve - page 256.
Aux temperature sensors can be congured as the temperature source for DO sys-
tems on YSI 5400 instruments. Aux temperature sensor(s) cannot be congured as
DO temperature sources on YSI 5500 instruments. YSI 5500 DO systems always
use the temperature from the YSI ODO probe. For accurate DO measurements,
ensure that the temperature reading for each DO channel is representative of the
temperature at that DO sensor’s location. is is important when using the same
temperature input source for multiple DO sensors. Example - if the temperature
source for DO1 and DO2 is the temperature sensor connected to Aux 3 at the DO1
sensor location, it is important that the temperature at the DO2 sensor location is
the same as at DO1 sensor location.
See Chapter 4 Sensor Setup - page 150, for information on conguring 5X00 sen-
sor systems. User dened DO system conguration items include:
- Display format (i.e. units of measure. For example, mg/L or % saturation,
°C or °F);
- Temperature source (5400 only);
5400
- Salinity input value (user entered salinity value of the water being monitored);
- Elevation;
- Setpoint, control, and alarm values and ranges;
- Control and alarm relay assignments;
Location Considerations
Readings gathered at the sensor location(s) are data logged and processed by the
5X00 instrument. Output control and alarm devices are congured to respond to
sensor values. erefore, it is essential to have accurate readings at the sensor loca-
tion. Locate sensors according to the below specications.
Locate sensor end of probe assembly:
•in a location that represents the entire system
•where the water ow is at least 6 inches per second (15.24 cm/sec) for 2.0
mil Teon membrane
•in a location that is free from debris (e.g. algae); ideally at a 45˚ angle from
vertical position and directed with the ow - gure 3.10
Figure 3.10
•in a well mixed, free-owing area; midstream and mid-depth typically gives
representative readings; the probe assembly and cable are fully submersible
up to the cable connector
•submersed at all times so liquid level uctuations do not expose the sensors
to the atmosphere
•so the sensor/probe cabling is not routed near rotating machinery and/or
equipment involving electrical switching or regulation
•so that the sensor assembly and cabling are located away from sources of
electrical interference such as UV sterilizers, orescent lighting, ballasts,
pumps, any high voltage peripheral devices, etc.

•where regular maintenance, including calibration can easily be done. Cali-
brations are performed using the 5X00 front panel.
Note:
- If a 5420 or 5421 sensor requires replacement, the entire probe/cable assembly
must to be replaced.
Locate sensor end of probe assembly:
•in a location that represents the entire system
•Insert the probe into sample. Move the probe in the sample to release any
air bubbles and to provide a fresh sample to the sensor cap. is movement
is only necessary when rst inserting the probe into the sample.
•Since the ProODO utilizes optical luminescent technology, continuous
sample movement or stirring is not required. (Please note however that ow
does increase response time of sensor.) e probe will t into a 300 mL BOD
bottle for taking initial and nal BOD readings. For best results in a BOD
bottle, a stirring device should be used to properly mix the sample and to
keep solids from settling at the bottom.
•Allow the temperature readings to stabilize and wait approximately 25-35
seconds for the DO readings to stabilize.
•in a location that is free from debris (e.g. algae); ideally at a 45˚ angle from
vertical position and directed with the ow.
•in a well mixed, free-owing area; midstream and mid-depth typically gives

Directions to prepare the ODO probe for the rst time:
1. Remove the metal probe guard from the probe by turning it counterclock-
wise.
2. Remove the red storage cap which contains a moist sponge from the end of
the probe by pulling it straight o the sensor. Save this to use later for long
term storage.
3. Reinstall the probe guard by sliding it carefully over the sensor and then
threading it onto the cable/probe assembly with a clock.
4. Calibrate probe - page 83.
Notes:
- A new cable/probe assembly already has a sensor cap installed and the sensor
cap coecients are preloaded into the probe at the factory.
- Perform ODO calibration whenever ODO caps are replaced see Calibration
page 83.
Install Temperature Sensors
e 5X00 system will support 4 Temperature/Aux Analog inputs. Temperature
sensors are included on YSI 5421 (galvanic) and 626250 sensor and/or sensor as-
semblies. Alternate temperature sensors can be used but must be thermistors with
10K at 25C . See Appendix 6 Alpha Curve - page 256.
Aer installing the temperature sensor in its monitoring location, see Wire Tem-
perature Sensors - page 52.
Probes should be serviced on a regular basis. See Probe Maintenance - page 211.
Wiring Information
System components must be wired correctly to ensure reliable performance and
accurate data collection. Directions are provided on the following pages for wiring
all components and peripheral devices.
PCBs
ere are four printed circuit boards (PCBs) inside the 5X00 enclosure. ey are:
- Display board (mounted in the front panel)
- I/O board is attached to a metal plate inside the enclosure and is visible when
front panel is removed
- DO daughter board mounted to the I/O Board
- Control board (connected to the under side of the I/O Board)
Notes:
- I/O board and control board (including DO daughter board) are attached to
a metal plate and are referred to as the “lower board assembly”. See Control
Board - page 42.
- No 5X00 components or peripheral devices are wired to the display or DO
daughter board.
Most components including: power, Aux input, network, relay output, and RS232
communication components are terminated on the I/O board. 5X00 ground wire
and sensor ground wires (also called drain wires) are terminated to the metal plate
that is attached to the lower board assembly. e optional serial to ethernet device is
installed on the control board. e front panel must be removed when wiring 5X00
components and peripheral devices. See Accessing the I/O Board - page 40. It is
recommended that some system conguration and testing be done in conjunction
with hardware installation. is will ensure that the 5X00 system is wired correctly.
Necessary conguration information (from Chapter 4 - “Conguration”) is referenced
in the applicable test system procedure.
WARNING: Follow all safety information and local electrical codes when wiring
5X00 system components and peripheral devices. Proper wire gauge should be
determined based on voltages and wire/cable length. Incorrect wiring can result
in damage to you or equipment. Ground loops can also result due to improper
wiring.
