A key feature of the YSI 5200 is that it is designed using FLASH memory allowing software updates to
be easily accomplished. Refer to Section 9.1.5 Downloader (Upgrading Software) for instructions on
upgrading the software in the YSI 5200.
Powering the YSI 5200
Primary power for the YSI 5200 is either a wall mount power transformer providing 8.5 to 16 VDC at
700 mA or any power source providing voltage and current in the stated operating range. The YSI 5200
comes standard with a 12VDC 700 mA wall mount power supply. In addition, an optional 12VDC battery
backup input is available for powering the YSI 5200 should the primary power fail.
The YSI 5200 design incorporates FLASH Memory, RAM, and a battery backed-up real-time clock.
Should power be lost, none of the parameter setpoints or configuration data will be lost. However,
during a power failure, data in the data-log will be erased if no backup power is provided to the
unit.
Control Capability
The YSI 5200’s software gives it the capability for parameter control as well as monitoring. Using the 4
built in control relays, a wide variety of monitoring and control features can be automatically activated.
The sensors gather information and relay it to the YSI 5200 controller. The 5200 can directly control
devices through the four built-in relay outputs. Each device that the YSI 5200 controls, such as a heater or
chiller, can be programmed
Timing System
The timing control feature allows the YSI 5200 to control external devices such as a lighting system. The
timing system will support up to 4 independent control times per 24 hours. Each channel has one ON and
OFF time per 24-hour period.
Alarm System
The alarm system provides visual and audible notification in the event that a monitored parameter
exceeds the user defined range. Used in conjunction with the YSI 5201 modem (or a computer running
AquaManager software and equipped with a compatible modem), it provides remote alarm notification

YSI Incorporated 9 5200 Recirculating System Monitor
WARNING: To avoid severe personal injury or damage to the equipment, installation, operation and
Not
service should be performed by qualified personnel who are thoroughly familiar with the entire contents
of this manual.
3.2 Selecting an Installation Location
The 5200 monitor is an on-line continuous measurement tool that can be used to control various
operations and provide valuable insight into the facility’s operation. As with any instrument of this type,
proper installation is the first important step to ensure you are provided with reliable performance and
accurate data. Installation of the monitor and probe should be carefully planned in advance to obtain the
most effective and accurate utilization of the equipment.
3.2.1 Choosing a Probe Location
Probe location is determined by the necessity to obtain water quality readings which are representative of
the bulk flow stream. A suitable location should take a number of physical and chemical factors into
consideration. See Section 3.5 Installing the 5562 or 5561 Probe Assemblies.
Ö Standard probe cable lengths for the 5200 are 4, 10 and 20 meters. Consider the entire distance
required for cable routing when determining cable length requirements and mounting locations.
Ö The probe must be located in the flow stream where the sensors will remain submersed at all
times and level fluctuations will not expose them to the atmosphere.
Ö The probe must be placed in a well mixed, free-flowing area of the process stream. The flow
stream should be representative of the process being monitored/controlled. Placing the probe
midstream and mid-depth typically gives the most reliable results.
Ö Ideally, the probe should be placed at an angle within 45° of vertical and directed with the flow
direction (see Figure 3-1). This location will provide for the least stress on the support arm
holding the probe while minimizing the opportunity to collect debris. Placement against the flow
stream or perpendicular to the flow stream also provides accurate monitoring, but inspection and
cleaning may be required more frequently due to increased collection of debris.

The flow stream should be as free as possible of debris (e.g., algae) which could collect on the probe and
cause erroneous readings. See 3.5 Installing the 5562 or 5561 Probe Assemblies for flow requirements.
YSI Incorporated 10 5200 Recirculating System Monitor
Note that this is an on-line device that is measuring actual conditions in real time. Composite sampling
N
for pH, for example, will not match on-line monitoring. Therefore, pH values recorded by the chart
recorder and/or plant control system connected to the 5200 Monitor cannot be averaged to equal the pH of
a composite sample.
3.2.2 Choosing a Monitor Location
The probe measures conditions in the flow stream and transmits a low voltage signal to the 5200 Monitor.
The probe is attached to a cable that is equipped with a “military grade” watertight connection to the
monitor.
Several options are available for mounting the 5200 Monitor. Easy to use, wall mount brackets (006515
Flange Mounting Kit) are provided with the 5200. If rail or panel mounting is desired, the 6509 Rail
Mount Kit and 6510 Panel Mount Kits are available as accessories.
NOTE: The 5200 Monitor is provided with a weatherproof enclosure that will withstand most
environmental conditions with no compromise to system performance. An optional Weather
Shield (YSI #6505) is available for added protection from the elements. When mounting the 5200
outdoors the 6505 Weather Shield should be used.

Locating the monitor close to the sample location has advantages since accuracy checks and calibration
can be more easily facilitated under this arrangement. For example, a recently calibrated, hand-held
dissolved oxygen meter can be placed next to the 5200’s probe and readings can be compared.
Probe cables for the 5200 Monitor are available in 4 (13.1 ft), 10 (32.8 ft) and 20 (65.6 ft) meter lengths.
The probe cable length determines the maximum distance the monitor can be mounted from the sample
being measured.
Location of the 5200 Monitor should be elevated and in a dry place above the potential flood level. The
unit should be easily accessible for an operator or technician.
Although the monitor is suitable for outdoor use, it should be located in an area where temperature
extremes, vibrations, electromagnetic and radio frequency interference are minimal. Select an installation
location that is at least two (2) feet from any high voltage conduit. Avoid mounting on severely vibrating
YSI Incorporated 11 5200 Recirculating System Monitor
structures or near a high heat source, AC motor or transformer, radio transmitter or antenna. Be sure the
monitor can be fully opened and serviced at its installed location by maintenance personnel.
3.3 Installing the Components
There are three basic parts to installing the YSI 5200 Monitor, which are covered in the following
sections:
Ö Installing the YSI 5200 Monitor hardware and additional components
Ö Installing the probe assembly
Ö Wiring the 5200 Monitor
3.3.1 Sealants, Desiccants and Securing the Monitor
Since the 5200 Monitor will likely be subjected to environmental conditions that promote formation of
condensation, it is very important to follow the instructions below before securing the cover to your
unit(s). This will prevent damage to the electronic components within the Monitor and extend the life of
the monitoring system.
The 5200 Monitor is shipped with three compression fittings. The small compression fitting on the left
side of the bottom panel is to be used for the power supply wire. The two larger compression fitting are
supplied with solid plugs installed. These solid plugs should be left in place if no other electrical
connections are to be made to the 5200.
If electrical connections are required for control relays, PC connections or other devices, there are a
number of options to ensure a watertight installation to the 5200’s case.
1. Solid plugs, located in the 2 larger compression fitting, can be frozen (put in a freezer for 1 hour) and
then easily drilled to the required diameter. The drill bit diameter should be slightly smaller than the
wire diameter so that a watertight seal can be made.
2. Compression plugs with two different pre-sized holes are supplied with the 5200 Monitor. The hole
size in the plugs varies with the amount of torque applied to the compression nut. To install a predrilled plug, the solid plug can be “pushed out” of the compression fitting housing and the pre-drilled
plug installed.
3. Optional conduit fittings (YSI #065926) can be installed in place of the compression fittings. When
using conduit fittings, industrial encapsulant (YSI #065921 conduit sealer) must be used to prevent
moisture from entering the 5200 monitor. After all wiring and connections are complete, apply the
sealant to the conduit openings from the inside of the 5200 Monitor. Failure to use industrial
encapsulant may result in damage to the 5200 Monitor.
Also included with the 5200 Monitor is a desiccant pack, YSI #6506. Desiccant absorbs moisture
captured within the enclosure. After all wiring and connections are complete (just before the cover is to be
installed), place the desiccant pack inside the 5200 enclosure near the bottom right corner. Remove the
desiccant from its protective packet prior to installation.
Secure the monitor’s cover using four mounting screws. Note that the cover contains a captured rubber
gasket that provides weatherproofing. Make certain that the gasket is in place and not twisted or damaged.
Make certain that the large blue ribbon cable is not trapped in the gasket channel before inserting the
screws. When securing the screws, take care not to cross thread. The screws are stainless steel, and the
receiving threads are brass. Do not over-tighten!
CAUTION: Anytime the 5200 cover is removed, replace the desiccant pack with a new pack. Anytime
the 5200 front panel is removed, place it on top of the 5200 Monitor or secure it so that the blue ribbon
cable does not bear the weight of the cover.

Flange Mounting Kit) are provided. If rail or panel mounting is desired, the 6509 Rail Mount Kit and
6510 Panel Mount Kits are available as accessories.
3.4.1 Wall Mounting Option
Although the monitor is designed for outdoor deployment, some operators may prefer the convenience of
reading the monitor under shelter, for example, inside a nearby building. Figure 3-4 shows this indoor
type of installation. Wall-mounting the 5200 Monitor is a simple process using the enclosed 006515
mounting hardware.

3.4.2 Optional 6509 – Rail Mount Kit
The 5200 Monitor can be easily mounted to pipe or handrail (1 to 1½ inch diameter) using the optional
6509 Rail Mount Kit. When using the 6509 Rail Mount Kit, the 006515 mounting flanges will have to be
modified by drilling two holes to accept the u-bolts. The predrilled metal plates can be used as a template.
CAUTION: The monitor should not be mounted on electrical conduit, a hot or vibrating pipe or structure,
or near a high heat source, an AC motor, transformer, radio transmitter or antenna.
3.4.3 Optional 6505 – Weather shield
The Weather Shield provides wall or optional rail mounting capability for the 5200 Monitor.
CAUTION: The monitor should not be mounted on electrical conduit, a hot or vibrating pipe or structure,
or near a high heat source, an AC motor, transformer, radio transmitter or antenna.
YSI Incorporated 15 5200 Recirculating System Monitor
3.4.4 Optional 6510 – Panel Mount Kit
Panel mounting the 5200 Monitor is a simple process using the 6510 Panel Mount hardware and the
following tools; 5/32” Allen wrench, Philips screwdriver, and the necessary tools for cutting the mounting
hole in the control panel. The 5200 Monitor may be mounted in any panel with 9.5”L x 7.5”W space
available, and behind the panel depth of 5.5”.
YSI Incorporated 16 5200 Recirculating System Monitor
3.5 Installing the 5562 or 5561 Probe Assemblies
CAUTION: Keep pH and ORP probe tips IN A MOIST ENVIRONMENT at all times.
After you have chosen suitable sites for the monitor and probe, proceed with the probe installation as
described below.
Avoid routing probe cabling near wiring associated with rotating machinery and/or equipment involving
electrical switching or regulation. In all cases, it is desirable to locate the probes away from sources of
electrical interference such as UV sterilizers, florescent lighting, ballasts, pumps, etc. Consider placing
probe cabling in grounded metallic conduit if unstable readings appear due to electromagnetic
interference.
The 5200 can be configured with either a 5562 multiprobe assembly (DO, Conductivity, Temperature,
and optional pH or pH/ORP sensors) or a 5561 DO/Temp probe assembly.
NOTES: When the 5200’s control functions are to be used, probe placement will be critical to the
operation of the system. Consequently, a professional should be consulted when designing the
system.
Water flow is important to the operation of the DO sensor. In addition, the mixing action provided
by water flow ensures that the area of sampled water is representative of the entire body of water.
Probe installation steps:
1. Select a suitable location for the probe assembly that allows for adequate water flow across the
DO sensor (approximately 0.5 ft/sec).
2. Select a method of securing the probe assembly.
3. Determine a method of routing and securing the cable.
In-Filter Location— A common place for probe location is in the filter. Installing probes in a filter or
sump requires that the probe be secured or hung in an area that will allow for adequate water flow across
the DO sensor (approximately .5 ft/sec).
In-Filter Location Using a Float—A float installation keeps probes at a constant depth, and is
economical to purchase or construct.
To construct a probe float, cut a hole (slightly smaller than the probe diameter) through a small piece of
Styrofoam. Insert the probe into the float so that the entire sensor guard protrudes through the Styrofoam
and the sensors are completely submerged.
In-Tank Location—Installing the probe assembly in a tank requires that the assembly be secured or
hung in an area that will allow for adequate water flow across the DO sensor (approximately 0.5 ft/sec). It
is preferred that the probe be secured so that the cable is not constantly flexed.
If using the 5562, the probe assembly can be secured using the 5205 Probe Mounting Kit or 6511 Probe
Rail Mount Kit. See Section 3.5.2 5205 and 6511 – Optional Probe Mount Kits for 5562 Probes. A
mounting kit is not available for the 5561 probe.
In-Line Location Using a Tee-Fitting—Although in-line probe placement is more time consuming and
requires some extra plumbing, it has been found to be a very effective and safe way to place probes. Inline placement gives accurate readings because water is moving across the probe tips at all times. It also
minimizes biological growth on the sensors.
IMPORTANT NOTE: When maintenance and/or calibration of the sensors is required, the probe
assembly will have to be removed from the in-line fitting. Take this into account when designing the
system. If water flow must be maintained during maintenance, by-pass plumbing will be required.
YSI Incorporated 17 5200 Recirculating System Monitor
For this type of installation, the probe guard is removed and the probe is threaded into a tee-fitting using
the probe guard’s threads. All probes need to be placed into the flow stream. YSI does not provide tee
fittings for this type of installation.
Thread size for 5562 multiparameter probe assembly: 1.50-12 UNF 2A
Thread size for 5561 DO/Temp probe assembly: ¾-27 Class 2 thread
In–Line Location Using A Flow Cell (5562 Probe only) – The 5083 Flow Cell can be connected
anywhere in the pumping system where a water flow rate of 2–3 L/minute can be obtained. Maximum
pressure rating for the 5083 is 25 psi. A portion of water from a pump discharge line can be diverted
through the 5083 Flow Cell, or a method with a designated pump can be utilized.
3.5.2 5205 and 6511 – Optional Probe Mount Kits for 5562 Probes
NOTE: The 6511 kit includes Clamps for Rail Mounting. The 5205 Kit does not include mounting
hardware.

Figure 3-5 Probe Mounting Kit
5205 and 6511 Probe Mount Kits allow a 5562 Probe to be deployed in a permanently mounted two-inch
schedule 40 PVC tube. The schedule 40 PVC is not included in the kit. Once installed, the probe is
deployed by gently sliding it down the tube, where it will rest on a stop cap at the end of the tube. The
sensors and probe guard will protrude through a hole in the stop cap at the end of the tube. See Figure 3-5.
When mounting to a 1–1½″ railing, the 6511 kit should be used. It includes brackets and u-bolts for rail
mounting and a stop cap and adaptor. See Figure 3-5.
When mounting to structures other than 1–1½″ railing, a 5205 kit should be used. When using the 5205
kit, the installer must develop a method of mounting the 2″ PVC tube to a permanent structure. The 5205
kit consists of a stop cap and adapter and does not include mounting hardware.
The 5205 and 6511 Kits should not be mounted on hot or vibrating pipes or structures, or near high heat
sources, AC motors or transformers, radio transmitters or antennas.
CAUTION: Do not mount on electrical conduit.

The following steps should be followed when mounting the 5205 or 6511 Probe Mount Kit.
1. With the 3 setscrews removed from the adapter, slide the adapter over the 5562 Probe. Align the
open screw holes directly over the 3 hex bolts located on the side of the 5562 Probe.
2. Insert the setscrews so that they seat into the head of the probe’s hex bolts.
CAUTION: Do not over-tighten the setscrews or damage to the probe body or adapter may
occur.
NOTE: The 5562 Probe Assembly can be deployed without the probe guard attached. When doing so,
application related precautions must be considered or system performance can be compromised.
Deployment without the guard is preferred as the effects of low water flow and fouling are
reduced, but exposed sensors or the DO membrane, can be damaged if not properly protected.
3. Attach the stop cap to the end of a PVC pipe using PVC cement, as per instructions on the cement
can label, ensuring that the stop cap is positioned straight and the pipe is fully inserted.
4. 5205 Only: Firmly mount PVC pipe to permanent structure. Skip to Step 9.
5. Loosely fasten two 1½” u-bolts on each mounting plate to the railing, orientated as shown in
Figure 3-7.

7. Slide the uncapped end of the PVC pipe up through the 2” u-bolts until there is approximately 1”
of the PVC pipe above the upper mounting plate, and tighten 2” u-bolts. Note: Do not over
tighten u-bolts or deformation of the PVC pipe may occur.
8. Tighten all remaining u-bolts to secure pipe.
9. Slowly slide the 5562 Probe/Adapter Assembly down the PVC pipe until it rests on the Stop Cap.
10. Connect the cable to the 5200 Monitor.
3.6 Wiring the System
WARNING: All wiring involving connections to mains power must be performed by a qualified licensed
electrician, and must conform to all locally applicable electrical codes. Any mains power circuit
connected within the YSI 5200 enclosure must be protected by a Ground Fault Circuit Interrupt device.
Do not make connections while power is applied. Disconnect power before proceeding.
WARNING: The 5200 utilizes sensitive solid-state devices that can be damaged by static shock.
Installers must observe accepted ESD (Electro-Static Discharge) procedures while connecting cabling to
the 5200 I/O plate or damage may result.
The 5200 Monitor has one MS-19 connector and three compression fittings in the bottom of the monitor
housing. The two larger compression fittings can be replaced with ¾ inch conduit fittings. From a front
view, the smaller compression fitting on the left is for 12-volt power. The opening on the right is for
communications and I/O wiring and the center opening is for relay wiring.
NOTE: The 5200 Monitor is supplied with components necessary to make reliable electrical connections.
When received, pluggable sockets are installed in the power, relay, RS485 and auxiliary ports.
These sockets are to be unplugged prior to making electrical connections and reinstalled after
connections are made.
CAUTION: It is essential that all sensor wiring be run in a separate cable or conduit from power wiring.

3.6.1 DC Power Input Wiring
12VDC power for the 5200 Monitor may be supplied by the YSI 5578/5579 power supply accessory
provided with the unit, or by a 12VDC source supplied by the user.
CAUTION: The YSI 5578/5579 power supply accessory is for indoor use only, and must be connected to
the 5200 Monitor with a suitable waterproof extension cable if the 5200 Monitor is installed in a damp
location.
For outdoor or damp locations, the YSI 5578/5579 power supply may also be installed in a NEMA 4X
enclosure adjacent to the 5200.
3.6.2 Installing the 5578/5579 Power Supply
When using the 5579 power supply it should be wired as follows: (see Figure 3-9)
• Connect the Inline Power Ferrite Assembly, YSI# 655385, to the I/O plate power connector. Failure
to do so could cause catastrophic monitor failure.
• Route the 5578/5579 power supply wire through the small compression fitting and into the case.
• Connect the 5578/5579 wires to the 4-pole 605223UL Pluggable Socket Connector so that the white
wire goes to Main (+) and black wire to Common (-).
• Connect the 4-pole 605223UL Pluggable Socket Connector to Inline Power Ferrite Assembly.
• Tighten compression fitting. See Section 3.3.1 Sealants, Desiccants and Securing the Monitor.
WARNING: A UL Listed DC power supply is required for any installation which is connected to “mains
YSI Incorporated 21 5200 Recirculating System Monitor
supply” or other power source which is “hazardous live” per UL 3101-1 Section 3.5.2.
The 5200 Monitor may be powered by any regulated 8.5–16.5 VDC source that can provide
approximately 800mA of current and is isolated from mains supply by double or reinforced insulation.
(An unregulated supply may also be acceptable if the peak output voltage does not exceed 16.5VDC.)
WARNING: A UL Listed slow-blow fuse with a maximum current rating of 1A must be connected in
series with the positive terminal of any power supply not provided by YSI.
CAUTION: Power supply voltage above 16.5VDC may permanently damage the 5200 Monitor.
When the front panel of the 5200 Monitor is removed, take care not to drop the cover since it is not
hinged to the Monitor.
CAUTION: The sensitivity and stability of the monitor will be impaired if the monitor is not grounded.
Do not apply power to the Monitor until all electrical connections are verified and secure. Connect earth
ground to the 5200 I/O plate (see Figure 3-8 I/O Plate).
3.6.3 Back-up Power
WARNING: A UL Listed slow-blow fuse with a maximum current rating of 1A must be connected in
series with the positive terminal of the back-up supply.
The 5200 Monitor will automatically switch to auxiliary battery back-up operation if primary voltage
drops below 8.5 VDC, providing back-up power is connected. For proper back-up power operation, use
the YSI 5578/5579 Power Supply as the primary power source. Use of a different primary power supply
may prevent proper switching to back-up power.
WARNING: A UL Listed DC power supply is required for any installation which is connected to “mains
supply” or other power source which is “hazardous live” per UL 3101-1 Section 3.5.2.
The auxiliary power source is user supplied and can come from a variety of choices including lead acid or
gel cell external batteries. The 5200 will not charge batteries, so quality assurance maintenance
procedures must be established if batteries are used as the back-up power source.
Input power requirements for back-up operation are the same as primary power, 8.5–16.5 VDC at
approximately 800mA. With no primary power, when the back-up voltage falls below 7.0 volts the 5200
will cease to operate properly.
Connecting back-up power to the 5200 Monitor
Refer to Figure 3-9.
• If necessary, disconnect power to the 5200 Monitor
• Route the back-up supply wire through the compression fitting and into the case. See Section 3.3.1
Sealants, Desiccants and Securing the Monitor.
• Connect the back-up wires to the 4-pole 605223UL Pluggable Socket Connector so that the positive
wire goes to the Back-up (+) terminal and the negative wire goes to the Common (-) terminal.
• Connect the 4-pole 605223UL Pluggable Socket Connector to Inline Power Ferrite Assembly. Failure
to do so could cause catastrophic monitor failure.
• Connect the Inline Power Ferrite Assembly to the I/O plate power connector.
IMPORTANT: After completing system installation, test back-up power by removing main power while
all control/alarm relays are energized. At cold temperatures, logged data may be lost due
to temporary power loss when switching to battery backup power.
YSI Incorporated 22 5200 Recirculating System Monitor
CAUTION: The sensitivity and stability of the monitor will be impaired if the monitor is not grounded.
Do not apply power to the Monitor until all electrical connections are verified and secure.
3.7 Communications Method
The 5200 has three methods of communication:
Ö RS232 TCP/IP Serial Port—to directly connect with a computer or network
Ö Modem—to communicate with a computer or pager via phone line
Ö RS485 Network—to directly connect with other 5200s
3.7.1 RS232 and TCP/IP Port
RS232 serial and TCP/IP communications are made through the TCP/IP port. This port can be
permanently connected to a PC or network for continuous monitoring applications, or to the 5201 Modem
sending alarm messages via phone. The RS232/TCP/IP port uses a standard RJ-45 connector.
Two snap on ferrite assemblies, YSI# 655361, are included with the 5200 Monitor. Wires being
connected to the communication port need to be routed through the ferrites as shown in Figure 3-9.
Failure to do so could cause catastrophic monitor failure.
RS232 PC Connection
When connecting the 5200 via the serial port to a PC for continuous operation, use an inline RS232 OptoIsolator device (YSI# 5285 or equivalent) to prevent ground loops. Failure to use this device may cause
incorrect DO, pH, ORP and conductivity data to be displayed and logged. Mount the isolator as close to
the PC as possible or in an area where it is protected from moisture.

Supplied with the 5200 are a YSI# 655384 Straight-pinned Cat 5 EIA568 compliant network patch cable
and pre-wired YSI# 655383 RJ-45 to DB-9 Adapter. The supplied cable and adapter are only intended to
be used for software upgrades or downloading data. Do not use this cable for long-term installation as the
compression fitting cannot form a proper seal. See Section 3.3.1 Sealants, Desiccants and Securing the
Monitor.
Bulk cable for permanent installations must be round (to allow the compression fitting to seal) and should
be purchased locally. A crimping tool will be required to install RJ-45 connectors to each end of the
cable.
IMPORTANT: 1. The connector that is to connect inside the case should be crimped after the cable is
run through the compression fitting.
2. Round cable must be used so a watertight seal at the compression can be achieved.
TCP/IP LAN Connection
An Ethernet serial server is required to connect the 5200 to a LAN. The serial server must be assigned a
static IP address.

Table 3-1
To connect the 5200 to an EIA-232 device, it needs to be determined if the device connector wiring
follows the standard for data terminal equipment (DTE) or for data communication equipment (DCE). In
general, modems are wired as DCE devices and all other devices are wired as DTE; however, some
equipment manufacturers may deviate from the standard. In most cases, you use "straight through" RJ-45
cable. If you use "crossover" RJ-45 cable, the RJ-45 pins will be reversed.
3.7.2 5201 Modem
The YSI 5201 Modem is available only for use within the United States. For modem support outside the
US, an external modem registered for use within the local country is required. See Section 17
International Modem Support.
The YSI 5201 Modem mounts inside the 5200 case and connects to the RS232/TCP/IP Port. Refer to the
5201 Modem Installation Instructions, included with the modem, for details.
CAUTION: The phone line entering the 5200 case must be #26 AWG wire and must be sealed where it
enters the case or the instrument may be seriously damaged.
CAUTION: The ground wire from the 5201 Modem must be connected to the ground screw on the 5200
I/O plate.
3.7.3 RS485 Network
Connecting 5200s via the RS485 network is described in 8.1 RS485 Network.
YSI Incorporated 25 5200 Recirculating System Monitor
3.8 Grounding Information
This section contains important installation information regarding grounding of the 5200 Monitor.
Connect earth ground to the 5200 I/O panel as described below in 3.9 Safety ISSUES.
The probe is powered by the 5200 Monitor and will be operated with a “floating” ground reference. This
requires that the probe not be individually grounded. Grounding the probe individually will cause a
“ground loop”; i.e. one conductor of the probe output grounded common to both the probe and the
monitor. Grounding the probe will cause significant performance problems with the sensors and likely
result in erroneous readings.
CAUTION: Do not ground the probe body.
All tanks should be electrically grounded via a ground probe.
3.9 Safety Issues
The electrical system must be grounded via the I/O plate to avoid possible electrical shock or damage to
the equipment (see Figure 3-8 I/O Plate).
WARNING: Turn off all power and assure power “lockout” before servicing to avoid contact with
electrically powered circuits.
To avoid possible electrical shock, do not touch other circuit components when making adjustments to the
5200 Monitor circuit board. Disconnect external power to the unit before connecting or disconnecting
wiring.
3.10 Lightning and Surge Protection
Surge protectors are strongly recommended to protect from secondary surges and lightning on outdoor
installations.
Surge suppression devices should be located on the AC line supplying power to the 5200 Monitor and any
signal lines connecting the 5200 Monitor.
AC line voltage surge suppressors protect field equipment on any AC line to ground from damage due to
electrical transients induced in the interconnecting power lines from lightning discharges and other high
voltage surges. The unit should include noise filtering, common mode and normal mode suppression and
nanosecond reaction time. Surge suppressors should be internally fused to remove the load if the unit is
overloaded or the internal protection fails.
Signal line suppressors protect low voltage signals and relay outputs from damage due to electrical
transients induced in the signal lines from lightning discharges or nearby electrical devices. Signal line
suppressors should be installed at each end of an analog loop. Relay outputs should be protected at the
receiver end. Signal line suppressors should consist of a three-element gas tube followed by metal oxide
varistors and suppressor diodes. The protective elements should be matched such that high-energy surge
voltages trigger the gas surge arrester, while low energy or surge voltages affect the MOV’s and
suppressor diodes.
Lightning protection devices should be located as close to the monitor as possible and wired in
accordance with the National Electric Code in approved watertight enclosures.
CAUTION: This or any other installation procedure cannot protect against a direct lightning strike. YSI
Incorporated cannot accept liability for damage due to lightning or secondary surges.

4.4 Preparing the YSI 5561 Probe Module
To prepare the YSI 5561 Probe Module for calibration and operation, you need to install a new DO
membrane cap. Refer to Section 4.6 Membrane Cap Installation for details.
4.5 Preparing the YSI 5562 Probe Module
To prepare the YSI 5562 Probe Module for calibration and operation, you need to install the sensors into
the connectors on the probe module bulkhead. In addition to sensor installation, you need to install a new
DO membrane cap.
4.5.1 Sensor Installation
Whenever you install, remove or replace a sensor, it is extremely important that the entire probe module
and all sensors be thoroughly dried prior to the removal of a sensor or a sensor port plug. This will
prevent water from entering the port. Once you remove a sensor or plug, examine the connector inside the
probe module sensor port. If any moisture is present, use compressed air to completely dry the connector.
If the connector is corroded, return the probe module to your dealer or directly to YSI Customer Service.
Refer to Section 14 Warranty and Service Information.
Conductivity/Temperature and pH, pH/ORP Sensor Installation
