Ethernet (Tcp/Ip) Module Communication; Step 10 Install And Wire Ioem/Rem Instruments; Lightning And Surge Protection; Sealants, Desiccants, And Securing 5X00 - YSI MultiDO 5400 User Manual

Test RS232 Communications
Apply power to 5X00. Insert node into AquaManager program. See AquaManager
Help to insert node and configure communication in PC application. Poll node. If
wired and configured properly, AquaManager will obtain 5X00 configuration and
5X00 logs.

Ethernet (TCP/IP) Module Communication

The optional serial to ethernet device must be installed on the 5X00 control board
when using TCP/IP for communication. Installation instructions are provided with
the optional serial to ethernet device.
Notes:
- See Menus → System → Communications → Ethernet - page 92 for configura-
tion information.
- An SMTP server accessible by the local network must be provided for eth-
ernet connection.
Consult the network administrator to verify compatibility for ethernet configura-
tion.

Step 10 Install and Wire IOEM/REM instruments

1. Perform steps 1-4 of 5X00 installation and steps 5 - 8 as required for
the application.
Note:
- At step 8, Wire Network - page 60, IOEM and REM instruments are always
slave devices on a network.
2. Follow all installation and wiring steps as required for application as
provided at Chapter 3 of separate manual "IOEM and REM Safety and
Installation Guide. "

Lightning and Surge Protection

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. Surge protection devices
are strongly recommended to protect your equipment from secondary surges and
lightning on outdoor installations. Follow the recommendations provided when
choosing and incorporating surge protection devices into your operation:

Recommendations:
•
Surge suppression devices should be located on the AC line supplying power
to the 5X00 and any signal lines connecting the 5X00.
•
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 5X00 as pos-
sible and wired in accordance with the
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.

Sealants, Desiccants, and Securing 5X00

Environmental conditions can promote the formation of condensation in and around
the 5X00. It is very important to follow the steps below to prevent damage to the
electronic components and extend the life of the 5X00 system.
1. Place solid rubber grommets in bulkhead fittings that have no electrical
connections.
2. If using optional conduit fittings (YSI p/n 065926UL) in place of bulkhead
fittings, industrial encapsulant (YSI p/n 065921 conduit sealer) must be
used to prevent moisture from entering the 5X00 enclosure. Apply the
sealant after all wiring and connections are complete. Failure to use
industrial encapsulant may result in damage to the 5X00.
3. Desiccant pack must be replaced whenever the 5X00 enclosure is opened
(Desiccant pack, YSI p/n 006506). Desiccant absorbs moisture captured
within the enclosure.
