Lightning And Surge Protection - Xylem YSI IOEM Safety And Installation Manual

Notes:
- During upload, any active IOEM/REM devices are placed into Service
Hold which de-energizes any active systems including energized relays.
See SVR Hold Menu in 5X00 user's manuals for additional information .
- No "off" event is created for IOEM/REM channels that are placed in
Service Hold during firmware update process.
- Systems are reset when power is cycled after downloader;
- IOEM/REM total download time is < 1 minutes. IOEM/REM module
will automatically reboot at firmware upload completion;
- Autopoll must be shut down when firmware is uploaded to 5X00;
- All logs and unit configuration are retained when 5X00 firmware is
updated.
- Firmware Updater information is also included in AquaManager
Help>Firmware Updater>Updating Instrument Firmware topic page.
Flash Programmer Updater Messages
The Firmware Updater program may respond with one of the following messages
to indicate that the upload did not occur.
"Timed out" or "Could not find Unit" messages usually indicate a communication
problem between PC and expansion module. Reconfirm AquaManager Firmware
Updater com port setting and RS232 connections. Power cycle the instrument,
close and reopen AquaManager and perform upload firmware steps again to see if
communication problem is resolved.

"Unit is Up-To-Date" indicates that the expansion module has most recent firmware
and upload is not necessary.
11. Remove RS232 communication cable.
12. Close front panel - page 32.

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 IOEM and REM and any signal lines connecting the IOEM
and REM.
• 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.
