4.2 Initial
Startup
Turn the power on. Be patient, the start up sequence will take about the same time as it takes a
computer to boot up, approximately 2 minutes. The Status LED will flash, and when boot up is
complete the WebAlert will beep 3 times. Under normal conditions, the Status LED will flash on and
off every second.
The WebAlert Series process monitors have a wide range of capabilities, so the steps required preparing
the site for installation would be different depending upon the capability you will be using.
If you want to program the WebAlert using a laptop computer to connect to the serial port on the front
panel of the unit, go to the section below called “Direct Connection to the USB Port”.
If you have a unit that is equipped with a modem, then you can take full advantage of the WebAlert.
The unit is like a web server. Once you set up an Internet Service Provider (ISP) account for the unit,
you can “surf” to it from any web connected computer to access data or reconfigure the settings. The
unit can also contact you, by email or cell phone text message, in case of trouble. In this case, a
dedicated analog phone line that does not go through a company switchboard for the process monitor
must be provided. For details, go to the section below called “Remote Modem Access: Shoulder Tap.”
The ISP information must be entered into the WebAlert via direct connection to the USB port, via
Ethernet or via the Direct Modem method before attempting a Shoulder Tap connection.
If you have not yet set up an ISP account and wish to program the WebAlert from a remote location, or
if you just prefer the “old fashioned method” of direct modem-to-modem communication, go to the
section below called “Direct Modem Access: Direct Tap.”
If you can use the Ethernet connection installed, then the WebAlert becomes like another device on a
network. You can use your web browser software, enter the unit’s address (assigned by your network
administrator) and access data or reconfigure the unit. You will need to have a network node nearby
(within 100 meters/330 feet) to connect your WebAlert process monitor. See the section below called
“Ethernet Connection to LAN”.
You may also use the Ethernet card in your laptop to communicate with the Ethernet connection in the
WebAlert. This requires a special null cable and the laptop network settings must be configured to
work with the WebAlert. Refer to the section below called “Direct Ethernet (for a WebAlert not
connected to the LAN).”
Uploading Configuration Files
You can save all of the set points from a previously programmed unit, and then import the same set
points into another unit. If you have already exported a configuration file from a previously
programmed unit, you can import that file to this unit in order to make all the set points the same. If you
want to save the set points of this unit for use in future units, or want to program this unit using a stored
configuration file, refer to section 5.14 for specific instructions.
See the appropriate section above, depending upon how you plan on exporting the configuration file;
via a laptop connected to the front panel, via modem, or via Ethernet connection.
