4.4 Access Codes
The Webmaster series controller is shipped with the access codes at default values. In order to
prevent against unauthorized tampering, you will need to change the access codes to your own
values. See section 6.32 for details.
There are three levels of protection. If the Master password is used in the Webmaster
Authentication page, then any set point can be changed. The default Master password is 2001.
If the Calibration password is used in the Authentication page, then sensor calibrations will be
allowed, but other changes will not. The default Calibration password is 2002.
If the Read Only password is used the user will be able to look at any page, but will not be allowed
to make any changes. The default Read Only is 2003.
The default user name is "webmaster." This can and should be changed in the Access Code page.
See section 6.32 for details.
4.5 Initial Startup
Turn the power switch on. Be patient, the start up sequence will take about the same time as it
takes a computer to boot up, approximately 2 minutes. At first the display backlight will blink and
all output LEDS will light. Around 30 seconds later, the display backlight will come on, and the
LEDS will shut off. Then the display will come up, and show you the % complete status of the
start up process. After around 1 minute, the Summary Screen will appear. In 15 seconds, you will
hear 3 beeps, and the controller is ready to go.
The Webmaster Series controllers 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.
Currently the WebMaster has only limited functionality for the local display and keypad. A
majority of the programming must be accomplished using a computer. You will be able to
calibrate all sensor inputs, change access codes, and enter the information necessary to
communicate with the WebMaster via an Ethernet connection (if an Ethernet card is
installed in the controller) or via the modem over the Internet (if a modem card is installed
in the controller). If neither of these communications options are installed, you must use a
direct serial connection to a PC for programming. You may set most set points with the
keypad, but you may not change operating modes (for example, you may change the pump
on time for a biocide add, but not the time of day; nor can you change from a 1 week cycle to
a 2 week cycle).
If you have a stand-alone controller with no communications, but you do have a computer to
connect to the serial port on the front panel of the controller for programming, go to the section
below called “Direct Serial Connection to the RS232 Port”.
If you have a controller that is equipped with a modem, then you can take full advantage of the
Webmaster. The controller is like a web server. Once you let Walchem know that you are an
authorized user, and set up an Internet Service Provider (ISP) account for the controller, you can
“surf” to the controller from any web connected computer to access data or reconfigure the
controller. The controller can also contact you, by fax, email or pager, in case of trouble. In this
case, a dedicated analog phone line that does not go through a company switchboard for the
controller must be provided. For details, go to the section below called “Remote Modem Access:
Shoulder Tap.” The ISP information must be entered into the Webmaster via direct serial
connection to the RS232 port, or via the local keypad before attempting a Shoulder Tap
connection.
