KEYBOARD
Some pages request user entry of characters. When this type of
input is required, a keyboard page appears, as shown in Figure
58. The text box at the top of the screen displays the current (or
default) setting of the user input. The user can add to this text,
clear it, or change it.
The Shift key on the left side of the screen shifts between upper
and lowercase characters. Pressing the Shift key toggles the
keyboard from one mode to the other (continuous pressing of the
Shift button is not required). The OK button should be pressed
when the user is done entering the text input. The Cancel button
on the bottom of the screen allows the user to ignore any text
changes that have been made and keep the original text value.
Pressing the OK or Cancel buttons returns the user to the page
displayed prior to the keyboard page.
LOGIN
Pressing the Login button allows entering the password from a
keyboard as shown in Figure 58. After the password is entered,
the OK button is selected. The Cancel button aborts the password
login.
WARNING: Explosion Hazard. Improper conguration can cause
fuel buildup and explosion. Improper user operation may result in
property loss, physical injury or death.
Using the OI Displays to change parameters must be attempted
by only experienced and/or licensed burner/boiler operators and
mechanics.
CHANGE PARAMETER SETTINGS
Change parameter settings by selecting the parameter on the
page. A dialog box displays for the parameter with controls
allowing the user to change the value (see Figure 59 on Page 55).
After changing the setting to a new value, press the OK button.
Pressing the Cancel button leaves the parameter unchanged.
The changed setting is reected on the screen and sent to the
control when the OK button is pressed.
CONFIGURATION PASSWORD
Some parameters require a valid conguration password be
entered by the user before the parameter can be changed. The
password need only be entered once while the user remains on
the conguration pages. Leaving the conguration pages ends
the scope of the password.
Three levels of access to Burner Control parameters are
permitted. Each access level has dened rights when interfacing
with conguration and status parameters within the controls.
End user: The end user can read or view the control
parameters and be allowed to change some operating
parameters, CH setpoint as an example.
Installer: The installer can read all control parameters
and change default allowed parameters. This access
level is used to customize the control for a particular
installation.
OEM: The OEM can read and change all parameters,
change sensor limits and burner control safety
parameters.
Different passwords exist in the Burner Control for each access
level. The end user level requires no password, but the installer
and OEM levels have unique passwords dened for them.
The installer and OEM passwords can be changed in the Burner
Control after logging in with the current password. When the
password is changed, it is saved for all future logins.
Note: For the S7999B System OI display, each boiler in a
multi-boiler conguration has its own set of installer and OEM
passwords. To avoid user confusion, the passwords should be
changed to the same password in each control, but there is no
requirement to do so. Make sure to record your password.
The user is notied that a new password is needed to change
a parameter (or until a password is entered successfully)—see
Figure 57. The user can continue viewing the conguration
parameters regardless of whether a password is entered
successfully.
The Burner Controls maintain a password time-out that limits the
scope of the password entry. Once a password is successfully
entered, the control starts an internal timer that expires after 10
minutes of inactivity. After the timer expires, the user is required
to re-enter a password before a parameter can be changed.
The user is not required to enter a conguration password for a
parameter that has a lower access level than the access level
achieved by an earlier password entry for any conguration
group (as long as the user stays in the conguration pages). The
user only needs to enter a password once until a parameter that
has a higher access level is selected.
