CONFIGURATION PASSWORD

Some parameters require a valid configuration 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 configuration pages. Leaving the configuration pages ends the scope of the password.

Three levels of access to Burner Control parameters are permitted. Each access level has defined rights when interfacing with configuration 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 defined 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 configuration 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 notified 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 configuration 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 configuration password for a parameter that has a lower access level than the access level achieved by an earlier password entry for any configuration group (as long as the user stays in the configuration pages). The user only needs to enter a password once until a parameter that has a higher access level is selected.

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 configuration 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 reflected on the screen and sent to the control when the OK button is pressed.
