Honeywell Local Operator Interface S7999B - Manual (Page 14)

S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
65-0303—05 14
Three levels of access to Sola 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 Honeywell's 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 Sola 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 Sola
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
Fig. 17. The user can continue viewing the configuration
parameters regardless of whether a password is entered
successfully.

The Sola 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 Fig.
18. 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 Fig. 18. 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.
