Resetting Functions
The Reset pushbutton is context sensitive. Its purpose is dependent upon the screen that is presently
being displayed. For example, pressing the Reset key when the demand screen is displayed will reset the
demands but it will not reset the alarms, etc. It is necessary to scroll through the menu tree to the Alarms
screen to reset an alarm. You are not prompted for a password when using the Reset key.
There are two BESTlogic variables associated with the HMI Reset pushbutton. Logic variable TRSTKEY
becomes TRUE when the Reset pushbutton is pressed while the Targets screen is displayed. Logic
variable ARSTKEY becomes TRUE when the Reset pushbutton is pressed while the Alarms screen is
displayed. See Section 8, Application, Application Tips, for examples on the use of these variables.
Entering Passwords
If password security has been initiated for a function, the HMI will prompt you to enter a password when
the Edit pushbutton is pressed. To gain access, you must enter the appropriate password. A field of 8
asterisks appears with the cursor located under the leftmost character position. You can enter passwords
by performing the following procedures:
1. Press the UP or DOWN scrolling pushbuttons until the proper first character of the password
appears. Pressing UP scrolls through the alphabet and then the numbers in ascending order.
Pressing DOWN scrolls through the numbers and then the alphabet in descending order.
2. Press the RIGHT scrolling pushbutton to move the cursor to the next character of the password
and select the appropriate character.
3. Continue the process until the entire password has been spelled out. If the password is less than
8 characters, leave the remaining asterisks in place instead of entering blanks.
4. Press the Edit pushbutton to enter the password. If the proper password has been entered, the
screen will flash ACCESS GRANTED. If an incorrect password has been entered, the screen will
flash ACCESS DENIED and the Edit LED will go out.
5. Once you gain access, it remains in affect for five minutes after the last pushbutton has been
pressed. As long as you continue to press the Edit key for a function for which you have gained
access, the five-minute timer will be refreshed and you will not be prompted for a password.
