5.2 MiniCSU-3 Security & Alarms
5.2.1 Password security
MiniCSU-3 features password security for setting of parameter. A valid password is an
alphanumerical code having minimum three and maximum eight characters.
Units leave the factory without a pre-programmed password and the security function is
not active. To activate the security, a password must be programmed. Once that is done,
security can be enabled.
5.2.1.1 Entering a password to gain access to parameters change
When the security function is active any changes to the system settings can be done only
after a valid password was entered. When the ENTER key is pressed to change a
parameter, the display will show a message “Enter Password” on the top line and a
blinking cursor on the right hand side of the bottom line. Using INC and DEC keys scroll to
the first character of the password and press ENTER. The character will be substituted by
a star ( * ) displayed to the left of the cursor. Enter all characters of the password the same
way. If the password is less than eight characters long press ENTER again after last
character. If the entered password was correct the display will return to the selected
parameter ready for modification. If the entry was incorrect following will be displayed
Wrong Password
Panel Locked
There is no limit on password entry re-tries. To abort password entry any of the top row
buttons should be pressed. The display will return to the selected parameter. Once
unlocked, the security is disabled until there is no keypad activity for >1 minute.

If one or more alarm conditions exist at any time the following message will alternate with
the “home” screen for 2 seconds every six seconds in addition to warning LED indicators:
3 Alarms
Press ENTER
In this case, the message indicates that there are three alarms present and they can be
observed by pressing the ENTER button.
When the ENTER button is pressed the most recent alarm name, such as the one shown
below will appear on the display.

Amb Temp High
If no button is pressed again for one minute, the display will revert to the “home” screen
and the sequence begins again.
To view the remaining alarms, use INC and DEC buttons. Pressing the ENTER button will
return the display to the “home” screen. The time and date of any given alarm can be
obtained by entering the ALARM LOG menu.
