ENTERING A PASSWORD TO GET TO USER OR ENGINEER’S MENUS
To protect system parameters from being altered by unauthorised people. Two passwords have to be
entered to gain access to available menus which allow changes to be made.
The first 4 button password is the USER menu and gives access to a limited set of menus, e.g. clock
set, LED test etc. The second 4 button password is for the ENGINEER’S menu which gives access to
all menus including the users. A sequence of 4 buttons is accepted as the entry for a password.
TO START THE ENTRY OF THE PASSWORD, PRESS SELECT (3) .
The password display is shown on the LCD and each of the 4 buttons in sequence can now be
pressed.
Default Passwords
The USER password is defaulted to DOWN (5) pressed 4 times.
The ENGINEER’S password is defaulted to + (4) pressed 4 times (or as per customer requirement).
Changing the engineers password is described later.
The user password cannot be changed.

Note: The items that appear in the user menu can be selected from the Engineer’s menu by
toggling the +(4) button. A ‘+’ symbol will appear in the menu next to the item to indicate it is
available in the user menu. Engineer’s menu contains all items.
