Once a valid password is entered the message reverts back to the original.
"SYSTEM SECURED" - This message indicates that a user entered password is in effect. This
message switches to "-OPEN- Password is <1>" when unlocked. Informing the operator that the
password is one (1) effectively unlocks the system. This is the factory default and also occurs
anytime the user sets the password equal to “1”. See Section 4.2.10 for details on changing the
password.
"ENTER Password" - Touch on this flashing numerical entry element to enter the password. A
valid password can be up to 7 digits in length. See Section 4.2.1 for a full explanation of the
numerical entry element if necessary.
"Overview" - This is an HMI navigation button which switches the screen back to the Overview.
4.2
System Setup Screens - SECURE ACCESS
The second of two parts which make up the screen package is secure access. This part is intended to
allow the responsible operator to make changes to the many user changeable parameters designed
into the MultiGard 5000 unit.
Once the security check lets the operator into the secure access area a 15 minute time-out timer
starts. Any screen change within the secure access area will reset the time-out timer. If no screen
changes are made within the 15 minutes, the display returns to the overview screen.
NOTE: The security time-out will prevent the system from being accidentally left open for long time
periods. The operator should intentionally leave the secure access area when finished.
The following figure, MultiGard 5000 Screen Hierarchy, Part 1 of 2, summarizes this portion of the
package and can be used as a "road map" to system operation.
