6 - PIN and security

Safety WARNING! the user is responsible for security against unauthorized access and
modification: configure all Trip unit access points (display menu and, if present, Ekip
Connect and remote communication systems) using the access PIN and controlled and
authorized connection systems

Function The PIN code enables access to certain areas of the Trip unit and prevents unintentional setting errors
from being entered via the display.
However, parameters can still be modified without having to enter the PIN via:
• service connector, using Ekip T&P or Ekip Programming and the Ekip Connect application
• bus, in the presence of Ekip Com modules and with Trip unit configured as Remote (page 119).
To ensure your unit is in secure conditions, the Wizard window immediate asks you to change the PIN
code on first power up; this is strongly recommended by ABB (page 17).

Description The PIN code is a number formed by five digits, each of which can be given a value from 0 to 9; the default
value is: 00001 and can be changed in the Settings-New PIN menu.
The PIN code must be entered to:
• change a parameter (including the PIN code itself)
• access the Test menu
Once the PIN code has been entered, all menus can be browsed for two minutes: once two minutes have
elapsed, the PIN code must be entered again (depending on the case in question).
NOTE: the PIN code must also be entered again if a programming session has been annulled
(page 37).

Entry The following page will appear when the PIN code is requested: change (1) and confirm (2) each digit to
complete the entry process.

Figure 26

NOTE:
• if the PIN is wrong, “Wrong PIN” will appear for three seconds after which the entry page
will be displayed again; use the command at the top left to quit
• there is no limit to the number of wrong PIN that can be entered

Disabling The PIN code can be disabled by entering its value as: 00000; In this case, the PIN is only required to
change the PIN itself in the Settings menu.

Recovery Contact ABB directly if PIN code is lost.
