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 115).
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
Entry
The following page will appear when the PIN code is requested: change (

complete the entry process.

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
