12 | © 2023 ABB | 1SDH001316R1002 - ECN000297030
Commands
Selection of a command implies its immediate execution or opening of an intermediate confirm window.
Correct execution is indicated by a confirm window, which disappears automatically from the display.
Certain commands, selection of which immediately activates the respective test sequences without any
confirm window, are an exception to this rule:
•
Auto Test
• Ekip Signalling 2K module commands
IMPORTANT: confirmation on the display refers to launching the command, not to
verification of the operation required, which is at the user's charge whichever type of
command is concerned: reset parameters, display, open/close contacts
Exceptions
Before validating a change to a parameter, the Trip unit checks all its parameters to make sure there is no
conflict or incorrect condition:
• if the Trip unit detects an incorrect condition, the relative details appear on the display and
parameter modification is annulled.
Before executing a command, the Trip unit checks all its parameters to ensure there is no conflict or
incorrect condition:
• if the Trip unit detects an incorrect condition, the relative details appear on the display and
command execution is annulled.

4 - 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 27).
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.
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
11 ).
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 8
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.

Protections
1 - Protections - Introduction
Operating principle
The protection functions are available with all Ekip Touch models and versions.
Each protection is associated with a different signal (current, voltages, frequencies, powers, etc) but the
operating principle is the same:
1. If the signal measured exceeds the set threshold, the specific protection activates (prealarm and/
or alarm condition).
2. The alarm appears on the display and, after a period of time (timing t t), depending on the
protection parameters set, can convert into a trip command (TRIP) transmitted to the internal
Trip Coil of the CB.
NOTE:
• if the signal measured drops below the set threshold before the trip time has elapsed, Ekip
Touch quits the alarm and/or timing status and returns to the normal operating condition
• all protections have a default configuration: check the parameters and change to suit the
installation requirements before putting into service
• to allow circuit-breaker tripping to be controlled by a specific protection, the protection
itself must be enabled
References
Many of the protection thresholds are displayed in two different quantities: absolute value and relative
value.
The relative value depends on the type of measurement:
Type of protection Reference Description

Voltage Un Line-to-line voltage setting
Frequency fn Frequency setting

Neutral Protection
Neutral protection is used to characterize protections L, S and I differently on the neutral phase.
Represented as a percentage, it defines the multiplication factor applied to the tripping thresholds of the
protections (example: 50% = the tripping threshold of the neutral is half the phase threshold).
The protection is available with the 4P and 3P + N configuration; the configuration parameters can be
accessed via the
Settings menu
NOTE: the Trip unit will not accept changes to the thresholds of protection L (I1) and of the
Neutral (InN) unless the following limtation is complied with: (I1 x InN) ≤ Iu; Iu is the size of
the circuit-breaker
WARNING! With 150% and 200% threshold; if the measured neutral current exceeds 16In,
the Trip unit resets the protection to 100% by itself
T Protection
T protection protects against abnormal temperatures measured and transmitted to the sensor inside the
unit; temperature verification is always active and includes three operating states:
State Temperature range [°C] Ekip Touch actions
Standard -25 < t < 70 Normal operation; display state depending on type (1)
Warnings -40 < t < -25 or 70 < t < 85 Warning led @ 0.5 Hz; display state depending on type
(1)
Alarm t < -40 or t > 85 Display off; Alarm and Warning leds @ 2 Hz; TRIP if
Trip enable is activated
(1)
with Ekip Touch, the display remains on within range: -20°C / +70°C; with Ekip LCD, the display
remains on within range: -30°C / +80°C
All protections enabled in the unit are active in all operating states.
Other protections
The Iinst, Harmonic distortion, Hardware trip and Current threshold protections are described in detail in
the manual 1SDH001330R1002.

ANSI / IEEE C37-2 codification

t
t
calculation is valid for If values that have exceeded the trip threshold of the protection. Use fault current and threshold values
expressed in In to calculate t
t
, as shown in the example.
(3)
Tolerance values valid with Trip unit supplied at full rate or by auxiliary power supply, trip time ≥ 100 ms, temperature and current values
within operating limits. The tolerance values of the table after the notes apply if the conditions are not guaranteed
(4)
All thresholds can be selected in the presence of auxiliary power supply. In self-supply conditions, the minimum threshold is limited to:
0.3 In (with In = 100 A), 0.25 In (with In = 400 A) or 0.2 In (for all the other sizes)
(5)
Time MCR is the time for which the protection remains active after the circuit-breaker has closed. Similarly to protection I, the trip time
cannot be adjusted
(6)
Startup can only be activated with function set at fixed time
(7)
For the startup functions, the time indicated is the period during which the protection remains active with the different threshold,
calculated from the point in which the startup threshold is exceeded
(8)
With t4 = instantaneous, the maximum tolerance is 50 ms
(9)
L protection: the trip time of the protection is forcibly set at 1 s if the calculation results give a lower theoretical tt value and/or if the
current reading is more than 12 In
(10)
G protection: the protection deactivates automatically if disconnection of one or more sensors is detected or if current If is more than
8 In (with I4 ≥ 0.8 In), 6 In (with 0.5 In ≤ I4 < 0.8 In), 4 In (with 0.2 In ≤ I4 < 0.5 In) or 2 In (with I4 < 0.2 In)
(11)
S and G protection: with curve t= k/I
2
, the protection trip time is forced to the set value if the calculation results give a theoretical tt
value lower than the parameter itself
(12)
A maximum value of I4= 1200 A is allowed for UL versions; if an attempt is made to set a higher value, the trip unit signals an alarm and
interrupts the modification
(13)
For UL versions, t2 and t4 can be set at 0.4 s maximum
