Menu The specific configuration area will activate in the Settings-Modules menu if the Measurement module is
detected correctly by Ekip Touch..
The following parameters can be configured in this menu:
Parameter Description Default
Voltage Transf.
Selects the presence or absence of the external transformer Absent
Rated voltage
Available in the absence of a transformer; defines rated voltage
Un.
The value is given as absolute value (Volts) and can be set
within the range: 100 V to 690 V with variable steps.
400 V
Primary voltage
Available in the presence of a transformer; defines rated
voltage Un of the installation.
The value is given as absolute value (Volts) and can be set
within the range: 100 V to 1150 V with variable steps.
400 V
Secondary voltage
Available in the presence of a transformer; defines the
secondary voltage of the transformer.
The value is given as absolute value (Volts) and can be set
within the range: 100 V to 230 V with variable steps.
100 V
Positive Power flow
Defines the power flow required for D protection; there are 2
options available (page 64):
• High
→
Low: the power flows from the low terminals to the
high ones (load connected low)
• Low
→
High: opposite power flow (load connected high)
High
→
Low
Neutral connection
Available with 3P CB; allows the presence of the external
Neutral to be enabled.
NOTE :
presence of the neutral activates phase voltage
measurement
Absent
About
The About-Modules menu contains the specific menu of the module with the serial number and version of
the module itself.
Test The Measurement module must be disconnected from Ekip Touch (according to the procedure available
on the front label) and the external sockets must be disconnected from the terminal box in the case of
phase isolation tests
(1)
; it is not necessary to disconnect the module in case of dielectric test.
(1)
disconnection to be performed also in the presence of Ekip Touch without Measuring package
Replacement
The Measurement module can be replaced on its Trip unit, for details consult document 1SDH002013A0001 .
If the Measurement module is replaced, module change is indicated on the display by an alarm in the
diagnosis bar when the apparatus is powered for the first time.
To install the new module:
• Confirm the installation module which appears automatically on the display
• Execute manual control, available in the
Settings menu (page37)
WARNING! if the Class 1 Power & Energy Metering package is present, module
replacement could impair the performance values indicated on page 116; consult
ABB to assess solutions able to comply with your requirements
