Presentation Ekip T&P and Ekip Programming allow the protection trip unit to be connected to Ekip Connect software and
to access parameters and commands that cannot be accessed directly from the front interface: a description
of the various functions is given below.

The additional protections available via Ekip Connect are described on page 25.

Maintenance The Maintenance function allows signalling to the user, via LED, that:
• One year has passed since the last maintenance.
• Contact wear has increased by more than 10% compared with the value at the last maintenance.
Via Ekip Connect there are two selections available:
• Activation: it allows to the maintenance function to be activated.
• Reset: it allows confirmation of maintenance on the trip unit; the present date and contact wear values
are recorded, and the signal is reset.
The reference date is that of the internal clock, and the elapsed time is calculated both with the trip unit on
and off (provided that the internal battery is working).
NOTE: manual modification of the date can cause variations in the calculation of the time
elapsed, and therefore in the date of the next maintenance.
NOTE: the maintenance signal due to increased contact wear is active for values higher than
20 %.

Local Bus In order to activate communication on the Local Bus with the Ekip Link, Ekip Multimeter or Ekip Signalling
10K modules, the Local Bus parameter must be enabled.
NOTE: communication with the modules is active if the auxiliary power supply is present.

Date and time The Ekip Dip trip unit has a user-adjustable internal clock.
Setting the date can be useful for some functions such as the recording of trips and minimum and maximum
currents, and maintenance.
The clock is active if the internal battery of the trip unit is working.
