9 - Additional protections and functions

Additional protections Some protections have additional functions which extend their characteristics and performance:
Name Description Protections
Thermal Reduced trip time in the case of TRIPs within brief L, S
Memory intervals (protection against cable overheating)
Additional parameters for managing TRIP
Zone
selectivity commands between circuit-breakers equipped S, S2, G, D, Gext, MDGF
with the same function
S, I, G, MCR, S2, D, S(V), S2(V), UV,
Blocking of protection on the basis of OV, VU, UV2, OV2, UP, OP, RP, RQ,
Blocks
programmable events OQ, RV, UF, OF, UF2, OF2, ROCOF,
Gext, MDGF
Different threshold of the protection for a
Startup limited time, with activation on the basis of a S, I, G, S2, D, UP, Gext, MDGF
programmable monitoring threshold

Additional protections Installation of certain accessories allows the additional protections to be activated:
Th- Fun-
Name Type of protection Time Additional functions
reshold ction
Earth fault with current Trip enable, Zone Selectivity,
Gext reading by S.G.R. Startup enable, Locking, Pre-alarm
external sensor threshold
Residual current with
Rc corrent reading by
external toroid Rc
Synchronism between
two independent
Synchrocheck voltage sources or
energizing of a busbar

Earth fault with current Trip enable, Zone Selectivity,
MDGF reading by MDGF Startup enable, Locking, Pre-alarm
external sensor threshold

Further details about the protections are given in document 1SDH001330R1002.

Programmable Functions and Ekip Touch has eight programmable commands, which activate on the basis of signals or events. Each
Commands command allows the activation function and event monitoring time to be programmed.
Name Description Menu path
External Trip Sends a TRIP command
RESET Trip TRIP signal reset Advanced - Functions
Activate SET B Changes the protections set, from Set A to Set B
Energy RESET Resets the energy meters Measurements - Energy
Command YO Sends a command to opening coil YO
Command YC Sends a command to closing coil YC Settings - Functions
Changes the configuration, from Remote to
LOCAL Switch On Settings - Modules
Local - Functions
Signaling RESET Reset the contacts of the signalling modules
