Maintenance
Connect (see 1SDH001330R1002)
PC Power exceed The average power limit setting of the Power Controller has been exceeded
Rating plug Rating plug not present, value or size incompatible with Ekip Touch parameters
Zone Selectivity Diag Error in zone selectivity connections (Hardware Selectivity)
Toroid S.G.R. Check connection and state of current sensor
Fault in connection of sensors to Trip unit; check status of sensors, including
Sensor L1/L2/L3/Ne external Neutral, or call ABB
Check current sensors, status of terminal and cables connecting to Ekip Touch
TFTP server enabled and/or configuration session open on module Ekip Com
Configuration Session
IEC61850 or Ekip Hub
The software versions between Mainboard and display (Ekip Touch) are not
compatible with each other: To restore compatibility, please consult ABB.
NOTE: modification of all parameters is inhibited via display; if present,
Software Not Compatible
protections L, I and Iinst are active and function with the parameters prior
to the alarm (parameters of previous unit are active if display has been
replaced)
CB status CB state incorrect (esample: current present but CB in open state)
Switchboard Actor Check configuration and connection of Ekip Link module
communication Error
Disconnection of Trip coil detected, check functionality
TC disconnected
Check Trip coil, status of the terminal and cables connecting to Ekip Touch
Contact Wear Make sure that the contacts/poles are in good condition.
