LED Description
Signals the on status and correct communication with Ekip Touch:
• Off: module off
• on steady or flashing synchronized with the Power led of Ekip Touch: module
Power
on and communication with Trip unit present, flashing not synchronized with
the Power led of Ekip Touch (two fast flashes per second): module on and
communication with Trip unit absent
Indicate the status of the contacts of each output:
• off: contact open
• on: contact closed
O SC
NOTE: The LED displays the state of the output: it can indicate
synchronization OK or KO, depending on the contact rest configuration
(normally open or closed)
module is detected correctly by Ekip Touch.
