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 on and
Power
communication with Trip unit present.
• flashing not synchronized with the Power led of Ekip Touch (2 fast flashes per
second): module on and communication with Trip unit absent
Indicates the communication status on the bus:
• off: device off line (with Status led off)
Network on)
Status (1) • on steady: device on line, and assigned to a master (operating condition)
• on flashing: device on line, but not assigned to a master (device ready to
communicate)
Indicates the communication status on the bus:
Network • Off: no error.
Status (2) • On fixed: device in bus off, or Network Power absent.
• On flashing: I/O connection (cyclic data) in timeout
the device has not yet sent the Duplicate ID sequence in line

IMPORTANT:
• move the dip-switches before connecting the module to Ekip Supply and the network
• the termination resistors must never be included in the nodes; inclusion of this capacitance
could lead to a network with improper termination (impedance too high or too low), which
could potentially cause a failure. For example, removal of a node comprising a termination
resistor could lead to network failure
• the termination resistors must never be installed at the end of a drop line but only at the
ends of the main trunk line
