Interface
The module has three signalling LEDs:
Figure 35
LED
Description
Power
Reports ON status and correct communication with Ekip Touch:
 off: module off
 fixed or flashing light synchronized on power LED of Ekip Touch: module ON
and communication with Ekip Touch present
 flashing not synchronized with power LED of Ekip Touch (two fast flashes
per second): module ON and communication with Trip unit absent
Network
Status 
Indicates status of the communication on bus:
 off: device off line (with status LED OFF)
(NOTE)
, or in error condition (with
status LED ON)
 Fixed light: device on line, and assigned to a master (operating condition)
 flashing light: device on line, but assigned to a master (device ready to
communicate)
Network
Status 
Indicates status of the communication on bus:
 Off: no error.
 Fixed light: device in bus off, or Network Power absent condition.
 Flashing light: I/O connection (cyclical data) in timeout.
NOTE: the device has not yet sent the in-line Duplicate ID sequence
Configurations
Resistances can be linked to the CAN bus, configuring dip switches located on the side of the
module:
Figure 36
Resistances
Dip
Description
Default
Rterm
1 and 2
Termination resistance 120 
Move dip switches 1 and 2 to ON position to
connect Rterm
Off
IMPORTANT:
 move the dip-switches before connecting to Ekip Supply and to the network
 the termination resistances must not be included in the nodes; including this
capacity could easily lead to a network with incorrect termination (impedance
too high or too low), which might cause a failure. For example, removing a
node that includes a termination resistance could lead to a network failure
 the termination resistances must not be installed at the end of a drop line but
only at the two ends of the main trunk line
