Interface
the module has three signaling leds:

LEDs
Description
Power
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
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.
Network
Status (1)
Indicates the communication status on the bus:
• off: device off line (with Status led off)
(1)
, or in the error condition (with Status led on)
• 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)
Network
Status (2)
Indicates the communication status on the bus:
• Off: no error.
• On fixed: device in bus off, or Network Power absent.
• On flashing: I/O connection (cyclic data) in timeout
(1)
the device has not yet sent the Duplicate ID sequence in line
Configurations
Resistors can be connected to the CAN bus by configuring the dip-switches at the side of the module:

Move dip-switches 1 and 2 to the ON position to connect Rterm

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
