Troubleshooting
DAS is not turning on
Verify Switch to Controller Wiring
Locate the Sm@rt DAS controller in the gear. When the
switch is closed, one of the green LED highlighted in red
will turn on indicating the 24V signal gets to the PLC. If
the light does not come on, check wiring from PLC to
switch and from switch to 24V power supply. Ensure
wires were connected between any shipping splits.
Verify Controller to Indicator Light Wiring
The corresponding green LED highlighted in blue on the
controller indicates the breaker is in maintenance mode.
If this light is green and the blue light does not come on,
check output wires from the controller to the light and
from the light to the power supply. Ensure wires were
connected between any shipping splits.
Verify Communication Modules have power
Check each communication module and verify each has
green LEDs on indicating power as per commissioning
requirements. If not, verify power connection wiring.

Verify device is communicating
Each device will have a MODBUS communication light –
verify that it is green as well when the switch is closed.
Check wiring to ensure all connections are made,
especially across shipping splits.
Verify VL settings
Ensure VL breaker nominal settings are at or higher than
maintenance mode instantaneous settings, and that
instantaneous settings are turned on.
