TROUBLESHOOTING
Diagnostics Table
Before attempting repair or
replacement, be sure that all
installation and configuration
procedures have been followed
and that the unit is wired properly,
including output excitation. Verify
that 12-32V power is applied to the
unit. If using output channels,
verify that output excitation has
also been provided.
If your problem still exists after
checking your wiring and reviewing
this information, or if other
evidence points to another
problem with the unit, an effective
and convenient fault diagnosis
method is to exchange the
questionable unit with a known
good unit.
Acromag’s Application Engineers
can provide further technical
assistance if required. Repair
services are also available from
Acromag.
POSSIBLE CAUSE
POSSIBLE FIX
Green RUN LED does not light…
In3.3V rail has failed.
Return module for repair.
Green RUN LED flashes continuously…
A network link has not been
established.
Check your cable and switch/hub
connections. Once a link is established, the
green Run LED should not continue to blink
but remain ON. If it continues to blink, then
the cable/connection is bad, or the firmware
may have been corrupted.
Unit was not connected to
network upon power-up, or
network cable is bad.
The RUN LED will continue to blink as the
unit initially hunts for a network link.
Connect a network cable to the unit to allow
it to complete its initialization and stop the
blinking. Note, this only occurs for the initial
network communication following power-
up.
Unit failed to boot firmware
(Internal Firmware Failure).
A continuously flashing green Run LED can
signify the unit has failed to initialize and
may require repair if you are sure you have a
good network connection and proper power
voltage. Return module to Acromag for
repair/reprogramming.
Unit Fails to Start-
up or Initialize…
Input power voltage below 12V,
or input supply is current-
limited below twice the unit’s
current draw?
Check your power voltage and make sure
that it is at least 12V and of sufficient
capacity to handle inrush current (select a
current capacity at least 2x the maximum
current draw of the unit).
Cannot Communicate With Module Over Network…
Power ON at Module?
Check power. Is Green Run LED ON?
Using Wrong IP Address
You could either change the IP address of
the module, or your host PC network card so
that they both match subnet address
domains. The easiest solution is to connect
to the unit via USB and change the IP
address setting of the module.
Many Communication Errors…
Is Cable segment longer than
100M?
The maximum distance between two nodes
on an Ethernet network is limited to 100
meters using approved cable.
Correct Cable Type
Shielded CAT-5/5E cable, equivalent or
better, is recommended.
Missing Earth Ground
Connection?
Connect earth ground to power minus
terminal at TB6-23 (DC-).
