TROUBLESHOOTING
Diagnostics Table
If you still have a problem after
reviewing this information and
checking your power, wiring, and
input module, or if other evidence
points to an unknown problem
with the carrier, an effective and
convenient fault diagnostic
method is to exchange the
questionable carrier and/or carrier
module with known good units.
Acromag’s Application Engineers
can provide further technical
assistance if required and repair
services are also available from
Acromag.
POSSIBLE CAUSE
POSSIBLE FIX
Cannot Communicate with Module with Bluetooth wireless technology...
Blue BLE LED of Carrier Channel does not light
…
Is the BLE DIP switch for the
channel set ON to enable
Bluetooth wireless technology at
the module?
Note that Splitter Functionality
cannot be wirelessly configured,
but this splitter can be optionally
used as a single-channel carrier
for any uB input module,
including Bluetooth wireless
technology enabled versions.
Splitter functionality can only be configured
via wired USB. However, the splitter panel
does support Bluetooth wireless technology
enabled modules. And these modules could
be configured wirelessly for optional
operation as a single channel carrier with a
single output wired to AUX. In this case,
check the BLE DIP switch setting and set it
ON to turn the blue BLE LED ON and allow
wireless linking to a plugged-in Bluetooth
wireless technology enabled module using
the Agility mobile app to reconfigure I/O
functionality (not splitter). Setting this ON
or OFF has no effect on standard microBlox®
modules.
Unit Fails to Start-
up or Initialize…
Check power voltage level and
capacity, making sure that it is at
least 6V and of sufficient capacity
(select a current capacity 2x the
max current draw of
splitter/module at its voltage
level). Note that you can reduce
current consumption by raising
the power voltage level.

Input
Polarity is Wrong…
Are your input terminals
reversed? Current is input and
voltage is positive at input+.
Check your input wiring and observe proper
polarity (refer to uB module’s user manual)
.
Your uB Module Does Not Appear to Work in This Carrier
Is your module a Model
uB45 frequency model?
The uB45 frequency model is not compatible
with the splitter output function.
Output Signal Appears Noisy or Unstable...
Is the uB input module fully
inserted into the carrier socket?
Check that the module is fully plugged into
its socket. Note uB45 models are not
compatible with this splitter.
Have you grounded your input
signal? Ungrounded I/O requires
earth ground connection as
noted in the module
specifications. Be careful not to
connect AUX output to earth
ground without using a USB
isolator (USB carries earth
ground from the PC).
Earth ground keeps isolated signals from
floating and provides a safe shunt path for
destructive transient energy. If your input
source is not already earth grounded, then
refer to its connection diagram and apply
earth ground as noted (inputs typically tie
earth to the IN- terminal, see module wiring
specific to your model). Splitter outputs are
normally grounded at output return.
