TROUBLESHOOTING
Diagnostics Table
POSSIBLE CAUSE POSSIBLE FIX
USB Software Appears to Freeze During Communication...
This sometimes occurs if you
quickly attempt to connect or
communicate to the unit
immediately after powering up,
resetting, or restoring the unit. Delay clicking [Open] or [Reset Device]
immediately after powering-up until the unit
and its module have initialized (wait up to 15
seconds), otherwise the data transfer or
reconfiguration may freeze-up. If this
happens, try closing the USB software &
recycling power, then reboot the software
and reconnect after waiting up to 15
seconds (unplugging/ re-plugging USB to the
unit may also help).
Output Signal Appears Noisy or Unstable...
AUX Voltage Output is noisy The AUX voltage output of this carrier is
driven directly by the plug-in uB module. If
noisy, the field input signal may be floating
or is not earth grounded, or perhaps output
COM is not grounded.
AUX output minus is common to
PC USB return which is normally
earth grounded if not isolated. You may have two connections to earth
ground that are at different points if USB is
not isolated and your AUX output is
grounded
Check CJC Setting Refer to your module specifications and
determine the required CJC status for your
model. Enable or disable CJC as required for
your module by setting the channel CJC DIP
switch accordingly.
AUX Voltage Output is Over-
Loaded The AUX voltage output can only drive up to
5mA into loads greater than or equal 1KΩ.
The current output cannot drive
full-scale current of 20mA
— is the
orange output Fault LED ON? At
the output channel.
Your output current load may be OPEN or
have greater resistance than 525Ω. If load
resistance is 525Ω or less, then the output’s
13V rail may have failed or fallen out of
regulation and the carrier can be returned
for repair or replacement.
Service & Repair Assistance
Plug-in uB modules are encapsulated and cannot normally be repaired, except
for possible reconfiguration and factory reprogramming. The carrier itself
contains solid-state components and requires no maintenance, except perhaps
for periodic cleaning. Additionally, the carrier plastic is not meant to be snapped
apart and requires a special tool to do so. It is recommended that a non-
functioning carrier be returned to Acromag for repair or replacement. Acromag
has automated test equipment that thoroughly checks and calibrates the
performance of each unit, and can restore or update firmware if needed. Please
refer to Acrom
ag’s Service Policy and Warranty Bulletins, or contact Acromag for
complete details on how to obtain repair or replacement.
