BC-3500 Series - Rowe International

Section 4: Troubleshooting
INTRODUCTION
The BC-3500 incorporates major assemblies and components as field replaceable plug-in units. There are several
onboard diagnostic indicators on these assemblies. The information in this section takes full advantage of this design
by isolating possible malfunctions to one or more of these basic plug-in units. This method saves time and requires
little training in electronics.
The most significant troubleshooting aids for the BC-3500 are the power control center LED’s, and the status display
on the computer control center.
POWER UP DIAGNOSTICS
As power is applied to the BC-3500, a series of power up checks are performed by the control computer before
the machine is put into service. The 16-character alphanumeric status display on the control computer is the primary
diagnostic indicator. A secondary indicator is provided by the green reflective/transmissive LED in the bill transport.
The following sequence describes the power up sequence along with what is shown on the status display. The
condition of the secondary indicator is also described.
Action - Turn the Power Switch to the ON position.
