Maintenance and troubleshooting
3.1 Maintenance
In order to avoid miscounting/detecting errors, it is advised to clean the BC 131 SD regularly and at least
once a week. Dust on the detecting modules, IR sensor(s) and magnetic sensor(s) can affect the
counting result and therefore shall be cleaned thoroughly. You may clean the machine by using the
provided brush or optional cleaning cloth to remove any dust inside the machine.
Also pay attention to the following:
if the temperature is lower than 20 degrees Celsius, please turn on the machine and wait for at
least 3 minutes before counting so that the BC 131 SD can acclimatize;
the BC 131 SD shall be operated at places with good ventilation and kept away from strong
sunshine and strong magnetic fields;
the power plug of the machine shall be inserted to a grounded electrical socket;
assure that the different moving parts are not stained with grease, otherwise the banknotes will
slide and affect the counting.
ATTENTION: do not use any chemicals to clean this machine.
3.2 Software update
The BC 131 SD can be updated very easily by using a special micro SD card and we strongly
recommend this way of updating. This card can be obtained via your supplier and to provide the
correct software the serial number of the machine is needed.
Insert the micro SD card to the micro SD card reader at the backside of the machine. When the display
shows ‘En1’ press both buttons ‘CUR’ and ‘MODE’ simultaneously. Release both buttons when ‘-dn‘
appears in the display and the BC 131 SD will start updating automatically. Only when the display shows
‘donE’ (which will take some time) the software is updated and you must manually turn off the counter.
ATTENTION: if the power is interrupted during updating or when the micro SD card drops out, please
insert the micro SD card again and the BC 131 SD will finish updating automatically.
Updating by USB/computer is also possible. In both cases contact your supplier for more information.
3.3 Removal of jammed banknotes
When a note is jammed inside the BC 131 SD, disconnect the power and open the top cover to remove
the banknote(s). Now close the cover and turn on the power again.
3.4 Adjusting the feeding gap
The feeding gap has already been set to the best position factory wise. Though, when one of the
following counting problems occur, it might be necessary to re-adjust the adjusting screw (see 1.4 Unit
design for the location):
lf frequently notes jam or are not counted smoothly, please turn the adjusting screw anti-clockwise
(-) to make the clearance larger;
lf frequently double notes or chained notes occur, please turn the adjusting screw clockwise (+)
to make the clearance smaller.
ATTENTION: only make minor adjustments to the adjusting screw!
