Location of fuses and print trigger mode setting
FUSES and ratings
FUSES MUST BE REPLACED WITH THE SAME TYPE AND RATING
Located on the main PCB:
No; Type ;
Circuits:
F1
T2A ‘Wickmann’
24V (not print head), 5V dc/dc converter & 9V regulator
F2
T2A ’Wickmann’
48V stepper motor drives.
F3
7.5A automotive
24V switched output to print head.
F4
T2A ‘Wickmann’
5V output from dc/dc converter.
Located under the mains inlet on the front panel:
F5
T2A HRC 20 x 5mm
Mains.
Note: The 5V and 9Vdc supplies are derived from the 24Vdc supply. If fuse F1 blows the 5 and
9V supplies will not be present.
PRINT TRIGGER SETTING
Printing can be triggered on the leading (trigger switch closes) or trailing (trigger switch opens)
edges by setting the jumper link shown above to the A or B position.
Position A
Printing is triggered at the start of a trigger pulse (leading edge).
Position B
Printing is triggered at the end of a trigger pulse (trailing edge).
NB.
The jumper link must be fitted to position A or B. A trigger pulse will not be generated if the
link is not fitted.
DISCONNECT THE MAINS CABLE BEFORE OPENING THE CASE
DO NOT WORK ON THE PSU WITH THE MAINS CABLE CONNECTED
Diagram below shows location of DC fuses and print trigger setting link on the rear of
the main PCB, accessible from the right hand side of the PSU.
Attention is drawn to the warning label indicating the presence of dangerous voltages on
the PCB.
