21
A
Duplicate print
non autorised
Three conditions are required
for this fault to appear:
-
the serial link is used.
-
the “Print-out no double
up” option must be
selected.
-
two consecutive
attempts must be made
to print the same
message.
Consequences:
The
message is printed only
once.
Check timing of sending of messages and Dtop.
22
D
CRC(RAM)
message
memory lost
The CRC calculated when
the printer is switched on is
different than the CRC
stored.
Consequences:
The messages in the library
are lost.
1- Reprogram the messages.
2- Check the position of the battery jumper on the
CPU.
3- Check the voltage of the CPU battery.
4- Replace the CPU.
25
FPGA
impossible to
program
When printer switched on.
Consequences:
The printer
cannot print.
Replace the CPU.
26
D
CRC message
library incorrect
The CRC calculated when
the printer is switched on is
different than the CRC
stored.
Consequences:
The messages in the library
are lost.
1- Reprogram the messages.
2- Check the position of the battery jumper on the
CPU.
3- Check the voltage of the CPU battery.
4- Replace the CPU
27
A
Timeout speed
meassurement
(20sec)
If the object traveling speed
is measured by 2 cells
(without a tachometer), the
pulse from the second cell
was not received by the
printer. (time > 20s)
Consequences:
The
message is not printed.
1- Check the cell connections and their operation.
2- Check the distance between the cells.
3- Check the conveyor speed.
28
D
No signal for
speed
meassurement
If the object traveling speed
is measured by 2 cells
(without a tachometer), the
pulse from the first cell was
not received by the printer.
Consequences:
The
message is not printed.
1- Check the cell connections and their operation.
2- Check the distance between the cells.
3- Check the conveyor speed.
