5.1.2 Diagnostics
Throughout the diagnostics operation of the machine all functions and
components are monitored. Should an error occur, a fault code is
displayed (see Fig. 5.7). With a text message, such as
”ST_MOTOR1_OPEN_CIRCUIT” many faults can simply be corrected by
the Service engineer. If the text message ”Malfunction” is displayed, the
fault can also be corrected by the Service engineer but requires more
service research. All messages regardless of nature are always connected
with a fault code.
The main self-diagnostic mode, Diagnostics checks the voltages, the
sensors, solenoids and the motors. If a fault is found it will be displayed
as a fault code. This manual lists all fault codes. To correct the fault,
go to chapter:
5.2 Fault Code Descriptions
.
NOTE:
It is normal to receive the code ‘Fault Code 00034’ [STR034] if
no Stacker is connected to the STR.
