mation concerning the status of the pneumatic circuit:

•If there is no failure, the displays show: F -- -- --

•If there are failures, the display STEAM shows the number of failures occurred (use + or – to scroll all the referenc- es). The display MIX/PAUSE shows the code of the failed component. The display AIR shows the code of the type of

failure.

Failure references are displayed using the codes in tables 7.1 and 7.2.

Figure 7.3 shows an example:

The pneumatic circuit has more than one failures.

The displays show information regarding failure number 2: the back clamp solenoid valve has no power.

To erase faults memory, press PROG until the displays show: F -- -- --

To exit self-diagnosis program, press and together until the displays STEAM, MIX, PAUSE, AIR show pressing times.
