1. Each installation has to be prepared and reviewed very carefully before start-up. Wrong or incomplete wirings can damage the

installation brutally !

2. Each application requires a specific combination of the following parameters:

- Auto/ Semi-auto / Test / Manual / Block mode.
- Island / AMF / PS / FP / LTO / MPE / PMS application type (in AUTO mode PS / FP / LTO can be combined with AMF).
- Back synchronising enabled/disabled (parameter channel 7080).
Wrong parameter settings can damage the installation brutally !

3. To be able to start up in cold conditions, parameter 6181 (Start prepare) can be changed to a higher value to have some

preheating. Do not put this value above 60 seconds to avoid any possible damage.

4. For more information on the Qc4002™ module and its applications, we refer to the Qc4002™ User manual. If you need more

assistance, please contact Atlas Copco.
