Making the pneumatic connection to the product
High pneumatic pressure!
Risk of serious injury or death.
Switch off the compressed air supply to the relevant system component before
installing, removing or connecting the product to the pneumatic system.
Secure the system against being unintentionally switched on again.
• For the compressed air and operating pressure specifi cations, see page 64.
• Depending on the order parameters (PN), the as-delivered condition of the
pneumatics system is:
– Order parameter PN = 2: The HQ 2/U-H can be moved from the center position
(without pressurization) to the upper position (TFE 1, TFE 2).
– Order parameter PN = 3: The HQ 2/U-H can be moved from the center position
(without pressurization) to the upper or lower position (TFE 3, TFE 4).
You can fi nd the function plans (TFE ...) for control tasks in transfer systems in the
appendix starting on page 65.
