7�3 Commissioning of the basic module �100 and
extension module �105
7�3�1 General information
▶ Ensure that the specified protection and safety equipment is in place and
functional at every stage of the life cycle, such as commissioning, cleaning,
maintenance or repairing, as well as in every operating mode.
Suppression or bridging of the specified safety equipment or removal of
the specified protection equipment is not admissible.
▶ Before commissioning, ensure that the "OFF" operating mode (EN ISO 16092-1,
paragraph 3.4.1.1) is functional to prevent start-up or continuous operation.
▶ Ensure that the "UP/DOWN" jog mode (EN ISO 16092-1, paragraph 3.4.1.2 and
EN ISO 16092-3, paragraph 5.5.1) is functional with a safe reduced velocity
(less than 10 mm/s) and hold-to-run device via the on/off valve .170 and the
retaining valves .145/.147.
The die cushion movement is triggered by the permanent operation of a control
device by the operator.
▶ When closing/extending, ensure that the maximum pilot oil supply flow rate is
limited via nozzle .171 if it is higher than the piston side flow rate at 10 mm/s.
▶ When opening/retracting, ensure that the maximum pilot oil supply flow rate
is limited via nozzle .172 (only if downward movements must be reliably
prevented) if it is higher than the ring side flow rate at 10 mm/s.
▶ Ensure that the ring side is filled sufficiently with hydraulic fluid during
retraction to avoid cavitation.
▶ Ensure that the maximum flow rate of the pilot oil supply is sufficient and
that the nozzle .172 is not too small.
▶ Check the nozzles .171 and .172 during commissioning and adjust them
if necessary.
– Check the nozzles by closing/extending with minimum load pressure and
opening/retracting with maximum load pressure.
– Then update the changed nozzle fitting in the technical documentation of the
machine (hydraulic circuit diagram/parts list).
The load pressure is the sum of the weight of the die cushion and the lower
tool relative to the effective piston chamber surface.
