a) One cycle consists in a stroke of 40 mm in both directions (i.e. 40 mm to open + 40 mm to close), based on
an average load of at least 30 % of the rated thrust with the ability to transmit 100 % of the rated thrust for at
least 10 % of the travel.
b) One start consists of a movement of at least 1 % of the minimum stroke in either direction, with a load of at
least 30 % of the rated thrust. The cyclic duration factor (i.e. the ratio between the running period and total
period) shall be not less than 25 % (e.g. 1 s running and 3 s resting).
c) One start consists of a movement of at least 1 % of the minimum stroke in either direction, with a load of at
least 30 % of the rated thrust.
1.11 Packing, transport, storing and unpacking
Surfaces without surface treatment are treated by conservation preparation MOGUL LV 2-3 before
packaging .
Conservation is not necessary if the following storage conditions are complied with:
• Storage temperature: -10 to +50 °C
• Relative air humidity max.80 %
• Electric actuators and their accessories must be stored in dry, well ventilated covered spaces, protected
against impurities, dust, soil humidity (by placement to racks, or on palettes), chemicals and foreign
interventions
•
There shall be no corrosive gases present in the storage areas.
