Operating cycles
Load cycle S1
Continuous duty.
Operation with constant load and long enough to achieve
thermal balance.
Load cycle S6-40%
Periodic uninterrupted duty cycle with intermittent load.
Succession of
identical duty cycles, each with a running period under constant load and
another period without load. There is no rest period. The 40 % running
factor indicates that for a 10 minute cycle, it works at constant power for
four minutes P S6-40% and without load for six minutes (0.4 x rated current
Pn).
Cycle at Pmax. without previous load
Periodic intermittent duty.
Succession of identical duty cycles, each with a
rest period. The 40 % running factor means that for a 10 minute cycle, it
works at 1.6xPn for 4 minutes and it rests (no power) for 6 minutes.
F. H2/12
Load cycle S1.
