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% run-
ning factor indicates that for a 10 minute cycle, it works at constant power
for 4 minutes P S6-40% and without load for 6 minutes (0.4 x rated cur-
rent 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. H2/32
Load cycle S1.
F. H2/33
Load cycle S6-40%.
F. H2/34
Cycle at Pmax without previous load.
