3. OPERATION MODE, SERVICE LIFE OF ACTUATORS
Operation mode
The.actuators.can.be.operated.with.the.type.of.loading.S2.according.to.ČSN.EN.60.034-1..The.run.period.at.temperature.
+50.°C.is.10.minutes;.the.mean.value.of.loading.torque.should.not.exceed.60.%.of.the.value.of.maximum.tripping.torque.Mv..
The.actuators.can.also.work.in.the.regime.S4.
(interrupted run with start-up)
.according.to.ČSN.EN.60.034-1..Load.factor..
N/N+R. is. max.. 25. %;. the. longest. working. cycle.
(N+R)
. is. 10. minutes.
(course of working cycle is shown in the figure).
..
The.highest.number.of.closing.operations.in.automatic.regulation.is.1200.cycles.per.hour..Mean.value.of.loading.torque.with.
load.factor.25.%.and.surrounding.tempe50.°C.is.not.higher.than.40.%.of.maximum.tripping.torque.Mv..
The.highest.mean.value.of.loading.torque.is.equal.to.rated.torque.of.the.actuator.
Corrosion protection
