3.1.5. Duty Cycle *
1
[Duty cycle data were indicated Clause 3.1.1 Standard Technical Data.--- 16 Rev1]
Exceeding the actuator’s rated duty cycle may cause thermal overload.
Note *1 Type of duty according to VDE 0530 / IEC 60034-1
Short – time duty S2 Intermittent duty S4
The operation time at a constant load is
short, so that thermal equilibrium is not
reached. The pause is long enough for the
machine to cool down to ambient
temperature. [Example, the duration of the
short –time operation is limited to 15min ----
--- 15 Rev0]
The duty is a sequence of identical cyc
l
es which
consist of starting time, operation time with
constant load and rest period. The rest period
allows the machine to cool down so that thermal
equilibrium is not reached. [Example, the relative
on-time at S4-25% or S4-50% is limited to 25% and
50% respectively. ----- 15 Rev0]
3.1.6. Space Heater
Condensation in the actuator is possible due to wide fluctuation of the ambient temperature. The
heater integrated in the control unit prevents from this in general.
Ceramic housing with thermostat to prevent over heating with 60℃ set temperature.
