3.1.3. Duty Cycle *
1
Duty cycle data were indicated Clause 3.1.1 Standard Technical Data
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
The duty is a sequence of identical cyc
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.
3.1.4. Manual override
3.1.5. Lubrication
HQ-004 electric actuator is a totally enclosed unit with permanent lubricated gear train
(Moly EP Grease). Once installed, further lubrication should not be required. However,
periodic preventative maintenance will extend the operating life of the actuator.
