3.1.4 Duty Cycle
Duty cycle rating according IEC60034-1 S4. See table in paragraph 3.1.2 for rating figures.
Exceeding the actuator
’
s rated duty cycle may cause thermal overload
.
Intermittent duty S4
The duty is a sequence of identical cycles 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. The relative on-time at S4-25% or S4-50% is limited to 25% and 50% respectively.
3.1.5 Space Heater
Condensation in the actuator is possible due to wide fluctuation of the ambient temperature. The
heater integrated in the control unit prevents this in general.

3.1.6 Hand Wheel and Declutching
ELA-series actuators are provided with a declutchable manual override
system.
•
In order to manually operate the actuator, pull the manual
override lever towards the hand-wheel until. It will remain in position.
•
Turn the hand-wheel until the valve reaches the required position.
•
Turn clockwise to close and counter-clockwise to open.
Note: The manual override lever returns automatically to auto-position
when the actuator is operated electrically.
