6.5 Operating mode on standard operation/ limit switch allocation
The actuator moves from the "Closed" position to the "Open" position by applying live
voltage to the nominally open "S1" terminal. By applying live voltage to the normally
closed "S2" terminal, the actuator will move from the "Open" position to the "Closed"
position. Remember only to apply live voltage to one terminal at a time. The final
positions are defined by the two limit switches S1 and S2.

6.5.1 Overload protection
The supply unit of the EA21/31/42 has an overload protection that protects the direct
current motor and the supply board from overheating. The overload protection is
activated as soon as the load exceeds the torque range. The actuator continues to run
as soon as the load is within the torque range and the temperature has gone down.
6.5.2 Safety position
In case of power failure, the actuator stays in its current position. If the actuator is
fitted with the accessory "fail-safe return unit“, it can automatically return to a safety
position after a power failure.

In addition to this manual, please also follow the specifications of the valve
manufacturer.
Before assembling actuator on valve, see assembly instructions for the
intermediate parts
Before installation, compare technical data of the actuator with the control and the
valve. Only install actuator if the data matches.
Before installation, check plugs and terminals for possible damage.
Make sure that no damaged parts are used.
Have installation and assembly only carried out by specialist staff.
If actuator for system requires the protection class IP67:
- Use cable gland connections.
- Mount actuator vertically.
If device is directly controlled:
- Fit a circuit-breaker on site.
- Do not connect grounding conductor.
20
Page 21
Electrical actuators type EA 11/ 21/ 31/ 42 Installation
Requirements
- Cross section of the power lines max. 1.5 mm2.
- Fuse size: > 6 A.
Ensure that actuator is only connected to voltages that meet the requirements on
a protective extra low voltage circuit (PELV).
Connect actuator, see Section 7.2 Connection diagram
To prevent water getting into actuator, ensure that cable plug is not pointing
upwards.
If temperatures under -10°C plus water condensation are to be expected:
fit "heating element“ accessory.
7.4 Adjusting limit switches
The two end positions in the actuator have been factory set to 90°. A
readjustment may be required after assembly by the customer.
Disconnect actuator from voltage.
Open cover. To do so, loosen the 4 screws.
Position both switching cams S1 and S2 (Fig. see Section 6.5) in such a way to each
other that the angle of rotation is less than 90°.
Connect actuator to voltage and let it rotate until a limit switch is activated.
Adjust limit switch until the desired end position is set.
Repeat procedure as required until desired end positions are set.
Fit cover and fasten with the 4 screws.

8 Operation
WARNING
Too high current peaks the first time the actuator is switched on by
charging the mains capacitor!
Danger of injury and/or malfunction.
Connect and operate actuator as per connection diagram, see Section 7.2
Connection diagram
Before commissioning the system, carry out a functional test of the product.
8.1 Functional test
WARNING
Working with actuator cover removed!
Danger of injury and/or damage to property.
Disconnect connections of the feed and control voltage.
Only carry out adjustments on live parts with specially insulated tools.
Before actuator is connected to mains voltage:
Make sure that main voltage matches details on type label
Make sure that actuator is connected properly
Check fuse: > 6 A
Check that valve position matches position indicator of the actuator.
Make sure that actuator and valve are connected correctly and tightly.
Using the manual emergency override, the actuator can also open or close the
valve without mains voltage, see Section 10.1
8.2 Using manual emergency override
The integrated manual emergency override is used to move the actuator manually to
another position. The integrated manual emergency override allows the actuator to
continue operating temporarily if there is no power.
if the actuator constantly or frequently fails: change actuator.
