Description of operation

Depending on the type of connection (see connection diagram), the actuator can be used as a contin­uous (0...10 V or 4...20 mA), 2-point (OPEN/CLOSE) or a 3-point actuator (OPEN/STOP/CLOSE).
The positioning time of the actuator can be set with the S1 switches according to the respective re­quirements. Using switch S2, the direction of operation can be changed.
In the end positions (valve limit stop or when the maximum stroke is reached) or upon overload, the
electronic motor cut-off (no limit switch) responds and turns off the motor.
The external crank handle enables manual positional setting. After the crank handle is folded back,
the actuator moves to the target position again (without initialisation). When the crank handle is folded
out, the actuator remains in this position.

Intended use

This product is only suitable for the purpose intended by the manufacturer, as described in the “De­scription of operation” section.
All related product regulations must also be adhered to. Changing or converting the product is not ad­missible.

Engineering and fitting notes

The concept of a brushless DC motor/electronics ensures electrical parallel operation of up to five ac­tuators of the same type.
The valve is mounted directly on the actuator and fixed with screws (no further adjustments are re­quired). The actuator is connected with the valve spindle automatically. As delivered ex works, the ac­tuator spindle is in the middle position.
As delivered ex works, the actuator spindle is in the middle position.
Condensate, dripping water, etc. must be prevented from entering the actuator along the valve spin­dle.
The housing contains two break-out cable inlets for two metric plastic cable glands M20×1.5, which
are broken out automatically when the cable inlet is screwed in.
If the cable resistance is > 1.5 Ω, the ground should be separated from the power supply and the sig­nal if possible.
The cross-section of the power cable must be selected based on the cable length and the number of

actuators. With five parallel actuators and a cable length of 50 m, a cable cross-section of 1.5 mm

2

and a line resistance of > 1.5 Ω must be used (power consumption of the actuator × 5).
According to building installation regulations, the lines must be protected from overload or short cir­cuit.

)

Note for UL and CSA applications:
In the United States, the installed lines and cross-sections which are to be connected by the customer
must comply with the requirements of NFP

A70 (NEC), and in Canada they must comply with the require-

ments of the standard C22.1-12 (CE Code).

The coding switches and the SLC interface for CASE Drives are accessible via an opening in the con­nection area of the actuator. Conversion and operation is possible while the actuator is energised.
