Guidelines and standards Aris actuators of the ExTensor series are partly completed machinery in the sense of the European Directive 2006/42/EC. The Decla ration of Incorporation for the devices can be found at the end of this operating manual. During the development, production and...
Functions and application areas (Intended use) ARIS actuators of the ExTensor series are designed exclusively for industrial use in potentially explosive areas according to their labeling. They are used to actuate control and shut-off devices ( aps, valves, taps, sliders, dosing pumps, etc.).
Housing entries (tapped holes) 3.2.1 Cable and wire entries Features ARIS ExTensor 3x M25x1.5 tapped holes When delivered, the actuators are provided with a transport protection (protective sticker), which covers the threaded holes of the cable and line entries. This must be removed and replaced with suitable, approved entries or plugs. The entries/blind plugs used must correspond to the ignition protection types of the drive.
- The ATEX/IECEx approval of the device becomes void in the event of non-compliance or misuse. Suitable products (cable entries, blind plugs) are available as accessories from ARIS, tailored to the ATEX/IECEx products. If requi- red, these are loosely enclosed with the drive. The delivery is always unassembled.
Actions must be taken to avoid the formation of condensation (e.g. in the event of temperature uctuations) Packaging ARIS drives are protected by special cardboard packaging for transport from the factory. Unpacking in the Ex area is not permitted as the materials could become electrostatically charged.
(e.g. by dropping it);no ropes, hooks, etc. attach directly to the drive • permanent overloading and blocking of the drive leads to damage to the drive • only use original ARIS spare parts Consider prior to attachment of couplings: • Do not turn actuator shafts by force;...
This can be avoided by loosening a cable/line entry or blind plug so that air can ow through it. CAUTION DANGER! The lead-in must be professionally closed again before commissioning or for further storage. Danger! Pressure proof encapsulation ExTensor...
To create the type of protection, ameproof gaps with narrow cylindrical ts are installed. Gap surfaces must not be damaged. Damaged surfaces must not be machined or repaired in any other way - contact ARIS Service. Cover and housing parts must be handled with care.

In doing so, observe the procedure and instructions for opening and connecting the drive in these operating instructions. De-energize the drive before opening. Make sure that there is no explosive atmosphere in the area when working on the drive. Also, before performing a reset, make sure that the causes of the elevated temperature have been eliminated.

Left and right end positions can be interchanged. The assignment of the turning direction of the inputs 2/3 and the buttons LI/RE do not change. The end positions must be 28° apart due to technical reasons. If the difference range is too small, the actuator will prompt "Error Code 51". ExTensor...

- mechanichal poti, terminals ... ? Maintenance and service ARIS actuators of the ExTensor series have permanent lubrication and are basically maintenance-free. We recommend carrying out a function test and a visual inspection once a year. Repairs: No repairs or mechanical processing of any kind may be carried out on the gap surfaces of the ameproof gaps. In particular, the cover/housing gap surfaces must not be changed.
