Device description
Limit switch boxes serve to provide feedback and control the position of industrial valves, which are activated using pneumatic actuators.
The shaft of the limit switch box has a positive connection with the shaft of the actuator and is rotated with the rotational movement of the
actuator. The actuating cams attached to the shaft, activate the installed sensors, which support the electronic signal transmission.
The wave Ex de t limit switch boxes are equipped with 1 to 3 mechanical Ex d switches depending on the model.

Intended use
The wave Ex de t limit switch box from the EUROTEC Antriebszubehör GmbH is intended for use in the explosive area of zones 1 and 2 with
gases, mists or vapours and zone 21 and 22 with combustible dust.

It’s approved for use in the following ambient temperature ranges:
Vestamid:
-20°C...+40°C
Aluminium:
-55°C/-20°C...+60°C
The approved ambient temperature varies, depending on the sealing compound and the installed switch type. You can find the ambient
temperature in the corresponding data sheet and on the product label. A lower temperature range down to -55°C applies to limit switch
boxes, which are made of components, that are at least suitable for this temperature.

Labeling
The labeling on the housing is shown in Fig. 1 and varies depending on the installed switch type. You can find the number of the indicated
responsible office for the QM system and the serial number below the CE mark. It consists of the year of manufacture and the respective
order number.

The housings are not intended to be used as stepladders, to climb into the system. This can lead to damaging
them and having a negative effect on their function. If the housing is damaged, water as well as dirt and
combustible material can accumulate inside the housing. This can lead to a short circuit. Furthermore, the
device can heat up severely due to the accumulation and can cause an explosion.
4.
Special Conditions
The limit switch boxes type EV…ED and EV…K2D have been tested with reduced impact energy and must be protected against mechanical
hazards. The special conditions specified in the corresponding operation instructions must be observed for the Ex components used. This
applies in particular to cable glands and connectors.
