Outdoor use
If you would like to use the limit switch boxes outdoors (outdoor installation), the limit switch boxes should be equipped with an Ex e
pressure compensating element. The pressure compensating element prevents water condensation in the housing in the event of outdoor
temperature fluctuations. Please check whether or not there is a pressure compensating element. If not, you have to order respective limit
switch boxes. In this case, the addition to the item number is “-DAE”.

Maintenance
The limit switch boxes for ATEX areas may never be opened during operation or in an existing explosive atmosphere. Opening them can
cause an explosion. Therefore, maintenance work is only possible outside of the Ex area.
With the long-term outdoor use of the switch boxes and with extremely high or low ambient temperatures, the sealings inside of the cover
and on the shaft can become porous. A safe use can only be guaranteed with a leak-proof housing. Sealings need to be replaced as soon as
they are worn out, but no later than after 5 years. The necessary sealings can be offered from EUROTEC.
The cover screws can loosen in the event of strong vibrations or temperature fluctuations. Retighten the screws every two years. Any other
modifications to the device are prohibited!

Malfunctions
In the event of malfunctions, please check the lines, line connectors and the position of the cams. Furthermore, please check whether
condensation water has accumulated in the housing and whether the valve and the actuator are functioning properly. Rectify any possible
errors. If this does not rectify the malfunction, disconnect the housing from the power supply voltage and contact one of the manufacturer’s
authorised and trained specialists.
