1241055 & 1241056 is intended for installation within control panels. Make sure that the device is used only for
intended purpose. The shielding must be grounded on the instrument side. During an installation, all of the
cables that are connected to the device must be free of electrical power. The device must be protected against
inadmissible humidity, vibrations, severe soiling. Make sure that the operation temperature is not exceeded.
All input and output lines that are not connected to the supply network must be laid out as shielded and twisted cables.
These cables should not be close to the power cables or components. The installation and electrical connections must
be carried out by a qualified staff and must be according to the relevant locally applicable regulations.

If key is pressed and held 0.6 seconds, the value of the
selected parameter increases rapidly. If waited enough,the
value increases a hundred at each step. After 1 second,
following the release of the key, initial increasing condition is
returned. The same procedure is valid for the decrementing.
