Setting Of Volume And Signal Tone; Iso 9001; Recycling; Safety Instructions - Eaton DEV20 Technical Manual

Setting of volume and signal tone

To set volume and signal tones the cover of the housing has to be removed. The electrical plug connection to the bottom
section can be cut. In the upper section the setting can be carried out at the 12 slide switches. The sounder dEV20
disposes of two signal levels. The signal tone for the first level is adjusted with the slide switches 1-5 (S0) according to
the signal choice list. The signal tone for the second signal level is adjusted with the slide switches 6-10 (S1).
The volume is set by the slide switches 11 and 12 (see table).
The shift from the first to the second signal level in case of devices direct tension is realized by additional application of
a positive operation voltage on clamp 3. In case of alternating tension the shift is made by additional application of the
phase (L1) of the operation voltage on clamp 3.
After the completion of the setting the electrical connection to the bottom section has to be re-established and the upper
section has to be fixed with the respective screws on the bottom section. (CAUTION! Don't damage the gap of the
joint.) The locking torque of the screws is: 1.2 ... 1.5 Nm
