Page 5: Preliminary Information
This guide is designed to provide the most complete information the operator needs to correctly and safely install and operate the IF31 converter and interpolator for 1Vpp Sine/Cosine encoders. IF31 is an encoder interface designed to convert the signals provided by 1Vpp Sine/Cosine encoders into incremental quadrature signals (AB0 /AB0 digital signals). - Page 6 All settings are made by means of two 12 pin DIL switches that are mounted on the top and on the bottom of the housing respectively. WARNING The power supply must be switched off before setting the DIL switches. Changes in the DIL switch positions will become active only after the unit is switched OFF and then ON again.

Page 27: Miscellaneous Hints
IF31 converter does not provide potential separation, i.e. the GND of the unit is also the GND of the sensor at the same time. Therefore, it is important to ensure safe conditions of the earthing installation and to prevent earth loops and balance currents flowing through the unit. - Page 28 Document release Release date Description 17.06.2024 First issue Lika Electronic Via S.
