1.3. Installation The device is only allowed to be installed and operated within the permissible temperature range. Please ensure an adequate ventilation and avoid all direct contact between the device and hot or aggressive gases and liquids. Before installation or maintenance, the unit must be disconnected from all voltage-sources. Further it must be ensured that no danger can arise by touching the disconnected voltagesources.

2. Introduction This universal level converter, on the input side, can accept single channel and quadrature encoder signals with either RS422 format or TTL level or HTL (10-30V) level. Where the signal provides direction information, the direction may be defined by either an A/B-90° phase displacement, or by a static direction signal.

4. Switch settings The front DIL switches require a few settings depending on the signal levels and the mode of indicating the direction on inputs and outputs 4.1. Input characteristics You can set the desired input characteristics by switch DIL2, positions 6, 7 and 8 0=OFF 1=ON 8 7 DIL2 6 1 (Z) 1 (B) 1 (A) 0 (Z) 0 (B) 0 (A) 5 4 3 2 1 Single-ended input: Only signals A, B and Z are connected, the inverted inputs /A, /B, /Z remain unconnected.

4.3. Definition of the direction of rotation The unit is designed to evaluate quadrature direction information (A/B, 2x90°) and static direction information as well. Furthermore it can convert the direction information from one format to the respective other format. Positions 3, 4 and 5 of switch DIL2 provide individual selection for input and output.
