1.4 General functional description
The IV20 pulse distributor is used in conjunction with an incremental encoder to extend the signal path in complex systems.
The device enables the distribution of the signals K1, /K1 and K2, /K2 as well as K0, /K0 of a single encoder to six outputs, each with different output potentials.
To cover a wide range of applications, a level conversion from 5 V differential, 11…30 V push-pull, opencollector or open-emitter at the input to 5 V TTL differential or 11…30 V push-pull at the output.
All adjustable voltage levels are output via the same contacts. As the device has a universal design, the respective connection levels must be coded in the corresponding mating connector using wire jumpers.
Pull-up or pull-down resistors are available on the input side. They are activated by a wire jumper to the corresponding auxiliary voltage on the connector. The basic configuration of the input is designed for differential 5 V signals (RS 422). If single-channel signals with levels from 11 V are to be processed, the reverse potential of the differential input must also be formed via corresponding coding in the connector.

Installation / Preparation for commissioning
6 Installation / Preparation for commissioning
6.1 General Rules
· The shielding effect of cables must also be guaranteed after installation (bending radii/tensile strength!) and after plug changes. If in doubt, use a more flexible cable with a higher load capacity.
· To connect the device, only use connectors that ensure good contact between the cable shield and the connector housing. The cable shield must be connected to the connector housing over a large area.
· When wiring the drive/motor, it is recommended to use a 5-core cable with a PE conductor separate from the N conductor (so-called TN network). This largely prevents potential equalization currents and the coupling of interference.
· Equipotential bonding measures must be provided for the entire processing chain of the system. In particular, equalizing currents due to potential differences across the shield to the device must be avoided.
· A shielded and stranded data cable must be used in order to achieve a high immunity of the system to electromagnetic interference. If possible, the shield should be connected to protective earth on both sides with good conductivity via large-surface shield clamps. The shield should only be earthed at one end in the switch cabinet if the machine earth is subject to high levels of interference in relation to the switch cabinet earth.
· Separate routing of power and signal cables. The national safety and installation guidelines for data and power cables must be observed during installation.
· No spur lines · Separate or isolate the device from possible interference transmitters. · Observe the manufacturer’s instructions when installing inverters, shield the power cables
between the frequency inverter and motor. · Adequate dimensioning of the power supply. · To ensure safe and trouble-free operation, the relevant standards and directives must be
observed. In particular, the EMC Directive as well as the shielding and earthing directives in their current versions must be observed. · It is recommended that a visual inspection with a report is carried out after the installation work has been completed. · It is recommended to carry out a visual inspection with a report after completion of the installation work.
6.2 Galvanic Isolation
With long supply lines for the incremental input data, a potential shift is to be expected for the incremental signal transmitter and IV20, even with the same power supply unit. It may then not be possible to evaluate the incremental data reliably. For this reason, the power supply of the IV20 is internally galvanically isolated from the signal ground. This means that no interfering equalizing current can flow.
The user must carry a reference potential from the device that supplies the incremental data in addition to the signal lines.
