Product overview Basic function principles The analog input terminals KL3011 and KL3012 process signals in the range from 0 mA to 20 mA KL3021 and KL3022 process signals in the range from 4 mA to 20 mA with 12-bit resolution (4095 steps). The terminal inputs are differential inputs with common ground. Due to the differential inputs, the terminals are particularly suitable for ground-free measurements in current loops.

Mounting and wiring Assembly Fig. 5: Attaching on mounting rail The bus coupler and bus terminals are attached to commercially available 35 mm mounting rails (DIN rails according to EN 60715) by applying slight pressure: 1. First attach the fieldbus coupler to the mounting rail. 2.
Mounting and wiring Disassembly Fig. 6: Disassembling of terminal Each terminal is secured by a lock on the mounting rail, which must be released for disassembly: 1. Pull the terminal by its orange-colored lugs approximately 1 cm away from the mounting rail. In doing so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of the bus terminal block easily without excessive force.
Mounting and wiring Fig. 7: Power contact on left side NOTE Possible damage of the device Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g. disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230 V).

Mounting and wiring • The terminals of ESxxxx and KSxxxx series feature a pluggable connection level and enable steady wiring while replacing. • The High Density Terminals (HD Terminals) include electronics and connection level in a single enclosure and have advanced packaging density. Standard wiring (ELxxxx / KLxxxx) Fig. 8: Standard wiring The terminals of ELxxxx and KLxxxx series have been tried and tested for years.
Mounting and wiring The Bus Terminals from these series with 16 terminal points are distinguished by a particularly compact design, as the packaging density is twice as large as that of the standard 12 mm Bus Terminals. Massive conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal point without tools.

Configuration Software KS2000 Configuration Software KS2000 KS2000 - Introduction The KS2000 configuration software permits configuration, commissioning and parameterization of bus couplers, of the affiliated bus terminals and of Fieldbus Box Modules. The connection between bus coupler / Fieldbus Box Module and the PC is established by means of the serial configuration cable or the fieldbus. Fig. 14: KS2000 configuration software Configuration You can configure the Fieldbus stations with the Configuration Software KS2000 offline.
Configuration Software KS2000 Commissioning The KS2000 software facilitates commissioning of machine components or their fieldbus stations: Configured settings can be transferred to the fieldbus modules by means of a download. After a login to the terminal station, it is possible to define settings in couplers, terminals and Fieldbus Box modules directly online. The same high-level dialogs and register access are available for this purpose as in the configuration phase.

Access from the user program Access from the user program Terminal configuration The terminal can be configured and parameterized via the internal register structure. Each terminal channel is mapped in the Bus Coupler. Mapping of the terminal data in the Bus Coupler memory may differ, depending on the Bus Coupler type and the set mapping configuration (e.g. Motorola/Intel format, word alignment etc.).
Access from the user program • KL3012 and KL3022: 4 bytes of input data Parameterization via the fieldbus is not possible. If the control and status byte is to be used, the KS2000 configuration software is required. Fig. 20: Mapping in the Interbus coupler – example for KL3012 and KL3022 Other Bus Couplers and further information Further information about the mapping configuration of Bus Couplers can be found in the Appendix of the respective Bus Coupler manual under Master configuration.
