Operation
Referencing
Enter the reference value for referencing via the output double word DataOUT1 [}33] and set bits CB1.0
[}33] (EnLatchC) and CB1.2 [}33] (SetCnt) in the control byte. The reference value is now adopted by the
counter on a rising edge at input C.
Measuring the workpiece
At the beginning of the measurement the filter value is preset in the filter register R0 [}45].
Then set the release bit CB1.1 [}33] (EnMeas) in the control byte. If a plate has been successfully
measured, the terminal sets bit SB1.1 [}34] (MeasDone) in the status byte.
The measurement begins on an appropriate edge. If the level already exists, only the position of the end of
the board is determined. The start of the measurement is then taken as the start of the board.
Post-forming sawing
The output has a rise time of 10 µs and a 40 µs delay due to the optocoupler.

Mounting and wiring
4 Mounting and wiring
4.1 Installation on mounting rails
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation,
disassembly or wiring of the Bus Terminals!
Assembly
Fig.4: Attaching on mounting rail
The Bus Coupler and Bus Terminals are attached to commercially available 35mm mounting rails (DIN rails
according to EN60715) by applying slight pressure:
1. First attach the Fieldbus Coupler to the mounting rail.
2. The Bus Terminals are now attached on the right-hand side of the Fieldbus Coupler. Join the
components with tongue and groove and push the terminals against the mounting rail, until the lock
clicks onto the mounting rail.
If the Terminals are clipped onto the mounting rail first and then pushed together without tongue and
groove, the connection will not be operational! When correctly assembled, no significant gap should
be visible between the housings.
Note
Fixing of mounting rails
The locking mechanism of the terminals and couplers extends to the profile of the mounting
rail. At the installation, the locking mechanism of the components must not come into conflict with the fixing bolts of the mounting rail. To mount the mounting rails with a height of
7.5mm under the terminals and couplers, you should use flat mounting connections (e.g.
countersunk screws or blind rivets).
KL5151/KS5151, KL5152/KS515212 Version: 2.0.0
Mounting and wiring
Disassembly
Fig.5: 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 1cm 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.
2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower grooved
housing surfaces and pull the terminal out of the bus terminal block.
Connections within a bus terminal block
The electric connections between the Bus Coupler and the Bus Terminals are automatically realized by
joining the components:
• The six spring contacts of the K-Bus/E-Bus deal with the transfer of the data and the supply of the Bus
Terminal electronics.
• The power contacts deal with the supply for the field electronics and thus represent a supply rail within
the bus terminal block. The power contacts are supplied via terminals on the Bus Coupler (up to 24V)
or for higher voltages via power feed terminals.
Note
Power Contacts
During the design of a bus terminal block, the pin assignment of the individual Bus Terminals must be taken account of, since some types (e.g. analog Bus Terminals or digital 4channel Bus Terminals) do not or not fully loop through the power contacts. Power Feed
Terminals (KL91xx, KL92xx or EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail.
PE power contact
The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates first
when plugging together, and can ground short-circuit currents of up to 125A.
KL5151/KS5151, KL5152/KS5152 13Version: 2.0.0
Mounting and wiring
Fig.6: Power contact on left side
Attention
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 230V). For insulation testing, disconnect the PE
supply line at the Bus Coupler or the Power Feed Terminal! In order to decouple further
feed points for testing, these Power Feed Terminals can be released and pulled at least
10mm from the group of terminals.
WARNING
Risk of electric shock!
The PE power contact must not be used for other potentials!
4.2 Connection system
WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation,
disassembly or wiring of the Bus Terminals!
Overview
The Bus Terminal system offers different connection options for optimum adaptation to the respective
application:
• The terminals of KLxxxx and ELxxxx series with standard wiring include electronics and connection
level in a single enclosure.
• The terminals of KSxxxx and ESxxxx 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.
KL5151/KS5151, KL5152/KS515214 Version: 2.0.0
Mounting and wiring
Standard wiring
Fig.7: Standard wiring
The terminals of KLxxxx and ELxxxx series have been tried and tested for years.
They feature integrated screwless spring force technology for fast and simple assembly.
Pluggable wiring
Fig.8: Pluggable wiring
The terminals of KSxxxx and ESxxxx series feature a pluggable connection level.
The assembly and wiring procedure for the KS series is the same as for the KLxxxx and ELxxxx series.
The KS/ES series terminals enable the complete wiring to be removed as a plug connector from the top of
the housing for servicing.
The lower section can be removed from the terminal block by pulling the unlocking tab.
Insert the new component and plug in the connector with the wiring. This reduces the installation time and
eliminates the risk of wires being mixed up.
The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3
mm. The maximum height of the terminal remains unchanged.
A tab for strain relief of the cable simplifies assembly in many applications and prevents tangling of individual
connection wires when the connector is removed.
Conductor cross sections between 0.08mm2 and 2.5mm2 can continue to be used with the proven spring
force technology.
The overview and nomenclature of the product names for KSxxxx and ESxxxx series has been retained as
known from KLxxxx and ELxxxx series.
High Density Terminals (HD Terminals)
Fig.9: High Density Terminals
The Bus Terminals from these series with 16 connection points are distinguished by a particularly compact
design, as the packaging density is twice as large as that of the standard 12mm Bus Terminals. Massive
conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal
point without tools.

Note
Ultrasonically “bonded" conductors
It is also possible to connect the Standard and High Density Terminals with ultrasonically
"bonded" (ultrasonically welded) conductors. In this case, please note the tables concern-
ing the wire-size width [}16] below!

Fig.10: Mounting a cable on a terminal connection
Up to eight connections enable the connection of solid or finely stranded cables to the Bus Terminals. The
terminals are implemented in spring force technology. Connect the cables as follows:
1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square opening
above the terminal.
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal closes automatically when the pressure is released, holding the wire securely and
permanently.
