Safety Instructions
Personnel Qualification
This description is only intended for the use of trained specialists in control
and automation engineering who are familiar with the applicable national
standards. It is essential that the following notes and explanations are
followed when installing and commissioning these components.
Liability Conditions
The responsible staff must ensure that the application or use of the
products described satisfy all the requirements for safety, including all the
relevant laws, regulations, guidelines and standards.
The documentation has been prepared with care. The products described
are, however, constantly under development. For that reason the
documentation is not in every case checked for consistency with
performance data, standards or other characteristics. None of the
statements of this manual represents a guarantee (Garantie) in the
meaning of § 443 BGB of the German Civil Code or a statement about the
contractually expected fitness for a particular purpose in the meaning of
§ 434 par. 1 sentence 1 BGB. In the event that it contains technical or
editorial errors, we retain the right to make alterations at any time and
without warning. No claims for the modification of products that have
already been supplied may be made on the basis of the data, diagrams
and descriptions in this documentation.
State at Delivery
All the components are supplied in particular hardware and software
configurations appropriate for the application. Modifications to hardware or
software configurations other than those described in the documentation
are not permitted, and nullify the liability of Elektro BECKHOFF GmbH.

Functional description
The analog input terminals
- KL304x process signals in the range between 0 and 20 mA
- KL305x process signals in the range between 4 and 20 mA
with a resolution of 12 bits (4095 increments). They can supply the sensors
from voltage fed in via the power contacts. The power contacts can
optionally be supplied via the standard supply or via a feed terminal with
electrical isolation.
Process data output format In the delivery state the process data are shown in two's complement form
(integer -1 corresponds to 0xFFFF). Other display types can be selected
via the feature register (e.g. sign/amount representation, Siemens output
format).

LED display The LEDs indicate the operating state of the associated terminal channels.
Green LED: RUN (not applicable for KL3044 and KL3054)
• On: normal operation
• Off: Watchdog-timer overflow has occurred. If no process data is
transmitted to the bus coupler for 100 ms, the green LEDs go out.
Red LED: ERROR
• On: The limit stop of the A/D converter has been reached. The
current is greater than 21.5 mA.
• Off: normal operation

Process data The process data that are transferred to the Bus Coupler are calculated
using the following equations:
X_adc: Output values of the A/D converter
Y_aus: Process data to PLC
B_a,A_a: Manufacturer gain and offset compensation (R17, R18)
B_h,A_h: Manufacturer scaling (R19, R20)
B_w,A_w: User scaling (R33, R34)
a) Neither user nor manufacturer scaling are active:
Y_a = (B_a + X_adc) * A_a (1.0)
Y_aus = Y_a
b) Manufacturer scaling active (factory setting):
Y_1 = B_h + A_h * Y_a (1.1)
Y_aus = Y_1
c) User scaling active:
Y_2 =B_w + A_w * Y_a (1.2)
Y_aus = Y_2
d) Manufacturer and user scaling active:
Y_1 = B_h + A_h * Y_a (1.3)
Y_2 = B_w + A_w * Y_1 (1.4)
Y_aus = Y_2
The equations of the straight line are activated via register R32.
