1. General description
The "LS 804 Load Switch” is a configurable switching device.
Based on DIN ISO 13849, the design and architecture of the LS 804 load switch unite to bring
about a high level of safety integrity. The appliance meets PerformanceLevel PL c.
Up to a total of four sensors can be linked up to the device. The LS 804.01 is capable of processing
sensors with a strain-gauge signal in mV/V, whereas the LS 804.02 processes sensors with a standard
signal of 4-20 mA. Sensors processing a standard signal of 4-20 mA can be fed from the LS 804 applying
24 V DC.
The mode of operation on the device is set by configuration via a web browser in addition to individual
setting and adjustment on the keypad. Depending on the number and type of the connected load sensors,
individual, cumulative, differential and partial loads can be monitored.
Outputting of the freely parameterisable load shut-off points takes place via six relays ("K1" to "K6") with
N/O contacts. Allocation of the relays to the load signals is freely configurable. In addition, the device
incorporates two error relay outputs "Error1" and "Error2". These error relays are not freely programmable
and generate a “0” status in the event of a system error occurring. The use of force-guided relays on the
SLS 801 serves to ensure maximum system safety.
Two analogue outputs and two digital interfaces are provided for further application of the load signals on
overriding systems.
2. Functional description
CAUTION! Any operating processes or adjustments performed on the keypad of the LS 804 via
the web browser as well as changes made to the limit-set function by means of switching inputs
IN1 to IN8 will render the switching function inoperative for the duration of this work and the
resetting phase as well as for a few seconds afterwards.

Monitoring not only takes place of output relays "K1" to "K6" and error relays "Error1" and "Error2”, but
also of the load sensors with respect to cable rupture and short-circuiting. In the event of system errors
occurring, the error relays will switch off. A sensor error on any input does not automatically lead to loss
of function on the overall system. As a result of this functionality feature, a high level of safety is attained
along with maximum possible availability.
The LS804 is designed with several peripheral interfaces.
- The two analogue outputs 0-10 V / 4-20 mA for sensors a to d or selected total formation.
- Connection: LAN (RJ-45)
- Connection X1: CAN
- Connection X2: RS485 / optional RS232

4.2. Voltage supply 24 V DC
The operating voltage is 18-36 V DC, this being based on a maximum power consumption of 15 VA.
Operational readiness is indicated by means of an LED next to the 24 V AC connections.
Conductors of up to 1.5 mm2 can be connected up to terminal blocks 1 to 6.
After the operating voltage has been applied, the green LED “Power” indicator will light up next to terminal
1 as well as the “Run” LED.

4.3.2. LS 804.02
The LS 804.02 is designed for DMS sensors having an integrated or external DMS amplifier with a
standard signal output 4-20mA.
The LS 804.02 feeds the amplifiers with 24V DC, max. 25 mA. The input signal range without error
message extends from 2 mA to 22 mA.
The "0V" connections of the respective sensors are bridged internally. If sensors with three conductors –
"UB", "OUT" and "OV" – are available, connections 32, 37, 42 und 47 must be left free.

4.4. Switching inputs IN1 to IN16
Sixteen optocoupler inputs are arranged in four groups each group being made up of four inputs. Limit
sets can be accessed to by means of inputs IN1 to IN8.
A static signal on the relevant input provides access to the corresponding limit set: Via IN1, set “1” is
defined as the current set. If no signal is present, the LS 804 will operate with the limit set last displayed
in Chapter 6.4 Limits (K1 to K6). If, by accident, more than one input is occupied by a signal, the LS 804
will utilise that input having the lowest number.
For the load spectrum recorder, inputs IN13 and IN16 are employed for switching the “Raise/Lower”
signals (signals a to d). A signal applied to input IN12 generates the RESET function on the device in the
event of an error occurring; also refer to Chapter 7 Maintenance / Error messages.
