1. Safety Instructions
ATTENTION!
Any non-compliance with these safety precautions may result in severe damage to property and health!.
ATTENTION!
These Operating Instructions explain the installation, bringing into service, and operation of the type BS
805.0x amplifier. It is assumed that every action is taken by qualified staff only who have adequate
knowledge in the fields of measuring and control engineering.
The equipment must be installed and attached under adherence to of the current DIN and VDE
standards.
ATTENTION!
The type BS 805.01 Strain-Gauge amplifier has been designed to the purpose of amplifying the output
signals of sensors with metal-foil strain gauges, preferably force transducers.
The type BS 805.02 has been designed to the purpose of amplifying the output signals of sensors with
standard signal 4-20mA, preferably force transducers.
Any other application is regarded contrary to intended usage.
The BS 805.0x may not be used as exclusive means for the prevention of dangerous conditions at
machines and plants.
Make sure that any erroneous setting or malfunction of the unit or its break-down cannot cause damage
or be a risk to the staff or other persons.

6. Information on Performance-Level PLc in accordance with DIN EN 13849-1
6.1. Classification of Type Series “Switching Amplifier BS 805”
The Switching Amplifier BS805 can be classified in the Performance-Level PLc in accordance with the set of
standards governing Safety Relevant Control Systems DIN EN 13849-1.
This then covers hazards as shown in the hazard graphs below recommended for safety-relevant control systems in
conjunction with the Performance-Level PLc and SK1 Category.
Severity of injury (S)
S1 Slight injury (usually temporary)
S2 Severe injury (usually irreversible),
including death
Frequency and/or duration of exposure to
hazard (F)
F1 ... Seldom to quite often and/or short
duration of exposure
F2 ... Frequent to permanent and/or short
duration of exposure
Possibility of preventing the hazard (P)
P1 ... Possible under certain conditions
P2 ... Hardly possible
6.2. Error detection in operation with a connected sensor
The Switching Amplifier BS805 identifies the following errors:
Sensor monitoring
- Wire breakage, also on single core of sensor cable.
- Short circuit on any number of cores of sensor cable.
- “Unsafe” connection of individual cores.
Internal monitoring
- Failure of operating voltage
- Failure of sensor power supply
The BS 805 is responding to an error with:
- Relay SP1 and SP2 fall (to drop out)
- LED U78 blinking
- Output signal is 2mA
