1.4 Terms and definitions
commissioning Test on an item carried out on site, to prove that it is
correctly installed and can operate correctly
(IEC 60050-151-16-24).
damped One or two sensor systems of a wheel sensor indi-
cate an occupancy (generally in the case of travers-
ing by a train wheel and/or when damped by a testing
plate).
digital filtering time The digital filtering time is the time for which the
sensor current must fall below the trigger level or ex-
ceed the tripping level, before the sensor system is
considered to be “damped”or “not damped”.
direction pulse duration The direction pulse duration is the time for which the
direction pulse applies at the output. The direction
pulse duration is retriggerable.
interference voltage Voltage that may occur at the ends of outdoor
equipment cables as a result of inductive or capaci-
tive influences to earth.
maintenance, corrective The maintenance carried out after fault recognition
and intended to put an item into a state in which it
can perform a required function
(IEC 60050-191-07-08).
Synonym: repair
maintenance, preventive The maintenance carried out at predetermined inter-
vals or according to prescribed criteria and intended
to reduce the probability of failure or the degradation
of the functioning of an item (IEC 60050-191-07-07).
Synonym: servicing
maintenance, servicing The maintenance carried out at predetermined inter-
vals or according to prescribed criteria and intended
to reduce the probability of failure or the degradation
of the functioning of an item (IEC 60050-191-07-07).

normal operating sensor current level The normal operating sensor current level corre-
sponds to the sensor current at the time of a suc-
cessfully carried out adjustment and is to be equated
with 100 % (adjustment value).
normal operating sensor current (RSR110) The sensor current is referred to as “normal operat-
ing sensor current” if the wheel sensor is correctly
mounted on the rail, successfully adjusted and not
damped.
overcurrent level If the sensor current exceeds the overcurrent level for
the time > overcurrent suppression time, then the
evaluation board identifies the behaviour as “overcur-
rent”.
overcurrent suppression time The overcurrent suppression time is the minimum
time for which the sensor current must exceed the
overcurrent level, so that the evaluation board identi-
fies the behaviour as “overcurrent”. The sensor sys-
tem is then considered to be “faulty”.
overlap “Overlap” means that both sensor systems are
damped.
repair The maintenance carried out after fault recognition
and intended to put an item into a state in which it
can perform a required function
(IEC 60050-191-07-08).
Synonym: corrective maintenance
system output delay time The system output delay time is the time, which
passes after the digital filtering time until the switch-
ing operation at the system output, when the sensor
current falls below the trigger level.
system output extension time The system output extension time is the time, which
passes after the digital filtering time until the switch-
ing operation at the system output, when the sensor
current exceeds the tripping level. The system output
extension time is retriggerable.

trigger level If the sensor current falls below the trigger level for
the time > digital filtering time, then the sensor sys-
tem is considered to be “damped”.
tripping level If the sensor current exceeds the tripping level for the
time > digital filtering time, then the sensor system is
considered to be “not damped”.
wire break level If the sensor current falls below the wire break level
for the time > wire break suppression time, then the
evaluation board identifies the behaviour as “wire
break”.
wire break suppression time The wire break suppression time is the minimum time
for which the sensor current must fall below the wire
break level, so that the evaluation board identifies the
behaviour as “wire break”. The sensor system is then
considered to be “faulty”.
wire short-circuit level If the sensor current exceeds the wire short-circuit
level for the time > overcurrent suppression time,
then the evaluation board identifies the behaviour as
“wire short-circuit”.
1.5 Target group

2 Safety
This documentation contains important warning and safety information, which must be observed by
the user. Only by compliance with these prerequisites and safety measures, a correct operation
can be ensured.
2.1 General protective provisions
Frauscher components must be used in the original condition (= characteristics and functions as
described in the respective documentation).
Only the settings described in the respective documentation may be carried out. Apart from that,
arbitrary changes of the components are not permitted.
However, if changes of a component should be required, then Frauscher must be consulted in any
case and in advance.
The component described in this documentation must only be used for non-safety-
relevant applications.
All operational protective provisions of the rail operator must be observed.
The railway operator must ensure that only authorised personnel or people in the com-
pany of authorised personnel have access to Frauscher components.
Prior to and during works on the track, safety measures must be carried out according
to the applicable railway regulations.
2.2 Qualified personnel
Working on Frauscher components (configuration, installation, commissioning and
maintenance) must only be carried out by trained and skilled personnel.
2.3 Safety-conscious working
•The railway operator is responsible for occupational safety.
•Frauscher components may only be operated in proper condition.
•All actions carried out on Frauscher components must not impair the safety of people or the
function of the system.
•Unauthorized alterations and modifications must not be carried out on Frauscher components.

3 Structure and function
The WSC in combination with the wheel sensor RSR110 provides outputs that are triggered by a
passing wheel of a rail vehicle.
Examples of possible applications:
•trigger for AEI card reader
•trigger for lubrication system
•trigger for hot box detection system
•trigger for vision monitoring system
•trigger for warning system
•trigger for flat wheel detection system

The WSC complies with the requirements of SIL 0 according to EN 50128.
The WSC processes the wheel sensor information of the wheel sensors RSR110-001 and
RSR110-002.
The wheel sensor RSR110-001 is equipped with 2 sensor systems and can output the status of
the sensor systems (damped, not damped or faulty) and the travel direction.
The wheel sensor RSR110-002 is equipped with 1 sensor system and can output the status of the
sensor system (damped, not damped or faulty).
The WSC can be combined with:
•1 wheel sensor RSR110-001
•1 wheel sensor RSR110-002
•2 wheel sensors RSR110-002

2 RSR110-002
Figure 3.2: Block diagrams with possible combinations of the WSC with RSR110-001 or RSR110-002
In order to limit the interference voltage, the distance between 2 wheel sensors RSR110-002 that
are connected to the same WSC must not exceed 50 m and the distance between the WSC and
the higher-ranking system must not exceed 30 m.
The WSC supplies the wheel sensors with voltage and converts the analogue signals of the wheel
sensors into digital signals. The digital signals are transmitted as digital switching signals to a
higher-ranking system via optocoupler outputs.

The sensor current is evaluated level-related (normal operating sensor current level is 100 %) by
the WSC depending on the occupancy of the wheel sensor. Based on the normal operating sensor
current of the sensor system, the WSC detects a current change downwards or upwards that
results in a respective switching operation at the interfaces “optocoupler output 1 and 2” and “opto-
coupler output 3 and 4”.
Errors are indicated via the LEDs “Sys1” and/or “Sys2” on the front panel of the WSC.
Information regarding the behaviour of the LEDs can be found in chapter “LED indications on the
WSC”.
The required information and prerequisites for the application of the wheel sensor RSR110 can be
found in the documentation D4232 “Application guide wheel sensor RSR110”.
