The
points switch controller is used for controlling
and monitoring electrically-set points in conjunction with point zone
protection. This device combines control and safety functions
in an especially compact unit. This means that controlling can, if required, be
implemented centrally or decentrally, i.e. in the vicinity of the points (e.g. in a
control box). |
 |
Applications:
- Electrical
locally-set points (EOW)
- Classification yard automation
-
Decentralized itinerary control
- Gravity
shunting systems
- Depot
automation
- Electronic
interlocking for shunting and
freight traffic up to 50 km/h
 |
Control
Functions:
- Processing
switching commands issued by connected control elements
(e.g. button switch, an operating console, radio control,
control panel) or from the MC module data interface or from
the trailing side via the axle counter circuit's double
wheel sensor.
- Controlling
and monitoring the points mechanism (4-wire technology).
- Self-acting
reversal operation if the end position is not attained
(programmable).
- Setting a
preferred position (normal position) to which the points
automatically return (programmable) after the axle counter
circuit has been entered and left.
- Functional
dependence on other points e.g. flank protection or
double-slip points (programmable).
Safety
Functions:
-
Decentralized signaling of the points position with a point
signal
- Switching
protection due to points-clear / points-occupied
notification provided by an axle counter system that is
integrated into the control system. This means that the
points cannot be switched at the wrong time below a vehicle
whose axles have been counted within the zone that is
denoted by the double wheel sensor.
|
Advantages:
- Compact and
service-friendly setup using Euro plug-in board technology
- Increased
temperature range from -25° C to +85° C
-
Decentralized installation is possible in control boxes
which has the effect of reducing cabling costs
- Connection
to network via MC data bus interface (2-wire cable or fiber
optics)
- Event log
and diagnosis via data line
- Small
dimensions
- Remains
uninfluenced by rail currents, harmonics, radio interference
