An Auxiliary Crossing Driver module (AXD) provides the HXP-3
with three additional independent constant warning outputs
which may be used for:
Remote start operation.
Traffic signal preemption.
MD relay drive function when two relay drives are required
at a double track crossing.
A single AXD relay drive output to control both tracks at a
double track crossing.
The HXP-3 offers two multi-functional recorder options to
enhance record keeping, improve maintenance, and reduce
installation time. The first option is the HXP-3’s original RMM,
providing the following records for all HXP-3 configurations:
Train record log – reports all HXP-3 inputs and outputs
System event log – an accurate time-stamped sequential
log of all HXP-3 input and output status changes
Train data log – a time-stamped data log containing RX and
phase changes related to individual train moves
External event log – event logging for up to 14 optically
isolated digital inputs and 4 analog outputs (requires use
of a recorder interface module)
Onboard storage of local parameters transfers setup
information between normal and standby systems to reduce
installation time.
The second recorder option is the HCA-3 module. It provides
the following standard recorder logs (train record, system
event, train data, and onboard storage of local parameters)
as described above. The HCA-3 module also provides these
enhanced recorder features:
HCA data log – event logging for up to 14 optically isolated
digital inputs and 4 analog outputs in a GDA compatible
format (requires use of a recorder interface module)
Can be programmed with existing HCA-1 ALP executable files
Allows data retrieval either by a modem/serial port interface
or through the HXP-3’s CPU module
Offers compatibility with all HCA-1 software utility programs
