Cerberus Level Crossing Monitor Field Equipment Manual TMG E1261

Issued August 2012 UNCONTROLLED WHEN PRINTED Version 2.1

If the Level Crossing has interlocked signals or other special conditions like an adjacent

ground frame then examine the *NOT_STOP, *NOT_START, *STICK_WARN,

*STICK_FAIL expressions must be checked and either deleted or modified.

Additional expressions may be added to check for track failures, detection failures, or

additional alarm or warning conditions. Examples of these are:

*TRACK_FAULT =T 1h 0m 0s !*TRACK_UP

*DETECT_FAULT =T 30m 0s !6NK & !6RK

If the crossing is not being remotely tested then replace the *NO_TEST expression with:

*NO_TEST =T 36h 0m 0s TEST_ZK.

Edit the new ".cfg" file for the crossing. Change the title of the file from generic.cfg to your

chosen name name.cfg. No other modifications are to be done to this file.

A number of warnings are included in the generic configuration files regarding deleting of

variable and inputs such as Special Intermediate variables. Please adhere to these

warnings.

6.3 Data Generation

To produce a binary file ready to be uploaded to a level crossing monitor use the batch

file "COMPEXP". This is used in the format "COMPEXP name".

e.g. typing in >compexp name

This will compile the 3 files (.exp, .io, .cfg) created above and compile them. If there are

any errors then you will soon know about it. If a error in the expression or i/o files is

detected then the computer will write the faults and errors to a file called name.err. By

examining this file you can debug your expression and i/o files.

Assuming all is well then the compiled files will be linked to the main code to create one

file called 'name.bin'. This file is the file that is then placed in the directory used by

LX_MAINT or ‘Cerberus’ ready for uploading into the required level crossing monitor.

Files required in the current directory or path for data generation:

compexp.bat

newexp.bat

generic.cfg, generic.io, generic.exp

ppgen.exe Version 3.4 or later.

A51.EXE, L51EXE, OHS51.EXE, FAD.EXE, FCSUM.EXE.

addr.equ

The relevant ".io", "..cfg", and ".exp" files in the same directory.

6.4 EPROM programming

Normally a programmed EPROM with R3.7 or later software will be supplied with each

level crossing monitor.
