Select the option Send Config data. This option is selected to upload the
previously compiled expression data. The compiling of this expression
data is described in another section of this manual. After entering the pin
number you then must enter the file name of the expression data. This
file has a .bin extension and would normally be in the same directory as
the LX_Maint program or Cerberus program. After the upload is complete
the level crossing monitor is ready to be commissioned and tested.
Get the monitors ID and Status. Using this information record the Data
details, Code version, and Crossing number.
Set the name using the menus.
Set the date and time using the menus and the operations pin number..
You must always set the date and time even if it is correct as their may
be some change in the way in which the clock is dealt with between
software versions.
Clear the log using the menus and the maintenance pin number. The
System Fault should clear.
Using the menus request a System test.
Reset the monitor to ensure the oldest event in the log has the correct
date and time.
Display the Input information. Check that the names for each used input
bit correspond with the circuit book. Check that the input states are as
expected.
Display the Output information. Check that the names for each used
output bit corresponds with the circuit book and the ".io" configuration
data file. Check that the output states are as expected.
Display the Intermediate terms information. Check that the names
correspond with the ".io" configuration data file. Check that the
intermediate states are as expected.
Display the Timer information. Check that the names correspond with the
".io" configuration data file. Check that the timer states and lengths are
as expected.
Display the analogue data. Check that the information corresponds to
both the ".exp" configuration data file and the circuit book. Check that the
information reflects the current expected state.
Check and adjust battery charger. A additional load of approximately
1.0A is required to power the level crossing monitor and the modem.
This additional load may result in not enough trickle charge current for the
level crossing battery. Approximately 100-300 mA of trickle charge
current is required (measured with a current gun) into a fully charged
level crossing battery. The battery charger voltage may need to be
increased.
