Issued August 2012 UNCONTROLLED WHEN PRINTED Version 2.1

5.3 Hardware Configuration

Refer to the level crossing monitor block diagram in Appendix C and drawing X14 - X26 &

X49, X50 of the Standard Circuits or the particular circuits for the level crossing.

The hardware comes preconfigured in regard to links. These may be checked by referring

to the relevant parts of Section 3.

The generic data must be customised for the particular Level Crossing. The configuration

data must be uploaded to the monitor. This process is detailed in Section 7.

5.4 Commissioning Procedure

This section describes the commissioning procedure. Details of the commissioning

activities are recorded on a copy of the Level Crossing Monitor - Test and Commissioning

form. This form is provided in Appendix B and is to be followed in order while

commissioning the level crossing monitor.

Before turning on power on to the Level Crossing Monitor the links must be set as per

section 3.2.2.3. The test form identifies links that may not have been set correctly. These

must be checked and set correctly especially Link 12-13 which is positioned near the

front of the I/O board near the push button reset switch.

Check wiring, connectors and that the correct version EPROM is fitted for the level

crossing. It is important to check the correct polarity of the power.

Turn power on and check that the LEDs on the monitor behave as described in section

3.1. It does take 2 seconds or 3 seconds before LED 4 starts flashing. This is due to the

time taken to perform self tests. At start up a System Fault will be indicated since there is

no Configuration Data in the memory of the level crossing monitor.

Connect a PC running one of the level crossing programs (LX_MAINT or Cerberus) to

serial channel B. The serial cable plug into COM2: on the PC and Channel B on the

monitor.

Start the PC program and use the menus to Establish communications with the monitor.

It is possible for a new monitor at startup to be in a state where it is continuously trying to

report changes of state. This is indicated by LED 3 on the I/O card being lit. This reporting

of changes of state must be disabled before others commands will be accepted.

Set the Pin numbers. To do this you need to know the Master pin number. The operations

pin number required, and the maintenance pin number required. These may be obtained

from Signal Engineering or the District Signal Engineer.

After the pin numbers are set it is time to send the expression data (configuration data).

See sections 7.2 & 7.3 for details on how to prepare this data to create the binary (.bin)

file.

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.
