This document is uncontrolled when printed.
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.
6.4 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 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 Standards & Technical Services
Engineer 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.
