4.12.9 Verify Operation of iLOD
Once good communication is verified, further checks of the iLOD can verify that it is seeing
normal amperage/flash rates.
To view these values in real-time, select
IO & Logic View > 4) SEAR
and then scroll to choose
the iLOD unit to view. It is under SEAR I/O > Digital Inputs 1..16 in that screen both sensors are
shown, the first iLOD unit will show EB1, EN1. When the lamps are flashed, both sensors
should display that the lamps are on, the amperage reading, and the flash rate in flashes per
minute.
These values are shown in real-time; they should be steady and not fluctuate. If the value
fluctuates, the lighting circuit will need to be checked for intermittent operation.
NOTE
iLODs must have been installed in the network and field-calibrated before
verifying operation
.
4.12.10 SEAR IIi Communication
Testing communications to the office can be accomplished using a menu function to generate a
test alarm and by creating events that generate alarms. Before testing the SEAR IIi by sending
alarms to the office, the unit must be configured for communications in the Site Setup. Once a
SEAR IIi is configured through Site Setup and communication is established, the location will
register itself with the WAMS office.
Test Communications with SEAR option on the Display module menu.
•
Access the WAMS Test Message via Diags & Reports > 2) SEAR > 3) WAMS Test
Message.
•
Once you select WAMS Test Message, it will automatically start the process.
•
Under
Status,
it will display the message “In Progress” until the process is complete,
either with a successful test, or when the system times out.
•
Enter the ATCS address of the other crossing.
•
To send a test packet to the WAMS office:
•
Press 5
•
Enter railroad-specific office address.
•
Refer to circuit plans for office address.
Typically, the office ATCS address is 2.RRR.00.0000, where RRR is the ATCS number
assigned to the railroad.
