4. Select the Type of module via the drop down, then select
Install.
5. The WebUI will indicate
Waiting for service msg…
when the message appears, the
user needs to press the Echelon
®
Service button on the iLOD, and the Web UI will
indicate when the process is successful.
4.12.4 Lamp Calibration of iLOD
The lamp calibration process for an iLOD sets the internal threshold levels used by the iLOD
software to detect flashing lamp current. These levels are site-specific. It also is used by the
application program to determine the number of lamps and the current draw that is present for a
properly operating crossing. This process is not the same as factory calibration. Factory
calibration is performed on the iLOD units before shipment.
NOTE
All key presses in the following procedure are done from the front panel
keypad on the GCP5000 Display module
.
1. To access Lamp Calibration, select:
Program View > 3) SEAR Programming > 9)
SEAR Setup 2) Lamp Calibration
on the Display module, OR access the WebUI (see
preceding iLOD installation procedure) and select
System View > SEAR > Lamp
Calibration
.
2. If there is an application program loaded into the SEAR, enter the number of flashing
lamps for each iLOD sensor when requested.
NOTE
If the site has Gate Tip Sensors installed, when asked to flash the lamps,
make sure the gates are level before pressing
Enter
. The current reading
is allowed to “settle” for 15 seconds
.
3. Depending on the configuration of the crossing, it may be necessary to repeat this
process with AC power to the crossing turned off. At some installations, the process may
be repeated more times depending on configuration (split tracks, etc.).
NOTE
A pair of flashing lamps count as one lamp and each tip light counts as
one flashing lamp. Count only the lamps that go through that sensor. The
lamp count may be on the site plans
.
4. When the process is complete, the Display module will return to the SEAR Program
Menu.
