6.
Press the white inspection button (one quick press) to activate the photodiode alarm. If the photodiode
alarm configuration switch (PD AL) is set to OFF, this test is skipped.
Note:
This test does not check the
photodiode itself or connections; it only turns asserts the photodiode alarm so that the alarm relay
connections can be tested.
a.
The technician should verify that the photodiode alarm relay indicates an alarm (J5
PHOTODIODE ALARM NC to COM is open).
b.
To restore (clear) the photodiode alarm, quickly press the inspection button one time. The
technician should verify that the photodiode alarm relay indicates no alarm (J5 PHOTODIODE
ALARM NC to COM is connected).
7.
Press the white inspection button (one quick press) once more to finish the automated portion of the LI.
The ‘Test in Process” LED should go OFF.
8.
Manual Photodiode Test
a.
Set the MODE switch to AUTO. This ensures that the system is now under photodiode
control.
b.
Cover the photodiode to block it from all light and wait up to 60 seconds.
c.
Verify that the “STATUS” LEDs show that the system is now in NIGHT mode.
d.
Verify that the beacon and/or marker(s) connected to the controller are on and operating as
programmed.
i.
Uncover the photodiode to allow light to strike it, or shine a light on it. With no
alarms or errors, verify that after a delay,
1.
The “STATUS” LEDs show the system is now in DAY mode
2.
The beacon(s)/marker(s) connected to the controller are off.
Important!
The Lighting Inspection is PASSED only if all of the following occur:
The BEACON alarm LED comes ON and goes OFF as described (step 2-3).
The MARKER alarm LED comes ON and goes OFF as described (step 4-5)
The photodiode alarm relay changes states to indicate an alarm as described (step 6).
The system changes modes properly as described in manual photodiode test (step 8).
If any part of the lighting inspection fails, see
Section 4 - Operating Instructions
configuration switches for the beacon and marker match the number of connected beacons and markers. If this is
correct, troubleshoot the system using procedures provided in section 4.
