1. Verify POWER SWITCH is turned OFF.
2. Verify LOCAL / REMOTE switch is set to LOCAL.
3. Verify MODE switch is set to DAY.
4. Turn on circuit breaker to apply power to Master Controller.
5. Turn on circuit breaker to apply power to Flash-heads.
6. Turn POWER SWITCH to ON.
7. Verify that the Master Controller LED test sequence has started (See
EPM-00001152 - Installation and Operating Guide for High Intensity
Obstruction lighting). The test sequence will exercise every LED and relay
(e.g. it will quickly sweep through the Flash-head Status LEDs in red and
green mode).
After the test sequence completes, the Flash-head status LEDs for the
selected number of Flash-heads shall be lit red then change to green as
the Flash-heads report (DS1 - DS24, Figure 3.6-1 Item 4).
8. After 1 minute, verify the number of Flash-head status LEDs (DS1 - DS24,
Figure 3.6-1 Item 4) that are lit green matches the total number of white
Flash-head lights (including AOL) on the tower (if there are n Flash-heads
on the tower, Flash-head status LEDs DS1 - DSn shall be lit green). Verify
that the remaining unused Flash-head status LEDs (DSn+1 - DS24) are
turned off.
9. After all the flash-heads report good (green), check the Master Control
board’s relay monitoring LEDs which should display following:
i. DS29-DS32 GREEN,
ii. DS33 OFF (DS29 - DS33, Figure 3.6-1 Item 5.) Verify Photocell
status LED DS28 (Figure 3.6-1, Item 3) is lit green.
iii. Verify Day Mode LED DS25 (Figure 3.6-1, Item 3) is lit red, and
the Twilight and Night LEDs (DS26 and DS27 respectively Figure
3.6-1, Item 3) are not lit.
iv. Hold down the RESET switch for approximately 1 second and
verify the LED test sequence has restarted.
