MODEL E-1DBSL
4.3.4.2 Check relay K11 coil for an open condition. Normal resistance
should be around 2K ohm. If coil is open, replace K7.
4.3.4.3 The time delay between an actual failure and the point where the
relay trips is pre-set at the factory at about eight (8) seconds. This
delay period can be tested by throwing "on" switch S1 (on the
PCB #1). When this switch is in the alarm test mode, the flash
verified indicator (LED#1) will not be illuminated.
In case a failure occurs in the red beacon portion, either the
STLDBEACON2A or flasher failed. The system will operate in the failsafe
mode, and have beacon fail alarm at the P12 plug. Pin #8 is common, P#7 is
closed, and P#9 is open.
To troubleshoot the red beacon portion:
1) turn power off at circuit breaker to reset the light system,
2) pull Relay K8 out of socket, and set SW3 to nightmode (upward
position),
3) then turn power on at circuit breaker.
STLDBEACON2A.
IF: Beacon steady burns, replace M3 (Flasher)
IF: No light – check F5 fuse. If F5 fuse is good, replace the red LED
Beacon.
