Introduction
Wi-Fi Digital Clock/Elapsed Time Indicator
with Code Blue Installation Manual
Code Blue
Description
The Code Blue feature provides an override which forces the clock into a special count up elapsed time mode.
No matter which of the three normal functions is being displayed, Code Blue input will cause the unit to begin
counting elapsed time from
00:00:00
. All other functions of the unit continue to operate in the background during
a Code Blue.
Operation
A Code Blue is initiated by applying a signal ranging from 12vac/vdc to 30vac/vdc to the K2+ and K2- terminals.
See the sample wiring diagram below for more detail.
The Code Blue timer is the highest priority function of the clock/timer while in the run mode. No matter which of
the 3 normal functions is being displayed, the Code Blue input will cause the clock to begin counting up elapsed
time from
00:00:00
.
The Code Blue timer can be stopped and the time held for viewing by pressing the
START/STOP
button on the
ATSTCS switch panel. The Code Blue timer cannot be restarted from the switch panel.
To reset the clock back to normal operation, the
RUN/SET
switch must be set to the
SET
position momentarily
and then returned to the RUN position.
All other functions of the clock continue to operate in the background during a Code Blue. Time of day and time
corrections from the Wi-Fi receiver will not be affected. The standard count up timer and the count down timer
will continue as well. However, if one of these timers is switched on for display when a Code Blue occurs, that
particular timer will be reset when the clock is reset back to normal operation.
