Optional Code Blue Function
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 pinout 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 network 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.
