Wi-Fi Digital Clock/Elapsed Time Indicator
with Code Blue Installation Manual
Important Considerations
The ATSTCS must be in the RUN mode for Code Blue to override.
The 12vac/vdc to 30vac/vdc signal that starts the Code Blue timer originates from equipment external to the Digital
Clock/Timer. The external equipment usually employs a switch device (i.e., a relay contact) to apply this signal. That
switching device is often referred to as the Code Blue contact.
The Code Blue contact does not have to open before resetting the Digital Clock/Timer back to normal operation, but
must be opened before another Code Blue can occur. The transition from no voltage to applied voltage (across the
K2+ and K2- terminals) initiates a Code Blue.
If the Code Blue contact opens and closes again before the Digital Clock/Timer is reset back to normal operation, the
Code Blue timer will start over from
00:00:00
.
If a power failure occurs during any Code Blue event, the Code Blue timer will start over from
00:00:00
.
