48 Operating the Controller
Sleep Mode
Sleep mode is available on 1758-RTU controllers only. 1758-FLO controllers
do not provide Sleep mode due to requirements for periodic execution of the
AGA gas flow calculations.
DataSite controllers are capable of extremely low power operation when in
Sleep mode. In Sleep mode, the following will occur:
• All programs stop executing.
• The power supply of 3.3V for circuit is shut off.
• The real-time clock and timer continue to function.
• 12V DC power is not affected.
DataSite controllers can switch to Sleep mode under control of the application
program. If one of the following conditions occurs, the controller will be
switched out of Sleep mode to return to normal operation.
• A real-time clock alarm, as defined by an application program, is
triggered.
• A high voltage level signal is applied to the WakeUp input.
