Unable to set the time on an SE7000 controller

Issue

I read the documentation to set the CLOCK and is very easy to do, but if you try it doesn't work. The controller always displays the Alarm "SetClock" and the time at the default value " Monday" 12:00 AM

Product Line

Field Devices, SmartStruxure Lite

Environment

SE7000 controller with scheduling capability

Cause

The Real Time Clock in the SE7000 uses the 50/60hz AC frequency to operate, if the unit is powered from a DC power source the Real Time Clock will not function and the clock time will always display Monday 12:00.

Resolution

Power the controller from an AC power source if the RTC is required
