When locally servicing an installed and configured (commissioned) unit, use this feature before removing power.
Prerequisites: The controller has been commissioned (
Niagara 4 installed, platform configured, a station installed) and the unit is running the station. The BEAT LED is flashing at the normal 50%/50% On/Off duty cycle rate.
Perform the following steps:
- Press and hold the recessed SHUT DOWN button just until the Green SHUT DOWN LED illuminates.
- Release the SHUT DOWN button.
The station and software is put into a safe state. The shutdown process starts. During shutdown, the
SHUT DOWN LED blinks in working mode.
When shutdown is done, the SHUT DOWN LED turns off.
- You can safely remove the 24V power from the unit.
If the system cannot be put into a safe state, the SHUT DOWN LED blinks in error mode: two quick 200ms flashes On, 3 seconds off, repeating.
