Always-on circuit guide

This circuit will check a device - in this example a Wall Light - and restart it, if it will shut down / deactivate for a reason.

Trivia

• This little thing was invented by user "Simoyd" in discord-chat "logic-ciruit-discussion" and needed and created by user "Raumfahrtdoc"
• This is super useful to restart the Kit (Gas Generator) / Gas Generator

Improved version

thumb

Using the new Min/Max Unit as an OR gate and Compare unit as a (controlled) NOT gate, a much cheaper version is possible. Basically, it is a controlled clock that only runs when the device is off and otherwise stays at 1. The circuit can also be modified easily to make an always-off circuit (e.g. to auto-close doors), see table below.

Circuit setup

Unit name	Unit type	Connector / Setting	Source / Value
reader	Logic Reader Unit	IN	device (whatever you want to control)
		VAR	On (Open for a door or switch)
max	Min/Max Unit	OPR	Greater (Less for an always-off-circuit)
		1 (input 1)	reader
		2 (input 2)	compare
compare	Compare Unit	OUT	Equals (NotEquals for an always-off-circuit)
		1 (input 1)	reader
		2 (input 2)	max
writer	Logic Writer	IN	max (compare will also do)
		OUT	device (whatever you want to control)
		OUT VAR	On (Open for a door or switch)
