Needs Maintainance Cover

The Needs Maintainance Cover is a cover added by GregTech 5 Unofficial.

Usage
Place the Needs Maintainance Cover on any Control Block of a Multiblock that needs maintainance. By clicking on the cover with a screwdriver the number of maintainance issues needed to emit a redstone signal must be changed.

Tip
Since most multiblock controllers have no free side to place redstone logic next to them, it is recommended to use a Redstone Transmitter attaced to Input/Output Hatch/Bus.
