Active Machine Detector

The Active Machine Detector is a cover added by GregTech 4. It will emit a Redstone signal if the machine it is connected is performing a process. The strength of the Redstone signal is based on how close the process is to complete; for example, when just started (less than 6.6% complete), it will emit a strength of 1, and when it is almost complete (more than 93.3% complete), it will emit a Redstone signal of 15.

The Active Machine Detector has four modes. The modes can cycled through by right-clicking the cover with a Screwdriver. The modes are:
 * Normal.
 * Inverted, which will invert the signal emitted.
 * Ready to work, which will make the cover emit a Redstone signal of 15 when all of the machine's processes are finished.
 * Not ready to work, which will make the cover emit a Redstone signal of 15 when the machine is processing.

The Active Machine Detector can be applied to any side of a machine by right-clicking a side. It can be removed by right-clicking the cover with a Wrench.
