The driller safety protection controller
The working principle of the circuit The driller safety protection controller consists of the trigger switches Sl-Sn, resistors of R1 and R2, potentiometer RP, capacitors C1-C3, LED VL1 and VL2, diodes of VD1 and VD2, time-based circuit IC and relay circuit K, see as figure 8-86. The 6.3V AC voltage from the driller lighting transformer provides with DC working power supply for the IC after it is rectified by VD1 and filtered by C3.
