The 6V AC voltage is commutated by VD8-VD11.It is filtered by C5.It provides +6V working voltage for triggering the control circuit and protecting the circuit.It is reduced by R9,and it will go to VL3.Then it lights VL3.The 1500V AC voltage goes to the aerial bare metal line of electric fence by control turns L1 and L2.If the aerial bare metal line is not touched by any animals and there is no current in the control turns L1 and L2 ,control contacts of reed switches SA1 and SA2 are off state.V1-V4 stop.K1 and K2 are at release position.The alarm circuit is not working.VL1 and VL2 are not be lighted.BL don't give a sound.
