RUNG004, RUNG005 and RUNG006 are used to operate bit shift register BSL and Capping Machine with
address O:2/2.
Whenever proximity sensor with input I:1/2 detects bottle and O:2/1 is energized, I:1/2 sets B3:0/0 bit. This
bit is shifted when again this coil is energized.
From proximity to capping machine, distance is 7 steps. Hence bit B3:0/6 of B3:0 register is used to operate
capping machine.
Capping machine motor is connected with output O:2/2 which is energized till the process is running. Hence,
simply letting master coil run the capping machine motor.
When Accumulator value is between 2 to 18, pneumatic supply is activated and screw capping is operated
that is when cylinder motor is stopped for 2secs and timer is between 0.2-1.8secs.
