Program Description

RUNG001 is to operate Clipping of a bottle. When I:1/0 is detected which is an address of Bottle Enter
proximity switch, O:2/0 energizes which is connected to perform first position of the clip which holds the bottle.

RUNG002 & RUNG003 are to energize O:2/1 which operates rotating of a bottle by rotating motor in forward
direction by 1800, bottle is turned upside down after 2secs bottle is held.

RUNG004 & RUNG005 are used to energize O:2/2 which is connected to the solenoid valve coil to sprinkle
water inside from the bottom of upside down bottle. This is done when I:1/1 proximity detects the presence of
upside down bottle. Water sprinkling is done for 2secs and solenoid coil is de-energized.

RUNG006 is used to de-energize motor forward coil and energize motor reverse coil with which is
connected to O:2/3 to take bottle back to its main position. This is performed when I:1/2 detects the presence of
a bottle to leave.

RUNG007 and RUNG008, when O:2/3 is energized, after 3secs, Bottle is released by the clip. O:2/3 is the
output to activate 2nd position of the clip which is to leave a bottle.
