OPERATING TECHNIQUES 1 Flying Splice Turret Control W hen W V220 is used for control of turret sequencing the READY contact closure is normally used to activate the circuitry which rotates the turret into the Ready to splice position and accelerates the new roll to splicing speed The WEB END contact closure normally triggers the circuitry which makes the actual splice fires the cutoff knife signals the tension control system to enter its splicing mode and shifts tension control from old brake to new brake FORM NO L 20170 C 0503 10 3 WEB END switch defines the Web End point at 001 to 999 feet of remaining web length c Atthe time that the web reaches the READY trigger point whether diameter or remaining length the Ready relay contact Terminals 4 and 6 will close and the READY LED lamp will glow To prevent false triggering W V220 will not change the relay state or light the lamp until the trigger point is achieved for three consecutive rotations of the unwind roll d W ENDLED lamp glows and the W eb End elay contact Terminals 5 and 6 closes when W V220 reaches the W eb End trigger point for three consecutive rotations CORE DIA rotary switch defines the outside diameter of the roll core to WV220 Diameter is expressed as 00 1 to 99 9 inches NOTE CORE DIA must be the outside diameter of the core 4 da POWER switch applies AC powerto WV220 SHAFT 1 and SHAFT 2 LED lamps are
