Something has to set and unset B3/14 for your program to work. It could be somewhere else, such as in an operator or machine control panel program, or in another PLC that is communicating with this one. B3/14 (B3:0/14) could also be controlled as part of a range, maybe including all the bits in Word B3:0; bits B3:0/0 up to B3:0/15. You could search for all occurances of B3:0. It appears that some Word B3:0 bits are used mostly by a "MMI" (Man-Machine Interface).
Either that, or you have accidently caused some bad errors in the program!
All I personally can determine:
B3:0/0 Undefined Always-On bit in Lad 2 Rung 000
B3:0/1 = CLAMP CLOSE BIT
B3:0/2 = CLAMP OPEN BIT
B3:0/3 = TRANSFER ADVANCE BIT
B3:0/4 = TRANSFER RETRACT BIT
B3:0/5 = CYCLE INTERLOCK
B3:0/6 = CURE TIMER DONE
B3:0/7 = AUTO CYCLE ONLY
B3:0/8 = ADVANCE TRANSFER DURING AUTO CYCLE
B3:0/9 = MMI MAX PROFILE DONE <-------Indicates B3:0 bits 9,10,11,& 14 may be coming from a MMI panel
B3:0/10 = PASSWORD OK
B3:0/11 = CLAMP SET ZERO
B3:0/12 = OSR #1- One Shot Rising in Lad 2 Rung 1
B3:0/13 = HIGH PRESSURE ENABLE
B3:0/14 = TRANSFER SET ZERO <--------This is the one to find!
B3:0/15 = OSR #2 in Lad 2 Rung 9.
