Question 25 Suppose we have an Allen-Bradley MicroLogix 1000 controller connected to a pair of momentary-contact pushbutton switches and contactor controlling power to an electric motor as shown in this illustration: "Start" switch "Stop" switch OL contact * + 24V DC 1/0 L COM DC OUT 85-264 VAC L1 1 L2/N 1/1 1/2 1/3 DC 1/4 1/5 COM Power Run Fault Force | VAC VDC VAC VAC 0/0 0/1 VDC VDC + a VAC 012 VDC 0/3 E "Start" switch "Stop" switch OL contact COM 1/4 1/5 + 24V - DC 1/0 1/1 1/2 1/3 DC L COM - DC OUT 85-264 VAC 1 L1 L2/N + Power Run Fault Force VAC VDC Contactor coil VAC VAC 0/1 VDC 012 VDC Log -51 VAC Leg 0/0 VDC 0/3 This motor control system has a problem, though: the motor refuses to start when the "Start pushbutton is pressed. Examine the "live" display of the ladder logic program inside this Allen-Bradley PLC to determine what the problem is, assuming an operator is continuously pressing the Start pushbutton as you examine the program: I: 0/3 I: 0/2 I: 0/0 0:0/2 0:0/2 Identify at least two causes that could account for all you see here.
