4 Answer the questions in sequence for Figure 932 Assume all
4. Answer the questions, in sequence, for Figure 9-32. Assume all switches are turned off after each operation. a. Switches S2, S12, and S5 are turned on in order Will output PL5 e energize Why? b. All switches except S7 are turned off. Will RTO start timing? Why? c. Switches S3 and S8 are turned on in order. Will pilot light PL2 come on? Why? d. When will timer TON function? e. Assume all switches are turned on. In what order will the rungs be scanned? f. Assume all switches are turned off. In what order will the rungs be scanned
Solution
a)here first the switch S2 is closed it will go to subroutine if S13 is PL3 will be energized.
Then S12 is ON,t hen it will jump to LBL.
Then S5 is closed it will energize PL5.because for energizing PL5, S5 is enough.
b)RTO will start timing because for its function S3 or S9 or S10 should be on.
c)PL2 will turn on. When switch S3 is closed, it jumps to LBL 20 after that for RTO, S7 should On.
When S8 is on it will directly turn on PL2.
d)with the switches S12 and S6 are closed, timer TON functions.
