Question 5 please

additional for the question 5: Note in this problem that the STOP and PULL-ROPE inputs are failsafe; that is, they are N/C switches (not N/O) connected to IN2 and IN3. This means that when STOP button is pressed or the rope is pulled, IN2 or IN3 turns OFF, which should stop the conveyor. It is recommend (but not required) that you begin with the attached program. It will initialize the inputs STOP and PULL-ROPE to be ON. Your program MUST have three (and only three) inputs: START, STOP, and PULLROPE. It MUST also have two (and only two) outputs: MOTOR and HORN. If you assign any additional inputs or outputs you will be penalized. You may use as many other internal programming components as you wish (relays, timers, counters, etc.).

An electrical equipment enclosure is to be mounted on an above-ground swimming STOP pushbutton connected to IN2, and a N/C PULL ROPE switch connected to IN3. OUTI will operate the conveyor MOTOR, and OUT2 will operate a warning HORN. Wher START is pressed, the HORN will sound for 10 seconds. After 10 seconds, the HORN will stop sounding, and the MOTOR will switch ON. Once started the MOTOR can be stopped by pressing the STOP pushbutton or pulling on the pull rope. The STOP and PULL ROPE must be overriding inputs. pool pump. It will be exposed to outdoor weather and an occasional splash o lorinated (corrosive) pool water Obviously, we would need to keep fingers and tools from fitting through an openings in the box. (a) What is the optimum NEMA number for this application? (b) What is the optimum IEC IP number for this application? 2. Select the best IEC IP number for an electrical box used in a textile mill. It must be dust tight and be able to withstand an occasional water hosedown by the cleaning crew. 6. A light curtain is connected to a PLC such that when the light curtain is interrupted IN1 of the PLC is turned OFE OUT1 of the PLC is connected to a horn such that when OUT1 is ON, the horn sounds. Draw the ladder rung of Figure 12-4, and then add additional code so that if RUN is ON and the light curtain is interrupted RUN will switch OFF, and the horn will pulse repeatedly ON for 0.5 second and OFF for 0.5 second. The horn will continue to sound, and RUN cannot be reactivated until the system is reset pressing the STOP switch. 3. Convert the IEC rating IP64 to the nearest equivalent NEMA rating. 4. Redraw the ladder diagram of Figure 12-4 to allow for the addition of a N/C pull rope switch that will disable the RUN output when it is pulled 5. Devise a ladder diagram to control a production line conveyor. There will be a momentary N/O START pushbutton connected to IN1, a momentary N/C
