Examine the circuit shown below and answer the following questions: 1. How is the cylinder 3A (towards the right) fundamentally different than cylinders 1A and 2A? 2. Describe 5 key features (ways, actuator, etc.) of the directional control valve 1V1. 3. Describe 5 key features of directional control valve 3V. 4. What type of device is 1V2? 5. Here's a close up of 1V2. Is it metering-in or metering-out? How do you know? 6. Empty triangle shapes appear in many places in this schematic. What do they represent? 1A 181 182 2A 282 3A 281 381 WWE 1V2 1V3 2V2 2V3 1V1 2V1 2Y1H svos H2Y2 3Y1 V 1V3 OV] OY1 211AM OZ

The process element is also called as final control element. Select one: True O False

control system answer step by step

In relation to the circuit presented below, mark the alternative(s) that you consider correct. 1 To enable actuator A2 to advance, it is necessary to switch valve V2 to the leftmost position and ensure that valve V1 is in its initial (intermediate) position. 2 Switching valve V2 to the leftmost position allows actuator A2 to advance, but for this to happen, valve V1 must also be switched to the leftmost position. 3 When activating valve V1, using the locking lever installed on the left side of it, the two actuators (A1 and A2) are allowed to advance. 4 Hydraulic pump B1 is a simple variable displacement type. 5 Valves V1 and V2 have a TANDEM center.

13) Write a program to implement the process illustrated in the figure below. The sequence of operation is to be as follows: • Normally open start and normally closed stop pushbuttons are used to start and stop the process. • When the start button is pressed, solenoid A energizes to start filling the tank. • As the tank fills, the empty level sensor switch closes. • When the tank is full, the full level sensor switch closes. • Solenoid A is de-energized. • The agitate motor starts automatically and runs for 3 min to mix the liquid. 15 • When the agitate motor stops, solenoid B is energized to empty the tank. • When the tank is completely empty, the empty sensor switch opens to de-energize solenoid B • The start button is pressed to repeat the sequence.
