SACA 101 Study Guide Exam with Questions and Answers – 100% Solved
Besides alarm screens and error messages, do you know what else an HMI is used for? - ✔✔✔-
An operator can troubleshoot many problems directly from the HMI panel.
can you calculate the power in a simple circuit? - ✔✔✔-Power(W) = Current(A) * voltage(V)
can you define continuity and state its importance? - ✔✔✔-Electrical continuity means there's a
complete path for current to flow in a circuit.
Sometimes, a lack of continuity is desired, such as when a light switch is set to off. However, if a
wire or a component doesn't have continuity when it should, it prevents current flow and circuit
operation.
Can you describe how a CNC machine works? - ✔✔✔-A CNC (Computer numerical control)
machine is a type of motion controller that can coordinate the speed and positioning of multiple
axes at the same time to cut complex features into the metal part.
Can you describe the 8 deadly wastes? - ✔✔✔-1. excess inventory
2. overproduction (more product than the next process or customer needs)
3. excess motion (movement by a team member that doesn't add value)
4. over processing (putting extra effort into a process that doesn't add value to the customer)
5. transportation (any movement of the product within the facility)
6. waiting
7. underutilized people
8. nonconforming product (any product that doesn't meet design specifications)
Can you differentiate value added and non value added activities? - ✔✔✔-Value-added
activities transform or shape material and information that meets customer requirements.
example: cutting metal to make a part shape, or adding paint to a product's surface.

Non-value-added activities take time resources or space, but do not add to the value of the
product or service. example: product inspection, or rework.
Can you explain line balancing? - ✔✔✔-Line balancing spreads the workload across
workstations based on the speed of processing to avoid bottlenecks and excess capacity. Line
balancing allows the company to identify under-used and overworked staff.
can you explain the operation of a 5-port, 3-position directional control valve? - ✔✔✔-When
the spool is in the middle position, air flow is blocked between all ports, this causes the cylinder
to hold its position.
Pushing the operator handle causes the spool to shift, which makes the cylinder extend.
Pulling the lever in the opposite direction causes the spool to shift to the third position and
reverse the port connections, which makes the cylinder retract.
can you explain the operation of a double-acting pneumatic cylinder? - ✔✔✔-when pressurized
air enters the port on the cap end of the cylinder, it causes the piston and rod assembly to
extend. air on the other side of the piston is pushed out through the rod end port to
atmosphere.
pressurized air entering the port on the rod end causes the piston and rod assembly to retract.
air on the other side of the piston is pushed out through the cap end port to atmosphere.
can you explain the operation of MEMORY logic? - ✔✔✔-Memory logic is used to keep an
output energized after the input signal that turned it on has been removed.
Can you explain the operation of two types of transistors used in electronic sensors? - ✔✔✔-1.
The PNP transistor provides a high signal at it's output when the sensor is energized, or has
detected the presence of an object.

2. the NPN transistor operates the opposite of the PNP transistor.
when the sensor is off, the voltage at the sensor's output terminal is high, the sensor's output
terminal is zero volts when the sensor is energized.
Can you give three examples of advanced manufacturing tools and techniques? - ✔✔✔-
Industrial Robotics
Modeling and Simulation
Advanced Manufacturing
Can you identify 5 types of servo robots? - ✔✔✔-1. articulated
2. cartesian
3. gantry
4. SCARA
5. delta
Can you identify 11 types of hazards in the workplace? - ✔✔✔-1. Impact
2. Penetration
3. Compression
4. Chemical
5. Temperature
6. Harmful dust
7. Radiation
8. Light
9. Biological
10. Electrical
11. Mechanical
