Question about Controls Systems
A chemical processing plant requires a simplified safety control system to monitor critical
conditions in one of its reactors. The system must evaluate three key parameters and activate two
response levels. A combinational circuit with 3 sensors and 2 alarms needs to be designed for this
purpose.
Sensors:
A: Reactor temperature (0 = normal, 1 = high)
B: Reactor pressure (0 = normal, 1 = high)
C: Mixture pH level (0 = normal, 1 = out of range)
Alarms:
X: Warning alarm
Y: Activation of the emergency shutdown system
System requirements:
1. The warning alarm (X) should activate when:
At least two parameters are out of range.
• Or when the temperature is high (A = 1) and any other parameter is out of range.
2. The emergency shutdown system (Y) must activate when:
• All parameters are out of range simultaneously (A = 1, B = 1, C=1).
•
Or when the temperature and pressure are high simultaneously (A = 1 and B = 1), regardless
of the pH level.

An industrial soft drink production plant needs to implement a quality control system for its bottling
line. The system must monitor four critical parameters and activate different alarms depending on
the conditions detected. It is required to design a digital circuit with 4 inputs and 3 outputs for this
purpose.
Inputs:
A: Carbonation level (0 = normal, 1 = high)
B: Liquid temperature (0 = normal, 1 = elevated)
C: Line pressure (0 = normal, 1 = low)
D: Filling speed (0 = normal, 1 = low)
Outputs:
X: Minor adjustment alarm (triggered when an odd number of parameters are out of range)
Y: Major revision alarm (triggered when at least three parameters are out of range)
Z: Adjacent parameters alarm (triggered when exactly two adjacent parameters are out of range
System requirements:
1. The minor adjustment alarm (X) should activate when an odd number of parameters are out of
range, indicating the need to make minor adjustments to the process.
2. The major overhaul alarm (Y) should activate…
