Triplex System Example
A customer who currently runs a duplex system would like to retrofit an existing triplex system with the following requirements:
• Three similarly sized pumps would run the system.
• A maximum of two drives should be running at any point; the third drive is a backup.
• Alternation should only happen when pumps are not running (sleeping).
• If one of the analog pressure feedback transducers should fail, read from a working one and notify the customer of the failure
by the alarm display.
• Setpoint is 90 PSI, feedback scale is 145 PSI, start level is 75 PSI.
