1.4 PLC CONTROL SCHEMATIC
Shown below is an example of the fiber optic end of stroke detection for a Maxim
Pump. The Programmable Logic Controller (PLC) control schematic shown will
allow the Maxim to be controlled by a PLC. Some of the features that can be
programmed are:

Start and stop pump

Monitoring approximate flow rate

Leak sensing

High and low flow rate detection

Preventative maintenance counter

Cycle counting

Oscillator control override
NOTE: See examples of ladder logic programs in Section 4.10.
