1.3 PROBE ASSEMBLY INSTALLATION (E MODEL ONLY)
Optic Cable: 1mm core; 1/4” PFA protective tubing.
 Install seal into head.
 Install probe assembly into head.
 Thread probe cap into head hand tight only, no tool needed.
 Connect fiber optic cable to sensor. NOTE: Minimize bends in fiber optic

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.
