MAGNUM 620E PUMP OPERATION / MAINTENANCE MANUAL PAGE 9
2.4 PLC CONTROL SCHEMATIC
Shown below is an example of a Programmable Logic Controller (PLC) control
schematic shown will allow the Magnum to be controlled by a PLC for the
Magnum pump. Some of the features that can be programmed are:

Start and stop pump

Monitoring approximate flow rate (contact factory for displacement factors)

Leak sensing (section 2.5)

Preventative maintenance counter

Cycle counting or End-of-Stroke detection

Oscillator control override
Figure 2-5
Note : The use of ONE EOS probe is applicable for cycle counting to monitor pump
operation and monitor cycles for maintenance intervals. To control pump cycling
requires 2 EOS probes and amplifiers.
