The following schematic diagram shows the Morgan Pneumatic Chemical Injector Pump Electronic Control Module (ECM) typical flow chart.

Pneumatic Chemical Injector Pump Electronic Control Module Schematic Diagram 

The Electronic Control Module (ECM) converts a 4-20mA or 1-5 VDC, to a pulsed pneumatic signal. The pneumatic signal varies from 0 – 50 pulses per minute or strokes per minute (SPM). The operating range of 0 – 50 SPM can be set to obtain a minimum of 0 – 10 (zero) and a maximum of 30 – 50 (span).
