The Pump Control Module (PD) is a Modbus RTU
node in the station. Each Pump Control Module is
wired using a pair of fiber optic cables to a fiber optic
converter installed inside a Supervisor Box (A).
All communications between components on the
non-hazardous location and the hazardous location
sides pass to or from the Pump Control Module along
the fiber optic connection.
The Pump Control Module serves as the connection
point and power source for other paint kitchen
components, including the Radar Level Sensor
(M, T), Fill Pump Transfer Solenoid (P), and Back
Pressure Regulator Controller (F).
Power to the Pump Control Module is supplied by
the E-Flo DC pump (C). Each Pump Control Module
has its own software installed to send instructions
from the Intelligent Paint Kitchen software to the
connected components, and to send signals from
those components back to the Intelligent Paint
Kitchen software.
