5 Pump Control
5.1 Wire Connectors / Wire Leads
The PPMC300 has Turck EuroFast male receptacle coming out of the front of the device. This connector both
powers the on board controls and provides external I/O for the device. A mating cable is available and wire colors
shown in the diagram relate to the optional cable.

5.2 Pump Operation
There are several modes which the pump can operate.
•
Plug-n-Play
– This is a constant run mode, meaning that when the pump is powered on it will operate
without any additional signals. This option can be ordered in one of two ways:
o
User Configurable
– This means that the internal potentiometer will be preset to the specified
cycle rate so that the pump will run when powered on in the initial set up of the pump by the
customer. However, the user has the ability to tweak the cycle rate by adjusting the internal
potentiometer.
o
Hard Coded
– This means that the processor will be preprogrammed at the factory to operate at
the specified cycle rate only and is not adjustable by the end user.
•
External Control
– This is an idle operation and does not start-up when powered on. When the pump is
powered on then it watches for external control signals to define its operation. The external controls can
be given in the following ways:
o
Analog Input
– This external control uses a 0-5 VDC analog signal to define the cycle rate. The
analog signal can change the operation signal from 10 to 400 CPM.
o
Digital inputs
– This external control allows an external PLC to directly control the timing of the
pump’s air valves, thus controlling the pump’s cycle rate.
o
Free Flow
– In some cases it is advantageous to know that when the pump is idle, that there is
still a forward path that is free to flow. This can help in pump priming, and in decontamination. A
positively pressured supply line will open the checks and allow fluid to flow though the pump.
The following sections will go into more detail about how each of these control modes work.
5.2.1 Plug-n-Play
Working with Plug-n-Play is very easy, power the pump when you want it to pump, and remove power from the
pump when you don’t want the pump to operate. The cycle rate is based off of either the factory programmed
