The EW-Y and EHE are the only control modules that accept analog signals. Neither of these pump models has the power output to supply the power for a 4-20mA transmitter. If power is required, an external power supply (12VDC preferred, but not to exceed 24VDC) is required to be installed in series.
For the EW-Y pumps, a 5-pin circular connector is required (E90495, supplied with the EW-Y module). The Analog signal is connected with the negative side (usually black) wired to the center pin (PIN 5) and the positive signal (usually red) has to be wired to the Analog Input pin (PIN 1). NOTE: Orientation of the connector should always be lined up to connect with pump - check numbers molded into back of connector or PIN numbers to be sure.
For the EHE pumps, the Analog signal is connected with the negative side (usually black) wired to the common terminal (position 8) and the positive signal (usually red) has to be wired to the Analog Input terminal (position 5).
