When PumpSmart is powering a 2-wire process transmitter, the current loop must be
completed with a jumper from the PS220 analog input negative terminal to XD24-5. In
cases where multiple transmitters are powered you may jumper between each analog
Example: Pressure Control
Application w/ Vibration Tx
Example-2-wire process transmitter and remote 4-20 mA reference
(setpoint) signal from PLC or DCS.
Example: Pressure Control
Application
Example-non 2-wire (4-wire) process or reference signal
connections. These are signals where the 24Vdc for the loop is
powered by the remote device. Examples include PLC, DCS, flow
meter, etc.

All instrumentation shielding must
be terminated at grounding lugs
provided by the PS220. Do not
terminate Shielding at sensor end.
Expose the shield of the control wire cable

The DII L is a drive permissive and must be
closed (24Vdc) for the drive to operate. If
your application does not require a Drive
Permissive, DIIL may be bypassed by
jumping DIIL to XD24 connections #2 or #4
