ER5000 Installation Variations — Wiring Diagrams
The ER5000 has a wide range of wiring options, allowing it to be congured for virtually any application requirement. If your application calls for a variation on the
standard installation, use the diagrams on the following pages to build a complete conguration. Note that in your actual application, multiple wires may terminate
at the same connection: for example, the violet wire (Pin 7), which is the (+) connection to the power source, may also connect directly to the transducer or other
external devices.
If your application requires a Hazardous Location model (ER5050), read Installing a Hazardous Location
Model (ER5050) on page 110 before following the steps listed below.
Step 1: Connect the ER5000 to a
24V DC Power Supply
All wiring congurations begin by
connecting the ER5000 to a 24V DC
power supply. The external power
supply is necessary for the controller to
operate and is part of all applications.
Power Supply page82
Step 2: Connect the Setpoint and Feedback Source
Setpoint and feedback sources vary with application. Use the links below to match the setpoint and
feedback sources for your application to specic wiring diagrams and descriptions in this section.
