ER5000 Installation Variations — Wiring Diagrams
The ER5000 has a wide range of wiring options, allowing it to be configured 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 configuration. 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
Model (ER5050) on page 110 before following the steps listed below.
Step 1: Connect the ER5000 to a
24V DC Power Supply
All wiring configurations 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.

NOTE NOTE
This section shows variations to the
typical ER5000 configuration described in the
CAUTION CAUTION
Getting Started section.
NOTE NOTE
WARNING WARNING The (+) and the (-) in the tables and
figures of this section refer to the differential

inputs. Both must be connected for the system
to work properly.
WARNING WARNING
NOTE NOTE
Setpoint is set digitally by writing to
variable #37 (ID_SETPOINT), using the ERTune

program or your own coding. Refer to the Internal
Variables and the ER5000 Software Development

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 specific wiring diagrams and descriptions in this section.
