FLOW CHART WIRING DIAGRAM
The following tables give the complete
wiring layout of the ER3000 wiring
assemblies, which are connected to
the J3 and J4 terminal blocks. Refer to
the tables to ensure proper wiring of
external devices.
Note: The (+) and the (-) refer to the
differential inputs. Both must be
connected for the system to work properly.

Step 1: Select Voltage/Current
Jumper J5 (top board – see below
right for Figure 1) – Select Jumper
position* for:
1: Analog Setpoint
2: External Feedback
3: Auxiliary input #1
4: Auxiliary input #2
For all the above jumper positions:
• Jumper not installed:
configured for 1-5V.
• Jumper installed: configured
for 4-20mA.
*Not on 0-10V models
Step 2: Plumb the external
regulator and transducer
Use safety information on pages
4-6 & 8-10 prior to pressurization
and operation of all equipment.
Step 3: Mount the ER3000
Four 8-32 UNC screw holes are
provided.
Step 4: Electrical wiring
Connect ER3000 to a power supply,
transducer, and computer (if needed),
using the tables on this page.
Note: All electrical wiring must be
in accordance with applicable local
standards (see pages 4-6 & 8-10).
Step 5: Tune program (if using
a computer)
Download the Tune program onto
your computer.
Step 6: Read and follow the
safety sections on page 4-6
& 8-10 carefully prior to
pressurization and operation
of the system.
