Operation
Checking the ERTune™ Menu Bar for Warnings
The Menu Bar of ERTune™ program displays two
warnings: No Feedback and Simulation.
The No Feedback warning indicates that the program is
communicating with the controller, but is not receiving a
feedback signal.
This warning generally indicates a wiring problem. Refer
to the Getting Started or the Installation Variations
section to nd the correct wiring for your application and
verify that your wiring has been installed correctly.
• A common error is not connecting the yellow wire
(pin 4) and the tan wire (pin 12) when using a
4–20 mA feedback transducer.
• Also check to make sure the voltage/current
select jumpers are in the proper position for your
application. Refer to Checking the Conguration of
the Jumpers earlier in this section.
The Simulation warning indicates that the ERTune™
program has been opened in Simulation Mode.
In Simulation Mode, the program responds
normally to controls. However, it does not actively
communicate with a controller, even if the controller
is powered up and properly connected.
Simulation Mode is useful for training purposes, but
should be closed when you wish to communicate
with the ER5000.
