Troubleshooting Controllers - Johnson Controls MS-FEC1611-1U Installation Instructions Manual

Setting the current loop jumper to the Enabled position
the UI terminals, which maintains the 4–20 mA current loop circuit even when power to the controller is interrupted
or off.
Important: Current Loop jumpers must be in the Disabled (default) position for all UIs that are not set up to operate
as 4–20 mA analog inputs.
Table 7 identifies the current loop jumpers associated with each UI on the FEC16 controller.

Setting Up an Integral Local Display
FEC1621 models have an integral LCD and push-button user interface that allows you to set up and monitor the
FEC, the FEC I/O points, and the modules and I/O points connected on the SA bus. FEC1611 models do not have
an integral display. For detailed information on setting up and operating the user interface of the DIS1710, refer to
the DIS1710 Local Controller Display Technical Bulletin (LIT-12011270).
Commissioning Controllers
You commission field controllers with the Controller Configuration Tool (CCT) software. Refer to the Controller Tool
Help (LIT-12011147) for detailed information on commissioning controllers.

Troubleshooting Controllers

Observe the Status LEDs on the front of the controller and see
an integral local display, refer to the DIS1710 Local Controller Display Technical Bulletin (LIT-12011270).
