Setting the Input and Output
Jumpers
Binary Output (BO) Source Power
Selection Jumpers
Risk of Electric Shock:
Disconnect supply power to
the controller before attempting to adjust the Binary
Output Source Power Selection Jumpers. Failure to
disconnect the supply power may result in electric shock.
Mise En Garde: Risque de décharge électrique:
Débrancher l'alimentation de l'controller avant tout
réglage du Binary Output Source Power Selection
Jumpers. Le non-respect de cette précaution risque de
provoquer une décharge électrique.
Important:
Do
not
connect an external power source
to a BO when the BO power source jumper
is in the internal power (INT) position.
Connecting external power to a BO that
sources internal power can damage the
controller and void any warranties.
The BO source power selection jumpers determine
whether a BO provides internal power (sourced from the
controller) to the output load (INT position) or requires
an external power source (EXT position) for the output
load.
shows an example of a controller BOs
and the associated power selection jumpers to the right
of the BOs terminal block.

Universal Input Current Loop Jumpers
The Universal Input (UI) current loop fail-safe jumpers
are on the circuit board under the controller cover near
the UI terminals (
). When a UI is defined (in the
system software) as a 4-20 mA Analog Input and the UI’s
current loop jumper is in the Disabled (default) position
(
), the 4-20 mA current loop circuit opens
whenever power to the controller is interrupted or off.
Figure 13: Current Loop Jumper Positions
Setting the current loop jumper to the Enabled position
(
) connects an internal 100 ohm resistor across
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.

Setting Up an Integral or Local
Display
FX-PCG1621 models have an integral LCD and push
button user interface that allows you to set up and monitor
the FX-PCG, the FX-PCG I/O points, and the modules
and I/O points connected on the SA bus. FX-PCG1611
models do not have an integral display, but can be
connected to an FX-DIS1710 Local Controller Display.
For detailed information on setting up and operating either
an integral user interface or a remotely connected
FX-DIS1710 display, refer to the
FX-DIS1710 Local
Controller Display Technical Bulletin (LIT-12011666)
