Setting the Input and Output Jumpers

Binary Output Source Power Selection Jumpers
CAUTION: Risk of Electric Shock.
Disconnect supply power to the FEC16

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 Binary Output (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 FEC) to the output load (INT position) or requires
an external power source (EXT position) for the output
load. Figure 12 shows an example of an FEC16
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 housing cover near
the UI terminals (Figure 10). 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 (default) Disabled
position (Figure 13), the 4-20 mA current loop circuit
opens whenever power to the FEC is interrupted or off.
Setting the current loop jumper to the Enabled position
(Figure 13) connects an internal 100 ohm resistor
across the UI terminals, which maintains the 4-20 mA
current loop circuit even when power to the FEC is
interrupted or off.
IMPORTANT: Current Loop jumpers must be in the
(default) Disabled position for all UIs that are not set
up to operate as 4-20 mA analog inputs.
Figure 13: Current Loop Jumper Positions
Table 5 identifies the current loop jumpers associated
with each UI on the FEC16 controller.

Commissioning
Commission the FEC with the Metasys Controller Tool
(software), either via the Bluetooth® Wireless
Commissioning Converter, ZigBee® wireless dongle,
or in passthrough mode when connected to an NAE or
NCE. Refer to Controller Tool Help (LIT-12011147).
Refer to the DIS1710 Local Controller Display
Technical Bulletin (LIT-12011270) for information on
connecting a DIS1710 display.
