Setting the Input Jumpers
CAUTION
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.
CAUTION
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.
UI current loop jumpers
The UI current loop fail-safe jumper pins are located on the circuit board under the controller cover
near the UI terminals (Figure 10).
Note:
Current Loop Jumpers
are not included
with the PCA3613-0.
Figure 12: Current loop jumper positions
Set the current loop jumper to the Enabled position (Figure 12) to connect an internal 100 ohms
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.
