NOTE: When not using 4-20 mA outputs, use the supplied resistors to
connect CH-1 and CH-2 to GND. If these resistors are not connected and the
4-20 mA outputs are not used, a “P” will appear on the display, indicating an
open loop condition.
Sensor Wiring (J3)
Connect the sensor wires (for on-board, remote or stand-alone) to
the appropriate wiring terminals as follows.
24 V: Red wire from sensor head
485A: Yellow wire from sensor head
485B: Black wire from sensor head
GND: Green wire from sensor head
NOTE: Shielding from either the controller or remote sensors should be
bonded to the enclosure screw located inside the .
NOTE: The 24 V terminal supplies 24 VDC to the sensor for power. This
terminal should not be connected to the output of a 24 VDC power supply.

NOTE: For dual-sensor configurations, place both of the same colored wires
in the appropriate terminal block and firmly tighten.
