Figure 13 Typical Installation

NOTE: Any unused ports should be blocked with suitable ¾” male NPT plugs. Detcon

supplies one ¾” NPT male plug with each J-box enclosure. If connections are other than ¾”

NPT, use an appropriate male plug of like construction material.

2.6 Field Wiring

Detcon Model FP-100 sensor assemblies are designed to connect to a host electronic controller’s 4-20mA

input. Wiring designations are ‘PWR’, ‘GND’ and ‘MA’ (sensor signal). The maximum wire size for

termination in the Junction Box is 14 AWG.

NOTE 1: Shielded cable is required for installations where cable trays or conduit runs include

high voltage lines or other possible sources of induced interference. Separate conduit runs are

highly recommended in these cases.

NOTE 2: The supply of power should be from an isolated source with over-current protection.

Terminal Connections – with Junction Box Option

CAUTION: Do not apply System power to the sensor until all wiring is properly terminated. Refer

to Section 2.7 Initial Start Up

1. Remove the junction box cover.

2. If the sensor has the 100 Series Display option installed, unplug the display from the terminal board by

pulling the display out of the junction box. The display option plugs directly into the terminal board’s

Beau Connector.
