The ST1210 sensors can be installed and wired directly to the UNI-TRAN Premium Plus housing and terminal board as per the wiring diagram (see Figure 10 ) or they may be remotely mounted using a sensor separation kit (JB2-3-ASSY) which is composed of a junction box and terminal strip (see Figure 11). The sensor and kit are then connected to the UNI-TRAN Premium Plus.

When sensor separation is required for units using the ST1210 Hydrogen Sulfide sensor use a minimum of 18AWG shielded copper instrument wire for separations up to 50 feet and 16AWG for separations up to 75 feet. Consult factory if greater separations are required (see Figure 11).

NOTE:

If the 4-20 mA signal is not used, connect a jumper between the 4-20 terminal and the

Common Terminal.
