FIELD WIRING
4.1 GENERAL
This section illustrates and describes the field wiring terminals and various wiring
configurations that apply to Analog, Raise/Lower, and Guard inputs, as well as the 4-20 mA
current output and the dc power source. The wiring arrangements described herein are
general and are not intended to cover every application.
4.2 TERMINAL BLOCK IDENTIFICATION
The Termination Board contains the field wiring terminals. Access to this board is obtained
by removing the cover as described in Section 2 - Installation.
Two terminal blocks (TB1 & TB2) are located on the termination Board as shown in Figure
4-1. Each of these blocks contain six (6) terminal screws for field wiring connections. TB1
contains terminals TB1-1 through TB1-6, while TB2 contains TB2-1 through TB2-6.
The function of each terminal depends on whether the Regulator is an Analog or
Raise/Lower model. The terminal designations for the Analog type are given in Table 4-1,
while designations for the R/L types are given in Table 4-2.
