3.6 Electrical Connection
1. Remove positioner cover.
2. Locate terminal strip and carefully disconnect
(slide off).
3. Connect the 4 to 20 mA loop signal to termi-
nal points marked (+) and (-). See figure 3-10
for a wiring schematic.
4. If the positioner was ordered with an analog
output, connect output wiring to terminal
points 5 & 6, (Polarities Shown Below). The
4 to 20mA analog output requires an external
24 volt DC power supply.
5. If the positioner was ordered with switches,
connect to the switches at terminal points 1
thru 4, as shown in Figure 3-10.
6. After all connections have been made recon-
nect the terminal strip and replace positioner
cover.
