Connecting the Output Signals
The 4–20 mA current loop and serial output(s) are supplied from the mating
terminal block (TB2) located inside the analyzer electronics enclosure as shown
in Figure 1–6 or Figure 1–7. By default, the 4–20 mA current loop output is
factory set to source current.
Connections can be made with customer-supplied cables for the current loop(s)
and for the serial connection(s). Consult the wiring diagrams in Appendix A.
To connect the output signals
1. Disconnect power to the analyzer and open the electronics enclosure
cover. Take care not to disturb the electrical assembly inside.
2. Run conduit from the signal/alarm receiving station to the conduit
hub on the electronics enclosure labeled for signal connections.
3. Pull the customer-supplied cable(s) for the current loop(s), digital
output relays, and the external serial cable(s) through the conduit
into the electronics enclosure.
4. Strip back the jacket and insulation of the current loop, digital output
relays and serial cables just enough to connect to the mating
terminal block (TB2), shown in Figure 3–2. The mating terminal
block can be pulled up and removed from its base to make the cable
connection process easier.
5. Connect the 4–20 mA current loop signal wires to the appropriate
terminals, as indicated in Table 3–1.
The 4–20 mA current loop output is factory set to source current.
To change the 4–20 mA current loop output from source to sink,
see “To change the 4–20 mA board from source to sink” on
page 3 - 8.
Hazardous voltage and risk of electric shock . Turn off and
lock out system power before opening the electronics enclosure
and making any connections.
Conduit seals should be used where appropriate in compliance
with local regulations.
The external serial cable included in the shipping container is
provided for troubleshooting purposes and may not be the correct
length for permanent installation.
