To connect the analog outputs/analog inputs:
1. Disconnect power from the analyzer and open the electronics
enclosure cover. Take care not to disturb the electrical assembly
inside.
2. Run conduit or rated armor cable with the appropriate cable glands
from the analog outputs/inputs receiving station to the conduit hub
in the right outside corner of the electronics enclosure.
3. If using conduit, pull the customer-supplied cables for the source
outputs through the conduit into the electronics enclosure.
If using rated armor cable, wires are already provided. Skip to
step 4.
4. Strip back the jacket and insulation of the current loop output and
serial cables just enough to connect to the mating terminal block.
5. Connect the 4-20 mA current loop IOUT1/IOUT2 output wires to the
appropriate terminals, as indicated in Table 2–2 on page 2–10.
6. Connect the serial cable wires to the appropriate terminals according
to Table 2–1 (TB1).
7. To complete the connection, connect the other end of the current
loop wires to a current loop receiver and the external serial cable to
a serial port on your computer.
Hazardous voltage and risk of electric shock . The analog
outputs are not protected against any input voltage. Any voltage
applied to the analog outputs can cause irreversible damage to
the circuit.
Hazardous voltage and risk of electric shock . Turn off and
lock out system power before opening the electronics enclosure
and making any connections.
The 4-20 mA outputs are configured as sourcing to provide power
to the loop. If a PLC/HMI is used to provide power to the loop, an
isolator will be required.
