Wiring

Sample Input Tubing

Make sure power is off before you begin installation.

Rear Panel Connections:

1. Remove terminal cover to access interface board.

2. Install main process shut-off valve and pressure regulator at sample tap.

Gas Connections:

1. Remove VCR plugs and gaskets from sample inlet ﬁ tting and exhaust ﬁ tting and con-

nect sample input tube and exhaust tube. Vent exhaust to vent system.

2. Connect instrument air supply to instrument air ﬁ tting.

3. Select 120 or 240VAC on voltage selector. Mark operating voltage on rear panel.

Electrical Connections:

1. Make sure the installed power cord has an approved terminator plug per NEC and

CEC regulations.

2. Wire the analyzer per requirements for hazardous or non-hazardous location per

instructions in Chapter 3 of the manual.

Communications Connections:

1. Connect 4-to-20 mA analog output and alarm/data valid terminals on interface board

to analyzer using metallic signal conduit.

2. Connect the RS-232 or RS-485 serial communications to analyzer. RS-485 connection

shares same cable and metallic signal conduit as analog output and alarm/data valid

contacts.

3. RS-485 Communications: RS-485 terminator switch is turned to "ON," only if your

unit is a dedicated analyzer or if it is the last analyzer in a chain of multiple analyzers.

Replace all analyzer covers before continuing.

Initial Startup:

1. Open the main shutoff valve at the source.

2. Turn on the AC power at the source.

3. Once the sample ﬂ ow starts, the analyzer will be in normal operating mode. Allow

analyzer to warm up for 45 minutes.

Dry Down:

Allow 5 to 7 days for the analyzer to dry down and stabilize. At end of dry down period,

concentration value on display will be stable and recorded data will level off. Zero

alarms will still be on the display. See Chapter 3 in the manual for more details on dry

down and information on shortening the dry-down process.

Zero Cycle:

Perform a zero cycle after the dry down.

Press Zero key and then the #8 key (arrow down) until you see "Zero." Press the Enter key to select.

Zero cycle takes approximately 2 hours. When zero cycle is complete, the analyzer will adjust the zero offset and automatically return to normal sampling.

Verify Cycle:

We do not recommend performing a verify cycle during initial startup. The analyzer and its internal generator should be allowed to equilibrate for at

least 24 hours before you run a verify cycle.

Press the Zero key and the #8 key (arrow down) until you see "Verify." Press the Enter key to select. The verify cycle takes about 3 hours, and a

"zero" is automatically performed at the start of the veriﬁ cation cycle. When the verify cycle is complete, the analyzer adjusts the span and automati-

cally returns to normal sampling.
