Installation
Unpacking and Inspection
Remove components from the packing case(s) carefully; check contents against packing list.
Inspect all components for obvious damage and broken/loose parts or fittings. Notify the car-
rier and AMETEK Service (1-800-537-6044) immediately if parts are missing or damage is found.
Sample System Space Requirements
Nema-4x enclosure - approximately 64 x 35 x 67 cm plus clearance for analyzer connections.
Refer to Figure 3.
Power Requirements
The System is shipped according to the customer order and is fused and set for the voltage of
the required mains power. The power requirements are stated near the power entry for the
analyzer and in the Specification Section of analyzer manual.
System Tubing
Recommended system tubing is 1/8 inch OD, 316 stainless steel meeting ASTM #632 specifica-
tions (AMETEK PN 571061017 or equivalent).
Dry Reference Gas
A dryer (AMETEK Dryer PN 305400901S or equivalent) is required to dry reference gas to less
than 0.025 ppmv.
Dryers must be periodically replaced. In normal use, the dryer (PN 305400901S) should dry a
50-ppm reference gas to specification for 1 year.
Sample pressure and temperature requirements
Pressure reduction is user supplied to ensure sample pressure to the analyzer remains within
the minimum and maximum range of 20 - 50 psig. The pressure reducer/regulator with gauge
should be installed near the sample tap in-between the tap and analyzer. Refer to figure 2.3 in
analyzer manual. For optimum performance, sample line should be heat traced to maintain a
constant sample temperature. Optimum sample gas input is 60°C.

Mechanical Installation
Locate the 3050-OLV system as close as possible to the sample source. The unit should be
protected from direct exposure to weather and sunlight, and located so that the ambient tem-
perature specifications will not be exceeded.
1. If not already installed, install a main process shut-off valve and pressure reducer (rec-
ommended) at the sample tap. Refer to figure 2.3 of users manual.
2. Mount system in selected location and bolt in place. Refer to figure 3.
3. Connect the exhaust and drain fittings to an appropriate ventilation system.
Insure venting does not empty into or create a hazardous atmosphere.
4. Open the main process shut-off valve and purge sample line to an appropriate area
for at least five minutes. Close the main process shut-off valve. This will help prevent
contamination from entering the cell.
5. Connect the sample line to the sample inlet 1/8-inch compression fitting.
6. Reinspect process line connections making certain that all are connected to the proper
external supply, exhaust, and drain tubing such that there shall be no release of hazard-
ous process gas to the atmosphere.
7. Open valve to dryer 1/4 to 1/2 turn prior to closing the lid.
Electrical Connections
1. Access terminal block. Refer to figure 6.
2. Connect the 4 to 20 mA analog output and alarm contacts from the terminal block to
user recording equipment as shown on wiring diagram figure 2. Refer to figure 5 for
conduit locations.
3. Connect serial communication from analyzer to the PC being used for customer param-
eter setup. Refer to figure 2 and 5.
RS-232 Out - Connect RS-232 cable to the back of the analyzer.
OR
RS-485 In - Connect RS-485 in cable to the terminal block. Refer to wiring diagram
figure 2.
RS-485 Out - Termination plug is installed at the factory. Remove the RS-485 termination
plug from the RS-485 Out connection when communicating with multiple analyzers
except for the last analyzer in a chain.

4. Connect line power to analyzer.
5. When installing external wiring to the outer protective enclosure, use appropriate
thru-wall bulkhead connections suitable for the hazardous area classification and the
environmental conditions to be encountered. As an example, for Class 1, Division 2,
Nema 4(X) outdoor applications, use only gasketed, self-sealing, UL Listed conduit hubs.

Notes
1.
Cable should be shielded with single twisted pair.
2. Cable shields should be connected to both the analyzer and the DCS. If this is not
possible, cable shields should be tied to the chassis at each 3050-OLV. If this is not
possible, tie the shield at the PC or DCS to chassis and remaining shield to the chassis
through a 0.1 mF @ 500V capacitor.

3. e 3050 signal common is connected to earth ground. If the analog output is also
grounded, the analog output will no longer be electrically isolated. Contact AMETEK if
this situation occurs.
Ω4. Analyzer power must be removed when connecting or disconnecting the 4-20 mA signal.
5. e 4-20 mA loop circuit must have a load resistance of between 100 and 500 ohms or
malfunction may occur (Max 100 ohms when local 4-20 ma display is present). If a loop check is
performed, a 100 ohm resistor must be placed in series with the ammeter.
6. In Loop Powered mode, remove factory installed 100 Ω resistor at TB3-5 to TB3-6
and jumper at TB3-3 to TB3-4.
7. In Self Powered mode when the optional local 4-20 ma display is present and no remote device is in use,
the circuit must be completed with factory installed jumper from TB3-3 to TB3-4 and an additional
100 Ω resistor from TB3-5 to TB3-6.
