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.

Sample System Options
Back Pressure Regulator
The 3050-OLV can operate with an exhaust pressure from 0 to 15 psig, and the sensor measure-
ments (i.e. - the moisture readings) are automatically compensated for the measured pressure.
However, for proper operation of the analyzer, the exhaust pressure that the analyzer sees must
remain stable. If the 3050-OLV is to be vented to an exhaust line with varying pressure, AM-
ETEK recommends the use of a back pressure regulator (part number 305426901S) to stabilize
the outlet pressure of the analyzer.
Contaminant Trap
When using the 3050 OLV on sample streams that are likely to contain small amounts of heavy
hydrocarbons, glycols, compressor oils, or other agents that could potentially foul the QCM
sensor, AMETEK recommends the use of a contaminant trap (part number 305007901) in series
with the system dryer (see Figure 1). The contaminant trap removes thesepotential fouling
agents from the reference-gas stream, and thereby reduces the amount of these materials that
the QCM sensor is exposed to. AMETEK also recommends that the Contaminant Trap Cartridges
(part number 305527901S) are changed at regular intervals (monthly), as part of the analyzer’s
normal maintenance cycle. By proper use of the contaminant trap, and configuring the analyzer
for the sensor savor mode, the life time of the QCM sensor can be extended.
Liquid Separator
When using the 3050 OLV on sample streams that are likely to contain entrained liquids, AM-
ETEK recommends the use of a liquid separator/trap (part number 305008901S). The liquid
separator is a membrane filter system, designed to remove any entrained liquids from the
sample-gas stream. This device is required to prevent any liquid phase material from entering
the analyzer, and causing permanent damage to the QCM sensor. AMETEK also recommends
that the membrane filters (part number 305529901S) are changed at regular intervals (every 3
months), as part of the analyzer’s normal maintenance cycle.
Flame Arrestor
The use of an in-line flame arrestor is required for bringing the sample gas into, or out of, the
explosion proof casting in a Div 1 (or Zone 1) area. These devices must not be removed from
the sample system.

153050-OLV Division 2 Sample System
Isolation Valve
The isolation valve provides barrier (i.e. - a means of turning off the flow of sample gas),
upstream of the analyzer, so that the analyzer can be worked on (normal maintenance,
etc.). AMETEK recommends that an isolation valve is installed upstream of the analyzer,
and preferably at the sample tap. Because AMETEK recommends that this valve is installed
at the sample tap, we have not included it as part of the sample system package. It is the
customer’s responsibility to install a process isolation valve, prior to the installation of the
analyzer.
Power Terminal Junction Box
For convenience in installation and maintenance, the 3050 OLV sample systems are pro-
vided with a junction box (optional) for wiring the power, and signal, connections. The
wiring of the terminal strips in the junction boxes is consistent across all of the 3050 sample
systems (see Figure 2), but the box construction varies with the specific hazardous area
requirements.
Vortec Cooler
The vortec cooler uses filtered compressed air to cool industrial control cabinets without
the use of refrigerants. Hot air in the cabinet is vented to the surroundings through a
built in relief valve in the cooler. The mechnical thermostat is set to maintain the internal
cabinet temperature between 90 and 110°F.
