N O T I C E
Indicates a situation which, if not avoided, may cause damage to the instrument. Information that requires special
emphasis.
Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or damage to the instrument
could occur if not observed. A symbol on the instrument is referenced in the manual with a
precautionary statement.
This is the safety alert symbol. Obey all safety messages that follow this symbol to avoid potential
injury. If on the instrument, refer to the instruction manual for operation or safety information.
This symbol indicates that a risk of electrical shock and/or electrocution exists.

disposal systems. Return old or end-of-life equipment to the manufacturer for disposal at no charge to
the user.
Certification
Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A:
Supporting test records reside with the manufacturer.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne
sur les équipements provoquant des interférences.
FCC Part 15, Class "A" Limits
Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC
Rules. Operation is subject to the following conditions:
1. The equipment may not cause harmful interference.
2. The equipment must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
4 English

residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.
Product overview
The pressurized sampling relay module has a high-voltage relay for automatic sample collection from
a pressurized sample line. The module also has low-voltage connections for optional flow pacing and
sampler program control (Figure 1). The module can be used with a portable, refrigerated or an All-
Weather Refrigerated Sampler (AWRS) that has the AS950 controller. The user must decrease the
sample pressure to less than 69 kPa (10 psi) and supply power to the relay. Refer to Figure 2 and
User-supplied equipment on page 7.

User-supplied equipment
Refer to Figure 2 on page 6 for an overview of the plumbing, mechanical and electrical parts that
must be supplied by the user. Make sure that the equipment agrees with local, regional and national
requirements.
• Junction box and cables—Connects to mains power, the ball valve and the relay module.
•Pressure reducer/regulator—Decreases the sample line pressure to less than 69 kPa (10 psi). Use
a pressure regulator that has the applicable requirements for the size of the input sample line, the
input pressure and the sample type. The manufacturer recommends Watts Series SS-263AP M1,
21 to 345 kPa (3 to 50 psi).
• Pressure relief valve—Makes sure that the pressure in the sample line is not too high. Use a tool-
adjustable pressure relief valve with sufficient discharge capacity so that the sample pressure
cannot be more than 103 kPA (15 psi).
• Motorized three-way ball valve—Connects the flow from the pressurized sample line to the
sampler inlet and then to the drain for automated sample collection. Refer to Table 1 for the ball
valve requirements.

Installation
This instrument is rated for an altitude of 2000 m (6562 ft) maximum. Although the use of this
equipment above the 2000 m altitude does not show any substantial safety concern, the
manufacturer recommends that users with concerns contact technical support.

Remove the cover
Remove the cover as shown in the illustrated steps that follow.
Mounting
Attach the module to a flat surface. The mounting surface must hold a minimum of 4 times the weight
of the equipment. Make sure that the module is sufficiently near the sampler to easily connect or
disconnect the cable to the sampler. Do not install the module in direct sunlight. Refer to the
Specifications on page 3 and to the mounting dimensions in Figure 1 on page 5. Refer to Figure 4 to
attach the module to the sampler.

Electrical installation
D A N G E R
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
D A N G E R
Electrocution hazard. Always remove power to the instrument before making electrical connections.
WARNING
Electrical shock hazard. Externally connected equipment must have an applicable country safety
standard assessment.
CAUTION
Fire hazard. Always limit current to the relays with an external fuse or breaker. Obey the relay ratings in
the Specifications section.
N O T I C E
Make sure that the equipment is connected to the module in accordance with local, regional and national
requirements.
Wiring for pressurized sampling
The high-voltage relay connects to the user-supplied equipment for pressurized sampling as shown
in Figure 2 on page 6.
Wiring requirements:
•Only use 4.3 to 11.4 mm (0.17 to 0.45 inch) diameter cable.
• Use cable with a minimum insulation rating of 300 VAC and a minimum wire size of 0.823 mm2
(18 AWG).
• Make sure that the cable jacket is correct for wet outdoor locations.
• Do not install the wiring in conduit.
• Review the relay specifications in Specifications on page 3.
1. Prepare the wires as shown in Figure 5.
2. Install the wires to the TB2 block as shown in Figure 5 and Table 2. Tighten to 0.40 Nm (3.5 inch-
pound).
3. If more than 25.4 mm (1 inch) of the cable jacket is removed, install a plastic wire tie around the
wires. Install the wire tie at a maximum distance of 19 mm (0.75 inch) from the terminal. Refer to
Figure 5.
4. Tighten the cable strain relief sufficiently to keep the environmental rating of the enclosure.
5. Install the cover. Make sure that the screws are tight to keep the environmental rating of the
enclosure.
