APPLICATION

PIRVOLLT is a point-type infrared hydrocarbon gas process monitor. It provides a continuous 4-20 milliampere (mA) output signal that is proportional to methane vapor concentrations from 0 to 100% by volume.

PIRVOLLT is designed for use in extractive vapor sampling systems where the vapor concentration is likely to be above the lower ﬂammability limit (LFL). Typical applications for the PIRVOLLT include hydrocarbon well logging and petroleum exploration where a volumetric measurement of the target gas is required.

Appendix A - CSA Appendix B - ATEX/CE Appendix C - IECEx

OPERATING MODES

Warmup

When power is applied to the PIRVOLLT, it enters a Warmup mode (for approximately one minute) in which it performs diagnostic checks and allows the sensors to stabilize before beginning normal operation. The current output during this period is 0 mA. At the end of the warmup period with no faults present, the PIRVOLLT automatically enters the Normal operating mode. If a fault is present after the warmup, the current output will indicate a fault.

WARNING

Always ensure that the detector/termination box hazardous (classified) location ratings are applicable for the intended use.

DESCRIPTION

DETECTION METHOD

PIRVOLLT operates on the infrared absorption principle. A beam of modulated light is projected from an internal infrared source to a reﬂector, which sends it back to a pair of infrared sensors. One of the sensors is designated reference and the other active, with different optical ﬁlters in front of the two sensors to make them selective to different infrared wavelengths. The reference wavelength is unaffected by combustible gases, while the active wavelength is absorbed by combustible gases. The ratio of the active to the reference wavelength is computed within the PIRVOLLT to determine the concentration of gas present. This value is then converted into a 4 to 20 mA current output for connection to external display and control systems.

CURRENT LOOP OUTPUT

During normal operation, the PIRVOLLT has a 4 to 20 mA current output that is proportional to gas concentrations from 0 to 100% by volume methane. A current output less than 4 mA indicates a fault condition (see Table 1).

SIGNAL DISPLAY DEVICE

If a local or remote digital display for indication of detected gas concentration is required, it is recommended to utilize a scalable display device with a clearly marked unit of measurement in % by volume. Under no circumstances should a % LFL unit of measure display module be used to display the PIRVOLLT signal output.

Normal

In the normal operating mode, the 4 to 20 mA signal level corresponds to the detected gas concentration. The PIRVOLLT continuously checks for system faults or initiation of calibration, and automatically changes to the appropriate mode.

Fault

Faults detected during warmup, normal operation, or calibration are indicated by the current loop output as shown in Table 1.

Calibration

The PIRVOLLT is calibrated at the factory for detection of methane. No ﬁeld calibration is required under normal circumstances.

In the event the PIRVOLLT optics are fouled and complete optics disassembly for cleaning is required, device rezeroing may be required after re-assembly. Refer to the “Calibration” section for details.

NOTE A momentary connection of the calibration lead wire to DC negative (common) of the power supply initiates the zero and span calibration sequence. When wiring the PIRVOLLT, use care to isolate it from accidental contact with the PIRTB and/or other conductors.

3.1 95-8631

INSTALLATION

CORRECT

INCORRECT

DEVICE MOUNTING ORIENTATION

It is highly recommended that the PIRVOLLT be installed in the horizontal position. See Figure 5.

TERMINATION BOXES (PIRTB)

The PIRVOLLT is designed to be threaded into a termination box, which is then mounted to a solid, vibration-free wall or post.

The use of shielded cable in conduit or shielded armored cable is recommended for optimum RFI/EMI protection. In applications where the wiring cable is installed in conduit, the conduit must not be used for wiring to other electrical equipment. To assure proper operation, the resistance of the connecting wire must be within the speciﬁed limits. The maximum distance between the PIRVOLLT and power source is determined by the power supply capability and wire size. See Figure 2 to determine the proper wire size and maximum wiring distance allowed.

Det-Tronics offers the Model PIRTB termination box in two styles for use speciﬁcally with the PIRVOLLT:

• Tall Cover Model includes a window. See Figure 6.

• Short Cover Model uses solid cover. See Figure 7. This

model can also be used for detector separation.

The PIRTB terminals are UL/CSA rated for 14 to 22 AWG wire, and DIN/VDE rated for 2.5 mm2 wire.

GENERAL WIRING REQUIREMENTS

NOTE The wiring procedures in this manual are intended to ensure proper functioning of the device under normal conditions. However, because of the many variations in wiring codes and regulations, total compliance to these ordinances cannot be guaranteed. Be certain that all wiring complies with applicable regulations relating to the installation of electrical equipment in a hazardous area. If in doubt, consult the authority having jurisdiction before wiring the system.

It is important that moisture not be allowed to come in contact with the electrical connections of the system.

The use of proper piping techniques, breathers, glands, and seals are required to prevent water ingress and/or maintain the explosion-proof rating.

WIRING PROCEDURE

IMPORTA N T

Do not apply power until the wiring procedure is complete and has been veried.

1. Locate the sensor where it will be accessible for maintenance. Excessive heat or vibration can result in premature failure of any electronic device and should be avoided if possible.

2. The PIRTB should be electrically connected to earth ground.

3. Figure 8 shows typical wiring for stand alone operation. Figure 9 shows typical wiring for PIRVOLLT with Det-Tronics’ PIRTB. Figure 10 shows the wiring terminals located inside the PIRTB. The PIRVOLLT wiring color code is:

Red lead = +24 volts dc Black lead = – (common) White lead = 4 to 20 mA signal output Yellow lead* = Calibration input Green lead = Chassis ground

* If the calibration wire (yellow lead) is not being

used, do not connect this wire to ground. Trim excess length and insulate wire so no shorting can occur.

DETECTOR SEPARATION (OPTIONAL)

In applications where the PIRVOLLT must be installed in a different location from a control device (such as a transmitter), a PIRTB termination box must be installed at the PIRVOLLT location to make the electrical connection. Refer to Figure 11 for a typical separation diagram.

Wiring Requirements for Detector Separation

Shielded four wire cable is recommended for connecting the PIRTB to the transmitter. Cable with a foil shield is recommended. The shield of the cable should be open at the PIRTB and connected to earth ground at the transmitter termination box. Ensure that the shield wire is clipped short and insulated with electrical tape to prevent accidental grounding at the open end.

The maximum distance between the PIRTB and the transmitter is limited by the resistance of the connecting wiring, which is a function of the gauge of the wire being used.

Mounting and Connecting Procedure for Detector Separation

The PIRTB should be mounted to a solid, vibration-free wall or post. The termination box should be electrically connected to earth ground.

1. Lubricate the sensor threads with low vapor pressure silicone grease, then install the sensor in the conduit entry of the PIRTB. It should be tight to ensure an explosion-proof installation, however, do not overtighten.

2. Connect the PIRVOLLT wires to the terminal strip in the PIRTB.

3. Connect the leadwires from the transmitter to the appropriate terminals inside the PIRTB. Do not ground the shield at the PIRTB. Ground the shield at the transmitter end only.

4. Check the connections inside the PIRTB and place the cover on the termination box.

5. Mount and wire the transmitter as described in the instruction manual provided by the manufacturer.

NOTE It is important to maintain a minimum of +18 volts dc (including ripple) at the PIRVOLLT. When determining the appropriate wire size for the installation, refer to Figure 2. Be sure to take into account the distance from the power supply to the PIRVOLLT or to the transmitter and then to the PIRVOLLT to ensure that the power requirements are met.

3.1 95-8631

STARTUP PROCEDURE

TROUBLESHOOTING

NOTE Caution should be exercised when applying this and any electronic device to explosive vapor extraction and measurement applications. Typical hazards in these applications include small tting vapor leaks, resulting in dangerous gas concentrations near or within the system enclosure. Any spark or arc may result in a re or explosion in these conditions. Always inspect all ttings for leakage before commissioning, and always remove power from all electronic devices before performing maintenance on the vapor extraction system tubing, ttings, and hardware.

1. Inhibit the output loads that are actuated by the system to prevent activation of these devices.

2. Check that the PIRVOLLT has been wired properly.

3. Apply power to the system and allow the PIRVOLLT to operate for a minimum of 2 hours, then check zero and verify gas response.

4. Place the system in normal operation by reactivating the output loads.

Refer to Table 2 to isolate and correct malfunctions with the PIRVOLLT.

MAINTENANCE

It is recommended to have spare IR Modules on hand (see “Spare Parts” section). Use Table 2 to isolate and correct malfunctions.

IMPORTANT MAINTENANCE NOTES

• Hydrocarbon-based grease emits hydrocarbon

vapors, which will be measured by PIRVOLLT, resulting in elevated gas concentration readings. Use only silicone-based grease (not

hydrocarbon-based grease) when lubricating threads on the PIRVOLLT and associated termination box. A suitable grease is listed under

“Spare Parts” in the Ordering Information section of this manual.

• It is recommended to keep spare IR modules

(See “Spare Parts” section) for eld replacement in the event of a malfunction.

Table 2—Troubleshooting Table

0.0 mA CPU system fault, warmup Ensure that power is applied and that the warmup period is complete (1 minute). If fault does not clear, replace the unit.

3.1 95-8631

DISASSEMBLY AND CLEANING PROCEDURE

The PIRVOLLT should be inspected periodically to ensure that its performance is not impaired by fouled optics or by clogging of the sample draw cup or hydrophobic ﬁlter. Inspection and/or periodic maintenance involves three different areas.

IMPORTANT

Remove power before disconnecting and removing the PIRVOLLT for maintenance.

Sample Draw Cup. Perform a visual inspection of the sample draw cup and associated plumbing, and clean as required. External ﬁltration of sample stream is recommended.

Hydrophobic Filter. The ﬂow of gas through the ﬁlter can be inhibited by an accumulation of mud or other contaminants. To inspect the hydrophobic ﬁlter, disassemble the PIRVOLLT as described below. If the ﬁlter appears to be fouled, replace it.

Optics. Cleaning of the optical surfaces is required only if an optical fault is indicated (1.0 mA current output signal from the PIRVOLLT). This procedure is most easily accomplished on a bench.

Required materials: Clean, ﬂat work surface, foam tipped swabs (no cotton), isopropyl alcohol, screwdriver.

CAUTION

The PIRVOLLT contains semiconductor devices that are susceptible to damage by electrostatic discharge. An electrostatic charge can build up on the skin and discharge when an object is touched. Therefore, use caution when handling the device, taking care not to touch electronic components or terminals. If the electronics assembly is removed, it should be placed in an

anti-static bag or box while stored or transported.

A static safeguarded work area is highly recommended (if available) for disassembly and cleaning of the PIRVOLLT.

1. Remove the sample draw cup from the front of the PIRVOLLT by pulling it straight off the electronics assembly (no tools needed). See Figure 12.

2. Perform a visual inspection of the sample draw cup and associated plumbing, and clean as required. Also inspect the two O-rings inside the sample draw cup and clean, lubricate or replace as required.

3. Loosen the two captive screws on top of the mirror assembly (Figure 12) and remove the mirror assembly and hydrophobic filter from the electronics assembly.

4. Thoroughly douse the interior of the mirror assembly as well as the foam tipped swab with isopropyl alcohol. Use the swab to gently cleanse the surfaces of the reflecting mirrors inside the mirror assembly. After cleaning with the swab, flush out the mirror assembly using a liberal amount of isopropyl alcohol. Tip the mirror assembly with mirror openings downward to remove accumulated isopropyl alcohol and particle contaminants. Repeat the alcohol flush to remove any remaining contaminants. Allow the mirror assembly to air dry in a dust-free location.

IMPORTA N T

Do not insert any sharp object into the mirror assembly. Scratching of the mirrors will void the PIRVOLLT warranty. Do not use cotton tipped swabs or buds as they are likely to leave fiber residue.

5. Clean the two windows on the electronics assembly using the procedure described above. When the mirror assembly and electronics assembly are thoroughly dry, proceed with re-assembly.

6. Slide a new hydrophobic filter over the end of the mirror assembly, then carefully seat the mirror assembly and hydrophobic filter against the base of the electronics assembly. Be careful not to crumple or fold the hydrophobic filter.

7. Tighten the two captive screws on the top of the mirror assembly. Tighten the screws evenly. Do not over-tighten (6 inch-pounds recommended).

8. Slide the sample draw cup back onto the PIRVO LLT.

9. Check for leaks around the PIRVOLLT sample draw cup.

CALIBRATION

In the event the PIRVOLLT optics are fouled and complete dis-assembly is required for cleaning, a zero calibration of the device may be required. This procedure ensures the signal output level is at 4 mA, and does not require application of span gas.

NOTE Zero drift will be indicated by a constant offset in one direction either above or below 4 mA. The presence of background gas would be indicated by a small but constantly changing output.

IMPORTANT CALIBRATION NOTES

Ensure that the detector has been operating for at least two hours before calibrating.

Do not open the explosion-proof enclosure

when power is applied to the system unless the appropriate permits have been procured.

Calibration Procedure

To perform a zero calibration of the PIRVOLLT, follow the sequence described in Table 3.

NOTE The calibration sequence is initiated by momentarily connecting the calibration lead to the negative lead (common) of the power supply using either the Cal Magnet or an external switch.

If the Det-Tronics PIRTB with magnetic Cal Switch

is being used, this is accomplished by holding the Cal Magnet near the side of the termination box for one second. The location of the Cal Switch is shown in Figure 10. An alternate way of accomplishing this is to install a pushbutton switch between the yellow lead and the power supply common.

Factory calibration is recommended for complete device calibration. Contact Det-Tronics for additional information.
