Page 18: Motherboard
Motherboard 2.2.1 Description of the Motherboard The motherboard is housed in an enclosure and consists of a large main board which houses the system memory, system’s clock battery, the AC and DC power supplies, 6 isolated analog outputs, 6 relays, 8 solenoids, 4 (Wet contact) discrete inputs and 4 (Dry contact) discrete inputs.
Page 19: Intrinsically Safe Barrier Board (Peripheral Interface)
Intrinsically Safe Barrier Board (Peripheral Interface) For Class 1, Division 1 systems, all electrical connections between the electronics enclosure and the chassis must pass through an intrinsically safe barrier. The intrinsically safe barrier connections are shown in Figure 2-2. Class 1, Division 2 analyzers do not employ an intrinsically safe barrier.
Page 20: Display Board Communication Ports
2.4.2 Display Board Communication Ports The system has two distinct communications ports housed on the display board. A USB/RS- 232 port is located on the right side of the display board. A pair of switches that can be set for USB or RS232 communications is located on the reverse side of this board on the bottom left hand corner.
Page 21: Tape Transport System
Tape Transport System The tape transport system is responsible for advancing the tape and ensuring that the system has a fresh section of white tape available at the commencement of every analysis cycle. The tape transport system is shown in Figure 2-4. Figure 2-4: Tape Transport System The tape transport system consists of the supply and take-up reels, the drive motor, the compression head, the Optical Encoder, and the optional low-tape sensor.
Page 22: Optical Encoder
2.6.2 Optical Encoder The Optical Encoder is used to ensure even spacing of stains on the lead acetate tape. The Optical Encoder is shown in Figure 2-5. Figure 2-5: Optical Encoder The left and centre pictures show the Optical Encoder as it appears when not installed in the chassis and the right picture shows how the Optical Encoder appears in the tape transport system.
Page 23: Sample Chamber Assembly
Sample Chamber Assembly The sample chamber assembly is the key component in the measurement of the H concentration in the gas. The sample chamber assembly allows the sample gas to pass onto the lead acetate tape, and also contains the detector assembly, (sensor block). An exploded view of the sample chamber assembly is shown in Figure 2-6.
Page 24: Read/Rate Aperture Strip
Certain ranges do not even require an aperture strip. Galvanic Applied Sciences provides a broad range of read/rate aperture strip sizes. The most common aperture strip sizes are listed in Table 2-1 along with the maximum ranges they are capable of measuring and their correct part numbers.
Page 25: Sensor Block
In addition, the system is capable of measuring ranges outside those listed in this table – please contact Galvanic Applied Sciences for more details. 2.7.3...
Page 26: Compression Head
reason, a Sensor Communication Alarm will be triggered and the analyzer is considered to be in a Fail State. The sensor block contains a temperature sensor that measures the ambient temperature near the sensor block. This temperature sensor can be used to trigger alarms should the ambient temperature rise above or drop below set amounts, values that can be set in the GUI.
Page 27: Sample Flow Related Components
Sample Flow Related Components The system contains a number of components that control the flow of the sample and condition it. The sample flows though the humidifier and rotameter and finally out of the analyzer through the eductor. 2.8.1 Sample Humidifier The reaction between lead acetate and hydrogen sulfide is improved if the hydrogen sulfide- containing sample gas is humidified prior to coming into contact with the lead acetate.
Page 28: Rotameter
2.0. In ProTech903 units that have the total sulfur option, the flow is controlled by rotameters for the hydrogen gas and sample gas in the sample conditioning system, and so the chassis rotameter does not have a flow control knob –...
Page 29: Eductor
2.8.4 Eductor The eductor produces a positive pressure at the exhaust while allowing the analyzer vent to remain at ambient pressure. An eductor is shown in Figure 2-13. Figure 2-13: Eductor The eductor has two purposes: • Changes in ambient pressure can affect the results produced by the system. If the system is inside a building where there is a fluctuating static pressure in comparison to the outside ambient pressure, the eductor will eliminate any influence on the tape staining.
Page 30: Total Sulfur Option
Total Sulfur Option The system is available with an oven that converts sulfur compounds to H S, so that the total sulfur content of a sample gas stream can be determined. With a dual stream setup, it is possible to measure both the H S and the total sulfur content of the same stream on the same system.
Page 31: Figure 2-14: Total Sulfurf
Figure 2-14: Total Sulfur Furnace The total sulfur furnace operates on AC voltage only, so total sulfur analyzers cannot be powered by 24VDC power supplies. The temperature is controlled by modulating the power output to the furnace from the I/O board in the electronics enclosure. This modulation is set up in the application program (Section 5.9.
Page 32: 2.10 Sample Conditioning System
A typical sample conditioning system for an H S-only ProTech903 analyzer is seen in Figure 2-15. Figure 2-15: Typical Sample Conditioning System The sample conditioning system generally consists of a Coalescing filter, a pressure regulator to regulate the sample down to 15 psig, and a valve to switch between calibration and sample gas to allow the system to be calibrated.

furnace, which is housed in a smaller aluminium enclosure (7). The sample lines are attached to the quartz tube by means of ultra-torr elbows (9) that have finger-tightened nuts to create an adequate seal. The reactions that decompose sulfur compounds take place inside a quartz reaction tube inside the total sulfur enclosure.
Page 50: Connecting Gas To Analyzer
e) Repeat steps c and d for the other end of the tube. Replace the end caps on the furnace enclosure. Be sure to align the threads correctly. The end-caps will screw on very easily if the threads are aligned correctly. DO NOT FORCE! Cross threading will seriously impair the explosion proof nature of the enclosure.
Page 51: Leak Testing The Total Sulfur Accessory
Figure 3-22: Minihelic Indicating a Good Seal (L); Connected to Vent Elbow (R) d) Check the pressure indicated on the gauge. If the pressure reads 4 or above, as shown in Figure 3-22, the tape is well sealed against the sample chamber by the compression head.
Page 52: Connecting The Eductor
Figure 3-23: Location of Cap for Furnace Leak Check c) Monitor the flow on the hydrogen and sample rotameters on the sample conditioning system. If there is a good seal in the furnace, the flow on both rotameters should drop to zero within 1 minute.
Page 53: Testing The Analyzer
Testing the Analyzer Allow the analyzer to run on sample gas for approximately 1 hour. After 1 hour, inspect the stains on the tape and compare them to those in Figure 3-25. If the stains are crisp and well spaced, the compression head is sealing the tape well against the sample chamber. If the stains have fuzzy edges, check the seal again.

Page 98: General
5.9.1 General The General box contains fields that affect the overall configuration of the analyzer. • Live PPM Enable - If a checkmark is placed in this box, the analyzer’s LCD screen will update the gas concentration as it is calculated within the analyzer on a live basis. When this checkbox is left un-checked, the screen will only update with a new concentration value when an analysis cycle has completed.
Page 99: Tape Box
This value is set at the factory and should not be changed unless instructed by Galvanic Applied Sciences personnel. After a new value is entered in this box, the Accept button must be pressed to re-calculate the value in the Stain Width box.
Page 100: Global Alarms
It is ESSENTIAL that tape length is updated via the keypad (GEN sub-menu of CNFG menu, see section 4.8.1) every time one is replaced. For example, if the user is using a 330 foot (100 meter) lead acetate tape, it is essential that he or she update the tape remaining length to a value of 330 (100) every time a new tape is installed.
Page 101: Streams Tab
5.10 Streams Tab 5.10.1 Overview The Streams tab (Figure 5-19) is used to configure the analyzer to perform the desired analyses. The format of this tab will depend on the number of streams that are present in the system and the configuration shown in Figure 5-19 corresponds to a system with 4 streams that is capable of measuring H S and total sulfur and presents the tab to edit parameters related to the H...
Page 102 Figure 5-20 corresponds to a system with 4 streams that is capable of measuring H S and total sulfur and presents the tab to edit parameters related to the zero gas (the tabs for the calibration gas and the reference gases are identical to the zero gas tab shown in the figure). Figure 5-22: Stream Tab - Zero Tab A Stream number tab and a Gas run type tab are highlighted to identify the stream/gas run type for which parameters are being edited (e.g.
Page 103: 5.10.2 Universal Gas Run Commands

Page 105: 5.10.3.2 Switching
• Consecutive Runs - indicates how many times the Gas run should be performed before switching to the next run in the run queue. If no other run is enabled and it is set up in the Automatic Sequence under the sequence tab, the analyzer will simply continue running until another run is triggered either conditionally or scheduled.
Page 106: 5.10.3.5 Stream Calibration Used
Figure 5-26: Analog Output Field 5.10.3.5 Stream Calibration Used There can only be one gain calculation per stream. If the analyzer is a one stream H S and total sulfur unit, and it has the H2 cut off option (uses hydrogen only during the total sulfur analysis), only the H2S or the Total Sulfur gas run can be used to calculate the stream gain.
