Users of a hard copy version can refer to the contents page to find the relevant information. Users of the soft copy version can use the hyperlinks from the contents page as well as the hyperlinks between sections. Please review each of the following sections carefully. Thank you for selecting Peak Scientific to meet your Gas Detection needs, and should you require any further assistance or support please do not hesitate to contact Peak Scientific or Peak Partner from which you purchased your Detector. Page 3 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual Introduction The Peak Scientific Hydrogen Detector is an extractive gas sampling system that draws a sample locally from your GC Oven to a sensor cartridge that is located inside the detector’s chassis. Our Hydrogen Detector is wall mountable and displays gas concentration, alarm, fault and status information via its backlit LCD and LEDs. A simple to use 4-button keypad located under the display provides the facility to set-up, review, operate and make changes to the detector’s configuration.

Page 9 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual Unpacking Although Peak Scientific takes every precaution with safe transit and packaging, it is advisable to fully inspect the unit for any sign of transit damage. Check ‘SHOCKWATCH’ label for signs of rough handling prior to un-packing – Any damage should be reported immediately to the carrier and Peak Scientific or the Peak Partner from where the unit was purchased. Please save the product packaging for storage or future shipment of the Detector. Note: Included with the Detector is a “Fittings Kit” containing the communication cable for connecting the detector to the generator also all the required fittings. Be careful not to discard these with the packaging. Page 10 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual Installation Detector Environment The Detector is designed for use indoor safe non- explosive atmospheres only. It should be installed at a suitable height adjacent to the Gas Chromatograph it is connected to. Please see the Tubing lengths section for further details on maximum distances from the GC for maximum performance of the detector. Performance of the Detector (like all sophisticated equipment) is affected by ambient conditions. Note should also be taken to the proximity of Air Conditioning outlets. These can sometimes give rise to “pockets” of air with high relative humidity. Operation of the unit within such a pocket could adversely affect its performance. Please refer to the drawing below for the general dimensions of the unit. Maximum Ambient Conditions: 40°C (dry bulb) 90%RH (Max) Non-Condensing Location The detector can be located on a flat surface or wall mounted for operation this will ensure that you can locate it within the maximum distance required for the unit to successfully monitor for Hydrogen leaks. The Peak Hydrogen Detector is supplied with a bracket to allow a simple way to mount the unit to a wall near the GC. Use 2 x M4 Screws or equivalent (not supplied) for mounting the bracket to the wall. You will then be able to lower the detector unit onto the wall bracket. The wall mounting has been specially designed to allow greater serviceability by enabling the unit to be taken down off of the wall for service and maintenance work to be carried out, without having to remove the wall bracket. Page 11 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual General Dimensions The Detector must always be placed on a level surface. Failure to do so will affect the performance of the Detector.

First remove the plastic cover on the top of the GC. 2. Locate the cut-out hole on the aluminium plate directly above the rear hole on the GC oven. 3. Make a hole through the insulation material, through to the oven. The stainless steel tubing from the detector can now be pushed through the hole, and secured in place using more insulation material. 4. Once the stainless steel tubing has been pushed through and secured, the end of the tubing should be aimed at the inlet of the GC column. Page 14 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual 5. Position the end of the tubing as close to the inlet as possible, without limiting access for column changes and inlet maintenance. 6. The detector is now fully connected and will take samples continuously and both the detector and the H2 generator will sound an alarm if dangerous levels of Hydrogen are detected. The generator will then shut down. Tubing Lengths The length of the tubing which will be connected to the Input Port of the Detector is important and is determined by the Hydrogen cartridge used by the detector. Failure to follow these recommendations could lead to the Hydrogen Detector failing to operate efficiently. Inlet Sample Specifications: Maximum Tubing Length, m (ft.)

This unit is plugged, from the ‘In’ port at the rear on the detector, into the ‘H2 Detector’ port at the rear of the generator, as shown below. This connection will provide the detector unit with power and allows communication between the Precision 500 and the detector unit. The detector will take samples continuously and both the detector and the Precision 500 will alarm if dangerous levels of hydrogen are detected, the Precision 500 will then shut down. Multiple detectors can be connected to one Precision 500. If this is desired, connect the first detectors ‘Out’ port to the second detectors ‘In’ port, as illustrated below. Please take into consideration when working with multiple Hydrogen Detector Units that a minimum required distance between units is 82mm (3.23in). Precision 500 H2 Detector In Port Out Port H2 Detector Port Page 16 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual Sensor Cartridge Installation The pre-calibrated smart sensor cartridges can easily be fitted or replaced as they simply plug into the detector without the need for any tools. The sensor cartridge is firmly held in place by two locking tabs. Some cartridges are shipped with a protective cap to shield them from contaminants during shipping. This cap must be removed before inserting the cartridge into the Detector unit, failure to do so may damage the transmitter. Switch the power switch on the terminal module to the ‘on’ position and the re fit the Sensor warranty is void if the sensor cartridge is opened by unauthorised user. *The cartridge has an ‘activate by’ date that must be adhered to. Page 17 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual In a first-time start up, an F49 or F88 fault code may be displayed; there is no actual fault and the fault message can be cleared by depressing the “X” button for a few seconds. To properly activate the Detector with the cartridge for the first time: 1. 2. 3. 4. 5. When “ChAngE gAS” or “FIrSt CELL” scrolls on the display, hit the on “✓” the Detector front panel. When the “reboot” completes then press and hold the “X” to clear any latched fault(s). Confirm that the green LED is flashing. Confirm that the yellow and red LEDs are off. Confirm the display shows a concentration of zero (as appropriate). The cartridge has now been accepted by the Detector as the correct type. If the above steps were not performed at initial start-up, the remove the cartridge and cycle power. Once the Detector has completed the “reboot” process, install the cartridge and repeat the steps above. Page 18 2013 © Peak Scientific – Rev 4 – 03/09/1 H² Detector User Manual Start-up Sequence CHECK: 1. Ensure power cable is correctly connected between the Hydrogen Generator and the Hydrogen Detector. 2. Hydrogen Generator is turned on. 3. After applying power to the Peak Scientific Hydrogen Detector the unit will run go through a start-up test routine illuminating in sequence all LEDs, icons and digits of the display. The unit will then display the messages “WAIT” and “LOAD” as it checks for the cartridge data, typically less than 180 seconds. 4. When complete, the detector will enter normal monitoring mode indicated by the icon on the display cycling through three states (2 rings, 3 rings, 4 rings). The measured gas concentration will be shown on the display. The green LED will flash once every second indicating power and the sample flow rate indicator will be displayed. If monitoring is interrupted due to a fault, a test or calibration process or a user requested inhibit, the display will flash, please refer to the Troubleshooting section for guidance.
