Size is properly adjusted when the earcups are centered over the ears. It is important to make the same adjustments to both sides of theheadband to keep the headband andpad properly centered over the head.Comfort Cam™ADJUSTMENT KNOB SETTINGS Headband Pressure Adjustment There are three pressure settings for headband comfort. Increasing thepressure will improve the seal between the earcup and the head for greaternoise reduction. To change the pressure setting, remove the headset and fold the earcup inward as shown, then rotate the Comfort Cam adjustment knob to the desired setting. Repeat for both earcups.Both sides of the headband should be set to the same pressure setting to keep the headband properly centered on the head.Figure 1Headband Size AdjustmentFigure 2Headband Pressure AdjustmentLeft or Right Side Microphone Placement 1.Rotate the boom as shown.2.Reshape the boom so that the microphone will be at the corner of the mouth.Figure 3Rotating and Reshaping the BoomConnectionConnect the headset to the aircraft radio or intercom system as shown in Figure 4.Figure 4Echelon 25XT Connectors Stereo Mono SwitchThis switch is located on the Y-cord (Figure 4). Set the switch to stereo for aircraft with a stereo intercom system. Set the switch to mono for monaural intercom systems or for direct connection to the aircraft radio.Cellphone/Audio InterfaceThe Echelon 25XT includes a unique amplified interface allowing for the connection of a cellular telephone and an audio input simultaneously. This configuration allows the user to set up before take-off and eliminates the need to re-configure cords and equipment when operating the aircraft.The other unique feature of this interface is the ability to obtain power from the aircraft’s possessive communications system. This featureresults in increased battery life for the ANR system while maintaining the benefits of an amplified interface. By amplifying the inputs, the Echelon 25XT allows the user to adjust volume level at the headset contributing to the ability to not need re-configuring while in flight.The Telex Echelon 25XT cell phone/audio interface has been designed to function with the widest array of cellular telephones and portable audio devices. There are cell phones and audio devices on the market notdesigned to industry physical and electrical standards. These devices are not guaranteed to function properly with the Echelon 25XT headset.Please see the Telex web site for additional information./aircraftFigure 5Mic Gain AdjustmentMicrophone Gain Adjustment The microphone gain has been factory-adjusted to the nominal level required for aircraft use and should normally not require readjustment. Readjustment by a qualified avionics technician is recommended. To access the gain trimmer, insert a small flat-blade screwdriver through the access hole in the mic element (Figure 5). Clockwise rotation of the trimmer increases gain.Ear Cushion ReplacementTo remove an old ear cushion, simply grasp it and pull it off the earcup.To install a new ear cushion, start at the top of the earcup. Place the flap on the back of the ear cushion over the lip along the top of the earcup.Then pull the bottom of the ear cushion down over the lip at the bottom of the earcup.Figure 6Mic Element Removal for ReplacementMic Element RemovalPress the release catch on the microphone element, and carefully pull out the element.Avoid pulling the microphone wires. Pull on the plasticconnector housing to unplug the microphone element.Volume AdjustmentWhen the microphone is worn on the left side, volume is increased by rotating the top of the volume controls clockwise. Control operation is reversed when the microphone is worn on the right side.SpecificationsReceiversType: DynamicImpedance: Accepts 150-600 ohm sourcesFrequency Response: 350 Hz - 3.0 kHz ± 6dBSensitivity: 90 ±5 dB SPL for 1 mW, 1 kHz inputMaximum Power Input: 30 mWMicrophone/Amplifier AssemblyMicrophone Type: Noise-canceling electret condenserOutput Impedance: 50 ohms (designed for radio input impedances from 50-600 ohms)Frequency Response: 100 Hz - 3.5 kHzSensitivity: -50 +/-6 dB (ref: 1V/ µbar)Operating Voltage: 8-16 VdcCords and PlugsCord: 5.5 ft (1.7 m) “Y” cord with stereo/mono selector switch Receiver Plug: 1/4" stereo phone plugMicrophone Plug: PJ-068 equivalentt s i Ls t r aPm e t I.o N.oNt r aP no i t p i r c seD y tQ1226548daPdaeHt nemeca l peR1 2073695p i l Cd r oC1 3016318y l bmes sAt neme l Eenohpo r c iM1 4126548)2f ot es(sdaPr aEmaoF1 506548nee r c sdn iW1 609EMC esaCgn i y r r aC1TELEX COMMUNICATIONS, INC. - LIMITED WARRANTY Uniform Limited Warranty: Telex branded products are warranted by Telex Communications, Inc. against malfunction due to defects in materials and workmanship for a specified period, as noted in the individual product line statements below, beginning with the date of original purchase by the end-user.

When used with a TEGAM Model 252, 253, or 254, it provides either a “GO”, “HI”, or “LOW” indication for R, L,C, or G. The Model 1412B simultaneously sorts for D and C, so there is also a “D HI”indication for this condition.Using the 1412B speeds sorting andminimizes component handling. One method of the acceptance indication is through a rear panel connector which allows for integration into a system by connecting the 1412B to automatic handling equipment.The other indication method is the front panel LED’s. There is also a gated mode,where a comparison is initiated by a control switch and held for an adjustable time, up to two seconds, after release of the switch.Both these features simplify manual use.Resolution of the nominal value is 4.5digits and the limits switches have three digit resolution. The system has two limits ranges,10% and 100% of full scale, allowing for range settings of 0 to 9.99% or 0 to 99.9%.The D limit also has two ranges. The upper and lower limits are set independently,which adds to the outstanding flexibility and accuracy of the system.the relay contacts remain open when a limit is reached, unless closure is initiated by a control switch. Duration of closure, after the control switch is released, is determined by the adjustment of a timing control (two seconds maximum).Input SignalsC, L, R, G analog; D analog; analog common.Internal reference voltage used with TEGAM Model 252, 253, 254 or other instruments,selected by rear panel switch.DimensionsHeight 13.5 cm (5.3 inches)Width 21.6 cm (8.5 inches)Depth (overall) 33 cm (13 inches)Weight3.63 kg (8 lbs) net.Standard EquipmentInterconnection Cable 42855 Instruction Manual for 1412B 42428Options and AccessoriesBattery Powered 252SP2596Battery Powered 253SP2598Battery Powered 254SP2599Dust Cover 43374Sorting Fixture 2001Cable Set for 200143586LINE VOLTAGE 10250/60 Mz100/120220/240FUSE SIZE 1/2A1/4A UNLATCHCalibration & Technical ServicesFor warranty and remedial repair, calibration services and spare parts, or for additional information on TEGAM sales and service offices around the world, contact us at 440-466-6100 (ph) or 440-466-6110 (fx).252.991PGTHE GLOBAL SOURCE FOR PROVEN TESTAND MEASUREMENT TECHNOLOGY.TEN TEGAM WAY • GENEVA,OHIO 44041440-466-6100 • FAX 440-466-6110 • e-mail:***************。

tank cleaning•High-impact cleaning in a 360° repeatable cleaning pattern •Cleaning process can be validated using Alfa Laval Rotacheck Standard DesignThe choice of nozzle diameters can optimize jet impact length and flow rate at the desired pressure. A 2.1 material certificate and an ATEX certification are available.Alfa Laval offers a wide range of tank cleaning machines suitable for different duties and industries. An alternative that offers performance similar to the Alfa Laval MultiJet 25 is the Alfa Laval GJ PF , which is ideal applications that require a small tank inlet opening.Working principleThe high-impact jet stream from the Alfa Laval MultiJet rotary jet head covers the entire surface of the tank interior in a successively denser pattern. This achieves a powerfulmechanical impact with a low volume of water and cleaning media.The flow of the cleaning fluid makes the nozzles perform a geared rotation around the vertical and horizontal axes. In thefirst cycle, the nozzles lay out a course pattern on the tank surface.The subsequent cycles gradually make the pattern denser until at full cleaning pattern is reached. Once the full cleaning pattern is reached, the machine will start over again and continue to perform the next full cleaning pattern.Certificates2.1 material certificate and ATEX.TECHNICAL DATAMax. throw length:9 - 14 mImpact throw length: 4 - 8 mRecommended pressure: 5 - 6.5 barCleaning PatternFirst cycle Full patternThe above drawings show the cleaning pattern achieved on a cylindrical horizontal vessel. The difference between the first cycle and the full pattern represents the number of additional cycles available to increase the density of the cleaning.PHYSICAL DATA1 FDA compliance 21CFR§177Max. ambient temperature:140 °CCautionAvoid hydraulic shock, hard and abrasive particles in the cleaning liquid, as this can cause increased wear and/or damage of internal mechanisms.

Any liquids or debris that may fall into this area when doors are open should be immediately wiped with a dry cloth, and keep this area clean at all times.Do not allow the spillover trays to over ﬂ ow, and do not allow full trays to splash over edge when cleaning. Spillover debris and liquids can be hot and cause burns, and/or damage to the internal operation of the grill.OPERATOR INSTRUCTIONSA f f i n i t y25ECOOK SURFACE MAINTENANCERegular cleaning and care for your Evo Afﬁ nity 25E cooktop will keep it looking and functioning it’s best.The cook surface is designed to hold a ﬁ ne layer of cooking oil creating a ‘seasoning’ on its surface. Thisseasoning promotes a non-stick cooking surface and is easily maintained.Caring for Evo’s cook surface is much like maintaining cast iron cookware. When the surface requires cleaning,there are a few basic cleaning techniques to use. For quick and routine cleaning between preparations, a metalspatula or scraper works for removing the majority of surface debris. For tougher areas or where sugars glazethe cook surface, pour a small amount of warm water on the soiled surface while the grill is warm and scrape thedebris away with a spatula. Heat the cook surface to a high temperature and allow the sticky debris to becomebrittle. Once the debris is brittle, use the spatula or scraper to remove it. Afterwards wipe the cook surface with vegetable oil again before cooking.To condition the Evo cook surface you should use the grill cleaning kit supplied with your grill. The grill cleaning kit contains a blue grill pad handle, grill cleaning screens, and grill grey polishing pads. Use the polishing pad afterthe grill cleaning pads to achieve a smooth cooking surface for the most delicate foods and applications.To use a grill cleaning screen: With a warm cook surface, place one gray polishing pad between the grill handlebase and the grill screen, so the grill screen makes direct contact with the cooking surface. Pour a small amountof vegetable oil on the cook surface and scrub the surface in a circular motion. The gray polishing pad allowsexcess oil to be absorbed and scours the cooking surface of carbonized debris. When ﬁ nished scrubbing, wipethe surface down with a paper towel or cotton terry cloth.The drip pan located just below the cook surface is designed to catch food debris and drippings from the cooksurface. We recommend cleaning the drip pan after your grill has cooled to prevent the possibility of touchinghot adjoining surfaces. The drip pan is easy to wipe out with soap and water using a kitchen sponge. For added convenience, two removable stainless ninth-pans are mounted inside doors at right and left side of the front control panel for collecting drip pan debris and spill overs. These spillover trays can be easily washed by hand or in a dishwasher. Be sure to empty the spillover trays after every use, and at a minimum, whenever they appear halffull.All the stainless steel components on your grill can be easily polished using a stainless steel cleaner/polish. Information about purchasing replacement grill cleaning and polishing pads is available on our Website. The Evoweb site address is: .Cooking TechniquesStovetop Cooking and Heat ZonesYou can use Evo’s cook surface similar to the burners on your kitchen stove top. Adjust Evo’s heater elements to control the temperatures of the cook surface “heat zones.” Evo’s circular grill top is divided into two distinct zones.The center control panel knob controls the “inner heat zone,” which is also the inner circle of the cook surface at approximately an 11” radius from the center of the cook surface. The outer control panel knob controls the “outerheat zone,” which is the outer circle of the cook surface. Because the cook surface is made of heavy steel, it takes approximately 10 minutes from a cold start to completely heat the surface. With a pre-heated cook surface, if youadjust one of the heater elements, you will have to wait momentarily before the heat zone adjusts to temperature.Thank You For Cooking With Evo!INSTALLATION INSTRUCTIONSA f f i n i t y 25EEvo, Inc. | 8140 SW Nimbus Ave., Bldg 5 | Beaverton, Oregon 97008 USAPhone503.626.1802|Fax503.213.5869||**********************2130AMP ELECTRICAL SCHEMATICPART #: 10-0062-EL & 10-0061-EL 208V - 230V, 1-Phase, 50-60Hz 30AMP Dedicated Circuit 208V / 5.37 kVA。

4、主要结构特点
该低温组合安全阀是一种新型的贮运设备配套用组合阀，它是由一只三通球阀、两只安全阀、两只防爆装置和两只排液阀组成。

它属于贮运设备的安全保护系统，对贮槽起安全保护作用，代替了以前贮槽所配用的三通截止阀、安全阀、防爆装置。

将三种阀门的功能组合在一起，通过三通球阀的多用连接法兰连接。

减少了管路的焊接。

介质进气口改以前的法兰连接为插焊或对接焊，减少了介质漏点。

其中该组合安全阀的主要组件三通球阀采用了特殊的阀杆设计来防静电，三通球阀的阀体及多用连接法兰由以前的铸件毛坯现改为精锻件，
增加了它的防爆功能。

安全阀选用的是全启式结构，增加了它的排量，使该组合阀的安全性大大提高，并且使用寿命也大大提高。

5、工作原理
本组合安全阀主要通过它的主体阀三通球阀来控制它的开启，在球阀上开有T型通道。

正常工作时，手柄处于中间位置，T型通道的位置为“┯”字型，介质由进口进入左、右两边通道，这时左、右两端的安全阀及防爆装置同时工作；当右边安全阀或防爆装置出现故障时，手柄由中间向左边转动90°，球体T型通道的位置为“┨”字型，进口与左边安全阀和防爆装置相通，使它处于工作状态，这时可以对右边的安全阀或防爆装置进行检修；当左边安全阀或防爆装置出现故障时，手柄由中间向右边转动90°，球体T型通道的位置为“┠”字型，进口与右边安全阀和防爆装置相通，使它处于工作状态，这时可以对左边的安全阀或防爆装置进行检修。

在手柄上设计了一个“┯”字型开槽，它随着手柄转动，与球体的T型通道一致。
