Like all fiber optic modems, the Model 1110 is inherently immune to RFI/EMI noise, ground loops and transient surges. The carrier may be switch selected as either “Continuously On” or “Controlled by RTS”, while an easily accessible DCE/DTE switch eliminates the need for cumbersome RS-232 crossover cables. Two easy-to-read LED indicators monitor the status of carrier detect and fiber optic output. Drawing all necessary power from the RS-232 interface, the Model 1110 requires no AC power or batteries to operate.

DESCRIPTION AND USAGESee Table 1 for kit contents. This kit is designed for use in the furnaces listed in Table 2. To accommodate many different furnace models, more parts are shipped in kit than will be needed to complete conversion. When installation is complete, discard extra parts.INSTALLATION1.Set room thermostat to lowest setting or “OFF”2.Disconnect power at external disconnect, fuse orcircuit breaker.3.Turn off gas at external shut−off or gas meter.4.Remove outer doors and set aside.5.Turn electric switch on gas valve to OFF.MANIFOLD/ORIFICE/BURNER REMOVAL1.Disconnect the gas pipe from gas valve and removepipe from the furnace casing. See Figure 1. NOTE: Use a back−up wrench on the gas valve to prevent the valve from rotating on the manifold or damaging the mounting to the burner box. See Figure 2 and Figure 3.2.Disconnect the connector harness from gas valve.Disconnect wires from Hot Surface Igniter (HSI) andFlame Sensor. Disconnect the two wires from theLow Gas Pressure Switch (LGPS) located on thegas valve.3.Support the manifold and remove the 4 screws thatsecure the manifold assembly to the burner box andset aside.4.Note the location of the green/yellow wire groundwire for re−assembly later. See Figure 2.REPRESENTATIVE DRAWING ONLY, SOME MODELS MAY VARY IN APPEARANCE.A170154Figure 1 −Representative Furnace Drawing235.Slide one −piece burner assembly out of slots on sides of burner box.6.Remove the flame sensor from the burner assembly.See Figure 3.7.Remove the orifices from the manifold and discard.Gas valve must be installed onmanifold with minimum engagement of 6threads Cross threading is not˚+ or -2˚C L Gas valve is parallel to manifold within + or - 3˚A11407Figure 2 − Manifold AssemblyA11403Figure 3 − Burner AssemblyORIFICE SELECTION/DERATEA96249Figure 4 − Burner OrificeDetermine natural gas orifice size and manifold pressure for correct input at installed altitude by using Table 3.1.Obtain yearly heat −value average (at installed altitude) for local gas supply.2.Obtain yearly specific −gravity average for local gas supply.3.Find installation altitude in Table 3.NOTE : For Canada altitudes of 2000 to 4500 ft., use U.S.A. Altitudes of 2001 to 3000 ft. In Table 3.4.Find closest natural gas heat value and specific gravity in Table 3.5.Follow heat −value line and specific −gravity line to point of intersection to find orifice size and manifold pressure settings.Furnace gas input rate on furnace rating plate is for installations at altitudes up to 2000 ft. (610 M).In the U.S.A .; the input rating for altitudes above 2000 ft.(610 M) must be reduced by 2 percent for each 1000 ft.(305 M) above sea level.In Canada , the input rating must be derated by 5 percent for altitudes of 2000 ft. to 4500 ft. (610 M to 1372 M) above sea level.The Conversion Kit Rating Plate accounts for high altitude derate.INSTALL ORIFICES1.Install main burner orifices. DO NOT use Teflon tape.Finger −tighten orifices at least one full turn to prevent cross −threading, then tighten with wrench.2.There are additional size orifices for different heat content gases. Discard extra orifices.NOTE : DO NOT reinstall the manifold at this time.REMOVE MIXER SCREWS FROM THE BURNERSNOTE : Each burner contains a mixer screw that must be removed. Refer to Figure 5 for the mixer screw location.1.Remove the mixer screws from the burners.NOTE : It is not necessary to plug the hole in the burnerwhen the mixer screws are removed.A11501Figure 5 − Mixer Screw LocationREINSTALL BURNER ASSEMBLY To reinstall burner assembly:1.Attach flame sensor to burner assembly.2.Insert one-piece burner in slot on sides of burner boxand slide burner back in place.3.Reattach HSI wires to HSI.4.Verify igniter to burner alignment.

第五章 ADS1110操作指导书
O 建议 C ADS1110由小型低电压工艺构造而成。模拟输入设有对电源具有保护功能的二极管，然而这些
二极管的电流控制能力受限制，而且如果模拟输入电压维持在高于满幅度300Mv， 则会对ADS1110造
. 成永久性的损害。防止过压的一种方法是在输入线上加限流电阻。ADS1110的模拟输入可承受最大 E 10mA的瞬间电流。

15章 水电制氢控制系统
第十五章水电解制氢自动控制系统第一节水电解制氢干燥装置自动控制系统成水电解制氢及干燥装置的自动控制系统一般地,是由本地上位数据管理机、制氢控制柜、动力柜及现场控制仪器、仪表等组成,由此完成水电解制氢及干燥装置的系统控制及运行数据管理。
装置的各个运行数据是由安装在制氢控制柜内的可编程序控制器（PLC）进行采集、处理，并通过通讯网络与上一层的计算机管理系统进行数据交换，其组成方框图如下：1.1 现场自控仪器、仪表水电解制氢及干燥装置所用的现场自控仪器、仪表按位置可分为四个部分:框架1，即制氢及干燥装置主体，包括电解槽槽体、气液分离器、氢气洗涤器、碱液循环泵、氢气干燥塔（A塔及B塔）、冷却器等；框架2，即产品氢配气装置，经干燥后合格的产品氢气经此装置进入氢气储罐或向发电机组补氢；框架3，包括原料水箱、碱液箱及系统加水泵；氢气储罐等。
（1）框架1：本部分的自控仪器、仪表主要有以下四类：变送器：包括压力变送器、差压变送器（氢液位变送器及氧液位变送器）、铂电阻等。
装置的工作压力经压力变送器后变成4~20mA的电信号传送到制氢控制柜；两套差压变送器分别把氢气液分离器中的氢液位及氧气液中的分离器中的氧液位变换成标准的4~20mA信号传送到制氢控制柜；铂电阻共有五支，一支用来测量装置运行时循环碱液的温度。
170两支分别用来测量干燥A塔和干燥B塔的上部温度，还有两支分别用来测量干燥A塔和干燥B塔的上部温度信号全部送入制氢控制柜。
●执行器：包括有三个气动薄膜调节阀及七个气动球阀。
●检测仪表：包括氢中氧分析仪、氧中氢分析仪及氢气露点仪等。
●防爆电接点压力表或压力开关：一般设置了两块压力表，其中一块用来检测装置运行时的氢阀后压力，当氢阀后压力超过了报警设定值时，氢阀后压力超限报警信号即送入制氢控制柜内；另一块作用是，当自动控制系统失灵时，用来检测装置运行时的系统压力，并由此发出联锁信号直接传送给整流柜，切断整流柜的输出电流，起到二次保护的作用。

Current flowing through the coil generates axial movement of the coil and flexure. The flexure moves against the end of a nozzle, and creates a back pressure in the nozzle by restricting air flow. This back pressure acts as a pilot pressure to an integral booster relay.Consequently, as the input signal increases (or decreases, for reverse acting), output pressure increases proportionally.Zero and span are calibrated by turning easily accessible adjusting screws on the front face of the unit. The zero adjustment causes the nozzle to move relative to the flexure. The span adjustment is a potentiometer that limits the flow of current through the coil. A thermistor circuit in series with the coil provides temperature compensation.MOUNTINGThe transducer can be mounted at any angle, but should be calibrated after mounting. For maximum output pressure stability, it should be mounted vertically in a vibration free location or such that the vibration is isolated to the X and Z axis as shown in Figure 3.Pipe:Due to its light weight , the transducer may be sup-ported by the piping used for the supply and output.Panel:(with access to rear of panel) Attach transducer (See Fig. 3), to panel using two 10-32 screws and two threaded mounting holes on the back of the unit.Panel:(with no access to rear of panel) Attach bracket (see Fig 1 and 3), to transducer using two 10-32 screws on the back of the unit and mount bracket to panel using four 8-32 screws.AIR CONNECTIONS •Supply Air must be instrument quality air regulated between the minumum and maximum specified on the nameplate of the transducer.•Instrument quality air consists of :a A dew point less than 35˚Fb No particles larger than three micronsc Maximum oil content of 1 ppm •All unused ports must be plugged.Supply:Connect supply to the1/4" NPT ports marked “IN” on the base of the transducer. Avoid getting pipe sealant inside the piping or transducer.Output:Connect output to the 1/4" NPT ports marked “OUT” on the base of the transducer. The pipe plugs may be removed from the two auxiliary output ports for a pressure gauge or as an alternative output port.3Figure 1EN 50081-1 (1992): Test results confirmed that no precautions need to be observed during installation regarding electro-magnetic emissions from the I/P & E/P 211 Transducers.EN 50082-1specifications for the Transducers. The input wiring to the transducer should be isolated from other high voltage transient wiring. The momentary switching on and off of nearby relays, motors, or other high capacitive or inductive loads can have a minor effect on the terminal based linearity specification (1.0% of span, standard range models). Any change in output pressure is minimal and momentary, and is considered to be within its performance capabilities. Use of a ferrite bead collar on the input wires entering the transducer is recommended should installation next to high electromagnetic interference beCALIBRATIONOnce the transducer has been mounted, and air supply connections finished, the unit’s calibration must be checked before placing into service.Note: input percentage refers to the following examples:5Forward Acting1. Apply the 0% input signal to unit and adjust the “Zero” adjusting screw to the low setpoint output. Turn screw counter-clockwise to increase output. If there is no change in output, keep turning adjustment screw counter-clockwise until output begins to rise. It is imperative that the output pressure be closely monitored as turning the zero screw excessive-ly could damage the flexure.2. Apply the 100% signal to unit and adjust “Span” adjusting screw until output is at the high setpoint.3. IMPORTANT: On I/P (Current) input models, turn the “Span” adjusting screw counter-clockwise to increase output. OnE/P (Voltage) input models, turn the “Span” adjusting screw clockwise to increase the output pressure.4. Repeat steps 1& 2 until unit is calibrated.Reverse Acting1. Apply the 0% input signal to unit and adjust "Zero" adjusting screw until output reaches the high output pressure set-point. Turn counter-clockwise to increase.2. Apply the 100% input signal to unit and adjust "Span" adjustment until output pressure is at the low setpoint.IMPORTANT:On I/P (Current) input models, turn the “Span” adjusting screw clockwise to increase output. On E/P (Voltage) input models, turn the “Span” adjusting screw counter-clockwise to increase the output pressure.3. Repeat steps 1& 2 until unit is calibrated.SIGNAL IMPEDANCE6BLACK121 Ω300 ΩI / P SCHEMATICFIGURE 2BLACKWHITE121 ΩCOIL 300 ΩE / P SCHEMATICThe input impedance will vary depending upon the potentiometer setting of the “SPAN (RV1)”, (SEE FIG. 2). The I/P circuit design consists of a resistor and potentiometer in parallel with the coil/flexure. The E/P circuit utilizes a potentiometer in series with the coil/flexure. The following are some of the nominal impedences that would be measured across the signal leads of the average calibrated transducer. These values are helpful when determining power requirements and for trouble-shooting.TROUBLESHOOTINGNote:If you experience an unusual problem that is not described in this section, or if troubleshooting procedures will notrestore the unit to normal operation, please contact Omega.78Figure 3OMEGA’s policy is to make running changes, not model changes, whenever an improvement is possible.
