This setting will give the bestcrimp on most wires. Two other adjustment settings areavailable: S, the smallest configuration and L, the largestconfiguration.3.Crimp a terminal or connector and inspect the insulationsupport sleeve crimp or configuration. A properly crimped sleeve snugly grasps the wire insulation.4.If the crimp configuration is too loose, change the adjustment setting by removing the air powered crimp toolhead from the AT-200 and setting adjustment screw to the S position. Re-insert the air powered crimp tool head into the AT-200 and crimp, and inspect the insulation support sleeve.5.If crimp configuration is too tight, change adjustment setting by removing the air powered crimp tool head fromthe AT-200 and setting adjustment screw to the L position. Re-insert the air powered crimp tool head into the AT-200 and crimp, and inspect insulation support sleeve.3.3 Insulation Support Crimp Adjustment(Newer style jaw air powered crimp tools)For the new style crimp head tools, if the insulation part of the crimp needs to be adjusted, first loosen the M4 screw on the bottom tool jaw, then insert a 3/32” Hex wrench (supplied) into the bottom of the lower die. See Figure 3.1. A clockwise (CW) rotation decreases the insulation crimp while a counter-clockwise (CCW) rotation increases the insulation crimp. After adjusting retighten the M4 screw.3.4 Terminal CrimpingSpecifications and Instructions for crimping are included with the individual air powered crimp tool heads.3.5 MaintenanceCAUTION: Always disconnect air supplybefore all maintenance.It is recommended that each operator of the toolbe made aware of, and responsible for, thefollowing maintenance steps:1.Remove dust, moisture and othercontaminants with a clean brush, or soft,lint-free cloth.2.INSULATION CRIMPING3.Make certain all pins; pivot points and bearing surfaces are protected with a thin coat of high quality machineoil. Do not oil excessively. This tool needs cleaning and lubrication for a maximum service life of trouble-free crimping. Using a light oil, such as 30 weight automotive oil on the oil points shown in Figure 3-5, every 5,000 crimps or monthly will significantly enhance the tool life and ensure a stable calibration.4.When tool is not in use store the tool in a clean, dry area.3.6 WarrantyThis tool is for electrical terminal crimping purposes only.

INTRODUCTION:The 4-20mA Transmitter is designed to operate over 90º, 180º, 360º (option dependent) rotation with ± 5° of over-travel at each end. The Transmitter is direct acting, reverse acting and is also suitable for split ranging (typical setting: 4-12mA or 12-20mA). Position feedback is accomplished through a precision potentiometer that is conductive resin and environmentally sealed. The Triac transmitter features a non-interactive zero and span for easy one step calibration.INSTALLATION:A.Attach proper actuator mounting kit to the transmitter housing using the M6x8 socket head cap screwsprovided.B.Align the switch output shaft to the top of the actuator accessory output shaft and engage the two shaftstogether (or use coupler with non-ISO/NAMUR actuators).C.Attach the bracket assembly to the actuator but do not tighten. Stroke the actuator to allow thetransmitter and actuator to self-align.D.Tighten the transmitter assembly on to the actuator. Note: Steps 3 and 4 can be done prior to calibration. CALIBRATION:A.First select the ‘Action’, direct or reverse. This is accomplished through the location of thepotentiometer ribbon connector plug. Brown wire to ‘D’ for direct or brown wire to ‘R’ for reverse.Factory default setting is ‘D’B.Wire output (+ and -) of transmitter to a regulated current source such as Transmation TM, Altek TM, orFluke TM, meter.C.Operate valve to 50% position (45°). The large spur gear is attached to the drive shaft with a setscrew.Loosen setscrew to disengage the gear. Rotate small spur gear on potentiometer until 12mA is visible on meter. Re-engage large spur gear and tighten the setscrew.D.Rotate actuator closed and turn zero potentiometer (clockwise for higher and counter-clockwise forlower) until meter reads 4mA.E.Rotate actuator open and turn span potentiometer (clockwise for higher and counter-clockwise forlower) until meter is at 20mA.F.For split ranging follow steps 3, 4 and 5 setting zero and span to proper split range: 4 to 12mA or 12 to20 mA.G.Important Note: Disconnect test equipment supply power prior to removing test meter wiring (thetransmitter has CMOS circuitry and is sensitive to voltage/current surges).H.The transmitter is ready for field wiring. Note: If more than one current device is in the loop with thetransmitter, they must be wired in series. Damage may occur if wired incorrectly.SHIELDING:The transmitter is a sensitive precision instrument and if not properly wired is susceptible to intrinsic noise.This could include EMF from inductive loads or RFI from wand held radios.A.The size of wire is dependent on the length of run, it is recommended to use no less than 18 gaugeshielded wire.B.The shield should only be grounded at one end (preferably the source). This acts as an antenna anddirects all noise to ground.TROUBLESHOOTING:1. Problem:Output not continuous throughout actuator/valve stroke (experience a band of max. output).Probable Cause/Solution:Potentiometer out of adjustment (see calibration steps 3 through 9).2. Problem:Transmitter does output 4 or 20mA at desired end of travel.Probable Cause/Solution:Zero or span trim potentiometer is out of adjustment (see calibration steps 4 and 5).3. Problem:Transmitter module has no current signal or provides a constant signal.Probable Cause/Solution:Circuit Board LED not lit:1. Loose or shorted signal connection (no loop power)2. Controller board not responding (replace board).3. Check control sourceCircuit Board LED lit:1. Potentiometer disengaged2. Defective potentiometer or controller board (replace).3.

（迁移或者调零）7、进水，起雾：●变送器壳体的前后盖是否拧紧;●电缆线应该由下而上引入变送器电缆接头处；●变送器表头应该垂直向上，传感器部分应该垂直向下（可以有一定的倾斜角度尽量垂直）●变送器不能安装在有蒸汽能够直接喷射到的位置，应采取隔离措施；●对于已经进水的变送器应立即拆下电路板将水擦干并烘干；8、法兰表清零开始使用后短时间内表头变为负值：●在密码管理项输入“050110“取消ZSC功能●是否有带压清零，应取消零点校准功能；9、加压无反应：●引压管堵；●量程设置错误；●被测介质的粘度太大，流动性差；●传感器故障；●在对大气的情况下，检查SUB 10的no.0项值如果大于0.2则表明传感器存在故障；10、室外低温环境下使用：●尽量采用垂直安装方式；●当环境温度过低时须加伴热（不低于零下40℃）；11、高温环境下使用：●介质温度较高时必须采取隔离措施（加隔离液、冷凝罐等）；●环境温度较高时应有防护措施远离高温源（环境温度不高于80℃）12、测量差压时输出最大或最小：●H/L端其中一端有堵或微漏；●H/L端接反;●如果电流低于3.9mA或高于21mA，主板电路有故障；●三阀组阀门故障；13、汽包水位调试●测汽包水位时通常为负迁移表，调试时需要将L端灌满水将4mA校准；13、流量测量注意事项●测量蒸汽流量时，取压口应开在管道侧面，变送器安装位置应比取压口低。
