34、峰值电压会对毁坏它。好的隔离变压器可以在峰值电压出现时对仪表起到保护作用。all supply connections to final control devices such as contactors, solenoids etc. must be taken directly from the supply and not from the supply terminals of the instrument.所有与电源连接的控制设备比如电流接触器，螺线管等，必须直接从电源接出，而不能从仪表的电源终端接出。earthing:接地：an effective earth is mandat

38、定值和控制参数（针对监控者），配置和校准。the manual covers all aspects of operation of the instrument. please read instructions carefully before altering any programming or configuration information.手动可以对仪表进行各种操作。在改变程序或配置信息前仔细阅读说明书。2. operation 操作2.1 power supply 电源before connecting power to the instrument ensure that

39、you are connecting right input voltage to terminal (check test report or tag detail on instrument for operating power supply). the instrument is having jumper selection on power supply card for 110vac/ 230vac selection. on application of proper power, the instrument will display input type for two s

40、econds.在连接仪表电源前要确保它连接的电压端子正确（打开电源时要检查测试报告或仪表上面的标签）。仪表的电源卡可以在110vac/230vac两者中选择。电源接线正确，仪表会将输入类型显示两秒钟。now, if the input signal is connected, it will display value of input in pv window, power delivered at present, in o/p window and setpoint in sv display along with appropriate mode led.现在，如果输入信号已经连接，仪

41、表将会在pv窗口显示输入值，电源值在o/p窗口显示，设定值在sv窗口显示，其相应的指示灯也会亮。2.2 key board 键盘there are five keys for operation of the instrument. for understanding the operation first let us see the operation of keys.仪表的操作由5个键进行。为了了解操作过程先对五个键进行介绍。set- this key is used to select desired parameter in verify, program or configurat

42、ion modes. on first press of this key, it will enter appropriate mode of operation with first parameter displayed. after the last parameter the key will bring the instrument in the run mode.设置- 此键用来实现对校验模式，编程模式或者配置模式间的选择。第一次按下此键时，将会进入合适的第一个参数的操作模式。最后一次按下此键将会使仪表处于运行模式。enter- this key is used to enter

43、 the value of the selected parameter. after setting the data to proper value, if enter key is pressed, the date will be permanently stored in non-volatile memory. on pressing of enter key, the decimal point on last digit and flashing of one particular digit disappears to indicate that data is entere

44、d. now, the data change is not allowed until enter key is pressed once again. on pressing of enter key once again, one particular digit will start flashing and decimal point on last digit will glow and allow change in the data.回车键- 此键用来确认选择参数的值。当数据给定到合适值时，如果按下回车键，此数据、会在永久性存储器中永远存储下来。当按下回车键时，最后一次数字的十

45、进制和一个特殊数字的闪动不见了，表明此数据已经输入进来了。现在，不允许改动此数据，除非回车键被再次按下。当回车键被再次按下后，一个特殊数字开始闪动，最后一次数字的十进制数亮，允许对数据进行修改。digit shift- this key adds one very good feature in the product. this key will shift the flashing digit and allow change in that particular flashing digit by increment/decrement keys, so there is fast ch

46、ange in data instead of normal increment/decrement keys. e.g. for changing from 1000 to 2000, increment key needs to be pressed once after selecting thousands digit by digit shift key.数字移动键- 此键在产品中具有很好的性能。此键可以改变闪动的数字，并允许对特殊闪动的数字通过增加/减少键来改变数字，因此通过此法可以快速改变数字，而不需用到增加/减少键。举例来说，要把1000该成2000，需要通过数字移动键移动到千

47、位数字，按一次增加键就对此数进行了修改。increment- this key will increment the selected parameter value by one count in program or configuration mode if the units digit is flashing. depending upon the flashing digit, parameter value can be incremented by 10 counts, 100 counts and 1000 counts up to the maximum value of

48、that particular parameter.增值键- 如果单位数字的灯闪烁，可以通过在编程模式下或者配置模式下按此键对此单位数字进行增值操作。根据闪烁的数字，参数值可以通过10进制，100进制和1000进制操作，直到达到此单位数字的最大值。decrement- this key will decrement the selected parameter value by one count in program or configuration mode if the units digit is flashing. depending upon the flashing digit,

49、 parameter value can be decremented by 10 counts, 100 counts and 1000 counts up to the minimum value of that particular parameter.减值键- 如果单位数字的灯闪烁，可以通过在编程模式下或者配置模式下对此数字进行减值操作。根据闪烁的数字，参数值可以通过10进制，100进制和1000进制操作，直到达到此数字的最小值。2.3 modes of operation 操作模式there are four modes of operation for the unit.此单元有四

50、种操作模式。1. run mode 运行模式2. verify mode 校验模式3. program mode 编程模式4. configuration mode 配置模式2.4 run mode 运行模式this is normal mode of display. from other modes of operations, display falls back to this mode if no key is pressed for 20 seconds. 显示的正常模式。如果在20秒内没有任何按键按下的话，操作模式自动会从别的模式回到此模式。in run mode there a

51、re two operation mode.运行模式下，有两种操作模式(a) auto mode 自动模式(b) manual mode 手动模式(a) auto mode: by selection auto prompt with yes in program mode, instrument will come in auto run mode. in this mode output power will be calculated according to the control parameters settings, i.e. pb h(proportional band), t

52、i(integral time), td(derivative time) and other batch parameters. in this mode pv display will show value of i/p signal, sv display will show the setpoint (local/remote) and o/p display will show the output power with 5% resolution (or valve position in case of position proportional output.) output

53、power can be seen with 1% resolution by keeping the digit shift key in pressed condition.自动模式：通过在编程模式下选择auto命令，然后点击yes，仪表就进入自动运行模式。在这种模式中，输出功率可以通过设置的控制参数进行计算，也就是pb h (比例带宽)，ti（积分时间），td(微分时间)和其它的批参数。在这种模式下，pv将会显示输入信号的值，sv将会显示给定值（本地/远端），o/p显示带5%分辨率的输出功率（或者位置比例输出条件下的阀门位置）。输出功率可以通过按下digit shift按键来设定1%分辨

54、率。manual mode: by selection auto prompt with no in program mode instrument will come in manual run mode. in this mode pid action will be bypassed and user can set the value of output power with 1% resolution by increment/decrement keys. for the indiction of manual mode man led will glow. in this mode pv display will show value of i/p signal, sv display
