auto-tune key.controls are in place within the programming.)cp|keyThe functions of this key change according to how long it is pressed.Pressing this key for less than one second,lets you scroll through the parameters within the mode.Pressing this key for one second or more,brings up the the menu display and allows you to select which mode you need to adjust.In key operations from here on,press the key indicates that you must press the key for less than one second.For details on parameter switching and menu display items,refer to Parameters and Menus in Section 1.西 keyEach press of the|key increments or advances the values or settings on the No.2 display,while each press of the 3 key decrements or returns the values or settings on the No.2 display.Some keys have more than one use.For example,when the 丨丨 key is held down simultaneously with the display key,or a key is held down continuously.For details,see Selecting Modes in Section 1.Also,refer to examples(using various key combinations)in Sections 3 and 4.3Input and OutputSection 1-21-2 Input and Output1-2-1 InputThe E5CK supports four different types of inputs.Temperature Input/Voltage Input/Current InputOnly one of these inputs can be selected and connected to the controller:Temperature input Voltage input Current inputNote:The above figure shows temperature input connected to the controller.The following input sensors can be connected for temperature input:Thermocouple:K,J,T,E,L,U,N,R,S,B,W,PLII Platinum resistance thermometer:JPtlOO,Pt 100The following currents can be connected for current input:4 to 20 mA,0 to 20 mAThe following voltages can be connected for voltage input:1 to 5 VDC,Oto 5 VDC,0 to 10 VDC4Input and OutputSection 1-2Event InputWhen using event input,add on the Input Unit E53-CKB.Select from the following five event inputs:Multi-SP Run/Stop Auto/Manual1-2-2 OutputThe E5CK supports these four outputs.Control output 1 Control output 2 Auxiliary output 1 Transfer outputWhen using control outputs 1 and 2,set the output unit(sold separately).Eight output units are available to suit the output circuit configuration.When using transfer output,add on the Transfer Output Option Board E53-CKF.Note:The output functions of the E5CK do not operate for five seconds after the E5CK is turned ON.Output AssignmentsThe E5CK supports the following eight output functions.Control output(heat)Control output(cool)Alarms 1 to 3 LBA Error 1(input error)Error 2(A/D converter error)Assign these output functions to control outputs 1 and 2 and auxiliary output 1.Two guidelines are:Only control output(heat),control output(cool),alarms 1 to 3,and LBA can be assigned to control outputs 1 and 2.Only alarms 1 to 3,LBA,and errors 1 and 2 can be assigned to auxiliary output 1.In the example given in Section 1-2(previous page),control output(heat)is assigned to control output 1;alarm 1 is assigned to control output 2;and,alarm 2 is assigned to auxiliary output 1.In this configuration,heating control output is connected to control output 1;and,alarm output is connected to control output 2 and auxiliary output 1.In a heating and cooling control,assign control output(cool)to either control output 1 or control output 2.Parameters and MenusSection 1-3Transfer OutputThe E5CK supports the following five transfer outputs.Set point Set point during SP ramp Process value Heating side manipulated variable Cooling side manipulated variableThese transfer outputs can be output after being scaled.Reverse scaling is also possible because setting an upper limit value smaller than the lower limit value is allowed.1-3 Parameters and Menus1-3-1 Parameter TypesE5CK parameters are distributed between the following nine modes.Protect mode Manual mode Level 0 mode Level 1 mode Level 2 mode Setup mode Expansion mode Option mode Calibration modeThe settings of parameters in each of seven modes(excluding the protect mode and manual mode)can be checked and modified by selection on the menu display.Protect ModeLimits use of the Menu and Keys.The protect function prevents unwanted modification of parameters and can also be used to prevent switching between the auto and manual operation.Manual ModeSets the controller to manual operation mode.You can only manually adjust the manipulated variable(MV)in this mode.Level 0 ModeFor normal operation.Change:the set point during operation,and start or stop Controller operation;and,(only in this mode)monitor the process value,ramp SP,and manipulated variable.Level 1 ModeFor adjusting primary control parameters.Execute:AT(auto-tuning);set alarm values;set the control period;and,set PID parameters.Level 2 ModeFor adjusting secondary control parameters.Set parameters for:limiting the manipulated variable and set point;switch6Parameters and MenusSection 1-3between the remote and local modes;set the loop break alarm(LBA)alarm hysteresis,and the digital filter value of inputs.Setup ModeFor setting the basic specifications.Set parameters for:input type,scaling,output assignments and direct/reverse operation.Expansion ModeFor setting expanded functions.Set:ST(self-tuning),SP setting limiter.Select:advanced PID or ON/OFF control.Specify the standby sequence resetting method.Initialize parameters;and,set the time for automatic return to the monitoring display.Option ModeFor setting option functions.Set:the communications conditions;transfer:output and event input parameters to match the type of Option Board installed in the Controller.This mode will be accessible_only when an option board is installed in the controller.Calibration ModeFor calibrating inputs and transfer output.Calibrate the selected input type.Transfer output can be calibrated only when the Transfer Output Option Board E53-CKF has been installed in the Controller.Menu DisplayTo select the menu display in any of the above modes(excluding the protect mode and manual mode),press the 花目 key for 1 second minimum.If you select the desired mode using the|为 or 13 keys and press the key,the top parameter in the specified mode is displayed.1线 2MWhen you have selected the menu display,the previous mode is selected.For example,if you selected the menu display while in the level 0 mode,the No.2 display changes to L u-0 as shown on the left.Protected modes cannot be selected.Also,the menu display does not appear when modes are protected up to the level 1 mode.Level 0 to 2 ModesIf you select Lu-D Lu-/or Lu-?in the menu display,the level 0,level 1 and level 2 modes,respectively,are selected.These modes are selected with control still continuing.Setup Mode Expansion Mode Option Mode Calibration modeIf you select SEE E6PE or f L b in the me
