You will no longer be able to operate the ZENif you forget your password.• The password setting range is 0000 to 9999 (4 decimal digits).• You will no longer be able to perform the following operations ifthe password is not input correctly.Edit ladder programsMonitor ladder programsChange or delete the passwordSet the input filterSet the node address• When any of these functions is selected from the menu, thePassword Input Screen will be displayed.
If the password is inputcorrectly, the display will move to the next screen for the selectedfunction. However, if the password is input incorrectly, the nextscreen will not be displayed.76Protecting Programs4-1-1Section 4-1Setting a PasswordPARAMETERSET CLOCKLANGUAGEOTHERSelectOther.▲SelectPassword.PASSWORDCONTRASTBACKLIGHTINPUT FILTER▼PASSWORDPress the OK Button to change to a flashingcursor and enable a password to be set.0000PASSWORD1234Set the password.Use the Left and Right Buttons to move tothe digit to be changed.Use the Up/Down Buttons to input a numeralbetween 0 and 9.PASSWORDSET?OK/ESC1234PASSWORDCONTRASTBACKLIGHTINPUT▼Press the OK Button.

Input filters can be set separatelyfor the CPU Unit and each Expansion I/O Unit.Operation (Example: DC Input Circuits)Input detectionvoltageInput15 ms 15 msInput circuitdetection(No input filter)Input circuitdetection(With input filter)7850 ms15 ms50 ms15 ms 15 ms50 ms15 ms50 msStabilizing Input OperationsSection 4-2PASSWORDCONTRASTBACKLIGHTINPUT FILTER▼SelectOther/Inputfilter.Press the OK Button to display the Input Filter Settings Menu.INNEREXP1EXP2EXP3//CPU Unit inputExpansion I/O Unit input(Displayed only when ExpansionUnits are connected.)INPUT FILTERINNEROFFUse the Up and Down Buttons to select fromthe menu the Unit for which the input filter isto be set.Press the OK Button twice to change to aflashing cursor and enable input filter settings to be made.OFFINPUT FILTERINNER/Use the Up/Down Buttons to switch betweenON and OFF.ONPress the OK Button to confirm the setting.Press the OK Button again to complete thesetting.Note 1.The filter timers outlined in the following table are set for eachinput type when the input filter function is set.Input specificationsAC inputDC input2.Inputfilter notusedInputfilter used100 VAC50 ms240 VAC100 ms70 ms120 ms15 ms50 msThe input filter settings are read when the ZEN starts operation.79Changing Backlight Automatic Cutout Time4-3Section 4-3Changing Backlight Automatic Cutout TimeThe LCD backlight automatically turns ON when button operations areperformed.
It then turns OFF automatically 2 minutes after button operations stop. The default backlight cutout setting of 2 minutes can bechanged to 10 or 30 minutes or the backlight can be set to remain ONcontinuously.Button operationOperationstarts.....OperationstopsDisplay function (when L1or L3 is set)OFF ® ON.....ON ® OFFBacklight statusLit.DD0SelectOther/Backlight.Remains lit.Remains lit.Turns OFF.PASSWORDCONTRASTBACKLIGHTINPUT FILTER▼BACKLIGHT2min2min/Cutout timeDD0BACKLIGHTPress the OK Button to display the currentbacklight cutout setting.Press the OK Button again to change to aflashing cursor and enable backlight cutouttime settings to be made.Use the Up and Down Buttons to set the cutout time.10minON (Continuously ON)30 min10 min2 minPress the OK Button to confirm the setting.Press the OK Button again to complete thesetting.Note The backlight cutout time is used not only to determine if andwhen the backlight turns OFF after button operations havestopped.
