The program will not operate properly ifsuch lines are drawn.2.Always press the ESC Button and return to the Menu Screenafter creating a program.
If you do not press the ESC Buttonand return to the Menu Screen before turning OFF the power,the program and settings will be deleted.3.Do not use the same output bit address for more than one output from the program. The resulting operation may not be asexpected.I0I1[Q0[Q0Here, the final status of Q0will be controlled by I1, notby I0.49Confirming Ladder Program Operation3-4Section 3-4Confirming Ladder Program OperationAlways check the ladder program operationbefore using the ZEN.Note1.Before turning ON the power, check thatthe power supply, input circuits, and output circuits have been wired correctly.2.For systems with loads connected to theoutputs that may cause serious injury ordamage to equipment if operation is incorrect, remove the output wiring beforeperforming trial operation.3.Always ensure safety in the vicinity before turning ON the power or switchingoperating modes.Procedure for Checking OperationChecks Before Turning ON the Power1.Check that the ZEN is mounted andwired correctly.2.Check that the operation of the ZEN willnot have a negative impact on the system.
Check for any dangers.3.Turn ON the power supply to the ZEN.Switch to RUN mode while the ZEN isstopped.4.Turn each input ON and OFF and checkthat the program is operating correctly.5.Adjust any problems.Operation ChecksMethod for Checking OperationLCD-type CPUUnitsCheck the operation by the flashing input and output displays on the MainScreen.LED-type CPUUnitsConnect the ZEN Support Software and check operation using the monitorfunction.
