[. . . ] Using Timers and Holding Timers X: ON-delay timer Trigger input Reset input Setting Present value 0 Timer bit Output Trigger input Timing Turns ON after set delay after the trigger input turns ON. Basic Operation Main Applications When delayed operation or a time lag is required. Stays ON while the trigger input is ON and turns OFF after a set delay after the trigger input has turned OFF. Basic Operation Trigger input Timing Output : OFF-delay timer Trigger input Reset input Setting Present value 0 Timer bit Main Applications Useful for OFF delay circuits for lights or fans Turns ON for a set period after the trigger input turns ON and regardless of how long the trigger input remains ON. Basic Operation Trigger input O: One-shot pulse timer Trigger input Reset input Setting Present value 0 Timer bit Timing Output Main Applications Useful for set operations where operation is always required during a regular period only. Repeatedly turns ON and OFF in a set cycle while the trigger input is ON. Basic Operation Trigger input Timing Output Timing Timing Timing F: Flashing pulse timer Trigger input Reset input Setting Present value 0 Timer bit Main Applications Useful for flashing emergency lights or sounding buzzers as the output for an alarm circuit. Repeatedly turns ON and OFF in a set cycle while the trigger input is ON. Independent ON- and OFF-time settings are possible. Basic Operation Trigger input Timing Timing Timing Timing (OFF-time) (ON-time) (OFF-time) (ON-time) Output W: Twin timer Trigger input Reset input ON-time OFF-time Present value 0 Timer bit Main Applications Useful for intermittent (ON/OFF) operation, such as that used for fans. 3. Using Holding Timers X: ON-delay timer Trigger input Reset input Setting Present value 0 Turns ON after set delay after the trigger input turns ON. The present value is held while the trigger input is OFF. Main Applications To continue operation after momentary power loss or power interruptions. Also can be used when delayed operation or a time lag is required. Timer bit 20 Programmable Relay ZEN V2 Units 4. Counter Operation Counter direction specification input Counter input Reset input Set value Present value 0000 Counter bit The counter bit turns ON when the counter value (present value) reaches the set value (present value set value). The counter returns to 0 and the counter bit turns OFF when the reset input turns ON. Count inputs are not accepted while the reset input is turned ON. The counter present value and counter bit (ON/OFF) are held even if the operating mode is changed or the power supply is interrupted. 5. 8-digit Counter Operation Count speed H High speed Counter direction specification input Counter input Reset input Operation The counter bit turns ON when the counter value (present value) reaches the set value (present value set value). The counter returns to 0 and the counter bit turns OFF when the reset input turns ON. Count inputs are not accepted while the reset input is turned ON. The counter present value and counter bit (ON/OFF) are held even if the operating mode is changed or the power supply is interrupted. [. . . ] · Do not remove the label from the left side of the CPU Unit if a Battery Unit is not mounted. Other · The execution of the ladder program in the ZEN is different from that for other PLCs. Refer to "Difference between ZEN Programmable Relays and PLC Ladder Program Execution" on page 33. · Abide by all local ordinances and regulations when disposing of the ZEN. · The Battery Unit (ZEN-BAT01, sold separately) contains a lithium battery.
