Product Usage Instructions

Timing Range:
The timing range for the ZK-KTD2 Trigger Cycle Timer Delay Controller is determined by the delay time settings.

Parameter Description:

OP: Delay time for turn On
CL: Delay time for turn OFF
LOP: Number of cycles. Range is 1-999 times. ‘—-‘ means unlimited loop.
CLL: Minimum value of random delay time range. The set range is 0.0~99.9 seconds. This CLL parameter is only used for P15 work mode.
CLH: Maximum value of random delay time range. The set range is 0.0~99.9 seconds. This CLH parameter is only used for P15 work mode. CLH is greater than CLL.

Power-ON Delay Mode:
In the Power-ON Delay Mode, the ZK-KTD2 Trigger Cycle Timer Delay Controller will start the delay after power on, without the need for any other trigger signal.

P00: Power ON and output keep OFF and start delay time CL. Then turn ON output after delay time CL. Example: Power ON -> OFF -> Delay CL -> ON.
P01: Power ON and output turn ON and start delay time OP. Then turn OFF output after delay time OP. Example: Power ON -> ON -> Delay OP -> OFF.
P02: Power ON and output turn ON and start delay time OP. Then turn OFF output after delay time OP. Keep OFF for delay time CL. Then turn ON output after delay time CL. And then loops the above action. The number of cycles (LOP) can be set. Output will keep OFF after the cycle. Example: Power ON -> ON -> Delay OP -> OFF -> Delay CL -> cycles -> OFF.
P03: Power ON and output turn OFF and start delay time CL. Then turn ON output after delay time CL. Keep ON for delay time OP. Then turn OFF output after delay time OP. And then loops the above action. The number of cycles (LOP) can be set. Output will keep ON after the cycle. Example: Power ON -> OFF -> Delay CL -> ON -> Delay OP -> cycles -> ON.

Pulse Signal Trigger Mode:
In the Pulse Signal Trigger Mode, the ZK-KTD2 Trigger Cycle Timer Delay Controller will start the delay after receiving an input trigger signal.

P04: Input trigger signal and output turn ON and start delay time OP. Then turn OFF output after delay time OP. Triggering again during the delay is invalid. Example: Trigger -> ON -> Delay OP -> OFF.

Random Delay Mode:

P15: Input trigger signal and output keep OFF and start delay time. The delay time between CLL and CLH. Then turn ON output after delay time CLL~CLH. This mode also can set PWM duty cycle from 20%,25%,30%,35% to 100% in 600Hz by parameter SP. (The delay time is a random value between CLL and CLH. Their setting range is 0.0~99.9second and CLH is more than CLL.) E.g. Trigger->OFF->Delay->ON.

Set steps

Confirm the working mode before start to set mode and parameters.
Keep press SET Button about 2second enter to select work mode.
Press UP and Down button to switch work mode P00~P015.
Press SET button to set parameter value for selected work mode such as P03 work mode.
The first set parameter OP will flashing about 2second and display parameter value.
Press STOP button to move the decimal point and set delay time range.
Press UP and Down button to set OP parameter value.
Press SET button to set the second parameter value CL. Then set time range and parameter value as the same method.
Press SET button to set the third parameter value LOP. Then set parameter as the same method.

It is relay switch output, so it can not output voltage. The load also needs to be connected to the load voltage.
It will display ‘000’ if stop work. It shows the decimal point when working.
