4. Mode Select Switch: The mode select switch is located on the front of the timer and is used to select the desired timer mode. The available timer modes include ON delay, instantaneous, flicker, ON delay flicker, repeat cycle, and signal off-delay.
- ON delay: The timer starts counting when the input signal is received and activates the output after the set delay time.
- Instantaneous: The output is immediately activated when the input signal is received.
- Flicker: The output turns ON and OFF alternately at a set frequency when the input signal is received.
- ON delay flicker: The output turns ON after the set delay time and then turns ON and OFF alternately at a set frequency.
- Repeat cycle: The timer activates the output for a set ON time and then deactivates it for a set OFF time.
- Signal off-delay: The output activates when the input signal is received and deactivates after the set delay time.
5. Wiring Diagram: The H3DS-ML comes with a wiring diagram that illustrates how to connect the timer to the input and output devices. It is important to refer to the wiring diagram and follow the instructions carefully to ensure proper installation.
By familiarizing yourself with these components, you will be able to effectively install and configure the Omron H3DS-ML timer for your specific application.
How to make connections
When wiring the Omron H3DS-ML timer, it is important to follow the correct procedures to ensure proper functioning. The wiring diagram provides a visual representation of how the connections should be made. Here are the steps to make the connections:
- Power supply: Connect the positive (+) terminal of the power supply to terminal 10 of the timer and the negative (-) terminal of the power supply to terminal 11 of the timer. Ensure that the power supply voltage matches the specifications of the timer.
- Control input: Connect the control input signal (e.g. a switch or sensor) to terminal 2 of the timer. This signal will be used to start or stop the timer.
- Output contacts: The timer has two output contacts, labeled ‘1a’ and ‘1b’. Connect the load (e.g. a motor or solenoid) to these contacts. The ‘1a’ contact is normally closed, meaning it is connected when the timer is not activated. The ‘1b’ contact is normally open, meaning it is disconnected when the timer is not activated.
