4. Setup and Installation
Follow these steps for proper installation of the Omron Z-15GW2-B7-K snap switch:
- Power Disconnection: Ensure all power to the circuit is disconnected before beginning installation. Verify with a voltage tester.
- Mounting: The switch is designed for snap-in mounting. Secure the switch using the mounting dimensions of 1.03 inches centers. Ensure the mounting surface is stable and free from excessive vibration.
- Wiring:
- Identify the screw terminals. The SPDT contact form typically includes Common (C), Normally Open (NO), and Normally Closed (NC) terminals. Refer to the wiring diagram on the switch body if available.
- Connect the appropriate wires to the screw terminals. Ensure connections are tight and secure to prevent loose contacts and overheating.
- Use wire gauges suitable for the 15A current rating.
- Actuator Alignment: Position the hinge roller lever actuator so that it can be reliably engaged by the target mechanism. Ensure the mechanism provides sufficient over travel (0.157 In.) and does not exceed the maximum pretravel (0.157 In.) for consistent operation.
- Environmental Considerations: Install the switch in an environment within its specified operating temperature range (-25°C to 80°C) and where its IP65 rating is sufficient for protection against dust and water ingress.
- Testing: After installation, carefully restore power and test the switch's operation to confirm correct functionality and wiring.
5. Operating Instructions
The Omron Z-15GW2-B7-K snap switch operates based on the physical displacement of its hinge roller lever actuator. When the actuator is depressed, the internal contacts switch state.
- Actuation: The switch requires an operating force of approximately 3.5 oz. to actuate. The hinge roller lever is designed to be engaged by a moving part of machinery or equipment.
- Contact Function (SPDT):
- In its normal (unactuated) state, the Common (C) terminal is connected to the Normally Closed (NC) terminal.
- When the hinge roller lever is depressed, the Common (C) terminal switches connection to the Normally Open (NO) terminal.
- The switch maintains this state as long as the actuator is depressed. Upon release, the contacts return to their normal state.
- Operation Mode: The switch functions in an OFF-NONE-ON mode, meaning it has a stable OFF state, a transient ON state when actuated, and returns to OFF when released.
6. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your Omron snap switch.
- Inspection: Periodically inspect the switch for any signs of physical damage, wear on the hinge roller lever, or loose wiring connections.
- Cleaning: Keep the switch free from dust, dirt, and debris. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or abrasive materials.
- Actuator Check: Verify that the mechanism actuating the hinge roller lever is operating smoothly and consistently, without excessive force or misalignment.
- Environmental Protection: Ensure that the environmental conditions remain within the specified IP65 rating. If the housing is damaged, the protection level may be compromised.
- Power Disconnection: Always disconnect power before performing any maintenance or inspection.
7. Troubleshooting
If you encounter issues with your Omron Z-15GW2-B7-K snap switch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
