- To activate the circuit, press or toggle the control mechanism to the 'ON' position. The internal contact will close, allowing current to flow.
- To deactivate the circuit, press or toggle the control mechanism to the 'OFF' position. The internal contact will open, interrupting the current flow.
The switch provides a clear tactile feedback when operated manually.
6. Maintenance
The Eltako S12-100-230V electromechanical switch requires minimal maintenance. Regular inspection can help ensure its longevity and safe operation.
- Cleaning: Periodically clean the exterior of the switch with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
- Inspection: Annually inspect the wiring connections for any signs of loosening or corrosion. Tighten connections if necessary, ensuring power is off.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature wear or failure.
7. Troubleshooting
If the Eltako S12-100-230V switch is not functioning as expected, consider the following troubleshooting steps:
- No Power: Check the circuit breaker or fuse for the circuit. Ensure power is supplied to the switch.
- Incorrect Wiring: Verify that all wires are correctly connected to the appropriate terminals according to the wiring diagram. Ensure connections are secure.
- Overload: Ensure the connected load does not exceed the maximum current (10A) or wattage (6W) rating of the switch. An overload can cause the switch to fail or trip protective devices.
- Manual Operation Check: Confirm that the manual control mechanism is fully engaged in the desired position.
- Device Damage: If there are visible signs of damage to the switch, discontinue use immediately and replace the device.
If the issue persists after performing these checks, contact a qualified electrician or Eltako customer support for further assistance.
