5. Setup and Installation

5.1 Mounting

The ELPA 8 is designed for quick and easy installation on a standard DIN rail within an electrical distribution board. Ensure the DIN rail is securely mounted and accessible for wiring.

5.2 Wiring

Installation must be performed by a qualified electrician in accordance with local wiring regulations. The device supports a 4-wire connection. Refer to the wiring diagram printed on the device (Figure 1) for correct connections.

• L: Live input
• N: Neutral input
• 3: Push-button input (for triggering the timer)
• 4: Switched output (to the lighting circuit)

Ensure all connections are tight and secure to prevent loose contacts and potential hazards.

6. Operating Instructions

6.1 Time Setting

The desired lighting duration can be set using the blue rotary wheel on the front of the device. Rotate the wheel to align the desired time (in minutes) with the indicator mark. The scale provides an absolute time setting, typically ranging from 0.5 to 7 minutes.

6.2 Continuous Light Function

The ELPA 8 features a practical toggle switch located above the time setting dial. In the 'light bulb' position, the timer function is active, and the light will switch off after the set duration. Moving the toggle to the 'sun' position activates continuous light, bypassing the timer. The light will remain on until the toggle is returned to the 'light bulb' position to re-enable timer operation.

7. Maintenance

The Theben ELPA 8 is designed for maintenance-free operation. To ensure longevity and proper function:

• Ensure the device is kept clean and free from dust.
• Do not attempt to open or repair the unit yourself, as this may void the warranty and pose a safety risk.
• For any issues requiring internal inspection or repair, consult a qualified electrician.

8. Troubleshooting

If the stair light timer switch is not functioning as expected, consider the following:

• No Light: Check the power supply to the device and ensure all wiring connections are secure and correct according to the diagram (Figure 1). Verify that the light bulb(s) in the circuit are functional.
• Light Stays On Continuously: Check the position of the continuous light toggle switch. Ensure it is set to the timer function (light bulb icon) and not the continuous light function (sun icon).
• Incorrect Timing: Re-adjust the rotary wheel to the desired time setting. Ensure the wheel is not obstructed.
• Device Not Responding to Push-button: Ensure the push-button input (terminal 3) is correctly wired and the push-button itself is functional. Test the push-button for continuity if possible.

If problems persist after checking these points, contact a qualified electrician for further assistance.
