• Control voltage 230 V and/or 8-230 V UC.
• Low standby loss of only 0.7 Watt.
• ESL optimization and multifunctionality.
• Silent operation due to bistable relay, no coil power loss or heating.
• Automatic detection of circuit type (3-wire or 4-wire).
• Precise time setting from 1 to 30 minutes with a minute scale.

2. Safety Warnings

WARNING: This device must be installed only by qualified professionals. Improper installation can lead to electric shock, fire, or damage to the device.

• Always disconnect power at the main circuit breaker before installation, maintenance, or troubleshooting.
• Ensure all wiring complies with local and national electrical codes.
• Do not exceed the specified voltage and current ratings of the device.
• Protect the device from moisture and extreme temperatures.

3. Setup and Installation

The Eltako TLZ12-8PLUS is designed for modular installation on a DIN-EN 60715 TH35 mounting rail. Its compact size (1 module unit, 18 mm wide, 58 mm deep) allows for easy integration into standard electrical distribution boards.

3.1 Wiring Diagrams

The timer supports both 3-wire and 4-wire circuits. The device automatically detects the circuit type. Double terminals are provided for push-button and lamp connections, allowing flexibility in wiring from either top and bottom or only bottom.

It includes a smaller view of the timer module, followed by connection examples for 3-wire and 4-wire circuits. The diagrams illustrate how to connect the timer for staircase lighting applications, showing connections for phase (L), neutral (N), and the switched load. Detailed German text describes functions such as electronic operation with switch-off warning, DIN rail mounting, contact type, and specific features like permanent light and button-controlled permanent light.

3.2 Connection Terminals

Refer to the product image for terminal identification:

This image displays the Eltako TLZ12-8PLUS staircase light timer. It is a compact blue module designed for DIN rail mounting. Visible features include connection terminals labeled +C1, -C2, L, N, and 3, 4, along with adjustment dials for time settings and function selection. The model name 'TLZ12-8plus' and electrical ratings '230V~/C1-C2 8-230V~' are clearly marked.

• L: Phase input (230V AC)
• N: Neutral input
• +C1 / -C2: Control voltage input (8-230V UC)
• 3 / 4: Switched output for the load (e.g., light fixture)

3.3 Installation Steps

1. Ensure power is disconnected at the main circuit breaker.
2. Mount the TLZ12-8PLUS onto the DIN rail in your electrical distribution board.
3. Connect the phase (L) and neutral (N) wires to the corresponding terminals.
4. Connect the push-button(s) to the control voltage input (+C1 / -C2) as per the wiring diagram for your specific setup (3-wire or 4-wire).
5. Connect the load (e.g., staircase light) to the switched output terminals (3 / 4).
6. Double-check all connections for security and correctness.
7. Restore power. After installation, wait for a short automatic synchronization before the switched load is connected to the mains.

4. Operating Instructions

The TLZ12-8PLUS offers various functions controlled by its rotary switches.

4.1 Time Setting

Use the central rotary dial to set the desired lighting duration. The precise time setting ranges from 1 to 30 minutes, indicated by a minute scale.

4.2 Function Selection

The larger rotary switch allows selection of different operating modes:

• Standard Timer Function (TLZ): The lighting switches off automatically after the set time. If a power failure occurs during the timing, the lighting will switch on again once power is restored if the timer had not yet expired.
• Switch-off Warning: When activated, the lighting will flicker approximately 30 seconds before the set time expires. This flickering occurs 3 times at decreasing intervals, signaling that the light is about to turn off.
• Push-button Permanent Light: This function allows the light to be switched on permanently by pressing the push-button for longer than 1 second. The permanent light automatically switches off after 60 minutes or can be manually switched off by pressing the button for longer than 2 seconds.
• ESL Optimization: If energy-saving lamps (ESL) are used, set the switch-off warning and push-button permanent light functions to the right ESL side of the rotary switch for optimal performance.

If both push-button permanent light and switch-off warning are activated, the switch-off warning will occur after the permanent light is switched off.

5. Maintenance

The Eltako TLZ12-8PLUS is a maintenance-free device. No user-serviceable parts are inside. For cleaning, ensure the power is disconnected and wipe the exterior with a dry, soft cloth. Do not use abrasive cleaners or solvents.

6. Troubleshooting

• Light does not turn on: Check power supply, wiring connections, and the functionality of the push-button and lamp. Ensure the timer is correctly set.
• Light stays on permanently: Check if the permanent light function is accidentally activated. Verify wiring for any short circuits or incorrect connections.
• Timer does not switch off: Ensure the time setting is correct. If using ESL lamps, verify the ESL optimization setting.
• Flickering or erratic behavior: Ensure the correct lamp type is used and that the timer's capacity is not exceeded. For ESL/LED lamps, ensure the ESL optimization is correctly set.

If issues persist after checking these points, consult a qualified electrician.
