FAQs
What is the primary function of the Eltako TLZ 12?
The Eltako TLZ 12 is a staircase light timer that automatically switches off lights after a set period, conserving energy and ensuring lights are not left on unnecessarily.
What does 'switch-off pre-warning' mean?
It means the light will flicker approximately 30 seconds before it turns off completely, giving occupants a warning that the light is about to extinguish.
Can this timer be used for new installations?
This model is primarily designed for retrofitting existing 3-wire systems. It may not be suitable for entirely new installations unless a 3-wire circuit is specifically planned.
What is the maximum time setting?
The timer can be precisely set from 1 to 12 minutes using the integrated minute scale.
How does zero-crossing switching benefit my lamps?
Zero-crossing switching reduces electrical stress on the contacts and lamps, especially extending the lifespan of energy-saving and LED lamps by minimizing power surges.
What is the standby power consumption?
The Eltako TLZ 12 has a very low standby loss of only 0.7 watts.
How do I activate the continuous light function?
There is a separate large rotary switch specifically for activating the continuous light mode whenever needed.
Troubleshooting
Light does not turn on.
Verify that the power supply is connected correctly and that the circuit breaker is engaged. Check all wiring connections to the device and the load.
Light does not turn off automatically.
Ensure the timer is set correctly and not switched to the 'continuous light' mode. Check for any wiring errors or potential short circuits.
Switch-off pre-warning is not functioning.
Confirm that the pre-warning feature is enabled and correctly wired. Check the internal settings or consult the manual for specific activation requirements.
Device is not responding to the timer settings.
Ensure the time setting dial is securely in the desired position. Perform the initial synchronization if it's a new installation and power was cycled.
Device overheats.
Check the load connected does not exceed the maximum rated capacity (1000VA for fluorescent tubes). Ensure adequate ventilation around the unit.
