- The dimmer has a number of 'error indication' LEDs (see fig. 1), which indicate defects such as
over voltage, over current and overheating.
The 3 'error indication' LEDs are located at the top left of the cover, with symbols: I, U and T. The
load LED is located at the top left, with symbol
Meaning of the LEDs:
1 LED lights steadily.
2 LED I lights steadily.
3 LED 'I' blinks.
This may occur if the dimmer is overloaded or in case of switch-on peaks.
4 LED 'U' lights steadily.
5 LED 'U' blinks.
Over voltage may have several causes:
- 230V mains power failure, either temporary or not;
- Magnetic transformer with excessive induction due, for instance, to insufficient load (min. load of
magnetic transformers 80%);
- Magnetic transformer with changed load (defective lamps not replaced in due time);
- Dimmer not set to correct mode, e.g. dimming of inductive loads in reversed phase control instead
of phase control mode
6 LED 'T' lights steadily.
The temperature of the cooling surface exceeds 105°C.
7 LED's 'I' and 'U' blink.
8 LEDs 'I', 'U' and 'T' light steadily.
9 LEDs 'I', 'U' and 'T' blink.
- Once the defect has been repaired, the dimmer can be restarted by briefly pressing the 'select'
key or performing an operation.
6. WARNINGS WITH RESPECT TO OPERATION
- This appliance is not suitable for the control of motors.
- When using a ferromagnetic transformer, check whether it is suitable for use in combination with
an electronic control.
