Functions
Type Step dimming
15.51…0400
Operating mode 1 (with memory):
the previous light level is memorized.
Long control pulse: The light level is progressively raised
or lowered through a maximum of 10 incremental steps.
Short control pulse: Alternately switches between On
and Off.
When switching On, the light level assumes the value set
during the previous On state.
Operating mode 2 (without memory): on switch off, the light level is not memorized.
Long control pulse: The light level is progressively raised
or lowered through a maximum of 10 incremental steps.
Short control pulse: Alternately switches On or Off
between the maximum light level and the off state.

Operating mode 3 (with memory): the previous light level is memorized.
Long control pulse: The light level is progressively raised
or lowered.
Short control pulse: Alternately switches between On
and Off.
When switching On, the light level assumes the value set
during the previous On state.
Operating mode 4 (without memory): on switch off, the light level is not memorized.
Long control pulse: The light level is progressively raised
or Lowered.
Short control pulse: Alternately switches On or Off
between the maximum light level and the off state.
Operating mode setup
Type 15.51 Type 15.91
On 15.51 operating mode 1 or 3 (with memory) is preset, but it is possible to
change it using the following sequence:
a) remove the supply voltage;
b) press the control button;
c) apply the supply to the relay, keeping the button closed for 3 second;
d) on button release, the light will flash twice to indicate the selection of operating
mode 2 or 4, or flash once for operating mode 1 or 3.
Repeating the above steps will alternately change between operating modes.
On 15.91 operating mode 4 (without memory) is preset, but it is
possible to change it using the following sequence:
a) remove the supply voltage;
b) press the control button;
c) apply the supply to the relay, keeping the button closed for 3 second;
d) on button release, the light will flash twice to indicate the selection of
operating mode 3, or flash once for operating mode 4.
Repeating the above steps will alternately change between operating
modes.
Type 15.21.8.230.0200
The dimmer is pre-set for “Trailing edge” dimming, but it is possible to
set “Leading edge” using the following sequence:
a) disconnect the power supply ;
b) press and hold down a push-button ;
c) restore power while holding down the button until the lamp produces.
one or two ashes and, at this point, release the button. If 2 ashes are emitted the new set method will be Leading Edge,
if only one ash is emitted the method will be Trailing Edge
