2.1.1
Power supply
The controller requires external power supply with regulated DC output, safety extra-low voltage (SELV)
in the range of 8–24 V DC; it should also have a minimum current load of 100 mA. The power is supplied
to the GND terminal (ground, minus) and the 12V terminal (plus).
CAUTION!
Only use power supplies marked
and with galvanic separation between the output voltage
and the mains supply.
2.1.2
Inputs
The controller has the following inputs:
UP and DN ports which control upward and downward turning on of the lamps, and
DIS port for disabling the controller, used for example for connecting the light sensor or an external
switch.
The inputs should be fed with a potential-free signal of either connection (ZERO) or non-connection
(ONE) to ground GND.
CAUTION!
The only external dusk sensors and clocks suitable for using with S19-P are those marked
and with galvanic insulation of the output voltage and the mains supply.
2.1.3
Outputs
S19-P has 19 outputs L1-L19 that control the LED lamps connected to them. Any LED lamps powered
with SELV of up to 24 V DC can be used, provided that they are supplied from a DC SELV power supply
(up to 24 V) with a galvanic insulation of the output voltage from the mains supply. The maximum
current must not exceed 2 A per single output. The outputs should be connected to the negative
terminal (cathode) of the LED lamps.
The outputs can be used either with dimmable LED lamps (smooth turning on/off, gentle backlight
lighting), as well as non-dimmable (instantaneous turning on/off, no backlight lighting).
The last two outputs (L18 and L19) can be used as the Master lamp; this lamp is turned on first and
turned off last.
2.2
Configurator
The parameters of S19-P may be set up with the integrated configurator (see Sec. 3).
2.3
Integrated dusk switch (IDS) with a light sensor
S19-P is equipped with an integrated dusk switch (IDS). The IDS disables the controller’s operation
during daylight, and is activated by connecting the light sensor to the DIS port and setting the threshold
light level by configuring the
DIS input
parameter to a value between S1 and S10. The IDS responds only
to long-term changes in light conditions, ignoring any short-term fluctuations. The light sensor may work
both outdoors and indoors, which makes it more convenient than external dusk sensors that work
properly only when exposed to natural sunlight (any artificial light sources can cause malfunction of
external dusk sensors).
