1 PURPOSE
S19-P is microprocessor controller for multi-spot 12V/24V LED lighting, intended for LED lighting of
staircases (and other passageways), with a separate control of each lamp. The device turns on the
consecutive LED lamps, and turns them off after a specified time. In the case of dimmable lamps, the
turning on and off happens gradually and smoothly. The controller can also provide gentle backlight
lighting as well as react to motion and dusk.
S19-P is equipped with:
 built-in configurator capable of setting 18 parameters, e.g. brightness; timing, speed, and
smoothness of turning on/off; warning when the lights are about to turn off; and many more, which
enables the users to set the device up according to their needs;
 integrated dusk switch (IDS) which disables the controller during daylight, with a light sensor that can
be installed both indoors and outdoors.
2 DESCRIPTION
2.1 Terminals
The controller’s terminals are depicted below.

S19-P User manual v5.0.6
© APACHETA Smart Systems str. 3/15
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).

2.4 Controller’s operation
The default state of the controller is the standby state when no inputs are active. In this state dimmable
lamps may be either off or on with gentle backlight; non-dimmable lamps are off. The controller is
awaiting a signal either at the DIS port (which will disable the controller and turn all the lights off) or
from any of the UP /DN inputs (which will start the lighting sequence).
2.4.1 Turning lamps on
The ‘turning-on’ phase consists of turning on consecutive lamps:
 from the first to the last, if the signal came from the UP input;
 from the last to the first, if the signal came from the DN input;
If another signal appears at the other input while the lamps are being turned on, the sequence will also
start from the other side.
If applicable, the Master lamp is turned on first, either before or at the same time as the first lamp in the
sequence. The smoothness of the turning on of the lamps can be set within a broad scope by setting the
Smoothness parameter: from sharp to very smooth turning on.
2.4.2 Lights on
When the lights are on, they remain on for a time predefined by the On time parameter. The time
extends when a new signal appears at any of the inputs.
2.4.3 Warning
When the time determined by the On time parameter passes, either the lights turn off (if the Number of
warnings parameter is set to 0) or the controller enters the warning phase (if Number of warnings is
greater than 0). The warning phase informs the user that the lights are about to turn off. The phase
consists of a number of ‘warning–waiting’ cycles consisting of the warning and awaiting the user’s
reaction. The warning can be either a short dimming of all lights (a ‘blink’), alternate dimming of the
even and odd lamps (a ‘flicker’) or a dimming of one or two lamps moving back and forth (pendulum
effect).
2.4.4 Turning lamps off
Turning off the lamps is defined as dimming the lights from the full brightness to the backlight level
brightness.
The ‘turning-off’ phase is reversed with respect to the turning-on phase: the lamps are turned off either
as they were turned on or in the reverse order (depending on the setting of the Off direction
parameter). The Master lamp (if set) is turned off last. The smoothness of the turning off is the same as
in the case of turning on, and set with the Smoothness parameter.

3 CONFIGURATION MANUAL
3.1 Introduction
The controller is configured with the built-in Configurator shown below.
The Configurator consists of the RESET button, three configurational buttons (SET, ‘+’, and ‘–’), and two
signalling LEDs, RED and GREEN. The SET button increments the number of the parameter being set or
exits the configuration procedure. The ‘+’ and ‘–’ buttons change the value of the parameter being set.
3.2 Configuration
To begin the configuration, follow the steps 3.2.1–3.2.3 below.
3.2.1 Get access to Configurator
Open the controller casing (by removing the front cover).
3.2.2 Restart the controller
Restart the controller by pressing the RESET button shortly (both signalling diodes, RED and GREEN, will
turn on for about 3 sec.).
3.2.3 Put controller into configuration mode
Immediately after the RESET button is released (while the diodes are still on), put the controller into the
configuration mode by pressing and holding the SET button until both signalling diodes start blinking
quickly (please be patient; it may take about 4 seconds); then release the SET button.
3.3 Setting configuration parameters
The configuration parameters are stored in the non-volatile memory (also after the device is switched
off). The controller is shipped with the parameters preset to default values (see Table 1).
The parameters can be set in accordance with Table 1.

S19-P User manual v5.0.6
smartLEDs
str. 6/15 © APACHETA Smart Systems
The configuration is done in a loop of 19 steps, setting one parameter per step in all the first 18 steps
except the final one. The final step allows to either restart the configuration from step 1 or to finish the
configuration. If the latter case, three options are given: (1) to save the new configuration, (2) to discard
the new configuration, or (3) to restore the factory settings.
At each step the Configurator displays, through the signalling diodes, the step number and the present
value of the parameter being set. The current value is communicated through a repeating series of
flashes of the GREEN diode, in accordance with Table 1. At the same time, the step number is
communicated by the number of flashes of the RED diode. To illustrate: a repeating single flash of the
RED diode means the parameter being set is the Number of Lamps (parameter no. 1), while 16
consecutive flashes in a series of the GREEN diode mean the current setting is ‘16 lamps.’ To change the
value of the parameter, use the ‘–’ and ‘+’ buttons (selecting the preceding or the next value from Table
1, respectively). Having set the value of the parameter (or when we want to leave its value unchanged),
we move to the next step by pushing the SET button briefly (under 2 seconds).
Reaching the final (19th) step in the loop is signalled by the RED diode giving off a steady light. There are
then two possibilities:
 To return to the beginning of the configuration loop, i.e. the first step, in order to repeat all the steps
and correct the settings, press the SET button briefly (under 2 seconds).
 Choose the desired value of the Decision? parameter with the ‘–’ and ‘+’ buttons, then press and hold
the SET button until both diodes switch off (>4s). Selecting the value SAVE will result in saving the
new configuration in the non-volatile memory of the controller. Selecting the value QUIT will result in
discarding the new configuration and restoring the previous configuration. Selecting the value
RESTORE will bring back the factory defaults.
CAUTION! Pressing the SET button briefly (under 2 seconds) will always advance the configuration
process to the next step.
CAUTION! Pressing and holding (for at least 4 seconds) the SET button (at every step except Decision?),
pressing the RESET button, or cutting off the power supply will cause the configuration process
to exit without saving the new parameters.
CAUTION! The built-in Configurator is capable of setting only the parameters shown in table 1.
CAUTION! Pressing ‘+’ when the maximum value is displayed moves the selection to the first value; and
pressing ‘–’ when the first value is displayed moves the selection to the maximum value.
CAUTION! If no button is pressed for about 30 minutes, the controller will quit the configuration mode.
CAUTION! Exiting the configuration with saving the new settings is possible only in the last step of the
sequence (Decision?), with the value set to SAVE.
3.4 Parameters set by Configurator
CAUTION! Changing the parameters indicated as ‘[advanced]’ substantially affects the operation of the
controller, and it is recommended to change these with caution.
3.4.1 Number of lamps
The number of all the LED lamps (including the Master lamp).

smartLEDs
S19-P User manual v5.0.6
© APACHETA Smart Systems str. 7/15
3.4.2 Master lamp
Allows to decide whether the last lamp is to be used as a master lamp; if the Master lamp is dimmable;
and if the Master lamp should be turned on one step before or together with the start of the lighting
sequence.
3.4.3 Number of warnings
The number of the ‘warning-waiting’ cycles; ‘0’ means no warnings.
3.4.4 Warning type
The style the warning is displayed.
3.4.5 Step type
The pace of the turning on and off of the consecutive lamps in the sequence.
3.4.6 Off direction
The order of turning off the consecutive lamps (the same as the turning on or the opposite).
3.4.7 Smoothness
The smoothness of the dimming/brightening of the lamps. This parameter determines the visual effect
of the dimming/brightening: low values of smoothness make the process energetic, while high values
make it smooth and gentle. There are seven values to choose from. In the case of non-dimmable lamps
the parameter must be set to 0; then there is no backlight lighting and the turning on and off proceeds
in a one-by-one switching fashion.
3.4.8 Brigthness
The brightness of the LED lamps.
CAUTION! While this parameter is being set, lamps L1 and L2 are lit with intensities corresponding to the
values of the Brightness and Backlight lighting parameters, respectively.
3.4.9 Backlight lighting
The brightness of the backlight lighting of the LED lamps during stand-by, expressed as the percentage
of the brightness set by the Brightness parameter.
CAUTION! While this parameter is being set, lamps L1 and L2 are lit with intensities corresponding to the
values of the Backlight lighting and Brightness parameters, respectively.
3.4.10 Master brightness
The brightness of the Master lamp.
CAUTION! While setting this parameter, the last lamp (L19) is lit with a brightness corresponding to this
parameter.
3.4.11 Master backlight
The stand-by backlight value of the Master lamp (expressed as a percentage of the Master brightness
parameter).
CAUTION! While setting this parameter, the last lamp (L19) is lit with a brightness corresponding to this
parameter.

3.4.12 Turning-on time
The time elapsed between the start of the first and the last lamp turning on.
3.4.13 On time
Determines how long the lamps remain on.
3.4.14 Warning time
The duration of a single warning.
3.4.15 Waiting time
Determines the ‘waiting’ time of the ‘warning-waiting’ cycle, when the controller awaits the user’s
reaction after a warning.
3.4.16 Turning-off time
The time elapsed between the start of the first and the last lamp turning off.
3.4.17 Active level [advanced]
The level (ZERO or ONE) defined as the active state at the controller inputs.
CAUTION! An input left floating has the value ONE. Setting the active level to ONE while an input is left
floating will result in a permanent active state.
3.4.18 2. DIS input [advanced]
Determines what is done with the active state at the DIS input. The possible parameters are: BLOCK,
UNBLOCK, TOGGLE, and S1, S2, …, S10. Selecting one of the values S1–S10 activates the built-in dusk
switch. The values from S1 (darkest) to S10 (brightest) determine the external light threshold of the dusk
sensor above which the switch blocks the controller.
CAUTION! Setting the parameter to one of S1, …, S10 with the sensor disconnected will result in the
controller not being blocked during daylight.
CAUTION! For the built-in dusk switch to work correctly, it is necessary to connect the enclosed sensor to
the DIS terminal.
CAUTION! Setting the parameter to TOGGLE allows for controlling the DIS input manually with a
pushbutton. With this setting, the controller by default starts in the active state when the
power supply is turned on.
CAUTION! The default settings of the parameters Active level and DIS input are appropriate when the
DIS port is left floating.
3.4.19 Decision?
This is the final step in the configuration process. Pressing the SET button briefly (< 2 s) restarts the
configuration process. Pressing it longer (> 4 s) exits the configurator. Choosing the SAVE option and
pressing the SET button long exits the configurator with the new configuration saved. Selecting the QUIT
option and then pressing the SET button long results in abandoning the configuration and restoring the
prior settings. Similarly for the RESTORE option: the configuration process will be halted and the factory
settings brought back.
CAUTION! To confirm the selected option (SAVE, QUIT, or RESTORE), press the SET button and hold for at
least 4 s until both signalling diodes turn off.

5 Installation instructions
The S19-P controller is a versatile device with numerous possible applications. Figure 3 depicts an
example of the most common installation.
CAUTION! Installing the controller requires technical knowledge and experience and should be carried out
by a qualified person. Connection of the power supply to the mains may only be done by a
qualified electrician.
CAUTION! All installation proceedings should be carried out with the power supply disconnected. The
voltage may only be turned on once it has been ensured all connections are correct.
CAUTION! A particular caution is advised when connecting the control inputs (UP, DN, DIS). These are
potential-free inputs and no voltage should be applied to them as it may result in burning of
the controller. Please ensure that any control device (e.g. motion sensors, including those
powered with 12V) do not apply any voltage onto these inputs.
CAUTION! We advise particular caution also when connecting the controller’s outputs. Before connecting
the output circuits (LED lamps) please ensure there are no short circuits. A short circuit (or
overload) at any of the outputs may result in burning of the controller.
The installation should follow this order:
1 Connect all LED lamps / LED strips and the power supply to the controller. For now, do not connect
anything to the controller inputs (UP, DN, DIS).
2 Check if all connections are correct and faultless: if carried out in accordance with the installation
diagram, if there are no short nor open circuits, if the polarity is set correctly, etc.
3 Insulate the connections.
4 Turn the power on. All LED lamps/strips should light up fully and after about 3s dim to the backlight
value (2% brightness).
5 Connect the OUT output of the lower DELTA sensor to the UP input. Remove the sensor cover.
Detection of a person by the DELTA sensor is signalled by the lighting of the green LED on the front
of the sensor and should cause smooth switching on of consecutive lamps from L1 to L19, and after
about 30 seconds from the end of the detection by the sensor, the lights should smoothly dim (to
the backlight level).

6 Repeat the operation from p. 5 for the DOWN sensor.
7 The next step is connecting the light probe, switch or timer to the DIS input. The probe, switch and
timer have 2 output terminals: one should be connected to GND and the other one to the DIS input
of the stair controller, in accordance with the assembly diagram. In case of light probe, in order to
activate the internal dusk switch, it is necessary to change the DIS input parameter to one of the
values from S1 (darkest) to S10 (brightest). Depending on the brightness detected the IDS should
switch the controller to active (if it’s dark) or blocked (if it’s bright) state with certain delay.
8 In the last step, if necessary, configure other controller parameters, especially Number of lamps.
Remember to make any manipulations and changes in the installation with the power off. Even a short-
term occurrence of voltage on the wrong outlet of the controller can permanently damage the
controller, and such damage is not covered by the warranty. Turn the power on only when you are sure
that everything is connected properly.
5.1 EXAMPLE DIAGRAM. Typical staircase installation of S19-P, with a common power
supply for the controller, sensors and lamps; with an optional Master lamp;
controlled by staircase sensors DELTA; with the built-in dusk sensor; and with the
option to light the lamps permanently.
Assumptions:
o 19 groups of LED staircase lamps
o optional Master lamp (L19 and L18, if not used as ordinary lamps) as the ceiling/wall light or handrail
backlight (e.g. LED strip)
o common power supply of the controller, DELTA sensors and LED lamps (typically 12 VDC)
o automatic turning on the lights by DELTA sensors
o option: permanent steady lighting with additional switches
o blocking the controller during daylight with a built-in dusk switch.
