PSR service switch serves as an emergency street lighting control. In the event of the clock failure,
it may take over its tasks, thus allowing service engineers to identify, diagnose and remove the defect.
The system may be mounted in any control cabinet. Its major advantage is a possibility of connecting
two sensors at a time, which increases failure-free operation of the device. If one sensor is defective or
in the event of an act of vandalism resulting in the damage to the sensor (e.g. removed or covered as
a result of painting), the second sensor takes over all functions and controls the device independently.
The device detects if measuring elements have been connected and if they work properly. In case of
any irregularities or lack of connection of light-sensitive elements, a relevant LED light in the front
panel will activate. If light-sensitive elements have not been connected, ST control output in FOTO
mode is inactive. The device has regular boundary values of lighting activation (15 lx) and deactivation
(25 lx). Two information outputs Q1 and Q2 inform about switch knob location and defective operation
of sensors or their absence.

4. READING WORK STATUS VIA LED SIGNALS
PSR service switch adopts LED lights to inform the user about current working mode, sensor efficiency
and presence of sensors.
LED light colors:
1. AUTO plain green
2. ON plain green
3. OFF plain green
4. FOTO two-colored green/red
Activity of modes and any failures are signaled by means of the following: Green LED lights (items 1,
2, 3 and 4) and red LED light located in the item 4, which has been presented in greater detail below:
8PSR
Table 1. Switch status signaling through front panel lights.
AUTO ON OFF FOTO
AUTO constant green x x flashing red * or constant red **
ON x flashing green x flashing red * or constant red **
OFF x x flashing green flashing red * or constant red **
FOTO x x x flashing green, flashing red *
or constant red **
* If one light-sensitive element is missing in the system, LED light in FOTO mode flashes every 1 second,
if no light-sensitive element is connected to the switch, the light flashes twice within a second.
** If a microcontroller checks the presence of sensors in the system, that is in other words their physical
connection, but fails to measure the change of luminous flux on the surface of sensors within a day, it will
notify the user of this by activating the red LED light in FOTO mode, which will glow constantly.

WORK MODE
9PSR
DESCRIPTION OF DEVICE WORK MODES:
1. AUTO: A default basic work mode, efficient system composed of properly working clock, contactor
and switch, is AUTO mode – which means that the clock is the most important element and it is
the clock that determines when to activate the main contactor along with the group of luminaires.
In this position green LED light glows constantly. In addition, in AUTO mode LED light in FOTO
mode may glow as well, which may suggest a failure of sensors or lack of connection to the unit.
2. ON: In ON mode – PSR is the main element. It serves to supply phase (L) to the main contactor.
What is more, in ON mode a LED light in FOTO mode may also glow, which may suggest a failure
of sensors or lack of connection to the unit.
3. OFF: In OFF mode – in main contactor coil there is no potential, which suggests that it is
deactivated. Additionally, in ON mode a LED light in FOTO mode may glow, which may suggest
a failure of sensors or lack of connection to the unit.
4. FOTO: In FOTO mode – PSR is the main element, and to be more specific – sensor circuit with
a microcontroller. Depending on the lighting intensity, the main contactor is activated at a proper
time. The system may base its operation solely on one sensor, but it is not advisable. In FOTO
mode a time-lag has been applied in order to prevent against accidental additional illumination
(a car going by) or covering the surface of sensors. Such a time-lag lasts 60 seconds.
10 PSR
The device is equipped with a buzzer, that is an element which generates an acoustic wave. It coope-
rates with the limit switch located in the cabinet. The sound signaling is active in ON, OFF and FOTO
modes and informs that the user has left the device in a different position than default AUTO and closed
cabinet door. Once PSR has been closed, it makes a sound for 60 seconds and then falls quiet auto-
matically. If the cabinet door is opened again before the period of 60 seconds has passed, the device
stops making a sound. The limit switch must be connected to the S input. Polarization in this connection
does not matter.
5. SOUND SIGNALING
A 60-second sound informs the user that the switch
is active and the cabinet door has been closed.
