1WARNINGS AND SAFETY PRECAUTIONS
PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY BEFORE TURNING THE LED LIGHT SOURCE SL 3500 ON!
GENERAL ELECTRICAL SAFETY GUIDELINES:
•Perform a routine check of the devices and their wiring.
•Replace worn or damaged cords immediately.
•Use appropriate electrical extension cords/power bars and do not overload them.
•Place the devices on a flat and firm surface. Keep them away from wet floors and counters.
•Avoid touching the device, socket outlet or switch if your hands are wet.
•The LED Light Source should by always used with the original power supply (control unit) supplied by the manufacturer.
•Do not perform any alterations to the electrical part of the devices or their components.
•Never cover the power supply (control unit) or the light panel! Low ventilation can cause an irreversible damage to the device.
WARNING:
The LED Light Source SL 3500 is considered Class 1M* LED Product. LED radiation may be harmful to eye. Avoid direct and strongly
reflected exposure. It is recommended to use protective glasses.
*Class 1M: Laser and LED equipment that is safe under reasonable conditions of operation for use with the naked eye. Looking
directly into the source of radiation by employing optics within the beam such as magnifying glass, telescope or microscope can
be potentially hazardous.

2GENERAL DESCRIPTION
The SL 3500 range of LED lights from Photon Systems Instruments are arrays of high-performance light emitting diodes that can operate
under multiple regimes such as flash, continuous light and harmonically modulated light. They can also function work user-defined
protocols. Different versions of the device are available with LEDs spanning the spectrum from blue to far-red.
The SL 3500 panels can be used as stand-alone units, or they can be integrated into cultivation areas and to provide lighting for growth
rooms. The panels may also be integrated with other PSI instruments such as FluorCams, Photobioreactors or FytoScopes.
Basic control of the SL 3500 panels is by a supplied control unit. Enhanced output and modulation may be controlled by PSI’s Light
Controller LC 100, which provides precise regulation of light mode, intensity and timing. Optionally, PSI’s Light Studio Software, allows
computer control of the LED panels. User-defined protocols may be designed and implemented via both the Light Controller and the
Light Studio Software.

2.3 OPTIONAL ACCESSORIES
2.3.1 LIGHT STUDIO 485 SW WITH LIGHT CONTROLLER LC 500
Light Studio Software is a PC solution for precise control over the light mode, intensity and timing - (microseconds to hours). It supports
light channel calibration and grouping. It can control unlimited number of logical light channels, formed from up to 254 physical light
devices. Each logical channel can be configured independently. Light modulation is fully programmable, built from user-defined segments
(continuous light and ramp). The software offers flexibility regarding the protocol composition and timing. There are just two predefined

items –constant element and ramp element. The protocol is then built from these two. A user can also add light channels to various
groups and control them as one item/with one protocol.
2.3.2 LIGHT CONTROLLER LC 100
LC 100 is a hardware, stand-alone solution for precise control
of light characteristics and day/night simulation
in SL 3500 LED Light Sources. It provides precise control over
the light mode, intensity and timing (seconds to hours) and
maintains also generation of short pulses (micro-seconds).
It can control up to 4 lights/colors in SL 3500; each light /color
can be configured and controlled independently. Light
Controller LC 100 supports light modulation according to
a predefined function (continuous, pulse, sine, triangle),
user-programmed function (optional), or daylight simulation
(optional). No PC is needed for this device operation.
2.3.3 USER-DEFINED CUSTOM PROTOCOL
Optional feature to the Light Controller LC 100: when uploaded to Light Controller, this Protocol can support up to 224 light phase
intervals, each defined by light intensity and duration.
2.3.4 DAYLIGHT PROTOCOL
Optional feature to the Light Controller LC 100: when uploaded to Light Controller, the Daylight Protocol serves for cloudy skies
simulations - several adjustable parameters. Includes also additional program for "cloud visualization" on a PC.

Step 2: Connect the Light Panel to the Power Supply
(control unit) (Fig. 11).
[1] Connect the Light Panel to the Power Supply
(control unit) using the LED PANEL connector.
[2] For the external control, connect the
communication cable of the Light Controller LC
100 or of a PC to the Power Supply –use the
LIGHT TRIGGER connector.
Step 3: Connect the mains cable to the Power Supply
(control unit) (Fig. 12).
[1] Connect the mains cable to the connector on rear
part of the Power Supply (control unit).
Step 4: Connect the device to an electrical power source (110/230V). Be sure that the device and all peripheral units are switched off!

Step 5: Switch on the device.
[1] Switch on the power switch of the Power
Supply control unit) (Fig. 13).
[2] When using your LED Light Source with the
Light Controller, first switch on the Power
Supply. Then, switch on the Light Controller
LC 100 (Fig. 14).
5DEVICE OPERATION
The device can be controlled either in the manual mode or in the external mode:
•The manual control mode allows permanent lighting that can be controlled in the intensity.
•The external control mode provides the possibility of creating sophisticated protocols for precise control of the light mode, intensity
and timing. Light can be dynamically modulated with periods ranging from microseconds to hours. The external control mode requires
either the Light Controller LC 100 or the Light Studio software in a PC.

6MANUAL CONTROL
[1] The light intensity can be set on the front panel of the Power Supply (control unit) in the range of 0 –100 %.
[2] When using a multiple channel version of the device, each channel controls a different color. Each color’s intensity can
be controlled independently.
7EXTERNAL CONTROL
[3] Connect the Light Controller or the computer with the Light Studio software to the LIGHT TRIGGER connector of the Power Supply.
[4] Enable the external light control by pushing the light trigger to REMOTE position.
More information on the external control mode is provided in the Operating Manuals of the Light Controller LC 100 or of the Light
Studio software.
