OT DMX 6CH/12CH
Description
Description
Purpose, function and application
The LED dimmer controls high-power LED fixtures by a DMX signal using linear current dimming. It is designed for use with both high-power 1W and 3W LED fixtures.
The two versions 6CH and 12CH provide control over 6 or 12 individual channels,
which allows control of 2 or 4 highpower RGB triplets, respectively.
The dimmers can be interconnected to control large installations by DMX signal.
Within a DMX network, connected highpower LED fixtures can be controlled by a
central DMX controller (e.g. OSRAM EASY DMX SO).
The dimmer is designed for installation on DIN rail in switch cabinets.
Design
The dimmer is made up of the following components:
• Power In connection (A)
• DMX signal input/output (B)
• LCD screen (C)
• Function keys (D)
• LED outputs 1-4 (E)

Installation
Installation
Mounting the control unit
• Follow the safety instructions.
• The dimmer is designed for installation on DIN rail in switch cabinets.
• The dimmer must be oriented with the power-in terminal block and DMX data connectors towards the top to permit proper heat dissipation.
• Allow for proper distance of unit enclosure and wiring terminals for easy access,
hardware configuration and maintenance.
• When installed in an enclosure utilizing 45 mm cutouts, the front panel LCD of the
dimmer stays visible while the connections are concealed.
Connecting the power supply
CAUTION!
Destruction of the dimmer through incorrect mounting!
•
Maintain correct polarity.
The Power In connections are made using a screw terminal block (4 pins, pitch 5 mm).
•Cable type and length limitations: see appendix. .
Use at least 15 AWG (1.5 mm2) for mains connection.
•
Connect all 4 terminals of the captive screw terminal.
•Select the correct power supply unit (PSU):.
The PSU must be selected keeping in mind the maximum number of serial LEDs
per channel in the application, output cable type/length, and the power rating
needed to drive the LEDs at the desired current. See the following table:

Installation
If the PSU voltage is within normal range, the message PSU OK will be displayed on
the LCD screen. Otherwise, the message PSU FAIL will be displayed and the dimmer
will not operate.
Connecting LED fixtures
LED-wiring connections are made using pluggable terminals blocks (8 pins, pitch 3.5
mm).
Pin 1
Pin 8
• Cable type and length limitations: see appendix and PSU specific limitations.
• NTC = connection for NTC sensor. If the NTC sensor is not connected, Fixture
Thermal Protection (TP) will be disabled for that output.
TP - Fixture Thermal Protection
This feature allows the unit to receive feedback about the temperature of the connected fixture. If the environment temperature causes the fixture to overheat (max. allowed
LED fixture temperature is 75 °C), the unit will lower the level of the current passing
through the fixture until the temperature of the fixture is stabilized within the allowed
limitations. If the environment temperature declines, the unit will raise the level of the
current passing through the fixture.
Note: .
The changes of current will not affect the color of the light, but only its intensity. The
light intensity depends very much on the temperature of the LED. For example, if
an LED driven at 700 mA reaches a high temperature, its light output may decline
by half. So, if you lower the current passing through this LED, you will in fact get the
same light intensity while the temperature of the LED will be able to stabilize.
The dimmer has been calibrated using the following NTC sensor:
Thinking Electronics Industrial - TSM2A103F3802RZ
LED Wiring Test
This unit has a unique algorithm for the detection of load type and wrong LED connections. It can detect, if there is a short circuit between the LED’s (+) and (-) lines, or
mixed connection with a neighboring channel inside the terminal plug.
If the unit detects incorrect wiring on one of the outputs, that group of channels will
not be operational until the problem is fixed. If during normal operation some of the
LEDs are reconnected, the LED-wiring test will be initiated on that group to which the
disconnected channel belongs.
That way, LEDs can be hot-plugged into the system. However, connecting/disconnectIV 2010
7
OT DMX 6CH/12CH
Installation
ing LEDs under power is not recommended. It is recommended to make all connections first and then to turn on the power.
Autoload Detection
Each channel of the dimmer is capable of auto-detecting the LED load type connected
to it, and selecting the appropriate operating mode to control that load.
DRTP – Driver Thermal Protection
The dimmer has an internal temperature sensor allowing it to monitor the temperature
of the internal power circuitry. If, by any reason, the external environment temperature
exceeds the permitted limit, the unit will not permit the internal circuitry to overheat
by reducing the output power. By doing so, it avoids driver malfunction caused by
overheating, while still driving the LEDs even under worst conditions and preserving
the lifetime of the dimmer.

CAUTION!
Destruction of the dimmer and other devices through incorrect mounting!
•
If onboard 16 VDC power output is not used, make sure that this line is
insulated from any other pins!
•
Before connecting any DMX controller, refer to the installation guide of the
controller manufacturer.
The dimmer has an active DMX signal level repeater eliminating the need for a DMX
splitter/repeater when daisy-chaining dimmers together.
Note: .
The onboard 16 VDC can be used to supply power to a DMX controller from the DMX
