4-CHANNEL DIMMER

This module is designed for smooth adjustment of brightness of lighting devices (non reactive load). The dimmer type is MOSFET with trailing edge dimming.Like all Larnitech devices, this dimmer controller is automatically detected and configured when it is added to the system. A logical unit within makes it possible for the unit to perform scripts from Larnitech’s large and constantly updated database and to operate on distributed logic, ensuring the reliability of its operation. Advanced LED light settings allow a more precise setup, while soft start mode prolongs lamp life. In addition to featuring protection in a range of parameters.

Features

• R/C load type supported (4 x 500 W)
• Works with halogen /LED lights
• Advanced LED light settings
• Soft start mode
• Overload protection
• Overheating protection
• Short-circuit protection
• Plug and play (automatically detected and configured by the system)
• In-built logical unit
• Regular system updates

CAUTION! All work related to the installation, connection, setting up, service and support must be carried out by qualified personnel with sufficient skills and experience in working with electrical equipment. To avoid the risk of fire, electric shock, damage to the system and/or personal injury, the system installation and assembly must be performed in accordance with the instructions listed below:

• all connectivity work must be carried out with the power turned OFF;
• use appropriate tools and personal protection against electric shock;
• do not use damaged cables, wires and connectors;
• avoid folding the cables and wires;
• do not apply excessive force to the wires by kinking or pressing them too hard: the inner conductors of the cables and wires may get stripped or damaged;
• do not use the power socket with poor contacts to connect;
• do not exceed the load limit parameters specified in the manual;
• the supply conductors wire section is subject to the specifications for current density limit, insulation type and wire material. Light section can result in cable overheating and fire.

When the power is on, NEVER:

• connect/disconnect the connectors;
• open modules and sensors.

Indication of module operation

Indicator	Status	Description
Power		Power
		Power not available
Activity		Data communication
		Data communication not available
Error		No errors
		Overheating
		No connection to AC.
		The data has not been transferred via the CAN bus for at least 5 minutes.
		No power on the lamp.
	No power on the DALI bus or over current (more then 180 mA) on DALI bus. If over current is at both bus blinking twice in half a second.

Module installation and connection procedure

1. Install the module in the switchboard on the DIN rail and fix it with the special latch on the module base.
2. Connect the CAN connector.
3. Connect the X1, X2 connectors.
4. Configure the module using LT setup.
5. Apply power to the load.
6. Check all equipment for proper operation.

Module shut-off and deinstallation procedure

1. Disconnect the power from the load.
2. Disconnect the connectors X1, X2.
3. Disconnect the CAN connector.
4. Remove the module from the DIN rail, releasing the latch at the bottom of the module base.

HW settings

Name	Type, range	SUBID	Default	Description
def	integer 0-250	1-4	100	The default brightness level in case of a power reset (1..250). Example: def=250
min	integer 0-100	1-4	0	Minimum dimming level, example: min=10
max	integer 0-100	1-4	100	Maximum dimming level, example max=95
start	integer 0-100	1-4	0	The Start function is used for lamps that lack the minimal voltage to get turned on. If the set value is lower than the start value, the lamp is turned on at the start value and them the light is dimmed down to the set level. Example: start=60
force	integer 0-100	1-4	10	Time duration of the starting value (measured in milliseconds). Example: force=20
runtime	integer 0-60000	1-4	1000	Runtime is the speed of changing the brightness from 'min' to 'max' (measured in milliseconds). Example: runtime=1000
protect	integer 0;1	1-4	1	Overload Protect. 0(off); 1 (on), example: protect=0
