When you turn-on the LED dimmer, the output is set at 100% and the minimum of dimming is at 1%.
To access the device menu, click the push button 15 times in 5 seconds-time.
When the Load flashes, you are in “MENU 1”.
•MENU’ 1 – MINIMUM VALUE OF DIMMING
Every single click make it changing the minimum value of dimming
There are six levels of minimum: 0,1%, 1%, 5%, 10%, 20%, 30% and 100%
After setting the minimum value of dimming press long to confirm.
A double flashing confirms the storage and you can go to “MENU’2”
Note: if you set the minimum level to 100%, once the setting is confirmed, the device automatically exits the MENU.
•MENU’ 2 – POWER-ON RAMP (FADE IN)
Every single click make it changing the power-on ramp
There are five levels of power-on ramp (FADE IN): instantaneous, 1 second, 2 seconds, 3 seconds, 6 seconds.
After setting the FADE IN press a long to confirm.
Three flashes confirm the storage and you can go to “MENU’3”
•MENU’ 3 – POWER-OFF RAMP (FADE OUT)
Every single click make it changing the power-off ramp
There are five levels of power-off ramp (FADE OUT): instantaneous, 1 second, 2 seconds, 3 seconds, 6 seconds.
After setting the FADE OUT press long to confirm.
Three quick flashes confirm the storage and you go out from the “DEVICE MENU’”
When you are out of the Menu’, the Lamp which is connected to the LED Dimmer turns on at the minimum level of dimming previously set.

➢SYNC INSTALLATION
SYNC FUNCTION WITH SINGLE POWER SUPPLY
It is possible to connect multiple device of the family DLM-1CV among them in mode Master Slave.
Connect the local command desired to the device used as Master. Connect master “TX” signal to the “RX” entrances of slave.
Example of Master Slave.
SYNC FUNCTION WITH ONE POWER SUPPLY FOR DIMMER
In the case multiple power supplies are used to power “master” dimmer and “slave” dimmers, connect all the “COM” inputs of the LedDimmer to each
other.
NOTE FOR MASTER / SLAVE INSTALLATION
1) Using one power supply every single dimmer, first power on the Master unit and after that give power to the Slave.
2) When doing maintenance on the installation take care of shutting down power to the Slave units first and than to the Master.
3) When power to the Master unit is missing, the Slave set up automatically to the default ex-factory settings (power on 100%) or to the settings
previously saved.

TECHNICAL NOTE
Installation:
• Installation and maintenance must be performed only by qualified personnel in compliance with current regulations.
• The product must be installed inside an electrical panel protected against overvoltages.
• The product must be installed in a vertical or horizontal position with the cover label upwards or vertically; Other positions are not permitted. It is not
permitted to bottom-up position (with the cover label down).
• Keep separated the circuits at 230V (LV) and the circuits not SELV from circuits to low voltage (SELV) and from any connection with this product. It is
absolutely forbidden to connect, for any reason whatsoever, directly or indirectly, the 230V mains voltage to the bus or to other parts of the circuit.
Power Supply:
• For the power supply use only a SELV power supplies with limited current, short circuit protection and the power must be dimensioned correctly.
In case of using power supply with ground terminals, all points of the protective earth (PE = Protection Earth) must be connected to a valid and certified
protection earth.
• The connection cables between the power source "low voltage" and the product must be dimensioned correctly and they should be isolated from every
wiring or parts at voltage not SELV. Use double insulated cables.
• Dimension the power supply for the load connected to the device. If the power supply is oversized compared with the maximum absorbed current, insert
a protection against over-current between the power supply and the device.
Command:
• The length of the connection cables between the local commands (N.O. Push button, 0-10 V, 1-10 V, Potentiometer or other) and the product must be
less than 10m; the cables must be dimensioned correctly and they should be isolated from every wiring or parts at voltage not SELV. Use double insulated
shielded and twisted cables.
• The length and type of the connection cables at the BUS SYNC must be less than 3m and they should be isolated from every wiring or parts at voltage
not SELV. It is suggested to use double insulated shielded and twisted cables.
• All the product and the control signal connect at the bus and at the local command (N.O. Push Button, 0-10V, 1-10V, Potentiometer or other) must be
SELV (the devices connected must be SELV or supply a SELV signal)
Outputs:
• The length of the connection cables between the product and the LED module must be less than 10m; the cables must be dimensioned correctly and
they should be isolated from every wiring or parts at voltage not SELV. It is suggested to use double insulated shielded and twisted cables.
