DIMMER SETTINGS

MYCR-250 is supplied set for leading edge dimming and can be set to trailing edge dimming.
Selection of an appropriate setting is dependent on the type of load to be connected – see the table below. Contact the place of purchase for your luminaire/light if you are not sure what type of load is to be set.

LOAD SETTING OUTPUT
Halogen lamps and bulbs Trailing edge 25-250W /220-240V W RL
Electronic transformers Trailing edge 20-250W / 220-240V
Dimmable LED and low-energy bulbs Trailing edge 3-120W / 220-240V
Conventional transformers Leading edge 40-250W / 220-240V

SWITCH BETWEEN LEADING EDGE AND TRAILING EDGE DIMMING

  1. Switch on the connected charge using the ON/OFF button on the receiver.
  2. Press and hold down the ON/OFF button on the receiver for 10 seconds.
  3. The LED indicator on the receiver flashes in series of 4.
  4. Briefly press the ON/OFF button to toggle between leading edge and trailing edge dimming.
  5. The LED indicator on the receiver flashes quickly and the connected (light) flashes twice and then dims to the set minimum level in order to confirm the new setting.

The LED indicator shows the set dimming method every time MYCR250 is switched on or off using the ON/OFF button.
LED flashes once = Leading edge dimming
LED flashes twice = Trailing edge dimming

SETTING THE MINIMUM DIMMER LEVEL

  1. Switch on the connected charge using the ON/OFF button on the receiver.
  2. Press and hold down the ON/OFF button on the receiver for 3 seconds.
  3. The LED indicator on the receiver flashes in series of 2.
  4. Use a programmed remote control to adjust the minimum dimmer level. ON increases the level by one step, OFF decreases the level by one step (4 steps in total).
  5. Briefly press the ON/OFF button to save the minimum dimmer level set.
  6. The LED indicator on the receiver flashes quickly and the connected (light) flashes twice and then dims to the set minimum level in order to confirm the new setting.

Safety and information

Indoor range: up to 30 m (optimal conditions). The range is strongly dependent on local conditions, such as the presence of metals. For example, the thin metal coating in Low-emissivity (Low-E) glass has a negative impact on the range of radio signals.
There may be restrictions on the use of this device outside the EU. If applicable, check whether this device complies with local directives.

Maximum load: Never connect lights or equipment that exceed the maximum load of the receiver, as it can result in defects, a short circuit or fire.

Life-support: Never use Nexa products for life-support systems or other applications in which equipment malfunctions can have life-threatening consequences.

Interference: All wireless devices may be subject to interference, which could affect performance. The minimum distance between 2 receivers should be at least 50 cm.

Repairing: Do not attempt to repair this product. There are no user-serviceable parts inside.

Water-resistance: This product is not water-resistant. Keep it dry. Moisture will corrode the inner electronics and can result in a short circuit, defects and shock hazard.

Cleaning: Use a dry cloth to clean this product. Do not use harsh chemicals, cleaning solvents, or strong detergents.

Environment: Do not expose the product to excessive heat or cold, as it can damage or shorten the life of electronic circuit boards.
