Overload safety switch
The user has a option with parameter 70 to set a overload safety switch threshold. If the
threshold is set (by default is set to 200W) and the power exceeds it for 5 seconds the Mini
Dimmer will turn off, the red LED will turn ON and a “Overload detected” notification w ill be sent.
To restore normal operation the user must press the switch I1 or send a control frame.
Overload protection:
Maximum Power Limit is automatically set by the device’s software which is 220 Watt. If the
maximum power is exceeded for more than 5 seconds, the dimmer will turn off until the next
power cycle and the red LED will turn ON. If this happens, check if the load matches the device
specifications and if connections are according to the diagram. To restore the dimmer to its
regular operation, please power cycle the device.
When overload occurs, an “Over - load detected” notification is sent to the gateway (hub).
Maximum Power Limit is not same as Overload safety switch (parameter no. 70).
Watchdog
To protect the Mini Dimmer against getting stuck in an undesired state, the watchdog timer is enabled.
Toggle Switch Mode:
Switch toggles (parameter 1 set to 1) the state of the light bulb between the last dimming value
and 0. If the last dimming value is 0 then the light is turned 100% ON when the switch changes
its state.
Bulb types which support dimming function:
• Traditional incandescent bulbs
• Halogen bulbs operated by 240 V AC (High Voltage Halogen)
• Low voltage halogen bulbs with electronic or conventional transformers
• Dimmable compact fluorescent bulb (CFL). If the bulb flickers, set the parameter 60
(minimum dimming value) to value 30 or up
• Dimmable LED bulbs
