Inputs

NameDescriptionTypeRange
Online statusShows if the device is online or offline. This input is hidden by default and can be displayed via the properties of the device (“Show diagnostic inputs”).Digital0/1
CPU TemperatureDisplays the current CPU temperature of the Nano 2 Relay Tree.Analogue
Temperature switch offIf the CPU temperature reaches a critical point, the outputs of the device are switched off. This can be due to short-circuits, too high switched loads or too high an ambient temperature.Digital0/1
Current flowingIf the current flow is greater than the defined threshold, the input is activated.Digital0/1

Purpose
Specifies the purpose of the actuator.
Universal actuator: Freely usable outputs
Shading actuator: Link to an automatic blind block
Drop down selection box
Automatic travel timesAutomatically learn travel times for complete movement of the blinds (for use with shading actuator). This is not possible for motors with insufficient power (less than 50W). In this case, this option should be deactivated and the travel times entered manually for Tu and Td in the automatic blinds blockDigital0/1
Reverse outputsReverse direction of rotation if up/down has been inverted (Up connected to down, down connected to up).Digital0/1
Threshold for current detection (mA)If current greater than the specified threshold is measured, the ‘Current flow’ input is activated. The current from relay 1 and relay 2 is added. This property is only available when “Shading Actuator” is selected as the purpose.Analogue100 … 5000

Programming

After the Nano 2 Relay Tree has been inserted into the peripherals, run Auto Configuration. A new automatic blinds block is inserted automatically and the device is assigned. If the Nano 2 Relay Tree is used as a universal actuator, the two outputs can be configured as required.
