For transformer design (voltage drop), each thermal actuator must be counted at the full start
load, since the Triac outputs can be freely controlled.
The heating sequence and cooling sequence are not normally active at the same time
(Exception: Downdraft compensation).
The sum total of the base load, bus power, field supply, and Triacs will not exceed 62 VA @
24VAC and 80 VA @32VAC.
See Section Power data.
DC 0…10 V output
The DC 0…10 V output supply max. 1 mA.
Digital inputs
Digital inputs are not suitable for operating lighting or blinds. Use the KNK PL-Link pushbutton.
Differential pressure input
On board differential pressure input for 0… 500 Pa (0…2 in WC)
Mounting
The DXR2.x10… is mounted directly on a damper shaft.
The mounting bracket must be installed with enough clearance for device rotation.
See the installation instruction for detailed information.
Installation
Applies to devices with supply output (24 VAC or mains voltage) such as triac output or output to
supply a field device.
WARNING
No internal line protection for supply lines to external consumers
Risk of fire and injury due to short-circuits
● Adapt the line diameters as per local regulations to the rated value of the installed fuse.
Operation
The outputs have no electricity when power fails.
USB communications failure can be caused by weak or incorrect grounding at DXR 24 V power
termination. (The power terminal labeled ⏊ must be connected to earth ground.)
Disposal
The device is considered an electronics device for disposal in terms of European
Directive 2012/19/EU and may not be disposed of as domestic garbage.
● Dispose of the device through channels provided for this purpose.
● Comply with all local and currently applicable laws and regulations.
