2 Safety notes

2.1 Correct use
Safety in operation is only guaranteed if the actuator
is used correctly.
The actuators NR 24 and NR 230 are used for the
motorized actuation of 3- and 4-way mixing valves.
The actuators can be activated via any commercial
control system with a three point output.
If the actuator rotates clockwise, the flow temperature
increases until the limit stop of the actuator is reached
(supply open, bypass closed). The flow temperature
drops if the actuator rotates anticlockwise until the
opposite limit stop is reached (supply closed, bypass
open).
Any use of the valve outside of the above applications
will be considered as non-compliant and misuse.
Claims of any kind against the manufacturer and/or
his authorised representatives due to damages caused
by incorrect use cannot be accepted.
The observance of the installation and operating
instructions is part of the compliance terms.
2.2 Possible dangers at the installation location
and during transport
The case of an external fire has not been taken into
consideration when constructing the actuator.
WARNING
Hot and cold surfaces
Risk of injury Only touch with safety gloves. The
actuator can get very hot during operation.
Small components
Risk of ingestion
components supplied with the actuator out of reach
of children.
Allergies
Health hazard Do not touch the actuator and avoid
any contact if allergies against the used materials
are known.
3 Transport, storage and
packaging
3.1 Transport inspection
Upon receipt check delivery for any damages caused
during transit.
Any damage must be reported immediately upon
receipt.
3.2 Packaging
Packaging material is to be disposed of environmen-
tally friendly.
Store and install small

4.2 Performance data
Operating current
Absorbed power
Protective system
Torque
Manual setting
Ambient temperature
Length of cable
The angle of rotation is limited to 90°. Having reached
the limit stops, the actuator is switched off electrically
and is without current. In case of a malfunction of the
control system, the actuator can be converted to
manual operation with the help of an additional rotary
knob.
