, Non-Spring Return, 24 V
Node object #0
The node object contains the object status and object request functions.
nviRequest SNVT_obj_request
Input variable for requesting the status of a particular object in the node.
nvoStatus SNVT_obj_status
Output variable that outputs the current status of a particular object in the node.
nvoFileDirectory SNVT_address
Output variable that shows information in the address range of the Neuron chip.
Damper actuator object #8110
The actuator object is used to map the functions of the MP actuators to the
LONWORKS® network.
nviRelStpt SNVT_lev_percent
The nominal position is assigned to the actuator via this input variable. This variable is
normally linked to the output variable of an HVAC controller.
nviActuateState SNVT_switch
A preset position is assigned to the actuator via this input variable. Note on priority:
The last variable that was active, either nviActuatorState or nviRelStpt, has priority.
nviManOvrd SNVT_hvac_overid
These input variables can be used to manually override the actuator into a particular
position.
nvoActualValue SNVT_lev_percent
This output variable shows the current actual position of the actuator and can be used
for control circuit feedback or for displaying positions.
nvoAbsAngle
SNVT_angle_deg
This output variable shows the current angle of rotation of the actuator
or the valve and can be used to display the position or for service purposes.
nvoAbsAirFlow SNVT_flow
This output variable is inactive with the SR24ALON-5 rotary actuator and shows a
constant value of 65535 (this variable is only active in conjunction with LON-capable
VAV controllers).
Open loop sensor object #1
A sensor can be connected to the rotary actuator. A passive resistance sensor (e.g.
Ni1000), an active sensor (output 0 ... 32 V) or a switch (on/off) can be connected. The
open loop sensor object transfers the measured sensor values to the LONWORKS®
network.
nvoSensorValue SNVT_xxx
This output variable shows the current sensor value. Depending on the connected
sensor, the output variable can be configured via the sensor plug-in and specifically
adapted to the system.
The SNVT_... can be configured as:
SNVT_temp_p
SNVT_lev_percent
SNVT_lux
SNVT_temp
SNVT_abs_humid
SNVT_press_p
SNVT_switch
SNVT_enthalpy
SNVT_smo_obscur
SNVT_flow
SNVT_ppm
SNVT_power
SNVT_flow_p
SNVT_rpm
SNVT_elec_kwh

K
K
The LON-capable damper actuator is certified by LonMARK
®
. The actuator functions
are supplied with the LonWorks
®
network as standardized network variables
according to LonMARK
®
. The Node Object #0, the Damper Actuator Object #8110
and the Open Loop SensorObject #1 are implemented in the actuator.
