Application

Direct coupled actuators for direct link to LonWorks network. Actuators are easily installed by direct shaft mounting on air dampers in ventilation and air conditioning systems. Actuator can be controlled by any compatible LON system.

For proportional modulation of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications.

The actuator is mounted directly to a damper shaft up to 1.05” in diameter by means of its universal clamp. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.

Operation

The actuator is not provided with and does not require any limit switches, but is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement.

The GMX24-LON series provides 95° of rotation and a visual indicator indicates position of the actuator. When reaching the damper or actuator end position, the actuator automatically stops. The gears can be manually disengaged with a button on the actuator cover.

The GMX24-LON actuators use a brushless DC motor, which is controlled by an actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode.

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.

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_temp

SNVT_switch

SNVT_flow

SNVT_flow_p

SNVT_abs_humid

SNVT_enthalpy

SNVT_ppm

SNVT_rpm

SNVT_lux

SNVT_press_p

SNVT_smo_obscur
