LON-Actuators

Product catalog summary

Overview: This document provides technical specifications and configuration details for a damper actuator, including network variables, configuration properties, and technical data.

Network Variables: The document outlines several network variables such as nviRelStpt (input variable for controllers), nviActuatState (software override function), and nvoActualValue (reflects current position). It also includes emergency override variables like nviEmergOvrd for incidents such as fire and smoke.

Configuration Properties: Key configuration properties include nciMinSendTime and nciMaxSendTime which define the minimum and maximum periods for output variable updates. Other properties like nciDirection and nciActuatType specify rotation direction and actuator type.

Technical Data: The actuator features a Neuron 3150 processor, 32kB Flash Eprom memory, and a brushless D.C. motor. It operates on 24VAC with a power consumption ranging from 1.5W to 5W. The rotating angle is adjustable up to 90°, with torque options of 15Nm and 20Nm.

Operational Details: The actuator is factory-adjusted to a 90° rotating angle. For dampers without final stops, the rotating angle limit is set by nciMinSetpoint and nciMaxSetpoint. For dampers with final stops, a position run can be initiated using nciInit. Safety positions are automatically selected if network communication is interrupted.

Additional Information: The document includes contact information for GRUNER AG and notes that technical changes are reserved.
