Application

For fail-safe, proportional control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifi cations. A feedback signal is provided for position indication.

Default/Configuration

Default parameters for 2 to 10 VDC applications of the NKQ..-MFT actuator are assigned during manufacturing. If required, custom versions of the actuator can be ordered. The parameters noted in the Technical Data table are variable. These parameters can be changed by three means:

  • Pre-set or custom confi gurations from Belimo.
  • Confi gurations set by the customer using the most current MFT PC tool software application.
  • Handheld ZTH-GEN.

Operation

The NKQ..24-MFT actuator provides 95° of rotation and a visual indicator shows the position of the actuator. When reaching the damper or actuator end position the actuator automatically stops. The gear can be manually disengaged by pressing the black button located on the actuator cover. The NKQ..24-MFT actuators use a brushless DC motor, which is controlled by an Application Specifi c Integrated Circuit (ASIC). The ASIC monitors and controls the actuators rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in a holding mode. The actuator is electronically protected against overload. The anti-rotation strap supplied with the actuator will prevent lateral movement. Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions.

Fail-Safe Indication

LED status indicator lights sequence: Yellow off / Green on: operation ok, no faults Yellow off / Green blinking: fail-safe mechanism is active Yellow on / Green off: fault is detected Yellow off / Green off: not in operation / capacitors charging Yellow on / Green on: adaption running Yellow blinking / Green on: communication with programming tool
