Modulating, Non-Spring Return, Linear, 24 V, Multi-Function Technology®

Linear force min. 101 lbf for control of damper surfaces up to 32 sq.
ft.

Application

For proportional modulation of dampers in HVAC systems. Actuator sizing
should be done in accordance with the damper manufacturer’s specifications.
The default parameters for 2 to 10 VDC applications of the …MFT actuator are
assigned during manufacturing. If necessary, custom versions of the actuators
can be ordered. The parameters can be changed by two means: pre-set and
custom configurations from Belimo or on-site configurations using the Belimo

PC-Tool software.

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

The actuator provides 4” [100 mm] of linear stroke. The stroke of the gear rack
can be adjusted on both sides in increments of 0.8” [20 mm] by means of the
mechanical end stops.

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 actuators use a sensorless brushless DC motor, which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls
the 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.

Wiring Diagrams

Actuators with appliance cables are numbered.

A

Provide overload protection and disconnect as required.

Actuators may also be powered by 24 VDC.

Only connect common to negative (-) leg of control circuits.

A 500 Ω resistor (ZG-R01) converts the 4 to 20 mA control signal to 2
to 10 VDC.

Control signal may be pulsed from either the Hot (Source) or Common
(Sink) 24 VAC line.

For triac sink the Common connection from the actuator must be
connected to the Hot connection of the controller. Position feedback
cannot be used with a triac sink controller; the actuator internal
common reference is not compatible.

Actuators may be connected in parallel if not mechanically linked. Power
consumption and input impedance must be observed.

IN4004 or IN4007 diode. (IN4007 supplied, Belimo part number

40155).
