Applicatio
n
For proportional modulation of dampers in HVAC systems. Actuator sizing
s
hould be done in accordance with the damper manu
f
acturer’s speci
fi
cations.
The actuator is mounted directly to a damper sha
f
t up to 1.05" in diameter by
means o
f
its universal clamp
.
The default parameters for 2 to 10 VDC applications of the …MFT actuator are
assigned during manu
f
acturing. I
f
necessar
y
, custom versions o
f
the actuators
c
an be ordered. The parameters can be changed b
y
two means: pre-set and
c
ustom con
fi
gurations
f
rom Belimo or on-site con
fi
gurations using the Belimo
PC-Tool software
.
Operatio
n
The actuator is not provided with and does not require an
y
limit switches, but

.
The GMX24-MFT-T N4
p
rovides 95° of rotation and a visual indicator indicates
position o
f
the actuator. When reachin
g
the damper or actuator end position,

The
G
MX24-MFT-T N actuators use a brushless D
C
motor, which is controlled
by an Application Specifi c Integrated Circuit
(
ASIC
)
. The ASIC monitors
and controls the actuator’s rotation and provides a di
g
ital rotation sensin
g
(DRS) function to prevent damage to the actuator in a stall condition.Power
