NOTE:
When using EFB24-MFT-S N4, and EFX24-MFT-S N4(H) actuators, only use accessories
listed on this page.
For actuator wiring information and diagrams, refer to Belimo Wiring Guide.
Typical Specification
Spring return control damper actuators shall be direct coupled type which require no
crank arm and linkage and be capable of direct mounting to a jackshaft up to a 1.05”
diameter. The actuator must provide proportional damper control in response to a 2 to
10 VDC or, with the addition of a 500
Ω
resistor, a 4 to 20 mA control input from an
electronic controller or positioner. The actuators must be designed so that they may be
used for either clockwise or counterclockwise fail-safe operation. Actuators shall use
a brushless DC motor controlled by a microprocessor and be protected from overload
at all angles of rotation. Run time shall be constant, and independent of torque. A 2 to
10 VDC feedback signal shall be provided for position feedback. Actuators with
auxiliary switches must be constructed to meet the requirements for Double
Insulation so an electrical ground is not required to meet agency listings. Actuators
shall be cULus Approved and have a 5 year warranty, and be manufactured under ISO
9001 International Quality Control Standards. Actuators shall be as manufactured by
Belimo.
Wiring Diagrams
1
Provide overload protection and disconnect as required.
2
CAUTION
Equipment Damage!
Actuators may be connected in parallel if not mechanically mounted to the same
shaft. Power consumption and input impedance must be observed.
3
Actuators may also be powered by 24 VDC.
4
Position feedback cannot be used with Triac sink controller.
The actuator internal common reference is not compatible.
5
Control signal may be pulsed from either the Hot (source) or the Common
(sink) 24 VAC line.
8
Contact closures A & B also can be triacs.
A & B should both be closed for triac source and open for triac sink.
9
For triac sink the common connection from the actuator must be connected
to the hot connection of the controller.
Meets UL requirements without the need of an electrical ground
connection.
The ZG-R01 500
Ω
resistor may be used.
WARNING
Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it may be
necessary to work with live electrical components. Have a qualifi ed licensed electrician
or other individual who has been properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical safety precautions when exposed to
live electrical components could result in death or serious injury.
