Direct Coupled Damper Actuator

Model MY6050A1001

General

Model MY6050A1001 direct coupled damper actuator is a

motorized actuator to open/close a damper. Model

MY6050A1001 provides 2-position or floating control in

response to a command from a controller. Combined with a

Model QY9010A1014 auxiliary potentiometer, Model

MY6050A1001 provides proportional control in response to a

command from a proportional controller.

Features

without power supply.

•Standard models are equipped with rotation angle

adjuster (mechanical stopper), enabling to adjust motor

operating position.

•Low power consumption allows energy conservation.

•Large torque is assured despite compact, lightweight

design.

•Simple physical structure facilitates installation on most

types of the damper shafts.

•Optional auxiliary devices offer a variety of applications.

Installation

CAUTION



•To prevent product damage, always disconnect

the power supply from the product before

performing installation.

IMPORTANT:

•

void application that keeps product operating

cycle excessively frequent.

•Meet the rotating direction of the actuator with the

damper rotating direction.

•Tighten the screws so that the actuator is securely

assembled with the damper.

•For the product installation, secure maintenance

clearance shown in Fig. 1.

Installation procedure

1) Fully close the damper shaft.

Figure 4. Damper shaft

2) Fully close the actuator Model MY6050A, and mount it

to the damper shaft. Finger-tighten the fastening nuts of

the shaft clamp to temporarily fix the actuator.

Figure 5. Temporal installation of the actuator body

3) With the gear release button pressed , manually rotate

the shaft clamp until it is in the position shown in Fig. 6.

Then, insert the universal bracket into the slit of the

actuator and fix the bracket onto the damper with the two

M4 tapping screws.

Figure 6. Attaching the universal bracket

4) Manually rotate the shaft clamp back to the fully closed

position with the gear release button pressed. At this

time, be sure to leave a clearance (approx. 1 mm)

between the shaft clamp and the rotation angle adjuster

(mechanical stopper). Using a wrench, tighten the

fastening nuts of the shaft clamp to completely fix the

actuator.

Figure 7. Complete installation of the actuator body

5) Attach the position indicator ring to the damper shaft so

that the tip of the damper blade and the pointer of the

indicator ring point to the same direction.

Adjust the rotation angle adjuster on the fully open side

depending on the damper rotating angle.

IMPORTANT:

•For Model R30/R31/R35/R36/SDC40 single loop controller (Model with MFB* input) connected to Model

MY6050A1001, automatic setting function of feedback potentiometer is not available. Manually perform the

potentiometer setting. ∗MFB: Motor feedback

•For the controller with time-limit feedback connected to Model MY6050A1001, error may be detected. In such

a case, reset longer time limit.

Connection example for multiple actuators (in parallel operation)

Precautions for parallel operation

•Confirm the total power supply voltage of the actuators to operate in parallel.

•Operating time of each damper may differ due to error. This may result in difficult synchronization of the actuators

operation.

•Parallel operation of the multiple actuators may affect the operation life of the controller contact.

•Due to different operating time, Model MY6050A actuators cannot be combined with Model MY6040A actuators.
