Specifications/Instructions

Intelligent Component Series

Direct Coupled Damper Actuator

(Spring-Return Type)

Model MY8045A

General

Model MY8045A direct coupled damper actuator is a

motorized spring-return type actuator to open/close a

damper.

Model MY8045A communicates with a controller via SAnet

(Azbil Corporation’s communication protocol).

Features

•Intelligent Component Series Model MY8045A

communicates with a controller via SAnet, and thus

position control signal/position feedback signal is input to

/output from the controller.

•Manual open/close function allows easy adjustment

without power supply.

•Torque limit circuit inside the actuator automatically

stops the damper in fully closed or open positions.

•Low power consumption allows energy conservation.

•Large torque is assured despite compact, lightweight

design.

•Spring-return actuator automatically closes the damper

in 0 % position in case that the power is down.

•Rotary switch on the front surface easily changes the

motor rotating direction.

•Simple physical structure facilitates installation on most

types of the damper shafts.

•Model MY8045A damper actuator conforms to all the

applicable standards of CE Marking.

IMPORTANT:

This product is applicable to 50 Hz utility

frequency, not to 60 Hz utility frequency.

Address Setting (Addressing)

To SAnet interface module, the damper actuator Model MY8045A2001 and other Intelligent Component Series devices

including ACTIVAL and ACTIVAL PLUS are connected via SAnet. Set address for the terminal devices (Intelligent Component

Series devices) so that the SAnet interface module can recognize all the terminal devices connected. Follow the procedure

below to set the address. For details regarding address setting (addressing), ask our sales/service personnel.

Setting with service pin switch (manual switch):

1) Start addressing operation* of Data Setter or PC-MMI. Then, press the service pin switch to change the operating direction

as: L →R →L or R →L →R. Perform the operation within 5 seconds.

2) Address is set within 5 seconds after pressing the service pin switch.

∗Communication trouble and duplicated address cause addressing error. Check that address is correctly set in Data Setter or PC-MMI.

Setting based on SAnet ID:

With Data Setter or PC-MMI, enter the SAnet ID (on the SAnet ID label) and address number to set. The SAnet ID label is

attached on a side surface of the actuator, as shown in Fig. 12.

Figure 12. Locations of the labels

IMPORTANT:

Address setting must be performed by our service personnel or qualified expert.

Adaption (Setting Rotating Angle)

CAUTION

•Before performing Adaption, check that the rotating direction of the product is correct.

When the rotation angle of the actuator is adjusted or changed, the actuator needs to memorize (adapt) the adjusted/changed

rotation angle. Note that Adaption is performed by our service personnel.

(To our service personnel: Refer to Engineering Manual of Intelligent Component Series for SAnet Communication (AB-6685))

Synchronisation (Position Alignment)

Damper position which the actuator controls disagrees with the actual damper position if actuator mounting position on the shaft

is changed. In such a case, the actuator requires Synchronisation so that the damper position controlled by the actuator and the

actual damper position agree (synchronize). Note that Synchronisation is performed by our service personnel.

(To our service personnel: Refer to Engineering Manual of Intelligent Component Series for SAnet Communication (AB-6685))

Setting of the Maximum Rotation Angle

To set the maximum rotation angle of the damper actuator to 90°or narrower, use the mechanical stopper supplied with the

product. The mechanical stopper allows to set every 5°increment within 30°to 90°range.

Setting procedure

1) Attach the mechanical stopper to a position according to the range to be set. Insert the mechanical stopper into grooves

provided on the damper actuator, as shown in the figure below.

2) Fix the mechanical stopper with the accessory tapping screw. There are 3 tapped holes (indicated with ‘x’) provided on the

scale of the damper position. Insert the tapping screw into either one of the holes, through the mechanical stopper.
