Figure 1: DA-088N Series Damper Actuator
Product Description
This document describes the hardware installation procedures for the
direct-coupled mounting of the DA-088N Series damper actuators.
General Installation Requirements
For proper installation and subsequent operation of each actuator, pay
special attention to the following recommendations:
-
Upon unpacking the product, inspect the contents of the carton for
shipping damages. Do not install damaged actuators.
-
Avoid areas where corroding, deteriorating or explosive vapors,
fumes or gases may be present.
-
Ensure that all equipment is installed according to local, regional,
and national regulations.
Personal injury or loss of life may occur if you do not follow a
procedure as specified.
Equipment damage or loss of data may occur
follow a procedure as specified.
Take reasonable precautions to prevent electrostatic
discharges to the controller when installing, servicing or
operating the controller. Discharge accumulated static
electricity by touching one's hand to a well-grounded object
before working with the controller.

When turning the self-adaptive feature on or after the software reset with the feature on, the actuator will enter a five-minute calibration cycle as the actuator adjusts to the rotation limits of the system. A software reset happens after power on or may be caused by electrostatic discharge (ESD) at levels of 2kV and above. - Page 6 Dual Auxiliary Switch Setting Mechanical Range Limitation and Self-Adapt Feature For DA-088N024FX2XP, DA-088N024PA2XP, DA-088N024PX2XP only.
