Auxilliary Switches
DA-088N024PA2XP and DA-088N024PX2XP
Figure 13 shows the adjustable switching values for auxiliary switches
A and B.
Figure 13. Adjustable Switching Values for the Dual
Auxiliary Switches.
The auxiliary switch setting shafts rotate with the
actuator. The scale is valid only when the actuator is in
the "0" position on clockwise motion
Use the long arm of the † (AUX SWITCH ADJUSTMENT) to point to
the position of switch A. Use the narrower tab on the red ring to point to
the position of switch B.
Dual in-Line Package (DIP) Switches
For: DA-088N024PXXXP
Raise the protective cover from left to right to locate the DIP switches.
See Figure 2 for the location of the cover.
The factory setting is 0 (OFF).
When mechanical angle of rotation is limited, the self-adapt switch may
be turned ON
so that the limited range will become the new 0 to
100% for the actuator logic. In this case, 0 to 100% is not equal to 90°.
Figure 14. Self-adapt Switch.
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.
The position output signal U is not influenced by the self-adapt
function. The 0 to 10V feedback signal U is always proportional to 0° to
90° (or 90° to 0°).
The factory setting is clockwise.
The direction of rotation switch should match the damper rotation
movement.
Figure 15. Direction of Rotation Switch.
The factory setting is direct acting.
As the clockwise angle of rotation increases, the output voltage
increases.
If the direction of rotation is counterclockwise, the output signal switch
should be set at reverse acting to match the direction of the rotation
switch.
Figure 16. Output Signal Switch.
Manual Override
To move the damper blades and lock the position with no power
present, do the following:
1. Slide the red manual override knob toward the back of the actuator.
2. Make adjustments to the damper position.
3. Slide the red manual override knob toward the front of the actuator.
Once power is restored, the actuator returns to automated control.
