ADA Adjustments
Adjust the Ditec Automatic HA/FA-8 operator to the ANSI A156.19 standard for low energy
operated doors.
The following specifications are based on neutral air pressure conditions.
Opening Speed
Minimum opening time to back check or 80 degrees is 3 seconds or longer. Total opening time shall be 4
seconds or longer.
Closing speed
The minimum closing time to latch check depends on the size and weight of the door as follows:
Door Leaf
Width
– in (mm)
Up to 100 lbs (45kg):
Up to 140 lbs (64kg):
36 (914) & Under
2.0 secs
2.3 secs
Up to 110 lbs (50kg):
Up to 150 lbs (68kg):
42 (1067)
2.3 secs
2.7 secs
Up to 120 lbs (55kg):
Up to 160 lbs (73kg):
48 (2119)
2.8 secs
3.2 secs
For doors of other weights and widths, use the following formula:
Where W=Weight of door (lbs), D=Width of door (in) and T=Closing time to latch check (sec).
Latch check
The door must not close through the final 10 degrees in less than 1.5 seconds.
Adjustments of 09720N Controller for ADA Doors
Adjustments are provided for Opening Speed, Back check Speed, Activation Time, Activation Delay, and
Overload Current with LED indicator. A two- position switch allows selection of Closing Speed.
Detection of an overload - current is persisting for longer than 2 seconds will cause the door to close. The
recommended procedure for adjustment of the control is as follows:
1. Turn the Overload (current) control fully clockwise to increase the current limit to maximum and
prevent any detection entirely. This setting can be used to inhibit the overload detection /
shutdown feature.
2. Adjust Opening Speed as desired. Note: that the control has a built in time reference of 4.0
seconds. Operation of the door will not be affected, but, if the door moves from closed to back
check in less than 4.0 seconds, the LED will flash as the door begins to close to indicate that the
opening speed may be a little fast.
3. Lock or obstruct the door and apply an Activation Trigger. Turn the Overload control counter
clockwise until the LED becomes steadily illuminated, to indicate detection of excessive current.
The control may be turned counter clockwise a little more to ensure positive detection. After two
seconds the door will close.
4. Adjust the Activation Time (hold open) as desired, Minimum of 5 seconds
5. Adjust the Activation Delay Time as desired. This will depend on the distance of the activation
devices to the door
6. Operate the slide switch to select the desired Closing Speed.
