HA8-LP Manual V. 4.0
Low Energy Operator Adjustment to ANSI A156.19 standard
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 - Inch(mm)
Up to 100 lbs (45kg)
Up to 140 lbs (64kg)
39 (914) & Less
2.0 sec
2.3 sec
Door Leaf Width - Inch(mm)
Up to 110 lbs (50kg)
Up to 150 lbs (68kg)
42 (1067)
2.3 sec
2.7 sec
Door Leaf Width - Inch(mm)
Up to 120 lbs (55 kg)
Up to 160 lbs (73kg)
48 (2119)
2.8 sec
3.2 sec
For doors of other weights and widths, use the formula below:
Latch check
The door must not close through the final 10 degrees in less than 1.5 seconds.

Adjustments are provided for Opening speed, Back Check speed, Activation Time (Hold Open), Activation Delay, and
Overload current with LED indicator.
Detection of an Overload
Current is persisting for longer than 2 seconds will cause the door to close. See below recommended procedure for
adjustment of the control:
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. However, if the door moves from close to Back Check in less than 4.0 seconds, the LED will flash as
the door closes 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 2 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.
