Refer to the Functional Detail in the General Information section for a complete description
of the ED 800 in Power Assist Function.
LATCHED DOOR
If the ED 800 is to be installed on a door which is required to be latched, it is recommended that an
electric strike release or electric latch retraction device be installed. When the ED 800 is installed
on a door with an exit device, the device should be dogged during hours when the ED 800 is turned
on.
If it is not possible to release the strike or retract the latch, the ED 800 must be activated by only
the Push & Go feature. Also, the latch must be manually held retracted when the unit is initially
turned on. This is because the ED 800 performs a "learn cycle" when it is first energized. Part of
the learn cycle requires that the door be opened a few degrees to obtain information about the
amount of force required to open that particular door. If the door is latched during the learn cycle,
the ED 800 will default to the power requirements of a typical 36" wide interior door.
If this is not satisfactory, simply turn the unit off, wait approximately 30 seconds, then turn the unit
back on while holding the latch retracted until the learn cycle is completed.
POWER ASSIST FUNCTION
1. Adjust the "Power Assist/Low Energy" slide switch to the "Power
Assist" position.
2. Adjust the "Door Width" potentiometer to match the approximate
door width. Doors must be between 36 and 48 inches wide for
optimum operation.
3. Adjust the "Opening Force(PA)" potentiometer to obtain the
amount of opening force desired. "MIN" is the least amount of
force required to open the door (approximately 1.5 pounds of force),
and "MAX" is the greatest amount of force required to open the
door (approximately 5 pounds of force).
4. Adjust the "Opening Angle" potentiometer to obtain the
maximum angle of opening to which the unit will assist.
5. Adjust the "Delay Time" potentiometer to obtain the desired
amount of time the door will remain in the Power Assist function
once activated. This is adjustable from 5 to 60 seconds. The delay
time will commence upon activation or when there is no longer any
door movement, whichever occurs later.
6. Adjust the "Push & Go" slide switch as required. When in the
"on" position, a door movement of one inch will activate the unit. If
the user opens the door briskly beyond 45° the Push & Go feature
will abort. This is to conserve heating and air conditioning energy
and to prevent the unit from operating needlessly. When in the "off"
position, the unit must be activated externally.
