6.2 Operating specifications
6.2.1 ED900
7 Operational mode overview
7.1 ED900 door closer modes
7.1.1 Automatic mode.
Door closer mode parameter
hd
=0.
Door opens automatically following pulse generation by
a knowing act device or by push/pull.
7.1.2 Manual mode.
Door closer mode parameter
hd
=1.
Designed for doors primarily accessed manually.
7.2 Low energy product
7.2.1 ANSI/BHMA 156.19.
ED900 operator is configured to meet requirements of
a low energy application per ANSI/BHMA A156.19, U.S.
Standard for Power Assist and Low Energy Power
Operated Doors.
7.2.2 Low energy power operated door.
A manual door with a power mechanism that opens the
door upon receipt of a knowing act activating signal,
does not generate more kinetic energy than specified in
ANSI 156.19, and is closed by a power mechanism or by
other means.

7.1.3 Power assist.
• Available only in door closer mode (
hd
=1), manual
opening drive support is automatically adjusted to
operator size.
• Parameter
hA
sets door activation angle for power
assist function. Once angle reached, drive support
provides easier manual opening of the door.
• Parameter
hF,
power assist function. Parameter
values greater than 0 provides additional opening
force.
• Parameter
hS
, power assist function support for
door in closed position.
Required system safety, as a low energy application, is
achieved utilizing the following design factors:
• Reduced dynamic door panel contact forces
• Reduced static door panel contact forces
• Low driving speeds
• Force limitation
