7 Operational mode overview
7.1 ED50 door closer modes
7.1.1 Automatic mode
Door closer mode parameter
hd
=0.
Designed for automatic access following pulse
generation by a knowing act device.
7.1.2 Manual mode
Door closer mode parameter
hd
=1.
Designed for doors primarily accessed manually.
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.
TIPS AND RECOMMENDATIONS
Parameter descriptions can be found in
Chapter 18; Parameters.
7.2 Low energy product
7.2.1 ANSI/BHMA 156.19
ED50 operator is configured to meet requirements of a
low energy application per ANSI/BHMA A156.19,
Standard for Power Assist and Low Energy Power
Operated Doors.
7.2.2 Low energy power operated door
A 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.
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
