The max. close (nudging) speed must always be set
according codes. EN81 requires the energy limit of
E = 10J for closing (E = 4J for nudging), this must
be calculated by the formula
Because of the different speeds of door panels (e.g.
for telesopic doors) the mass m_equ has to be cal-
culated as virtual mass seen from belt.
m_equ = m_antr +
+ sum of (m_panel * (v_panel / v_belt)² )
m_antr virtual mass of operator
m_panel mass of the panel
v_panel speed of the panel
v_belt speed of the belt
The operator mass m_operator is about 30kg
(motor, hanger plate and coupler).
The table below shows the default parameters for
different speed settings. Close and nudging speeds
are calculated according EN81 energy limitation
(Max. mass = m_equ).
If door panel mass m_equ is higher than
Max. mass the next lower speed setting has
to be selected, otherwise the door panels
exceed the energy limit in closing direc-
tion.
The max. door speed setting is calculated with
mass m_equ of 150kg. The close and nudging
speed is then limited to the panel energy of 10J
and 4J respectively.
This door times will also vary depending on:
- Door masses.
- Friction.
- Mechanical adjustements.
- Alignment of landing doors.
- User Interface SW parameters.
The time for coupler and lock movement is about
0.5 sec. in open and close direction (depends also
on various different coupler types).
