25 Low-energy mode
à
Doors set to low-energy mode generally do not require any additional protective devices, if no particularly
vulnerable persons are expected to use the door.
à
With 2-leaf doors, both drives must have been set to low-energy mode.
The Powerturn drive can be operated as a low-energy drive if the following conditions are met:
à
in a disconnected state:
à
The spring's retention force and opening force must be set to <67 N at the main closing edge.
à
The closing time must be set from 90° to 0° using the table below.
X
Once the power is connected, set the value for the "Braking force" parameter so that the closing time is
complied with in the disconnected state.
à
in a electrified state:
à
Static force on the main closing edge is <67 N.
X
The opening and closing force must be set to 60 using the "Opening force" and "Closing force" or FO and FC
parameters.
à
The kinetic energy in the door leaf has to be limited to 1.6 J.
X
The opening time and the closing time of the door must be set accordingly using the parameters "Opening
time" or
O T
and "Closing time”, “Manual closing time” or
C T
and
s6
in line with the table below.
X
The hold-open times (or, oH, OP, HO, oS parameters) must be set to >5 s.
