Travel times (blinds, roller shutters, etc.)

The travel time is the time which the blind/shutter requires to perform a movement from the very top to the
very bottom and vice-versa. The travel times for UP or DOWN can be determined and input separately. If
the JRA/S receives a telegram to travel upwards or downwards, then the appropriate output is switched
and the blind/shutter moved in the required direction.
The blind/shutter is moved in this direction until the output receives a STOP telegram or the upper or lower
end position and the drive is switched off using the limit switch. If the drive is switched off using the limit
switch, then the corresponding output contact remains closed until the parameterized travel time has
elapsed. In addition, the travel time can be extended using a parameterizable overflow, see the parameter
Disconnect output from power after. Only then is there no more voltage at the output. The overflow time is
not taken into account when a value not equal to 100 % is set for the parameter Slat position on reaching
lower end position. In this case, the output sets the slats according to the parameterized value on reaching
the lower end position.
