Set dead times
Options:

Standard: The dead times are deactivated.

User-defined: On some sun protection systems, dead times of the blind/shutter mechanics may occur.
They can be caused by aging processes of the blind/shutter, e.g. mechanical load. In such cases, it
may no longer be possible to adjust the blind/shutter to precise positions. The following parameters
appear for the compensation of various dead times of the blind/shutter.
68 2CDC 506 051 D0204 | JRA/S
Standard
User-defined
Dead time blinds/shutter from bottom
until moving up in ms [0...5,000]
Options: 0...5,000
This parameter specifies the compensation time which the blind/shutter requires after a travel
telegram until the first upward movement.
Examples
The slatted curtain is in the lower end position (= 100 % down). The travel telegram UP is
received. The motor shaft begins turning. However, the slatted curtain remains in its lower end
position until the slatted curtain begins the UP movement after a time X ( = dead time).
Dead time of slat from 100% closed
until slat turn in ms [0...5,000]
Note
This parameter is available exclusively in the operation mode Control with slat adjustment.
Options: 0...5,000
This parameter specifies the compensation time, which is required after a slat adjustment telegram
from completely closed (= 100 %) to the first tilt/adjustment of the slat.
Examples
The slats are completely closed (= 100 %). The telegram Slat adjustment OPEN is received. The
motor shaft begins turning. However, the slat remains closed until the slat begins the
tilt/adjustment after a time X (= dead time).
