Notes
1. TipTime is the time threshold for the Auto Sash to detect
manual movement, to allow manual operation. When
movement is detected within the set times the sash will
automatically drive to the calibrated position.
For example, when the TipTime range is set to 100 ms (min) and
1000 ms (max), and the Auto Sash detects movement for more
than 1000 ms, it will allow the sash to be moved manually to
any position. If the Auto Sash detects movement within the min
and max time settings the sash will automatically drive to the
calibrated position, downward movement will drive the sash
fully closed, upward movement will drive the sash to the mid
position.
2. Stall Detect Sensitivity sets the boundary of the Sash Fault
alarm, where 1-6 = 1-6mm/sec sash velocity. The Stall Detect
Delay is a delay period before the alarm activates.
For example, when the Sensitivity is set to 4 and the Delay is set
to 2 seconds, the Sash Fault alarm will activate 2 seconds after
the sash velocity <4mm/sec.
3. Auto Stop engages the clutch to stop the sash moving when
the sash is manually raised above the mid calibrated position.
The Auto Stop Distance is the distance above the mid position
where the stop will engage. The sash will return to the mid
position after the Auto Stop Delay time.
For example, with the Distance set to 5mm and the Delay set to
2 seconds, when the sash is manually raised the stop will
engage 5mm above the mid position and the sash return to the
mid position after a 2 second delay.
4. Motor Over Current Open and Closed parameters are used to
stop the sash if the motor current exceeds the set values when
the sash is driving.
