Becker R30-17 - Setting Limit Positions with Rotary Switch (Standard); Upper Stop to Lower Stop Setting (Rotary)

Setting the limit positions with a rotary switch or a locking button for standard
roller shutter application
For adjustment of the limit positions for applications that represent a second escape
route, refer to the chapter Setting and deleting the limit positions for applications that represent
a second escape route [}9].
Intelligent installation management
Completion of installation following automatic setting of limit position "Stop"
Next time the “stop” limit position is travelled to, this position will be provisionally saved as the limit position. Once the limit position
has been detected at this position 3 times in a row without any problems, it will be definitively saved. This normally takes place dur-
ing regular operation.
To complete installation quickly, it is sufficient to travel to the “stop” limit position 3 times in a row from approx. 20 cm.
Limit position status indicator
A brief stopping and restarting indicates that no limit position has been set in that direction of movement.
There are 4 ways to set the limit positions:
• Upper stop to lower stop
• Upper point to lower point
• Upper stop to lower point
• Upper point to lower stop
If the tubular drive switches off prematurely while opening or closing due to an obstruc-
tion, the obstruction can be cleared by reversing a short way and removing the obstruc-
tion. The desired limit position can then be set by opening/closing again.
When first installing using springs and adjusting the limit position "...to lower stop", the
barrel in the lower limit position turns approx. 1/4 of a turn further than usual. In doing so,
the tubular drive is able to automatically detect the use of anti-lifting devices or springs.
The tubular drive switches off automatically.
Upper stop to lower stop
Open to the permanent upper stop.
▻ The tubular drive switches off automatically.
Then close to the permanent lower stop without pausing. During travel, the end posi-
tion status indicator (ESI) must be displayed before the end position is reached.
▻ The tubular drive switches off automatically.
► The limit positions are now set.
