System Design: Limit Switches
In combination with UMS 5 or UMS U5 open/close controller
Local controllers
Each UMS 5 controls a drive through outputs 14 and 24.
It is actuated by signals on the local inputs (VA and VZ) from
conventional double push-buttons. Travel direction interlo-
cking and run time limiting are ensured by the UMS 5.
Group and central controllers
Several UMS 5 units can be grouped together by simply
connecting their auxiliary inputs (NA and NZ) in parallel. They
can be actuated jointly by connecting another (higher-level)
controller ahead of them. This creates a
group
.
Group controllers can in turn be grouped together in the
same way and actuated jointly by a higher-level controller.
This further grouping is called
central control
.
Rain, wind and light
The various limit switches are connected to the VA/VZ or NA/
NZ inputs of the central controller.
Safety-related actuation signals
for rain or wind
must be
connected to the auxiliary inputs as continuous signals
. This
ensures that the system is locked out for optimal protection
against user errors.
Actuation signals not related to safety
, such as automatic
shading or twilight operation,
are connected to the local
inputs as momentary pulse signals
.
In this case the system remains fully under control of the
user.
Local controllers
The individual local controllers are ac-
tuated by the group controller and their
own push-buttons
Group controllers
are actuated by the central controller
and push-buttons
Central controller
The central controller is actuated by
sensors and associated limit switches
