General information
The UMS electronic controllers are general-purpose AC motor
controllers for clockwise or anti-clockwise operation. They
support both one-button and two-button motor control.
The overriding auxiliary inputs allows several UMS units to be
grouped together in group control or central control configu-
rations.
The motor run time can be limited to prevent motor overload
due to mechanical jamming or other causes. A convenient
and configurable automatic closing function ensures that
skylights or other fixtures are not inadvertently left open. In
louvre blind mode the louvres can be adjusted precisely or
automatically returned to a defined angle after switch-off.
Applications
Roller shutters and louvre blinds, shutters, skylights, smoke
extraction hoods in fire protection systems, door drives,
valve drives, etc.
Operation
The UMS is actuated by standard push-buttons with no need
for mechanical interlocking.
The desired operation direction is selected by a short pulse
(momentary-action signal) from a push-button connected
to the VA (local input for Open) or VZ (local input for Close)
input. The drive runs to its end stop and the configured time
expires.
A subsequent pulse on the VA or VZ input while the drive is
running stops the motor. For
one-button motor control
it is
also possible to actuate both local inputs at the same time
with just one push-button (not in SJ mode). With this actua-
tion arrangement, each button pulse changes the direction
(Open–Stop–Close–Stop).
The
auxiliary inputs
NA (Open) and NZ (Close) allow any desi-
red number of drives to be operated simultaneously in the
opening or closing direction, regardless of their current state.
When actuated by the auxiliary inputs, the motor runs only
as long as the actuation signal from the higher-level group
controller is active. The NA input has priority when NA and
NZ signals are active at the same time. The local inputs are
blocked as long as NA or NZ is active.
When the UMS is used as a
group controller
, there is no time
monitoring of the auxiliary inputs. This allows the lower-level
controllers to be held in the desired position for an indefinite
period (e.g. wind sensors).
In
louver blind mode
the drive is stopped immediately after a
short pulse is applied to a local input. With a longer pulse the
drive continues running to the end position. This enables lou-
ver angle adjustment by short button presses. In one-button
louver blind mode, the direction of motion is not altered by a
sequence of short pulses. Here again, this makes it easy to
adjust the louvers.
In
SJ mode (louvre blind privacy)
a short push-button signal
on the VA or VZ local input changes the angle of the louvers,
