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 congu-
rations.
The motor run time can be limited to prevent motor overload
due to mechanical jamming or other causes. A convenient
and congurable automatic closing function ensures that
skylights or other xtures are not inadvertently left open. In
louvre blind mode the louvres can be adjusted precisely or
automatically returned to a dened angle after switch-off.
Applications
Roller shutters and louvre blinds, shutters, skylights, smoke
extraction hoods in re 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 congured 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 indenite
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,

Motor controllers www.schalk.de
Motor controllers
for example from vertical to horizontal (privacy on/off). The
motor run time for this angle adjustment can be set from 0.1
to 1.4 s. A triple button press initiates the full motor run time
(setting range 3 to 240 s).
If automatic closing is enabled, the drive starts moving in
the closing direction after the set closing time delay. The
time-out is started by the signal on the VA local input.
If the signal on the VA input is active longer than 2 seconds,
the closing time is doubled. In louver blind mode a reverse
pulse is congured instead of the closing function, so that
the louvers are automatically reset after the motor stops.
Central push-button motor control mode (Z) enables simple
central control in relatively small systems without a higher-
level group controller. The auxiliary inputs can be actuated by
push-buttons in the same way as the local inputs, but they
take priority.

SJ Only UMS 5/U5: Louvre blind privacy
(short button press sets privacy on or off; triple button press to adjust
blind position)
Z Central push-button motor control
(all inputs operated by push-buttons)
U4 Only UMS 5P: mode for downwards compatibility to UMS 4
* In mode GM or GJ, relay output M1 or M2 (14 or 24) is continuously closed as long as an active signal
is present on an auxiliary input. This enables override actuation (with local inputs blocked) by sensors
(wind sensor, rain sensor, etc.).
In mode „U4“ the UMS 5P behaves as the former model UMS 4, and therfore can be used as a repla-
cement device or for extension of older equipment. In this mode, the motor only stops when button is
pressed at VA or VZ, and doesn‘t change direction.
Automatic closing time setting „autom. Rücklauf“:
This sets the automatic closing time, reverse pulse time or louvre run time:
In motor control mode (M):
Time for automatic closing function 3 s to 30 min or Off (function disabled)
In louvre blind control mode (J):
Duration of reverse pulse 0.1 to 1.3 s or Off (function
disabled)
In louvre blind privacy mode (SJ):
Louvre run time 0.1 to 1.4 s

UMS U5 (230V AC):
The UMS 5 (230V AC) model supports the assignment of different phases for the supply voltage, the local inputs and auxiliary
inputs.
Attention! For UMS U5 supply voltage and control voltages must be identical (same phase).

UMS 5P (230V AC)
The UMS 5P auxiliary inputs are electrically isolated. The auxiliary inputs can thus also be controlled from different phases of
the power network. Allowed control voltage: 12V - 230V AC or DC.
The electrically isolated auxiliary inputs of the UMS 5P should not be permanently actuated when driven with
230V, since this leads to increased heating.

Several motors controlled by one UMS 5 - decoupled with MGR U2
Attention! Roller shutters or louver blind motors with mechanical limit-switches must as a rule not be electrically
connected directly in parallel, because due to the different motor running times the limit-switches of some
motors may be reached while other motors are still running. The motors that are already switched off
would then receive inductive voltage at the counterwinding from the motors that are still running, which
can lead to destruction of the limit switches. The devices of the MGR series provide an extremely simple
method of achieving a (functional) parallel circuit: e.g. an MGR U2 is simply inserted upstream of each
motor.

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

UMS 5 / UMS U5 function diagrams
All operating modes and set motor running time:
local inputs are edge-triggered and time-monitored
Motor running time in pushbutton mode: local inputs
are level-controlled and not time-monitored
Operating modes M and J with motor running time:
auxiliary inputs are level-controlled and time-monitored
Modes GM and GJ or motor running time set to „T“:
auxiliary inputs are level-controlled and not time-monitored
When a reverse pulse time is set, the reversal is started or
retriggered after releasing VA
tvu = Switchover pause (0.6s) between K14 and K24
for motor protection (mechanical stress release). As one local
button is active, the other local button is ignored:
As one local button is active, the other local button
is ignored. NA overrides NZ:
Louver blind mode: local inputs are level-controlled in respon-
se to short press of button and edge-controlled when button
held down
Set louver blind counter-run: counter-running (tg) is triggered
by timeout of VZ or by manual stop
Operating mode Z with motor running time: auxiliary
inputs are edge-controlled and time-monitored
Mode SJ (does not apply UMS 5P):
Actuating a local input once, the motor will start turning in the selected direction with the set duration (0.1 to 1.4s). Actuating
a local input 3 times in direct succession, the set motor run time (3 to 240s) is started. Closing run time (K24) lasts 25%
longer than the opening run time (K14), to ensure a dened starting position for the next turn.
U4 mode (applies only to UMS 5P): When actuating VA and VZ
alternately, the motor will not directly turn direction but stops
the motor. The auxiliary inputs behave as in mode Z.
