1 Introduction
This manual describes the functions of the device named GW1x797 “ 1 channel 8A motor command
actuator” and how to use the ETS configuration software to change the settings and configurations.
3

2 Application
The GW 1x797 motor command actuator is used to control motors on shutters and blinds using an 8 A relay.
The device has 1 channel with an output that has an exchange contact to which two terminals are
connected, one to control the upstroke movement of the shutter/blind, and the other to control the
downstroke movement. Apart from the relay that manages the running of the motor, there is also a relay
connected in series to the first on the line which powers the relay that manages the load so that it is
impossible to interrupt the power to stop the motor from running and that there is a hardware interlock that
prevents the two contacts from being powered at the same time, which would damage the motor it is
connected to. The device is fitted with two front buttons to locally control the motor, 2 two-coloured leds with
night lighting function (amber LED) and a movement in progress status signal (green LED).
On the back of the device there is a button and red physical address programming LED; it is important to
remember that the device must be configured when the shutter/blind is completely open in the upper end
position.
2.1 Limits to the associations
The maximum number of logical associations that the device is able to memorize is 140; this means that the
maximum number of logical connections between communication objects and group addresses is 140.
The maximum number of group addresses that the device is able to memorize is 140; this means that it is
possible to associate the communication objects to a maximum of 140 group addresses.
2.2 Block diagrams
The status of the actuator relay managing the running of the motor depends on the communication objects
that are enabled. For all the foreseen operation modes, the Block object has maximum priority. These are, in
order of priority, the Priority command object, the Safety object, and finally the Switch, Scene, Logic object
(see diag. 2.1).

The activation of the relay is also influenced by parameters that determine the status when the power to the
bus drops below a certain level, or when the device is started up or rebooted. The table below summarises
the priorities described above.

Relay status on reinstatement of power to the bus
Movement/Scene/Stop/Command position object
The relay status on loss of power to the bus refers to the first relay, that is the one that powers the second
relay that manages the load; this status is fixed and can not be modified and consists in the opening of the
relay contact which interrupts the power line that leads to the load.

3 “General” Menu
The Main menu lists all the parameters needed to configure the device settings according to the type of
application required (see fig. 3.1).
Diag. 3.1
3.1 Parameters
¾3.1.1 Operating mode
This selects the actual operation mode for the device, the settings refer to:
•shutter
This enables the device which controls the shutter motor. In this specific case it will not therefore be
possible to control the lath regulation steps as shutters do not have laths.
6

•venetian blind
This enables the device which controls the blind motor. In this specific case it is possible to control the
lath regulation steps as blinds, unlike shutters, do have them.
The item Shutter control movement time (n X 100 ms) and the new menu Automatic movements are
then displayed and will be analysed in chapter 4. The other items are common to both operating modes.
¾3.1.2 Movement maximum time [sec]
Here it is possible to set the maximum time for which the device can power the load. The settings range
from 0 (seconds) to 3000 (seconds).
This time is most important mainly because, as years go by, the motors can wear and the limit switches
can alter; correct settings ensure that under all circumstances the shutter/blind can be raised/lowered
completely before the minimum/maximum level is reached.
It is recommended to set a value of roughly 10% more than the standard travle range time, and in any
case always longer than the travel range time.
¾3.1.3. Travel range time [sec]
Here it is possible to set the movement (stroke) period for the shutter/blind. The settings range from 0
(seconds) to 3000 (seconds).
This setting indicates the shutter/blind stroke time, that is the time it takes for the shutter to open
completely, starting from a totally closed position, and also the time it takes for the shutter to close
completely, starting from a totally open position; it is most important to enter the correct settings as the
intermediate positions of the shutters/blinds are calculated by the device using the settings found in this
parameter.
This time must be less than the setting entered under the item Movement maximum time [sec].
¾3.1.4 Movement in progress feedback
This enables the viewing and use of the Movement feedback object through which the device signals
the type of movement in progress. The settings are:
•deactivated
The device does not signal the movements in progress; the communication object mentioned above is
therefore not visible.
•active
The device signals the movements in progress using the communication object mentioned above. When
the device starts an upstroke movement, it will signal this movement to the bus through the Movement
feedback communication object; it will do the same for a downstroke movement.
¾3.1.5 Forced positioning function
This is to enable the function and make the relative Priority command communication object visible.
The forced positioning function, according to the command received from the bus, forces the device into
a specific condition mode until an forced positioning cancellation command is received; any command
received during the period in which the forced positioning is enabled is ignored, as can be seen in the
block diagram (paragraph 2.2), it has higher priority compared to any other bus command. The settings
are:
•deactivated
The forced positioning function is not enabled and consequently the communication object is not visible.
•active
The forced positioning function is enabled by the Priority command communication object and it is
possible to enable it using a bus command; when it is enabled, any commands received from the bus
(block, alarm, movement command) are ignored until the forced positioning cancellation command is
received.
It is possible to forced positioning the exchange contact status, and also the load controlled by the
actuator according to the command received from the bus, which could be: shutter/blind forced UP
(completely open) or shutter/blind forced DOWN (completely closed).
Should the power to the bus be lost when the forced positioning is enabled, when the power is reinstated
the device will memorise the fact that the forced positioning function was enabled before the loss of
7

power and automatically reinstate the function, putting the load in the condition set by the previous
forced positioning command.
The behaviour of the device at the end of the forced positioning period is indicated under the item
Position on forced positioning, block or alarm disactivation (see 3.1.8).
¾3.1.6 Block function
This is to enable and configure the function and make the Block menu and relative communication
object visible.
The block function, once the relative trigger command is received from the bus, blocks the device in a
specific condition mode until a block cancellation command is received; any command received during
the period in which the block is enabled (except an forced positioning command) is ignored, as can be
seen in the block diagram (paragraph 2.2), it has higher priority compared to any other bus command,
except for the priority command. The settings are:
•deactivated
The block function is not enabled and consequently the Block menu and the communication object are
not visible.
•active
The block function is enabled by the Block communication object and it is possible to trigger it using a
bus command; when it is enabled, any commands received from the bus (scene, alarm, movement
command) are ignored until the block cancellation command is received.
With this function the new Block menu is also visible (see Chapter 4) where the settings used to
configure the function are displayed.
¾3.1.7 Alarm function
This is to enable and configure the function and make the Alarms menu visible.
The alarm function allows the device to function in normal operation mode until specific and settable
conditions occur, at this point the device overrides the status and forces a specific condition status; to
deactivate the alarm function the normal operating conditions much be reinstated. Whatever command is
received (except a trigger block and trigger forced positioning command) during the period that the alarm
status is enabled is ignored which, as can be seen in the block diagram (paragraph 2.2), has higher
priority compared to any other bus command, except for the block and forced positioning commands.
The settings are:
•deactivated
The alarm function is not enabled and consequently the Alarms menu is not visible.
•active
The alarm function is enabled by a bus command; when it is enabled, any commands received from the
bus (scene, movement command) are ignored until the normal operating mode is reinstated.
The new Alarms menu is also visible (see Chapter 5) where the settings used to configure the function
are displayed and where it is possible to enable the communication objects that allow them to be used.
¾3.1.8 Position on forced positioning, block or alarm disactivation
This defines the condition that the load must assume each time the block function, the forced positioning
function and the alarm functions are deactivated. The settings are:
•shutter up
Each time that the block function, the forced positioning function or the alarm functions are cancelled, the
device will move the shutter/blind to the upper end position.
•shutter down
Each time that the block function, the forced positioning function or the alarm functions are cancelled, the
device will move the shutter/blind to the lower end position.
•no movement
Each time that the block function, the forced positioning function or the alarm functions are cancelled, the
device leaves the shutter/blind in the position set by the previous enabled function.
8

•back to previous position
Each time that the block function, the forced positioning function or the alarm functions are cancelled, the
device moves the shutter/blind to the position in which it was found before the function was enabled.
•last received cmd follows / back to prev. position
Each time that the block function, the forced positioning function or the alarm functions are cancelled, the
device moves the shutter/blind to the position set by the last command received (scene, movement,
position command) whilst the function was enabled. If no command is received during the period in
which any of the above listed functions is enabled, the device will move the shutter/blind to the position
in which it was found before the function was enabled.
ATTENTION: Given that the forced positioning, block and alarm functions are all totally independent, in
the event that they have all been triggered, the Position on forced positioning, block or alarm
disactivation settings will only be enforced when all the functions have been cancelled; this means that,
supposing that the forced positioning and block functions have both been triggered, when the forced
positioning function is deactivated the load will be taken to the condition set by the block function which is
still enabled, and only when this too has been deactivated, the position of the shutter/blind will be controlled
by the Position on forced positioning, block or alarm disactivation settings.
¾3.1.9 Scenes function
This is to enable and configure the function and make the Scenes menu and relative Scene
communication object visible.
The scenes function sends two possible commands to the device:
−execute scene, that is a command to create a specific condition
−scene storing, that is a command to memorise the current status (at the moment the command is
received) of the exchange contact, and then reproduce it once the execute command is received
This function foresees 8 different scenes, so the device can memorise /reproduce 8 different conditions
of the load position. The settings are:
•deactivated
The scenes function is not enabled and consequently the Scenes menu and the communication object
are not visible.
•active
The scenes function is active and is managed by the Scene communication.
The new Scenes menu is also visible (see Chapter 7) where the settings used to configure the function
are displayed.
¾3.1.10 Movement object values
This allows you to define which command the upstroke movement and downstroke movement is
associated to, and also the opening and closing of the laths where this option is foreseen. The settings
are:
•“0” = up / ”1” =down
When a Movement communication object telegram is received from the bus with a "0" logic value, the
device will interpret it as an UP command; vice versa when the bit has a "1" value, the device will
interpret it as a DOWN command. If the device is in Blind mode, when a Shutter stop/Louvres step
communication object telegram is received from the bus with a "0" logic value, the device will interpret it
as Open Laths command; vice versa when the bit has a "1" logic value, the device will interpret it as a
Close Laths command. This type of configuration is the same as the one defined by the KONNEX
Standard.
•“1” = up / ”0” =down
When a Movement communication object telegram is received from the bus with a "1" logic value, the
device will interpret it as an UP command; vice versa when the bit has a "0" logic value, the device will
interpret it as a DOWN command. If the device is in Blind mode, when a Shutter stop/Louvres step
communication object telegram is received from the bus with a "1" logic value, the device will interpret it
as Open Laths command; vice versa when the bit has a "0" value, the device will interpret it as a Close
Laths command.

¾3.1.11 Stop minimum time for reversing
This allows you to set the minimum time that must pass between a movement command on the load in
one direction and then in the other. The settings range are provided in the drop-down menu (an interval
of from 100 ms to 5 seconds).
This setting value must be entered according to the type of load being used; there are in fact motorised
shutters which require very little inversion time, that is the minimum time between when the UP contact
is charged and when the DOWN contact is charged, which must be guaranteed in order not to damage
the motor. In this case, if the device receives a command to move in the opposite direction to its current
direction, it will stop all movement, disconnecting the charge to the contact, and after a period of time
equal to that set under this item above, it will charge the other contact and perform the requested
inversion.
¾3.1.12 Shutter control movement time (n X 100 ms)
This defines the multiplication factor of the base time (100 milliseconds) and refers to the length of time
the motor is powered when a lath regulation command is performed. The settings range from 1 to 120.
This means that, if we take for instance a default value of 3, each time a lath open or close regulation
command is received from the bus, it charges the relative motor contact for a period of 300 milliseconds.
This ensures that the requested lath regulation effect is achieved.
¾3.1.13 Night lighting
This is to enable/deactivate the localisation function of the 2 front yellow amber coloured LEDs; the
settings are:
•deactivated
The front yellow amber coloured LEDs will never be enabled, therefore no movement will occur and the
front indicator lights will not be backlit.
•active
The front yellow amber coloured LEDs are enabled when no movement is in progress; in this case the
front indicator lights are backlit by the yellow amber LEDs indicating that there is no movement in
progress, in the case of lack of light in the environment, it also acts as a device localisation light.
¾3.1.14 Local keys behaviour
This enables the use of the local buttons to move the load; the setting are:
•disabled
When the buttons on the front of the device are pressed, this produces no effect.
•enabled
When the buttons on the front of the device are pressed, this has an effect on the device as seen below:
−prolonged pressure on the button (for a period over 500 milliseconds) causes the movement of the
load in the direction indicated on the drawing on the pressed button. In the case where prolonged
pressure is detected whilst another movement is in progress, if this involves an inversion in direction,
the device will stop the movement in progress, and once the time set under the Stop minimum time
for reversing parameter has passed, it will perform the new movement; if the prolonged pressure on
the button does not involve an inversion in direction, the movement in progress will continue until the
travel range time expires.
−short pressure on the button (for a period of less than 500 milliseconds), if there is movement in
progress, causes the movement to be stopped, regardless of whether the button pressed was in the
same or opposite direction.
If there is no movement in progress, short pressure on the button regulates the opening and closing
of the laths (according to which button is pressed), only when the Operating mode is set to Blinds;
on the contrary, short pressure will produce no effect.
¾3.1.15 Position command object
This enables the viewing and use of the Position Command object through which the device is able to
receive the setting commands from the bus relative to the awning/blind percentage position to be
implemented. The settings are:
