MSG1 compact
Motor Control Unit
1. Description
The Motor Control Unit MSG1 compact controls 230 V drives, e.g. shading or
window motors. The relay at the motor output is a low-wear zero-crossing switch.
The device is equipped with inputs for central control and for a manual switch. The
central input can be set to dead man's switch or lock and is suitable e. g. for timers,
push buttons or control systems. An unlocked twin push button is connected to the
switch input for manual operation. This input is equipped with time-automated but-
tons (step operation/lock).
Functions:
•Outputfora230 V AC drive (Up/Down)
• Use as a central, group and single controller
•Central input up/down 12...28 V DC (with priority) e.g. for switches, controls
• Setting the central control unit to "Dead man" or "Lock". As long as voltage is
present at the central input, the manual operation is blocked
•Manual operation by connecting an unlocked double push-button to the
Input "Local".
Push-button timer automatic: Inching mode (press for less than 1 second):
Drive inches, for example for positioning slats on shutters.
Drive mode (press for longer than 1 second): Drive travels automatically to
the final position
•Lockout inputs for Local Up, Local Down, Central Down
• Direction change pause 1 second

2. Installation and start-up
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components within the device.
• VDE regulations and national regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for the intended purpose described in this manual. Any
improper modification or failure to follow the operating instructions voids any and
all warranty and guarantee claims.
After unpacking the device, check it immediately for possible mechanical damage.
If it has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when as-
sembled and after conclusion of all installation and operational start-up tasks and
only in the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may
occur after publication of these operating instructions.
2.2. Safety notice for automatic functions
WARNING!
Risk of injury from automatically moving components!
Parts of the system can be started by the automatic controls
and be a danger to persons.
• No persons may remain in the travelling range of parts
driven by an electric motor.
• Adhere to the relevant building regulations.
• Ensure that the return path/access to the building is not blocked
if spending time outside the building (danger of being locked out).
• Correctly decommission the system for maintenance and
cleaning work.
If there is a power outage, the system does not work. Therefore, shadings should be
moved to a save position if there are anticipated weather conditions, for example, if
this has not already been done by the automatic function (product protection).
If the power supply is removed, the connected drive switches off. When the power
is restored, the consumer remains switched off until a new movement command is
received by the actuator.

The internal voltage (9 ... 12
V DC) is used to supply the
inputs. When using several
motor control units which
receive the same central
command, the "-" connec-
tions must be bridged for
potential equalisation.
In this way, a MSG1 com-
pact can supply up to 100
additional motor control
units with power for central
control.
Each terminal contact may
be loaded with a maximum
of 10 A.

2.4. Notes on mounting and commissioning
Device must not be exposed to water (rain). This could result in the electronic being
damaged. A relative air humidity of 95% must not be exceeded. Avoid bedewing.
3. Operation
3.1. Central operation
At the central input of the MSG1 compact e. g. an automatic control unit, a timer
or even a normal unlocked twin push button (Up/Down) is connected, to control the
drive connected to the output. As long as voltage is applied to the central input, the
local input is disabled.
If there are "Up" and "Down" movement commands at the central input at the same
time, the drive moves up (secure position).
Set operating mode
The central control unit can be set to the operating modes "Lock" (default) or "Dead
man".
Dead man mode: As long as voltage is present at the input, the drive output is closed
and the engine is running. As soon as there is no voltage left at the input, the drive
output opens and the motor stops.
Lock mode: When voltage is applied to the input for at least 1 second, the drive out-
put closes for 4 minutes and the motor runs for this time. On Command in the op-
posite direction stops the drive.
By simultaneously pressing the Up and Down buttons at the local input, you can
switch between the operation modes:
1. Press the buttons Local-Up and Down simultaneously for 5 seconds,
in order to set the device to readiness for change.
OR
Switch the operating voltage briefly off and on again.
After the mains voltage is connected, the device is also in a state of readiness for
change.
2. The device is now ready for change and it indicates the currently active mode via
the mode-LED.
LED flashes: Dead man mode
LED on: Lock mode.
3. To change the mode, please press Up and Down again for 5 seconds.
4. The device leaves the state of readiness for change after 60 seconds of inactivity
or if you press Up and Down again for a short time.
3.2. Individual operation (local)
The manual individual operation of the drive connected to the output is performed
via an unlocked twin push button at the local input. This input is equipped with time-
automated buttons.
• By a short button stroke, the drive can be exactly positioned (e.g. slats of
blinds).
• At a button stroke longer than 1 second, the drive travels in lock mode to the
end position (motor running time 4 min).
• A short stroke of one of the two buttons stops the travel.
As long as voltage is applied to the central input, the local input is disabled.
4. Disposal
After use, the device must be disposed of or recycled in accordance with the legal
regulations. Do not dispose of it with the household waste!
