Blinds and switch actuator RMG 8, blinds actuator JMG 4
and switch actuator module RME 8 - EIB theben
As of: Apr-06 (Subject to change without notice) Page 3 of 36
1 Function Properties
The RMG 8 EIB blinds and switch actuator and the RME 8 / RMX 4 extension modules can be used
as a
•Drive controller for blinds, roller shutters and sunshades, and as a
•Switch actuator, e.g. for lighting, ventilation and the like.
If used as a lighting controller, the individual channels of the RMG 8 and RME 8 / RMX 4 devices can
be parameterised:
•As a switch actuator (on/off without delay)
•As a delay mechanism for on/off operations (delay times can be individually set)
•As a pulsing function (activation restricted by timeout)
•As an automatic time switch for staircase lighting with cut out early warning (after the preset
time has elapsed, the light is switched off temporarily (for 0.25 s) and then switched on again for
30s).
Several inhibit and control objects enable a remote control of the connected devices, e.g. central
raising or lowering of blinds/roller shutters/shading devices or central inhibiting of individual or all
switching channels.
Via three safety objects, sunshades or sight protection devices can be retracted/extended to a defined
position, for example in the case of a storm or rain.
The application software distinguishes between standard and expert users (refer to the chapter Expert
Application).

1.1 Advantages
•Modular device concept with as many as 8 driving or 16 switching channels.
•On-site device operation, e.g. an installation test of the drive mechanisms / lighting for example is
also possible without bus voltage.
•LED status indicators of the outputs: Switching status, keyboard lock, higher priority
•Every driving channel can be parameterised to act as two switching channels (except for JMG 4).
•Every switching channel can be programmed to act as a convenient timer.
•The staircase lighting period can be extended by repeated actuation of the switch.
(when a person has to clean the staircase, etc.). Cut out early warning function in compliance with
DIN 18015-2.
•Simple input of the execution times in the ETS.
•Large scope of functions due to 47 objects.
•Even with traditional drive mechanisms any desired position can be approached due to the
slippage compensation.
•Forced object (all drives up or down with highest priority) e.g. for cleaning windows or in the case
of fire alarms.
•Flexible reaction to security telegrams: Can be set for each drive mechanism individually for the
beginning and end of the safety status.
•The behaviour in the case of a bus failure and in the case of a recovery of the bus/mains voltage
can be selected.
•Feedback of the position of the drive mechanism and the switching channel status for building
visualization.

1.2 Areas of Application
The RMG 8 EIB switch actuator and the RME 8 / RMX 4 switch actuators module are suited for the
following applications (examples):
•Control of awnings, blinds, roller shutters as well as various sunshades and sight protection
devices
•Control of dormer windows and ventilation flaps
•Shading, lighting and heating greenhouses and winter gardens
•Lighting buildings and staircases
•Delayed activation/deactivation of groups of lights
•Short or long pulses for end-of-break gongs, toilet flushing installations or ventilation systems
1.3 Differences between RMG 8 and JMG 4
As opposed to RMG 8, JMG 4 is a pure drive controller and not a switch actuator.
The drive functions of the JMG 4 are completely identical to those of the RMG 8 but the switching
capacity of 8 A of the JMG 4 is lower (refer to the chapter Technical Data).
The two devices can be expanded with an RME 8 or RMX 4 module.
The extension modules can always be parameterised as desired as a drive controller or as a switch
actuator for light etc.

3.3 Communication Objects
3.3.1 Introduction
The basic setting for each channel is the parameterization as a drive controller or as a switching
channel with 2 outputs.
The function and thus the type and designation of the individual objects depend on the use of the
corresponding channel, i.e. drive, roller shutter, blinds, switching channel, timer and the like.
In this case, we will use channel 1 as an example.
3.3.2 Overview
3.3.2.1 Channel Parameterised as a Drive Mechanism

3.3.3 Description of the Objects
•Object 0
Name
(refer to the overview)
Function
Drive 1 up/down Raise roller shutter/blinds with "0" and lower them with "1"
Channel 1.1 switch Switch on the relay with "1" and switch it off with "0"
Channel 1.1 staircase
time switch
Activate automatic staircase time switch with "1" and deactivate it with "0".
As soon as the parameterised time has elapsed or when a "0" is sent to the
object, the relay switches off after a cutout early warning.
cutout early warning: The relay switches off for ¼ of a second, switches on
again for 30 seconds and then switches off completely.
Channel 1.1 impulse Activate the impulse with "1" and deactivate it with "0".
As soon as the parameterised pulse time has elapsed or when a "0" is sent to
the object, the relay switches off.
Channel 1.1 delayed
ON/OFF
If a "1" is sent to the object, the relay switches on after the parameterised
period of delay.
If a "0" is sent, the delay refers to the switch-off time.
Special cases:
A "0" sent during the switch-on delay period or a "1" sent during the switch-
off delay period interrupts the procedure.
•Object 1
Name
(refer to the overview)
Function
Drive 1 stop A "1" or a "0" sent to the object stops the raising or lowering operation.
Drive 1 step/stop If the blind is moving, it will be stopped.
Otherwise, a short movement of the slats is performed (step mode).
The direction of the "step" is defined by sending either a "0" or a "1" to the
object.
Steps will not be performed after the maximum possible slat turn position has
been reached ("Full Slats turn" parameter).
Channel 1.1 state Feedback of the current relay status, e.g. for building visualization.
Example: A delayed switch-on operation is started, the feedback object is set
when the relay is switched on following the elapsed delay period.

•Object 4
Name
(refer to the overview)
Function
Drive 1 auto comfort Sending a "1" to this object inhibits the functions Drive 1 height and Drive 1
slats.
This function is used to prevent the manipulation of the blind position by
third-party interference and thus to maintain a preferred position of the slats.
The up/down functions (objects 0 and 1) remain operational.
Inhibit channels 1.X Sending a "1" to this object inhibits channel 1.1 and channel 1.2
(see table 1-5, Parameter „Dependence on object Inhibit channels 1.X“)
Annotation:
The reaction of the objects 5 to 39 is identical to that of the objects 0 to 4 and they represent either the
drives 2 to 8 or the channels 2.1 to 8.2.

•Objects 40, 41, 42
Name
(refer to the overview)
Function
Central priority 1, 2
and 3
Security objects:
A security object enables an aimed reaction of the drives to a specific
situation with a high priority (refer to the appendix Priority Order of the
Drive Controller).
Example:
A safety object is connected to a wind sensor.
A drive connected to a textile sunshade is parameterised to react to this
security object.
For as long as a "0" is being sent, the standard operating status is assumed.
In the case of a storm, the wind sensor sends a "1" to the security object and
the sunshade is immediately retracted to the parameterised safety position.
IMPORTANT: A security object may be controlled by one device only. Otherwise different
commands may cancel each other.
Annotation: Reading the security objects i.e. with “read value” function of ETS software:
If the security status was initiated by cyclical monitoring, the value of this
object will remain 0
•Object 43

3.4.2 Drives General
Table 1-2: Parameters on the "Drives general" tab
Designation Values Description
Security 1 – 3 (objects) without cyclical monitoring
with cyclical monitoring
The last telegram always
determines the security status.
If a security object has been
assigned an important alarming
function, a check is performed
whether the alarm sensor sends data
periodically.
If the sender fails, the security
status is taken up.
Example (see below).
Cyclical monitoring of
all 3 Objects 1 ... 255
[x 1min]
Input: 1 to 255 If the sensors connected to the
security objects send cyclically, the
cycle time, i.e. the time interval
between 2 telegrams must be
entered here.
Recommendation: The monitoring
time of the actuator must be twice
as long as the cycle time of the
device to be monitored.
Example:
If the air speed meter sends to the
security object 1 every 5 minutes,
set the monitoring time to 10
minutes.

** In typical applications, the reaction after a recovery of the bus voltage is set identical to the reaction after a
recovery of the mains voltage without bus voltage.

Parameters for the staircase time switch
Time base for staircase
timer
1 sec, 10 sec, 30 sec, 1 min To attain a maximum of flexibility,
the staircase lighting time is
calculated from a time base and a
factor
Factor for staircase
timer
1 ... 255 x Time base
Keyboard input 1 to 255 The staircase lighting time is equal
to the time base multiplied by the
factor.
Example:
Time base 10 s x factor 2 is
2 x 10 s = 20 s
As soon as this time has elapsed, a
cutout early warning is issued, i.e.
the light is switched off for 0.25 s
and then switched on again for 30s.
After this, the feedback is sent (obj.
1). (The cutout early warning
intervals (0.25 s and 30s) are
preprogrammed and cannot be
changed).
