2.3 GEZE MBZ300 modular principle
Hardware conguration
àThe modules can be installed on a standard top-hat rail (TS 35). After correct connection the module is recog-
nised immediately and integrated automatically into the system via the BUS. Faults and errors during connec-
tion are indicated through rapid ashing of the status displays or through the fault display (see chapter5.1.5).
Software conguration
àFire sections and ventilator groups can be congured in varied ways thanks to the modular system.
àThanks to the possibilities of the software conguration and the extensive area of application of the modules,
special installations in the control panel are hardly necessary for special applications.

àPower pack 10 A, PS10A
àPower pack 24 A, PS24A
Minimum and maximum equipment
àThe minimum equipment consists of 1 switching power supply unit, 1 power module PM, 1 control module
CM and 1 drive module DM.
àThe maximum equipment can contain up to 64 BUS modules at a max. of 72 A (3 switching power supply units
with 24 A each). If more capacity is required, several units can be congured via the software as a combined unit.
3.2.1 Determining the correct equipment of the control panel
Switching power supply units and power modules
The number of switching power supply units and power module extensions PME required results from the
maximum drive current. The power module PMis always required. One PME each is required for every further
switching power supply unit.
XFrom the maximum current requirement you determine:
àNumber of switching power supply units (10 A or 24 A, max. 3 switching power supply units)
àNumber of power module extensions (PME, each 24 A max., 1 per switching power supply unit, max. 1 PM + 2 PME)
àBattery types for emergency power supply
Batteries for emergency power supply
XObserve the following when selecting the batteries:
àBack-up time for emergency power operation in case of power failure
àMax. drive current
àNumber and types of the modules
àNumber of detectors connected
The emergency power supply has to be guaranteed for 72 h and motor operation then still has to be possible for
a subsequent 180s (2x opening and 1x closing) at the maximum motor current.
Typical own consumption of the modules (with battery voltage 24 V)
àPower module PM 16.1 mA
àPower module extension PME 0.0 mA
àControl module CM 20.6 mA (incl. 3 detector line caps)
àSensor module SM 12.6 mA (incl. 3 detector line caps)
àDrive module DM 5.3 mA

Drive modules DM for ventilator groups
One drive module DM makes max. 10 A (with MBZ300 N8 max. 8A) possible for the connection of a ventilator group.
Calculation examples:
Current required Drives modules 10 A Switching power supply units Power modules
16 A 2 (20 A) 1x 24 A 1 (PM)
30 A 3 (30 A) 1x 24 A + 1x 10 A 2 (PM + PME)
Control module CM and sensor modules SM
One control module CM is always required. It monitors the rst re section. 1 sensor module SM is required for
each further re section.
Weather module
A weather module WM is required if the ventilation is to be controlled via wind and rain sensors or if wind-direc-
tion-dependent opening or closing is required in the case of re.
Relay module ERM
The relay module ERM makes the notication of error and operating statuses possible. It has 6 potential-free
detector relays that can be congured with the system software.
Housing
The housing size results from the number and layout of the modules, the number of the required switching power
supply units and the size of the batteries.

3.2.5 Changing the module conguration
As long as the system has not yet been congured with the PC, the number, type and order of the modules are
recognised automatically after every restart and integrated into the standard conguration (self-teaching function).
If the assignment of the drive modules to the re sections has to be changed subsequently (for example because
an additional SM module has been installed), the system has to be recongured.
XPress the RESET push button on the CM module for approx. 20 s until all the operating LEDs ash.
The modules are now readdressed automatically.
XOnly connect or disconnect modules in de-energised state, switch mains voltage and battery o rst.

3.3 Connection of the MBZ300 control panel
The following three connection types exist for the modules:
àSupply voltage
àPower module PM
àPower module extension PME
àDrive module DM
àBUS connection (ribbon cable)
àAll the modules (only connection PME – PM on the module top, remaining modules on the bottom)
àExternal components
àDetectors, drives etc. (plug-in terminals on the module top)
3.3.1 Connection of the supply voltage
The following must be connected (if not already done in the factory):
àInternal power supply
àBatteries (also have to be placed in the central housing)
àSwitching power supply units to the power module PM and, if necessary, power module extensions PME
àDrive modules DM to the supply voltage
All the other modules do not require a connection to the supply voltage. The following diagrams show the con-
nection for:
à1power module PM with 1switching power supply unit 10 A or 24 A (with MBZ300 N8 max. 8A)
à1power module PM with 1power module extension PME and 2switching power supply units 10 A or 24 A
à1power module PM with 2power module extensions PME and 3switching power supply units 10 A or 24 A
The number of drive modules DM that can be connected to a switching power supply unit with PM or PME de-
pends on the maximum current consumption at the respective switching power supply unit.
Application examples:
àSwitching power supply unit 10 A with 1DM for max. 10 A current consumption (for MBZ300 N8 max. 8A)
– or –
Switching power supply unit 10 A with 2DM for two ventilator groups with max. 5 A current consumption each
àSwitching power supply unit 24 A for 2 DM with max. 10 A current consumption each
– or –
Switching power supply unit 24 A for 4DM, if the max. current consumption does not exceed 10 A per DM
and 24 A in total

3.3.2 Connection of the internal BUS connection
The BUS connections of the modules for the ribbon cable are located on the bottom (only connection PME to
PM on the module top). The modules can be connected to each other irrespective of their function in the system
(digital BUS system). If the BUS system is distributed on several top-hat rails, a special-version BUS cable (special
length) has to be used.
In order for the modules to work properly they have to be located correctly (see Chapter 7.1).

Installation
The cable cross-section for the drives depends on the type and number of drives. However, it has to be at least
1.5 mm2. A cable up to max. 2.5 mm2can be connected to the drive module DM, larger cross-sections must be
connected using additional series terminals.
Calculation equation for cable cross-section (drives)
Cable cross-section = Cable length × Total current of all the drives / 73
Examples for maximum cable lengths depending on cable cross-section and total current of drives:
1 A 2 A 4 A 6 A 10 A
1.5 mm2100 m 50 m 25 m 16 m 10 m
2.5 mm2180 m 90 m 45 m 30 m 18 m
4.0 mm2280 m 140 m 70 m 45 m 28 m
10.0 mm2–360 m 180 m 120 m 72 m
This calculation takes a tolerable drop in voltage of approx. 2 V over the cable into account.
3.4 Installing the CAN module
The system must be congured for this application using the system software.
With the MBZ300 N8, the CAN module can only be used for the minimum conguration (1×PM, 1×CM, 1×DM).
The CAN module is used for connecting several control panels to one control and triggering unit via CAN-bus.
One CAN module is required for each control panel to be connected via CAN bus.
The system can manage a max. of 30 control panels linked by CAN-bus.
Inserting the CAN module
XBriey remove all the connections on the control module
CM (internal bus, top plug-in terminals with external con-
nections etc.).
XLoosen the control module from the top-hat rail.
XInsert the CAN module (1) into the control module CM from
below.
The fault display of the control module also signalises possible
problems with the CAN-bus link.
If the CAN module needs to be pulled out, press this slightly
above when pulling it out.
