HAUTAU RAZ 908 User manual

Product description
The SHEV control unit is intended to be used as a power supply
and control device for the connected equipment (refer to section
“Equipment overview”). The smoke and heat exhaust control unit
HAUTAU RAZ 900 contains all the electronics needed to control
24 V DC drives for windows and smoke vents: in the event of fire
and for general ventilation. In case of power failure, the emergency
power supply guarantees the operation of the SHEV facility for at
least 72 hours.
Features
Opening in an emergency situation:
Manually by fire pushbutton, automatically by smoke and heat
detector or third-party activation.
Closing in the event of an emergency:
Manually by SHEV-CLOSE button (Reset) inside the fire
pushbutton.
Daily ventilation and exhaustion:
By ventilation pushbutton “OPEN-STOP-CLOSE” (continuous
opening) and automatic closing by superordinate wind/rain
sensor.
The included features depend on whether the system operates as
an SHEV control unit or merely as a central ventilation unit and on
which modules have been incorporated.
The smoke and heat exhaust control unit RAZ 9… has been
designed as a modular central control unit. The maximum output
current of the power supply is indicated by the label RAZ 908, while
the expansion stage of the groups is identified by the designation
RAZ 908-.
Its basic configuration consists of a housing with screw plate as
well as a top hat rail, a transformer, a rectifier module with filter
capa citors, a load module, a group module, a smoke and heat
exhaust ventilation module, a smoke detector module, and
battery packs.
The number of group modules corresponds to the maximum
power output of the central unit. Sharing this power output with
other groups is not possible. The number of smoke detector
modules corresponds to the number of smoke detectors
(max. 10 detectors/module). The maximum output current of the
power supply or the maximum breaking capacity of the modules
may not be exceeded.
The SHEV control unit is designed to run on emergency power
for 72 hrs.
While the central ventilation units LZ 9.. are constructed in the
same way as the SHEV control units, they lack the modules
RWA 9, RM 9, LAD 9 and the battery packs.

CAUTION
The safety of personnel requires that the
following instructions be observed.
Incorrect installation may result in severe or
fatal injury!
The control unit complies with the state of
the art. This applies to performance, material,
functioning and the safe operation of the control
unit.
Mortal danger by electric shock!
The smoke and heat exhaust control
unit operates with 230 V AC / 50 Hz.
Mortal danger if coming into contact
with cables that are live.
During service/maintenance work at
the unit, the supply voltage has to be
disconnected via isolating link at all
poles. Protect the system against
unintentional re-starting. The isolating
link must be clearly marked. The mains
fuse must not exceed the rated current
of 6A. Pull off the connecting plugs of
the emergency power battery packs.
Make sure that all potential-free inputs
of the wires are disconnected from the
power supply.
Risk of crushing and pinching!
To avoid misuse, a risk assessment
acc. to Machinery Directive 2006/42/EC
is required at the installation site.
Protective measures are to be applied
according to EN 60335-2-103/2016-05.
The mounting of the control unit has to be
performed by trained, qualified and safety-
conscious electrical staff according to these
installation and operating instructions. These

Installation information
Make sure your shipment is complete prior to commencing
installation. Please notify your supplier immediately in case of
any irregularities.
Connect all components only in accordance with the terminal
connection diagrams included with the central unit and the
drives.
Strictly adhere to all DIN, VDE, government safety organisa-
tion and state building regulations (for example VDE 0100,
VDE 0833, VDE 0800, BGV).
The introduced external wires that conduct voltages in excess
of 33 V AC or 60 V DC must be connected immediately next
to the terminal screws in such a way that they cannot come
into contact with other live components when they are loos-
ened (e.g. by tying them off).
The mains connection may only be established with cables
that have been approved according to DIN VDE 0250-xxx.
All wires except the feeder wire conduct 24 V DC and must
not be laid together with electric power lines (follow VDE regu-
lations). In any case, the wiring type must be coordinated with
the responsible authority (fire department, TÜV, fire protection
authority, etc). All maximum wire lengths and cross sections
must correspond with the technical specifications. Observe the
maximum possible connection options of the control unit.
The position of the central unit and the fire pushbuttons
must also be coordinated with the responsible fire protection
authority (observe state building regulations). Use suitable
mounting material.
When installing the drives, please pay attention to the occur-
ring forces.
Never wire a star-wired network, but always proceed from fire
pushbutton to fire pushbutton, from smoke detector to smoke
detector, from heat detector to heat detector, and from drive
to drive.
Make sure to connect shunt and terminating resistors for
central smoke and heat exhaust ventilation and alarm system
loops.
Two monitoring diodes (1N 4007) must be installed in the last
conduit box in front of the drive and in accordance with the
terminal connection diagram.
Smoke and heat exhaust ventilation systems must be serviced
at least once a year by the trained personnel of a company
specialised in smoke and heat exhaust ventilation and in ac-
cordance with all statutory regulations (building code and state
building regulations).
Finish by checking all functions as well as function and oper-
ation displays on the central smoke exhaust unit and the piv-
oting range of the drives. Complete the assembler’s certificate
included in the control book and forward the request form
and the corresponding envelope to the operator of the central
smoke exhaust unit.
All drawings, installation and operating instructions
and the control book must be kept with the central unit.
Please store these documents in their entirety in the
central smoke exhaust unit for future reference.

Wire lengths and cross sections
Calculation formula:
Cable cross section [mm2] = total current consumption [A] x max. wire lengths [m]
73
Attention:
The clamping points in the control system are designed
for wire cross sections of up to 2.5 mm2. For larger cross
sections, reduce the cross section immediately in front of the
control unit. To prevent electric shock, connect the ground
wire first before connecting any other lines such as the mains
supply line or any external lines. Observe all applicable VDE
regulations.
The wires of the drives may not be extended and have to
be connected directly in a conduit box, or, depending on
the type of drive, to the overload cutoff or the synchronous
module. The maximum wire lengths from the power source
(SHEV/central ventilation unit or power supply) to the last
conduit box (or overload cutoff, synchronous module)
have to be in accordance with the wire cross sections
used and with the maximum power consumption for each
drive group. When using the drives in safety equipment for
smoke removal or smoke control, perform wiring in accor-
dance with the functional integrity classes E30 or E90 of the
Model Wiring Guideline (MLAR).
Security systems need line monitoring. Lines with the
appropriate number of wires for the supply of the drives
and line monitoring have to be provided. The green/yellow
protective conductor must not be used as a line monitor.
Mounting of the control unit
The SHEV control unit has to be installed at a safe place, where
it is protected against fire and smoke effects. The RAZ 900 has
to be mounted in such a way that it is easily accessible for the
maintenance staff (e.g. ensure installation at eye level). It must be
possible to open the door all the way. The label “Smoke outlet”
has to be applied at a suitable place.
Use suitable mounting material to attach the control unit at the
designated borings.
Make sure to properly earth the housing. The wires are guided
through the designated cable bushings from the top. Ensure
a clear labelling of the wires of all components, which will be
connected to the RAZ 900, as well as the feeder wires of the
power supply. This is necessary for the proper assignment of
the connections in case the modules have to be replaced.

Technical specifications
Rectier module
GLR 9/8, 9/24
The rectifier module is used to supply the control unit with
power. It is screwed directly next to the transformer on the
screw plate. The wires are connected via terminal screws and
following the terminal diagram. The transformer connector
is slipped on via cable lugs. The central unit is overload and
reverse battery protected.
A short circuit at the “+” and “-” terminals of the 24 V DC feed
lines in the control unit triggers the transformer’s mains fuse
and the battery pack fuse.
This will result in complete failure.
In this case, all LEDs in the central unit, the fire pushbuttons,
and the ventilation pushbuttons will turn off.
The
transformer is used to provide 230 V AC supply
voltage to the central control unit. It consists of a 21 V AC
power coil and a 27 V AC loading coil. The mains terminals
and the mains fuse are installed on the transformer. The
value of the mains fuse is:
8 A – power supply unit T 1.6 A
16 A – power supply unit T 3.5 A
24 A – power supply unit T 5.0 A
Switch to emergency power operation without disruption

Overview of the major components and modules (cont.)
Load module LAD 9.1
Is used to create the charging voltage and for monitoring the
battery pack connection.
The load module is fed by a separate transformer coil via a
fuse 1 located on the module. A potentiometer 2 is used to set
the charging voltage. The load module monitors the battery pack
and mains connection and issues an error in case of a disruption.
The yellow LED on the load module will come on as soon as the
mains and battery pack connection is not in order. The module
will switch off the voltage supply to the ventilation control system
in case of a mains voltage failure. The sensor at the end of the
PTC cable is positioned close to the battery back (see image),
while the other end is connected to the PTC plug 3 on the load
module. If the PTC sensor measures a temperature above 0 °C
in the area of the battery pack, the charging voltage is 27,6 V.
Temperatures below 0 °C will increase the charging voltage
to 30 V. Jumper J2 4 is used to enable/disable the charging
function, while the potentiometer 6 is used to set the minimum
discharge voltage (pre-set at the factory). This requires that a
voltage of 19,2 V be applied between GND and pin 7 and that the
potentiometer 6 be set to the level where the LED is barely on/
goes out.

The group control module GS 9 is used to control drives.
The signals issued by the smoke and heat exhaust ventilation
bus 6 are given the highest priority. The signals issued by
the ventilation bus 5 are given the second highest priority.
The signals issued by the ventilation pushbutton bus 7 are
given the lowest priority.
If an SHEV OPEN command is given, the motor output will
be switched to OPEN again every 2 minutes for a duration of
30 minutes.
The motors are connected to a 3-pin plug-in terminal 1.
The terminal 3 of this plug-in terminal is intended to monitor for
cable break and trigger an EMERGENCY STOP.
The motor output is protected by a fuse which is integrated into
the guard circuit.
Cable break in the area of the motor lines and EMERGENCY
STOP operation is indicated by a yellow LED 8 (which flashes
during emergency stop operation).
A potentiometer 3 can be used to change the operating mode
of the module:
- When the potentiometer is set to zero, the operating mode of
the ventilation pushbutton is “OPEN-STOP-CLOSE”,
- A different potentiometer position means operating mode
“OPEN-CLOSE”.
The set voltage value determines the time during which the
drives will be moving towards the “OPEN” position. The STOP
button is without function when the timer is switched on. The
running period does not interfere with the smoke and heat
exhaust ventilation functionality.
The running period voltage is measured at the contacts 9.
The voltage values are assigned to the following running
periods in “ON” direction:
To ensure observance of guideline ZH1/494, install EMERGEN-
CY STOP pushbuttons on windows that are less than 2.5 m in
height. The design of these EMERGENCY STOP pushbuttons
must comply with standard DIN EN 60204.
The devices used to protect against crushing hazards and the
EMERGENCY STOP button used as an “opener” are connect-
ed in series and integrated into the motor guard circuit (see
drawing). When combined with the GS 9 module, they provide
the following functions:
- If the direction in the module is switched to “OPEN”, the
disruption of line 3 is only defined as a “malfunction” in the
central control unit.
- If the direction “CLOSE” is switched as a ventilation function
(includes ventilation pushbutton, superordinate ventilation,
wind/rain sensor, delayed smoke and heat exhaust venti-
lation reset) and wire 3 is interrupted (equal to actuation of
EMERGENCY STOP pushbutton), the GS 9 module will trigger
an internal malfunction. The drives in this group will be stopped,
while the internal malfunction remains active and is indicated
in the fire pushbutton as well as on the module. Actuating
the module in “OPEN” direction will reset the error message
mentioned above and allow the drive to move again during the
next “CLOSE” operation.
Pressing and holding the “Reset” button in the fire pushbutton
will disable the EMERGENCY STOP function.
Releasing the reset button will enable the EMERGENCY
FUNCTION again.
If a connected timer is switched on, the ventilation function
will be blocked after an emergency stop has been triggered.
Pressing the reset button in the fire pushbutton or on the RWA
9 module of the central control unit will enable the ventilation
function again.
An additional reset button is installed on the smoke and heat
exhaust ventilation bus of the group module in the central
ventilation units LZ 9 to reset the EMERGENCY STOP function
manually (see drawing below). In the event of an EMERGENCY
STOP, the control unit must be reset by issuing an “OPEN” or a
reset command (in combination with a timer).

Is used for signal analysis and monitoring the fire pushbut-
ton wires. The SHEV OPEN and RESET wires are monitored
for breakage and short circuits.
Description
There is a 6-pin plug-in terminal on top of the SHEV module
RWA 9 that is used to connect the fire pushbutton 7.
The outputs “Display OK”, “Display Alarm” and “Display
Malfunction” are overload protected.
The wires “SHEV OPEN” and “RESET (CLOSE)” are
monitored for disruptions and short circuits.
A yellow “ERROR” LED 8 will light to indicate an error in
the area of the fire pushbutton. In case of emergency power
operation the yellow “ERROR” LED 8 will flash.
The red “ALARM” LED 9 will be lit when the “OPEN” signal
is active on the smoke and heat exhaust ventilation bus,
while the output “Display Alarm” will be activated for the
SHEV pushbutton. Pressing the RESET button in the SHEV
pushbutton or on the smoke and heat exhaust ventilation
module will block the ventilation function for a minute.
An active error signal on the smoke and heat exhaust ventila-
tion bus will result in the disabling of the output “Display OK”
and the enabling of the output “Display Malfunction” (flashes
during emergency power operation).
The RESET button !D will activate the SHEV OPEN signal
on the SHEV bus.If the jumper w is set, each malfunction
will trigger an alarm.
Installation
Voltage is supplied by a 4-pin terminal r via strands of the
same size 2.5 mm².
The SHEV pushbutton is connected to a 6-pin plug-in
terminal 7 according to the terminal diagram. The internal

When a smoke detector has been triggered, smoke detec-
tor module RM 9 will issue the “OPEN” signal on the smoke
and heat exhaust ventilation bus.
Technical specifications
Description
A maximum of 10 RM 523 smoke detectors can be
connected to the loop of one smoke detector module.
The smoke detector connection is monitored for disruptions
and short circuits.
Another option is to connect a central fire alarm system,
which, however, requires that only smoke detectors or only
one central fire alarm system be connected to one module.
The green LED 3 will turn off in the event of a central
control unit malfunction or emergency power. When the
smoke detector is triggered, the red LED will be lit 2.
If the ”CLOSE“ signal is active on the SHEV bus, the voltage
supply to the smoke detector loop will be cut off to reset
the smoke detector. At the same time, a malfunction signal
is prevented from being issued on the smoke and heat
exhaust ventilation bus.
Installation
Voltage is supplied by a 4-pin terminal 6 via strands of the
same size 2,5 mm².
The wires to the smoke detector loop are connected to the
2-pin plug-in terminal 1 according to the terminal diagram.
The internal wiring of SHEV bus (RB) 5 and ventilation bus
(LB) 4 is connected via 3-pin jumpers.

Wind/rain module WR 9
The wind/rain module counts the impulses issued by the wind trans-
mitter and attributes them to the wind force. The module will also
transfer the signal issued by the rain sensor to the internal bus.
Description
A wind/rain alarm will be triggered after a start delay every
time the wind force exceeds a certain set point. A wind/rain
alarm will also be triggered when the rain sensor input is
active; however, without the start delay.
When the wind force falls below the set point and the rain
sensor signal is inactive, the wind/rain alarm is reset after a
certain switch-off delay. The signal issued by the rain sensor
is transferred to the internal bus.
To adjust the set point of the wind/rain module, slip on the
jumper 3 and turn the potentiometer 2. Setting jumper 4
to “Z” activates the “CLOSE” signal on the LB1 bus 6.
Setting jumper 4 to “A” activates the “OPEN” signal on the
LB1 bus 6.
Installation
Install the wind transmitter in a suitable location unsheltered
from the wind. Follow the terminal diagram or the included
control system to connect the wind sensor. When connecting
the WR 9 to other control elements, make sure these
elements are completely discharged and the emergency
power supply is switched off. In the presence of wind, the
display or the volt meter must show a value.
The display must be adjustable when the jumper 3 is
slipped on and the potentiometer 2 is turned.
Voltage is supplied by a 4-pin terminal 7 via strands of
the same size 2,5 mm². The internal wiring of the ventila-
tion buses (LB1) 6 and (LB2) 5 is connected via 3-pin
jumpers.

must not be affected by, for example, structural measures
or stored goods.
Maintenance
Smoke and heat exhaust ventilation systems must be
serviced at least once a year by a company specialised in
smoke and heat exhaust ventilation and in accordance with
all statutory regulations (building code and state building
regulations).
To guarantee a reliable emergency power supply, have the
used battery packs checked and, if necessary, replaced on
a regular basis. The battery packs must be replaced no later
than every 4 years. Dispose of the battery packs properly as
required by all applicable legal regulations.
The inspection plate on the central unit must be renewed,
and a control book must be kept.
We recommend that you conclude a service contract.
Maintenance
If components have to be checked, repaired or replaced,
please contact the manufacturer. Use only original spare parts.
Modifications of connections are permitted only within the limits
of the connection options.
Disposal
Dispose of this product, when it has reached
the end of its service life, in accordance with
the provisions of the Electrical and Electronic
Equipment Act.
Before working on electrically powered windows and dome
lights, make sure to set them to the desired position. They
must be disconnected via isolating link at all poles and
safeguarded against unintentional re-starting. The isolating
link must be clearly marked. This step allows you to
disable the ventilation function while performing work on
the windows.Observe the maintenance and operating
regulations for power-controlled windows, doors, and gates.
