instAllAtion step 6: enabling operation/completing installation
For safety reasons the Control Unit is supplied with
„deadman“ pre-setting for ventilation. You require the
software for switching over to „latching“. It is abso-
lutely necessary to ensure that all safety-relevant re-
quirements for the „latching“ mode are guaranteed
according to the information provided by the manu-
facturers of the connected opening components.
RWA systems require a logbook, in which all important master data have
to be entered prior to operation enable and all operational events during
the period in operation. The logbook is part of the system documents and
must be stored and available to authorized staff at all times.
We advise to perform an insulation measurement of the cable network
before enabling operation of the plant and to keep a written record of
this test.
Provided that the factory default conguration has been changed using
the system software, all alterations have to be taken into
account in the operating manual. It might be required to prepare an ope-
rating manual for non-specialist users that is easy to follow and well
understandable.
In case of re the system saves lives. Therefore
immediately remedy or have any fault or mal-
function remedied by specialists!
Depending on the storage period the back-up accumu-
lators require some time to be fully charged. Therefore,
bridging time (see chapter „
Data sheet“) for the power
failure might not be ensured after connecting the
back-up accumulators and the back-up accumulators
rst need some charging time in mains operation
to reach the maximum charge status (min. 8 hours).
The Control Unit must not be enabled for operation
unless all system components work properly. This also
applies to system components that do not come under
our producer responsibility or whose installation had not
been commissioned but are still components of
the RWA system. Upon completion of the installation,
all functions of the Control Unit must be checked
for correct functionality with utmost care. Even
if there is no fault indication this does not mean that all
components function faultlessly.
Warning
Before the installer is allowed to enable the operation of the Control Unit,
the complete performance range of the system must be checked with
utmost care. The chapter „Troublshooting anD repair“ provides support
for the localisation of possible faults and malfunctions.
On the last page you nd an overview of all external connections where
the current assignments can be entered.
Modications of the system using the system software should take place
after the complete installation of the Control Unit and all components
being connected. When required, the system conguration and status
can be saved or printed using the system software. In the case of faults
or malfunctions of system components it might also be necessary to
thoroughly check the system conguration (computer to be connected
using system software).
Follow the instructions in the chapter „safety in-
struCtions“.
Before changing the operating mode check and pay
attention to danger zones at the window!

troublshooting and repair
All functions and system components that are important for the
RWA operation are constantly monitored for faults. A fault indication
signals the type of fault and, respectively, possible errors when connecting
system components (such as back-up accumulators, detectors, drives)
during commissioning of the Control Unit.
The overview below details some of the possible faults and problem
cases and their causes. „Indicator B“ means the green operating indi-
cator which does not light up in case of a fault. The yellow “Indicator S”
signals the type of fault.
You nd a list of all indicators in chapter „
leD´s anD Dip switChes“ - on
the previous page.
