System overview
3 System overview
3.1 System description
REGARD 7000 is a modular control unit for gas and fire alarm systems. The control
units consist of one or more Docking Stations, each of which can contain up to
8 modules. The REGARD 7000 is a system with distributed intelligence. Each
module has the intelligence required for its function. A REGARD 7000 system can
also be wired to create a system of up to 6 remote units (docking stations and
modules). The complete system can have a maximum of 24 Docking Stations and
can control 1536 channels. Input and output channels may be distributed as
required (1 to 1535 up to 1535 to 1).
The modules are either input or output modules. Every module generally has 8
channels. All modules have their own intelligence and operate autonomously. The
system is designed so failure of a module only affects the modules dependent on
the failed module, i.e. the faulty module only generates a secondary fault in the
modules that expect data from the faulty module. Other modules are not affected. In
addition, every fault in the system is signalled on each Docking Station via the fault
relay (System Fault Relay, SFR). All modules can be replaced during operation
without shut-down of the supply voltage.
3.2 Safety design
REGARD 7000 is designed in accordance with the requirements for SIL2 and for
SIL3 with the applicable system layout.
REGARD 7000 is designed as a system with distributed intelligence that does not
require a master controller (masterless). The modules communicate with one
another deterministically (predetermined) using a proprietary safety Ethernet
network protocol. All bus devices send their current data in a data packet to all other
bus devices once every second. Bus devices that derive actions from this
information (e.g. relay modules) expect a valid data package from every module

Configuration
Diagnostic
,QVWUXFWLRQVIRUXVH_ 5(*$5'
System overview
once every second. The modules accept no more than 2 faulty data packets in
succession. If more than 2 faulty data packets in succession are received, a fault is
triggered and the fault relay (SFR) in the Docking Station is activated.
Due to the communication without a master device (masterless), there is no
component in the system whose failure would trigger a failure of the complete
system (Single Point of Failure). The modules are time-synchronised throughout
the system by a module that is automatically selected when the system is started.
In the event of a fault in this module, the time function is automatically transferred to
another module in the system and a fault is signalled via the SFR. All modules not
influenced by the faulty module continue to operate.
Special states in the system, such as Inhibit, are also displayed by the special state
relay (SSR) at the Docking Station.
The alarm is triggered a maximum of 3.3 seconds after measurement of an alarm
condition.
The system continuously monitors the correct function. Every system fault results in
drop-out (normally energized) of the respective fault relay on the Docking Station.
Systems with requirements as per SIL3 can be implemented with REGARD 7000
by using a structure with redundant channels.
Dräger recommends selection of fault-tolerant configurations for safety-relevant
applications, such as acknowledgement of alarms using 2 independent switches.

System overview
Dräger recommends performing a dashboard firmware update when expanding
REGARD 7000 with modules with a firmware version > 1.00.xx. The latest version
of the dashboard firmware can be downloaded free of charge via the
ServiceConnect® web portal (www.serviceconnect.draeger.com). Using dashboard
firmware that is not up-to-date means that not all features of the new modules may
be fully supported.
3.4 Intended Use
REGARD 7000 is a modular control unit for gas and fire warning systems.
The REGARD 7000 system continuously monitors production facilities for the
following conditions:
– The presence of gas and/or vapour concentrations in the ambient air.
– The outbreak of fire.
The REGARD 7000 system has the following functions:
– The power supply of the connected transmitters and sensors.
– The evaluation of all measurement and status signals.
– The actuation of the associated alarm devices.
All measured values and important system parameters can be displayed
continuously on one or more dashboards and sent to primary control centres via a
gateway module.
3.5 Limitations on use
REGARD 7000 is not designed for use in process control.
The REGARD 7000 network is only permitted to be used for REGARD 7000
communication. Connection to a general IT network is not permitted, for example.
3.6 Approvals
REGARD 7000 is approved under IEC/EN 61508:2010 and EN 50402:2017 for
SIL 2 applications or for SIL 3 with the corresponding plant setup. For details of the
configuration and system layout for SIL 2 or SIL 3 see the Dräger REGARD 7000

4.1 Docking Station
The Docking Station forms the basis assembly of the REGARD 7000 system. Up to
4 or up to 8 REGARD 7000 modules can be plugged into the Docking Station.
The Docking Station manages the power supply of all its modules and via the
modules it indirectly powers the associated transmitters (for transmitters with a
max. power consumption of 500 mA; an external power source is required for
greater power requirements).
The Docking Station is used for all system communication between the modules
and to and from other Docking Stations.
In addition, it forms the beam for accommodating the Terminal Blocks.

4.2 Modules
4.2.1 4-20 mA Input Module / HART®
Input module in 2 variants (with or without HART®) for connection of up to eight 4-
20 mA transmitters. A 4-20 mA module shows the current values from 4 mA to
20 mA in linear form on the measuring range (0 to the end of the measuring range).
From firmware version ≥01.01.01 the current values 4-20 mA can also be mapped
to a completely or partially negative measuring range. Regions of measurement
range underrun and overrun and special states and warnings of the transmitter can
be configured. For further information, see the following chapter: "Port configuration
4-20 mA Input Module / HART®", page 88
Monitoring functions – input voltage monitoring 18-30 V
The SFR is activated for voltage underrun; the
power supply is shut down in case of voltage over-
run and the SFR is activated, then a restart is
required.
– Total current monitoring
Docking Station 4-Slot:
shut-down at >10.2 A (max. 12 A), then a restart is
required.
Docking Station 8-Slot:
shut-down at >20.4 A (max. 22 A), then a restart is
required.
– Temperature monitoring
Shut-down of the Docking Station and activation of
the SFR, then a restart is required.

Application notes
One module 4-20 mA Input / HART®always provides 8 physical ports. A Port
configured with a channel ID forms an input channel. Even so, unconfigured and
thus unused Ports occupy the corresponding number of Ports in the overall system.
WARNING
Missing gas alarm
With supply power to a connected transmitter via the 4-20 mA Input / HART
module, note that the current consumption of the transmitter depends on the line
length and the cross-section of the transmitter supply lines. In very unfavourable
circumstances this may mean that the supply voltage approaches the shut-down
limit of the channel and the current monitoring limit will be exceeded with a signal
current. In this case a measured signal may result in the shut-down of the channel
and as a result a module error that will also be signalled on the Docking Station via
the SFR. This will suppress a gas alarm configured in this current range. The same
behaviour is also found with the connection of multiple transmitters for the total
current monitoring of a module for all channels. In the most unfavourable case this
may result in shut-down of the complete module and failure of the associated
channels.
►When designing the supply currents for the transmitters, the supply voltage per
channel must be at least 20 mA below the permissible channel short-circuit
detection current (500 mA or 250 mA) and at least 160 mA below the module
short-circuit detection current (2 A). In case of doubt, during commissioning the
supply current to the single channel and the total supply currents on all channels
of the module must be tested to ensure compliance with the above conditions.
Use of signal duplicators
For the use of REGARD 7000 and one additional signal receiver, 4-20mA signal
duplicators can be used.
