Description
PFTL301E-0.5KN The Safeguard 400 Series consist of the two product variants; Safeguard 410 and Safeguard
- The difference between these two variants are described below. Description contained in
all other parts of this manual are common for both PFTL301E-0.5KN variants unless otherwise specified.
The hardware for Safeguard 400 Series consists of processor module, sub-modules, sub-racks,
and power supplies.
Common characteristics:
The processor module used is PM150V08 and has the following characteristics:
- The CPU board contains a Motorola MC68020 processor and dynamic read/write memory
(RAM) with ECC (Error Correction Circuit). The memory houses the system software as
well as the user application. The CPU board is PFTL301E-0.5KN delivered with PM150V08 which is a 8 MB
dynamic read/write memory version.
- One slot for flash memory Program Card holding the safety system software.
- Two RS-232-C ports dedicated for printer and MasterView 320
- One port dedicated for connection of Advant Station 100 Series Engineering Stations
- Four slots for communication sub-modules, two slots are configured with MB300
interface.
- Direct access to Fireguard and Autronica addressable detector systems connected via the
communication sub-module slots.

The safety system consists of one central S100 I/O rack where the CPU-module and the I/O
boards are located.
- Direct access to up to 15 S100 I/O boards.
6DIHJXDUG
The safety system consists of one PFTL301E-0.5KN central S100 I/O rack where the CPU-module and I/O boards
are located plus up to two additional S100 I/O sub-racks where I/O boards are located
- Direct access to up to 54 S100 boards.

This is the product variant with only one controller. These are called Safeguard 410 Single and
Safeguard 415 Single. The hardware and functions described in this manual are valid for both
variants with the exceptions described in PFTL301E-0.5KN Appendix A of the Safety Manual
(3BNP000432R301).
Isolation of failures
If a critical failure is detected in one of the safety control branches, the process will continue,
uninterrupted. The failure will be isolated upon detection, thus preventing spurious trips.
Safeguard 400 Series will then operate as a 1oo1D (single) system. Alarm messages and
detailed diagnostic information will be presented to the operator so that the fault can be repaired
quickly.
Fail-safe action
In the very rare case where critical failures are detected in both safety controller branches, a
partial or complete fail-to-safe action is initiated. The fail-safe function in the RDA is to de
energize the field devices connected as critical outputs to the Master Vote 3000 termination
units in the Safeguard 400 Series. In this way ABB Safety fully maintains the philosophy of
fail-safe shut down control.
1.4 Applications
As indicated in Figure 1-1, there is no exact border between safety systems and process control
systems regarding safety application functions (e.i. equipment protection can be performed in
both PSD and DCS). The safety system is normally considered to be a shutdown system taking
action when the process goes outside the safe operating range. This may be due to an event in
the process equipment itself, such as a pipe rupture, a stuck valve, or detection of fire or gas in
the plant. Equally critical are abnormal process conditions arising from loss of control (for
example reaction runaway) or failure in the process control system itself.
Further, the safety and process control systems must interact during recovery from a trip (safety
action) or at normal process start-up. As the process is outside the normal state for a long
interval, the normal cause-effect actions should not be taken. However, to simply bypass these
safety actions during start-up poses serious safety risks at a time when the process state is
normally very unstable. Therefore, the process control and safety systems must communicate to
ensure that safety mechanisms are being applied during the various phases of plant start-up.
This is one main argument for an integrated system design.
The safety systems can be divided into two main application areas:
- Process safeguarding:
PSD (Process Shut Down) system
- Equipment Protection
- Critical Control.
- Plant/Area safeguarding and personnel safety:
ESD (Emergency Shut Down) system
F&G (Fire and Gas) Detection and Protection system.
1.4.1 Process safeguarding
Safeguard 400 Series includes hardware and software constructed to assist in the design of
safety system structures that meet industry regulations for such systems. A large number of pre
defined application solutions for commonly used process transmitters, detectors and actuators
are defined as function block macros.
