SAFETY MANUAL SIL KFD0-RSH-1.4S.PS2
Introduction

Introduction
1.1
General Information
This manual contains information for application of the device in functional safety
related loops.
The corresponding data sheets, the operating instructions, the system
description, the Declaration of Conformity, the EC-Type-Examination Certificate,
the Functional Safety Assessment and applicable Certificates (see data sheet)
are integral parts of this document.
The documents mentioned are available from
www.pepperl-fuchs.com
or by
contacting your local Fuchs representative.
Mounting, commissioning, operation, maintenance and dismounting of any
devices may only be carried out by trained, qualified personnel. The instruction
manual must be read and understood.
When it is not possible to correct faults, the devices must be taken out of service
and action taken to protect against accidental use. Devices should only be
repaired directly by the manufacturer. De-activating or bypassing safety functions
or failure to follow the advice given in this manual (causing disturbances or
impairment of safety functions) may cause damage to property, environment or
persons for which Fuchs GmbH will not be liable.
The devices are developed, manufactured and tested according to the relevant
safety standards. They must only be used for the applications described in the
instructions and with specified environmental conditions, and only in connection
with approved external devices.
1.2
Intended Use
This signal conditioner is a loop powered safety relay module with a logic input
and two different relay outputs:
It can be used as an interface in output loops for fire and gas systems classified as
SIL3. The safe state in this application is
e
nergized
t
o
s
afe (ETS). Output I with
two relays in parallel must be used, no fuse available.
It can also be used as an interface in output loops for ESD (
E
mergency
S
hut
D
own) systems classified as SIL3. The safe state in this application is
d
e-energized
t
o
s
afe (DTS). Output II with two relays in series must be used. An
additional fuse in series to the relay contacts is available (see chapter 3).
With both outputs in combination a non safety application for dual pole switching
(DPS) is possible.
Additionally a test input for proof tests is available. The proof test checks if each
single relay is working correctly.
The device is usually mounted on a DIN rail in cabinets with access for qualified
personnel only.
