Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282*

Introduction

1 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 Pepperl+Fuchs representative.
Mounting, installation, commissioning, operation, maintenance and disassembly
of any devices may only be carried out by trained, qualified personnel. The
instruction manual must be read and understood.
When a fault is detected within the device, it must be taken out of service and
action taken to protect against accidental use. Devices shall 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 Pepperl+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

The devices are available as safe area version (KCD2-SR-*(.LB)(.SP)) where
they can be used as a signal conditioner providing isolation for non-intrinsically
safe applications. Also the devices are available as hazardous area version
(KCD2-SR-Ex*(.LB)(.SP), HiC282*) allowing use as isolated barriers for intrinsic
safety applications.
The safe area versions transfer digital signals (NAMUR sensors/mechanical
contacts) via a galvanic isolation. The hazardous area versions transfer these
signals from a hazardous to a safe area.
The proximity sensor or switch controls a normally open relay output for the safe
area load. The device output changes state when the input signal changes state.
The normal output state can be reversed via DIP switches.
In the KCD2-SR-(Ex)1.LB(.SP) versions, output II can be switched to either follow
output I or to detect faults on the input line (line break, short circuit).
Line fault detection (LFD) can be selected or disabled via a DIP switch.
During an error condition the outputs de-energize.
