Summary of Changes
This publication contains the following new or updated information. This list
includes substantive updates only and is not intended to reflect all changes.
Introduction
This device is intended to be part of the safety-related control system of a
machine.
Rockwell Automation does not accept responsibility for failure of this device if you
do not impalement the procedures that are given in this publication, or if you use
the unit outside the recommended specifications that are listed in this publication.
Description
A valid reset operation concurrently activates instantaneous and delayed safety
outputs. The status indicators of instantaneous outputs CH1 and CH2 and delayed
outputs CHT1 and CHT2 are lighted. At the demand of the safety function and if any
fault occurs, the instantaneous safety outputs de-energize within the specified
response time. The delayed safety outputs open once the delay time has lapsed. If
the time-reset circuit opens during delay timing stops, the time lapse and the
delayed contacts open instantaneously.

IMPORTANT Before installation, perform a risk assessment to determine
whether the specifications of this device are suitable for all
foreseeable operational and environmental characteristics
of the machine to which it is to be fitted. At regular
intervals during the life of the machine, check whether the
characteristics foreseen remain valid.
WAR NIN G: Danger of serious injuries. Misuse can result in
malfunction.
• Only authorized and trained personnel can start up, assemble,
or retrofit the device.
• Installation must be in accordance with the following steps.
WAR NIN G: Danger of serious injuries.
Incorrect installation or manipulation can result in serious
injuries. Do not defeat, tamper, remove, or bypass this unit.
ATTENTION: If any malfunction or damage is present, do not
attempt to repair. Replaced the unit before machine operation
is allowed. Do not dismantle the unit.
IMPORTANT The safety inputs of these products are described as
normally closed (N.C.), that is, with the guard closed, the
actuator in place (where relevant), and the machine able to
start. You must prevent exposure to shock and/or vibration
in excess of those specifications in IEC 60068 part: 2-6/7.
Adherence to the recommended inspection and
maintenance instructions forms part of the warranty.
IMPORTANT All information complies with the state of this publication
and is subject to change without notice.
