POINT Guard I/O Overview
Before You Begin
Always observe the following guidelines when using a module, noting that in this
manual we use safety administrator to mean a person qualified, authorized, and
responsible to secure safety in the design, installation, operation, maintenance,
and disposal of the ‘machine’:
•
Thoroughly read and understand this manual before installing and
operating the module. Also refer to the related documentation as necessary,
listed in the
•
Keep this manual in a safe place where personnel can refer to it when
necessary.
•
Use the module properly according to the installation environment,
performance, and functions of the machine.
•
Verify that a safety administrator conducts a risk assessment on the
machine and determines module suitability before installation.
Verify that the POINT Guard I/O firmware revision is correct prior to
commissioning the safety system, noting that firmware information related to
safety controllers is available at

Follow Precautions for Use
ATTENTION:
Safety state of the outputs is defined as the off
state. For complete details of the safety state of inputs, be sure
to review
Safety state of the module and its data is defined as the off state.
Use the POINT Guard I/O module only in applications where the off
state is the safety state.
Serious injury may occur due to breakdown of safety outputs. Do
not connect loads beyond the rated value to the safety outputs.
Serious injury may occur due to loss of required safety functions.
Wire the module properly so that supply voltages or voltages for
loads do
not
touch the safety outputs accidentally or inadvertently.
