POINT Guard I/O Overview
Verify that the POINT Guard I/O firmware revision is correct prior to
commissioning the safety system. Firmware information for safety I/O modules
is available at
Verify that a safety administrator conducts a risk assessment on the machine and
determines module suitability before installation.
TIP
Field power must be applied to the 1734-IE4S module when updating
firmware.
ATTENTION: Personnel responsible for the application of safety-related
programmable electronic systems (PES) shall be aware of the safety
requirements in the application of the system and shall be trained in using the
system.
ATTENTION: Use only appropriate components or devices complying with
relevant safety standards corresponding to the required safety category and
safety integrity level.
• Conformity to requirements of the safety category and safety integrity level
must be determined for the entire system.
• We recommend you consult a certification body regarding assessment of
conformity to the required safety integrity level or safety category.
You are responsible for confirming compliance with the applicable standards for
the entire system.
