7.4 Operation
Once an MSR300 System is correctly set up, it starts and operates automatically in
accordance with the settings done: it needs no operator attention or action during its
normal operation
7.5 Maintenance
An MSR300 System that is correctly configured, set up and installed is inherently
maintenance-free.
Do not attempt to open the housing or repair any of the
modules:
• It is forbidden for safety control products such as this to be
repaired or modified in any way: this can diminish or render
inoperative its critical safety functions.
• Opening the enclosure of a module will immediately void its
warranty.
Defective or damaged modules must be immediately
removed to prevent unintentional usage, and replaced
before attempting to operate the machinery under the
control of this safety system.
It is recommended that the integrity of all electrical connections
(tightness of terminal screws, firm seating of the plug-in terminal
blocks) be inspected at planned intervals.
System checking:
Input devices (safety sensors) and output devices (e.g.
contactors) should be inspected and tested at planned intervals
to confirm they are in good operating condition.
The complete safety system should be inspected and tested at
planned intervals, to confirm that all safety functions are
operating correctly, e.g., by activating the safety sensors under
safe conditions.
Inspection and test schedules depend on operating and site
conditions, and on the user's operations and maintenance
policies.
Test intervals for SIL3 applications depend on system and input
configuration: e.g. worst case scenario: full configuration with 20
single channel inputs and 6 output modules should be tested at
approx. 4.38 month
