Preventative Maintenance
Rockwell Automation recognizes that following a defined maintenance schedule
delivers the maximum product availability. By strictly following the maintenance
schedule of tasks that is provided for your operating environment, you can expect
the highest possible uptime. A maintenance schedule is provided for each of these
environments:
• Tab le 3
Recommended Maintenance Schedule for Normal Operation on
page 29
. Normal operation is defined as an environment where the
ambient temperature is less than or equal to 40 °C (104 °F).
• Tab le 4
Recommended Maintenance Schedule for High Temperature
Operation on page 33
. High temperature operation is defined as an
environment where the ambient temperature is above 41 °C (106 °F).
• Tab le 5
Recommended Maintenance Schedule for Harsh Environment
Operation on page 37
. Harsh environment is defined as a copper or silver
reactivity level greater than 1000 angstroms per 30 days exposure. No
condensation allowed. Maximum allowable humidity is 60% in the
presence of corrosive gases. See ISA-71.04-2013 for details on how to
measure reactivity levels on copper and silver test coupons.
