Watlow PM LEGACY™ Limit Controller • 83 • Chapter 8 Features
Changing PM Model Number to PM Express
PM firmware allows the user to switch between a PM control to a PM Express. Switching to a PM
Express eliminates the complexity of the PM control by allowing the user to operate with a simplified
menu structure.
Note:
When switching from a Full menu control to an Express version, optional PM hardware (even though
installed) and firmware features not available in a PM Express will no longer work. To see exactly
what is impacted by this change, compare the chart below to the ordering information page in this
document.
