6.2.7 Operating modes
Control boxes can operate in “M” or “P” mode, depending on power cable connection (par.
6.2.8).
• “M” mode of operation:
Section valves are closed or opened from the main switch provided that section valve switches
are set in the appropriate position; in other words, if section switches are set to OFF (lever down),
operating the main switch does not affect the sections. If one or more section valve switches are set
to ON (lever up), opening or closing the main switch opens or closes the section valves as well.
• “P” mode of operation:
section valves are operated independently.
Main switch control functions do not affect section valve opening or closing.
6.2.8 Setting “M” or “P” operation mode
The power cable has an additional wire for operating mode setting (par. 6.2.7).
Operation mode depends on the type of connection:
