10 <strong>MSC</strong> <strong>II</strong> (<strong>Moog</strong> <strong>Servo</strong> Controller) Power Supply<br />
10.8 Power Supply<br />
DANGER The 24 V power supply terminals of all M3000 ® modules are<br />
protected against reverse polarity.<br />
If the polarity of these power supply terminals is reversed, the<br />
modules will not work.<br />
WARNING M3000 ® modules must be protected from overvoltages<br />
and/or reverse energization from the sensor to the module!<br />
There is a danger of:<br />
• Permanent damage by overheating or fire<br />
• Malfunctions<br />
M3000 ® modules must have the correct voltage, polarity, and<br />
terminal assignments.<br />

10.8.1 Behavior at Switching on and Switching off<br />
The following internal data resides in the flash EEPROM of the <strong>MSC</strong> <strong>II</strong> control<br />
module:<br />
• Boot projects<br />
• Error messages<br />
There is no battery buffered memory area. The <strong>MSC</strong> <strong>II</strong> control module is<br />
maintenance-free.<br />
WARNING If the most recent status in the online mode (MACS<br />
logged in) was 'Run' before the <strong>MSC</strong> <strong>II</strong> control module<br />
was switched off or reset, the boot project will always be<br />
started after the <strong>MSC</strong> <strong>II</strong> control module is switched back<br />
on or reset.<br />
This will occur regardless of which application program was<br />
previously running.<br />
In other words, the application program that will be started<br />
automatically after the <strong>MSC</strong> <strong>II</strong> control module is switched on<br />
or reset might be different from the application program that<br />
was executing immediately prior.<br />
Application programs can be saved and executed in the <strong>MSC</strong> <strong>II</strong> in the following<br />
manner:<br />
• As a boot project in the flash EEPROM<br />
• In RAM<br />
An application program saved as a boot project will be loaded into RAM<br />
whenever the <strong>MSC</strong> <strong>II</strong>'s power supply is switched on or when the <strong>MSC</strong> <strong>II</strong> is reset.<br />
