Cpu Active" Led - Gamatronic Centric 3x480 Vac User Manual

4.2.3

"CPU active" LED

The "CPU active" LED is normally a solid green. If this LED is not lit (a very rare occurrence), the CPU has
stopped operating. Using the "CPU On/Off" button may resolve the problem. See section 4.2.4.
4.2.4 "CPU On/Off" button
Pressing the "CPU On/Off" button switches the UPS's main computer (the CPU) off or on. This is for use
only in the rare instance that the LCD touch screen freezes up or the system otherwise ceases to respond
to commands. In such a case, switching the CPU off and then on again may resolve the problem.
The Centric will continue to operate as normal even when the computer is turned off, although obviously
there will be reduced functionality.
