1. FEC Power Supplies Control and Monitor

This zone contains the controls that allow turning ON and OFF the FEC power supplies, and arrays of rectangular lights that indicate their status.

Visible parameters when all Power Supplies are OFF:

• status (ON/OFF),
• error flags from the power supplies (ERR: OK/NOT OK),
• temperature at the power supply (TEMP: OK/NOT OK),
• communication status (On Time: OK/NOT OK), which will be OK if the last readout took place less than a minute ago. This is sometimes NOT OK for a few seconds while the computer is busy reading out other parts of the system.

To Control the Power Supplies:

• Select which power supply to control, using the menu. One of the options is "ALL", for operating all power supplies at once.
• Turn ON or OFF, pressing the respective button.
• After a few seconds the status light of the power supply will change to indicate the new status.

To Monitor Power Supplies when ON:

The indicators will show if the voltages, currents and fan speeds are within range, for each power supply that is ON.
