Operation

Figure 5.10: Magnet quench indicators on the BCFC front panel
• The green indicator (1, "ARMED") is active
while the "MAGNET QUENCH" button is in
stand by mode. It should always be active
("ON"), otherwise the magnet quench safety
functionality is not available.
• The red indicator (2, "TRIGGERED") is
active when the "MAGNET QUENCH"
button has been pushed and the magnet is
going to quench.
• The red indicator (3, "AC INPUT POWER
FAILURE") displays whether AC power is
supplied to the BCFC. As it has an internal
UPS, it will keep on working for some
residual time. After this time, the BCFC is
completely inactive! Restore AC power
quickly!
• The yellow indicator (4, "REPLACE
BATTERY") lights up if the battery of the
UPS needs to be replaced (every 4 – 5
years).
NOTICE
Use the "MAGNET QUENCH" button only in case of emergency. It is a safety
element that is optimized for quick reaction time. The magnet system may get
damaged from this action.
