Switch

Effect

Emergency

Emergency Shut-
down

Electric power of the entire MR system
is switched off, but magnet remains at
field

E.g. in case of fire

Table Stop

Motorized table movement is stopped

In case of accidents or injury due to
table movement

In case of emergency, the relevant switch should be pressed.

(1) Magnet Stop switch

(2) Emergency Shut-down switch

(3) Table Stop button

The Magnet Stop switch triggers a controlled magnet quench
(shutting down the magnetic field). The MR system is not
disconnected from the power.

There are two different versions of the Magnet Stop switch on the
MR system: as an individual switch or as an integral part of the alarm
box. The switches may also be installed in other places of the MR
system.
