Introduction to the Detector 6

No accessible hardware fuse is needed because the main power supply is safe

against any short circuits or overload conditions on the output lines. When

overload conditions occur, the power supply turns off all output voltages.

Turning the line power off and on again resets the power supply to normal

operation if the cause of the overload condition has been removed.

An over-temperature sensor in the main power supply is used to turn off

output voltages if the temperature exceeds the acceptable limit (for example, if

the cooling fan of the instrument fails). To reset the main power supply to

normal operating conditions, turn the instrument off, wait until it is

approximately at ambient temperature and turn the instrument on again.

The following table gives the specifications of the main power supply.
