Introduction to the Quaternary Pump
The Main Power Supply Assembly
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 quaternary pump fails). To reset the main power
supply to normal operating conditions, turn the quaternary pump off, wait
until it is approximately at ambient temperature and turn the quaternary
pump on again.
The following table gives the specifications of the main power supply.
