:Stores liquid nitrogen up to 40 litters.
:The cold head works in conjunction with the
compressor to generate ultra-low temperature. The
cold head needs maintenance services according to the
time in operation.
:Displays the pressure inside the Dewar.
:Displays the helium pressure of the SW115.
:Use this port when charging helium gas. Do not use
except when needed as it may result in helium leak.
:Use this lever to turn ON and OFF the SW115.
Always keep the lever ON (pressed to the upper side).
This switch can be used as the reset switch when the
SW115 is in error state.
:Displays the total operation time of the SW115. Use
this information to perform maintenance work
properly.
Use this to switch between REMOTE or LOCAL
operation of SW115. When REMOTE is selected,
turning ON and OFF the SW115 is done from the
control circuit of the EMP-14W. When LOCAL is
selected, the SW115 is turned ON and OFF with the
SW115 <RUN/STOP> button. Normally, set this
switch to REMOTE. If switched to LOCAL,
EMP-14W cannot control the SW115.
