Remove any plastic covers from the connector locations on the back of the compressor, the cryostat,
the system control unit, and the vacuum control unit.
1.
User Interface:
Locate the USB and HDMI cables. Connect these cables from the back of the system control unit to the
user interface touchscreen display.
2.
LAN:
Locate the LAN cable (if applicable). Connect LAN cables from the back of the system control unit to
dedicated facility LAN socket.
3.
Compressor Communication:
Locate the DSUB9 M-M series cable. Connect one end to the DSUB9 location on the back of the
compressor. Connect the other end to the COMM PORT location on the back of the system control unit.
Tighten both connections with the thumbscrews to secure.
4.
Control Cables:
Locate the DSUB37 F
–
split cable. Connect the DSUB37 F end to the
HEATER/THERMOMETER CONTROL
location on the TCM peripheral card in the system control unit. Where the cable splits, attach the
DSUB25 F end to the
SAMPLE CONTROL
location, the DSUB25 M end to the
CORE CONTROL
location, and
the MDR26 to the
USER INPUT
locations on the back panel of the cryostat. Tighten connections with
the thumbscrews to secure.
Locate the DSUB25 M-M series cable. Connect one end to the
VACUUM CONTROL
location on the back of
the vacuum control unit. Connect the other end to the
VACUUM CONTROL
location on the ACM
peripheral card in the system control unit.
5.
Helium Hoses:
Helium hoses should first be tightened by hand. Use a crescent wrench to continue to tighten the
fitting, stopping as soon as force is required. Do not overtighten.
•
Locate the helium hose labeled
SUPPLY
. Connect one end to the
SUPPLY
location on the front of the
compressor. Connect the other end to the
SUPPLY
location on the back panel of the cryostat.
•
Locate the helium hose labeled
RETURN
. Connect one end to the
RETURN
location on the front of the
compressor. Connect the other end to the
RETURN
location on the back panel of the cryostat.
6.
Vacuum Hose:
Locate the vacuum hose. Connect one end to the
VACUUM LINE
location on the back of the vacuum
control unit. Connect the other end to the
VACUUM LINE
location on the back panel of the cryostat. The
O-ring seal only needs to be compressed, so take care not to overtighten.
7.
Nitrogen (optional):
To keep the sample space clean, a dry clean nitrogen connection is highly recommended, especially in
humid climates. Nitrogen will help rid the system of moisture and decrease the initial pump down time.
•
Connect a ¼ in (6mm) tube to your nitrogen source (this tubing is not supplied).
•
Start the nitrogen supply at a low flow rate.
•
Verify that the nitrogen is flowing through the tube and does not contain any water vapor. Allow
some nitrogen to flow through the tube to remove impurities.
•
Connect this tube to the
N2 INLET
fitting on the back of the vacuum control unit by pressing in.
•
Set the nitrogen pressure to approximately 15 psi.
