4. Once the system operation has been checked to be satisfactory, the voltage control may be set
to its maximum value. This will provide enough voltage for stable operation when running at
high current settings.
5.2 Field Control Operation
The necessity to use calibration curves can be avoided by using a field controller to sense the
magnetic field and provide a corresponding power supply control signal through the power supply
programming inputs. Contact GMW for suitable instrumentation and software (Labview)
(sales@gmw.com).
6. MAINTENANCE
Whenever performing maintenance on this magnet all electrical plug socket
disconnects must be disconnected and a plug lockout device used to properly shut down
the electrical system. Refer to the lockout/tagout procedure defined in section 1.3.
6.1 Cooling Circuit
Check the cooling water circuit to ensure the water is clean and free of debris and bacterial growth.
If an in-line water filter is used, ensure that the filter is clean. If this magnet is used in conjunction
with a closed cycle chiller please refer to the chillers' User Manual for details specific to that chiller
for cleaning and maintenance.
For closed loop water chilling systems we recommend treating the water for algae and corrosion as
required, but no less than every six months. Thermo Fisher provides a water treatment kit, part
number 610000000005, which consists of a corrosion & scale inhibitor, and a biocide. This kit will
treat 10 gallons of water, and multiple kits may be required depending on the cooling system
capacity. Further information regarding water treatment can be found at the end of the 'Technical
Reference' section of this manual.
6.2 Electrical Connections
Ensure that all electrical connections are tight. Check that the cable insulation is undamaged and
that the cable assembly is properly strain relieved. Ensure that all electrical terminal covers are in
place and are firmly secured.
6.3 Interlock Testing
Interlock functions should be verified no less than every three months. Use the procedure described
in Section 4 - 'Interlock Testing' to test the interlock functions.
