Page 7: Warnings [ Refer To This Section Before Operation Of Electromagnet ]
Section 2 WARNINGS REFER TO WARNINGS BELOW BEFORE OPERATING ELECTROMAGNET 1 Personnel Safety In operation the magnet fringing field is in excess of 0.5mT (5G). This can cause malfunctioning of heart pacemakers and other medical implants. We recommend that the fringing field should be mapped and warning signs be placed outside the 0.5mT (5G) contour. -
Page 8: Installation
Section 3 INSTALLATION Caution: This is a heavy system. All movement, lifting and installation of the 3470 Electromagnet must be under the supervision of an experienced person to prevent the possibility of serious injury or damage to the Electromagnet and associated equipment. -

50°C +/3°C. Cooling The Model 3470 can be operated to an average coil temperature of 70°C. Assuming an ambient laboratory temperature of 20°C and a temperature coefficient of resistivity for copper of 0.0039/°C, the hot resistance of the coil should not exceed 20% more than the ambient temperature "cold"... - Page 10 At currents of approximately 3.50A and below the Model 3470 can be operated safely without water cooling. However the coil temperature will vary with the power dissipation. This results in dimensional changes of the magnet yoke and air cooling is not suitable when high field stability is required.

Page 11: Operation
1. Adjust the poles to the desired gap with the poles approximately symmetrical about the center magnet line. 2. Adjust the cooling water flow to about 1 liters/min (0.26 USgpm) for the 3470. For operation at less than maximum power the water flow may be correspondingly reduced. Note that the inlet water temperature will determine the actual flow rate required. -
Page 12: 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.

Page 13: Maintenance
Section 5 MAINTENANCE Periodically check that the poles are clean, properly lubricated and free of grit and dirt, which may cause binding. Be very careful not to damage the relatively soft pole surface since this may degrade the magnetic field uniformity in the gap. Note that the surface treatments used provide good corrosion protection but in order to maintain the inherent mechanical precision of the magnet, heavy build-up of plating materials is deliberately avoided. -
