  • Page 5: Warnings [ Refer To This Section Before Operation Of Electromagnet System ]

    Section 2 WARNINGS REFER TO WARNINGS BELOW BEFORE OPERATING ELECTROMAGNET SYSTEM ELECTROMAGNET 1. Safety In operation the magnet fringing field in the vicinity of the pole gap is in excess of 0.5mT (5G). This can cause malfunctioning of sensitive electronic and magnetic components. We recommend that warning signs are posted indicating that a magnetic field may be present.

  • Page 6: Installation

    Section 3 INSTALLATION HARDWARE Mounting Position (Refer to drawing 11902050) The magnet system can be mounting in any orientation, including being completely inverted. The motorized rotating drive can be adjusted for height and also leveled by following the procedure below. Loosen setscrew [item 19] Screw –in/out foot assembly to adjust height and level as required Retighen setcrew [item 19]...

  • Page 7: Electrical Interlocks

    Water Cooling (Refer to drawing 11901960) The Model 5201 can be operated to an average coil temperature of 70° C. Assuming an ambient laboratory temperature of 20°C and a temperature coefficient of resistively for copper of 0.0039/°C, the hot resistance of the coil should not exceed 20% more than the ambient temperature "cold"...

  • Page 8: Software

    Before running the 5201 Magnet Control software set the Com Port control to match the Com Port being used on the control computer. [Com 1 is the default.] The 5201 Magnet power supply is set to GPIB address 2 and is not changeable from the Setup Panel.

    Section 4 OPERATION SOFTWARE DESCRIPTION MAIN CONTROL PANEL Panel Control:. Makes either Setup or Automatic control panels visible. Control Mode:. Selects either Manual or Automatic control mode of operation. Key Focus Control:. When Key Focus is turned on the selected control is controlled by the Up an Down arrows on the computer keyboard.
  • Page 10 Section 4 OPERATION SOFTWARE DESCRIPTION MAGNET ROTATION CONTROL PANEL (Continued) CCW Limit Control: Stops the motorized rotation drive from rotating in thecounterclockwise direction when the current position counter equals the CCW limit setting.[A red indicator shows when limit is reached.] CW Limit Control: Stops the motorized rotation drive from rotating in theclockwise direction when the current position counter equals the CW limit setting.
  • Page 11 Section 4 OPERATION SOFTWARE DESCRIPTION Auto Log Indicator: Flash’s yellow when data is being written to log file. Data to File Indicator: Shows data that will be written to log file. Log File Indicator: Reads the data from the current log file. Log File Name Indicator: Shows the current log file name.

    Select the directory where the open charactization files as located. Select the desired file for the correct height above the magnet. (Note for operation 4.0 mm above the magnet the correct file will be 5201-Z04.olc.) Click the done button (The open loop file charactization sub panel will close).

  • Page 13: Motorized Rotating Drive Operation

    Setup Operation: Firstly power up the Zeta 6104 stepper motor controller. Start the 5201 magnet contol software. Click either the CW or CCW home button. After the platen stops at the approximate zero point reduce the velocity setting to 0.1.

    Section 5 MAINTANCE Electromagnet Electrical Connections on the magnet terminal block should be checked annually. The electrical connections should be clean and tight. Discoloration is a sign that the connection is overheating and must be rectified before further use of the magnet. Water Hoses should be checked regularly for water leaks.
