Do not perform any operations on any AMI equipment with the cover removed unless qualified to do so and another person qualified in first aid and CPR is present. - Page 6 Do not return the instrument to AMI unless prior authorization has been received. 2. Install the Model 410 programmer on a flat secure surface or install the Model 411, 412 programmer in a 19 inch rack by securing the front panel to the cabinet rails with mounting hardware supplied by the cabinet manufacturer.

Page 13: Description Of Operation
programmer may be operated on 110V ac or 220V ac, 50 or 60 Hz. Instruction for proper wiring (or to change) the input voltage transformer are include in figure 5. The voltage the unit was wired for from the factory is marked on the rear panel. IV. - Page 14 (no current oscillations) under all these conditions is difficult to achieve. The Models 410, 411, and 412 have been designed to achieve this goal. It has been tested with the HP 6260B power supply as well as the Power Ten 10100 switching power supply.

Set the VARIABLE ramp rate potentiometer on 10 and the current control switch in the DOWN position. d. Set the CURRENT LIMIT potentiometer to the rated current as indicated on you AMI magnet data sheet. e. Turn on power to the magnet programmer. - Page 16 voltage/current spikes introduced in the magnet system with could produce undesirable results. k. Reconnect the power leads to the vapor cooled current leads. 2. Mode A (normal mode) operation: a. Place the Computer-Manual switch in the MANUAL position. b. Place to Up-Pause-Down switch in the DOWN position. c.
- Page 17 b. Place the Computer-Manual switch in the COMPUTER position. c. Set the voltage limit potentiometer to 10. d. Energize the programmer and power supply. CAUTION: Always energize the programmer first, then the power supply upon system startup and always deenergize the programmer last on system shutdown to allow the programmer to always have control of the system.
- Page 18 Turn the key operated switch to the OFF position. When the persistence switch heater is turned off you should allow the switch to cool off for approximately 30 seconds. This is a safe number. Actually, most AMI persistent switches cool adequately in a few seconds.
- Page 19 Models 410-412 contains high voltages capable of producing life-threatening electrical shock. Do not perform any operations on any AMI equipment with the cover removed unless qualified to do so and another person qualified in first aid and CPR is present.

- Page 21 28. Connect a precision millivoltmeter across the current shunt. 29. Energize the system as described in the Operation section of this manual. 30. Place the front panel CURRENT LIMIT POT to the fully CW position. 31. Place the front panel CURRENT CONTROL switch in the UP position. 32.
- Page 22 h. Ramp to 100.0 Amps via the MAXUS. i. Adjust GAIN potentiometer P1 until the millivoltmeter reads 100.0 mV. j. Adjust ANALOG OUT potentiometer P4 until the computer via MAXUS reads 100.0 Amps. k. Adjust DVM OUT potentiometer P5 until the programmer front panel current meter reads 100.0 Amps.

Page 23: Troubleshooting
WARNING: If the programmer has been found to been connected to an incorrect power source, return the monitor to AMI for evaluation to determine the extent of the damage. Frequently, damage of this kind is not visible and must be determined using test equipment. - Page 24 4. Current/Voltage Oscillations: a. Oscillations can be caused by a noisy or unstable power supply, misalignment of the programmer, or phase shifts in the system. b. Should any instability occur, the Model 410 is equipped with an adjustable damping circuit. NOTE: Refer to the precautions of the Calibration Section VI.
