Persistent switch operation (flow diagram). General Precautions Cryogen Safety The two most common cryogenic liquids used in superconducting magnet systems are nitrogen and helium. Both of these cryogens are extremely cold at atmospheric pressure (−321°F and −452°F, respectively).
Foreword General Precautions In the event a person is burned by a cryogen or material cooled to cryogenic temperatures, the following first aid treatment should be given pending the arrival and treatment of a physician or other medical care worker: 1. If any cryogenic liquid contacts the skin or eyes, immediately flush the affected area gently with tepid water (102°F − 105°F, 38.9°C − 40.5°C) and then apply cold compresses. 2. Do not apply heat. Loosen any clothing that may restrict circulation.
Foreword Safety Summary is 18-8 stainless steel. Copper, Monel®, brass and aluminum are also considered satisfactory materials for cryogenic service. Magnet Quenches When an energized superconducting magnet transitions from superconducting state to normal state, the magnet converts magnetic energy to thermal energy thereby rapidly converting the liquid helium to a vapor.

2 Installation Warning Before energizing the equipment, the earth ground of the power receptacle must be verified to be at earth potential and able to carry the rated current of the power circuit. Using extension cords should be avoided; however, if one must be used, ensure the ground conductor is intact and capable of carrying the rated current.
Installation Power Requirements 2.3 Power Requirements Warning The power requirement for each system component is marked on the rear panel of the unit adjacent to the power entry connectors. Be sure the power supply system is configured for the proper power source prior to plugging in the line cords. Do not fail to connect the input ground terminal securely to an external earth ground. Ensure the front panel power switches are in the OFF (O) position.
Installation High-Current Four-Quadrant Supply example of the data to be entered and how it is entered is described in section 3.11 on page 72. If the Model 430 Programmer was purchased as part of a magnet system, essential data will have already been entered at the AMI factory and a configuration sheet will have been provided detailing the settings. 2.

Installation High-Current Four-Quadrant Supply Refer to Figure 2-1 on page 14. Ensure the cabling is connected in the following manner: Note The use of locking hardware is recommended for all high-current connections. Caution Do not overtighten the hardware on the interconnections (refer to specifications table on page 8 for torque limits). Overtightening can result in damage to the terminals. Note The current-direction arrow on the CT must point toward the power supply end of the cable. a.
Installation Magnets w/o Persistent Switch i. Optional: Install an instrumentation cable between one of the LHe / TEMP connectors (10) on the rear of the Model 430 Programmer and the Model 13x Liquid Helium Level Instrument and/or temperature instrument (9). Refer to section A.6.2 on page 151. j.
Installation Operation on a Short-Circuit 2.8 Short-Circuit or Resistive Load If operating with a short-circuit as a load without the presence of a superconducting magnet, the Model 430 Programmer must be manually configured for stability. Normally, when the persistent switch heater is deactivated, the Model 430 Programmer sees essentially a short-circuit load since the persistent switch shunts all current flow away from any connected magnet.
Installation Power-Up Procedure doubt as to the correct connection of a component, contact an AMI Technical Support Representative. The user may be required to properly make a few connections between the various system components which were disconnected to facilitate packing and shipping. 2. Temporarily place a short across the magnet current terminals. Often this is most easily accomplished by unfastening the heavy cables from the magnet current leads and fastening them together.
Installation Power-Up Procedure 7. Set the Model 430 Programmer to display current (rather than field). Refer to sections 3.2.1 and 3.7.5. 8. Set the ramp rate to 1 A/sec. Refer to sections 3.3 on page 25 and 3.7.1 on page 33. 9. Set the target current to 10 A. Refer to sections 3.3 on page 25 and 3.6.2 on page 31. 10. If a Persistent Switch is installed, set the PSw P/S Ramp Rate to 10 A/sec. Refer to paragraph 3.10.2.11 on page 56 11.
Installation Power-Up Procedure 19. Turn off the power supply. 20. Reset the stability setting and ramp rate of the Model 430 Programmer to an appropriate value for the magnet to be operated. Then turn off the Model 430. 21. Remove the short from the power supply leads and connect the leads to the magnet current leads of the magnet. After successful completion of this test, the system is ready for operation with a superconducting magnet. Refer to the ramping function example presented in section 3.
3 Operation This section describes the operation of the Model 430 Programmer. Every menu and submenu item is illustrated and described in detail. An example setup of the Model 430 Programmer is presented in section 3.11 on page 72. An example ramping operation is presented in section 3.14 on page 85. 3.1 System Power On/Off Sequence The Model 430 Programmer should always be energized before the power supply that it is controlling.
Operation Energizing Power Supply System Components If this occurs, turn the Model 430 Programmer off, wait 15 seconds or more, and power the Model 430 Programmer back on. When powering the system off, first turn off the power supply controlled by the Model 430 Programmer followed by the Model 430 Programmer. The controller will then ensure the load sees no abnormal power transients as the power supply is turning off. 3.1.
Operation Default Display 3.2 Model 430 Programmer Default Display The default display is illustrated in the figure below. It is displayed whenever no menus are being accessed and no errors are being indicated. The default display can be thought of as being logically divided into four display areas — the Field / Current Display area, the Voltage Display area, the Status Indicator area and the Main Display area. Default display showing ramp mode and persistent switch heater status: +50.00 A — +0.
Operation Default Display : Voltage Note Note that the displayed field strength is not directly measured, but rather is calculated by multiplying the coil constant entered in the setup menu by the measured current flow of the Model 430 power supply system. 3.2.2 Voltage Display The voltage display indicates either the voltage across the magnet (Vm) or the power supply output voltage (Vs).
Operation Default Display : Main meaning of the ramping modes (Paused, Ramping Up, Ramping Down and Holding). 3.2.4 Main Display The default main display (the rightmost portion of the display – see Figure 3-1) shows either a voltmeter indicating magnet voltage or ramp mode and persistent switch heater state. Ramp mode is displayed on the top line of the main display; it will be one of eight states, as shown in Table 3-6 on page 76.

An example of a numeric entry in progress (numeric entry active) is illustrated below: +50.00 A +0.50 Vs Target Current (A)* +74_ Once the numeric value has been entered, press the ENTER key to accept the numeric value. Values are not applied to the operation of the Model 430 Programmer until the ENTER key is pressed and the asterisk disappears from the display.
Operation Entering Picklist Values • PSw P/S Ramp Rate if PSwitch is fully cooled. Disallowed during switch heating/cooling transition. • PSwitch Current • PSwitch Heated Time • PSwitch Cooled Time • PSwitch Cooling Gain • Quench Rate Instead of entering a value using the numeric keypad, SHIFT is pressed, followed by FINE ADJUST. The display will show an up/down arrow ( ) indicating that the fine adjust knob is active. When the fine adjust knob is live, adjustments made using it take place immediately.
Operation Single-key Commands Figure 3-3. Menu Navigation Keys key; the display will show an asterisk (*) indicating that picklist entry is active. While picklist entry is active, the left and right keypad arrows (to the left and right of the MENU key) move the item selector between the different picklist values. Pressing the left keypad arrow moves the item selector one picklist value to the left and pressing the right keypad arrow moves the item selector one picklist value to the right.
Operation Single-key Commands : Persistent Switch Control Figure 3-4. Single Input Keys 3.6.1 Persistent Switch Control Key Pressing the PERSIST. SWITCH CONTROL key toggles the Model 430 Programmer persistent switch heater control function. If the persistent switch heater is energized and this key is pressed, the persistent switch heater is de-energized.
Operation Single-key Commands : Persistent Switch Control persistent switch is installed in the Load submenu and specifying the switch heating current, heated time, and cooled time1. The nominal switch heating current is listed on the magnet specification sheet, and may be entered in the Model 430 Programmer by accessing the Load submenu2. In addition to the heating current, the user must also specify a heated time, cooled time, PSw P/S Ramp Rate and cooling gain.
Operation Single-key Commands : Target Field Setpoint 3.6.2 Target Field Setpoint Key +50.00 A +0.50 Vs Target Field (kG) +50.000 Pressing the TARGET FIELD SETPOINT key provides a menu for setting the target field/current. The target field/current is the field or current to which the Model 430 Programmer ramps the superconducting magnet when it is not paused.
Operation Shift Key Commands Note If the RAMP TO ZERO function is PAUSED and then the RAMP / PAUSE button is pressed a second time, the Model 430 Programmer will begin ramping to the target field, not to zero. If it is desired to ramp to zero after the RAMP / PAUSE button is pressed, press the RAMP TO ZERO button again to continue ramping to zero from the paused state.
Operation Shift Key Commands : Ramp Rate menu, for example, press the SHIFT key, and then press the VOLTAGE LIMIT key (also the 2 key). Note that some of the SHIFT-key menus can also be accessed using the setup menu. Pressing the ESC key or the SHIFT key a second time will clear the SHIFT function and return the keypad to it's numeric function. 3.7.1 Ramp Rate SHIFT-key Use of the RAMP RATE SHIFT-key provides a menu for setting ramp rate(s).
Operation Shift Key Commands : Ramp Rate is installed), attempting to use the fine adjust knob for PSw P/S ramp rate will produce one beep1. Pressing SHIFT and then RAMP RATE will access the ramp rate menu. The numeric and ENTER keys (or the fine adjust knob) are used to set the segment 1 ramp rate to a value of 0.2. +50.00 A +0.50 Vs Seg.1 Ramp Rate (A/sec) ±0.2000 The right arrow key is pressed once to access the segment 1 range display.
Operation Shift Key Commands : Ramp Rate Pressing the right arrow key accesses the next (third) segment ramp rate display. The segment 3 ramp rate is set to a value of 0.05. +50.00 A +0.50 Vs Seg.3 Ramp Rate (A/sec) ±0.0500 Pressing the right arrow key accesses the segment 3 current range display.
Operation Shift Key Commands : Voltage Limit the new “limit” falls within the range of segment 2. The display for segment 2 range will now appear as follows1. +50.00 A +0.50 Vs Seg.2 Range (A) ±55.0 to ±Limit The unused segment(s) will remain in memory (retaining their original parameters) until one or more become active again as the Current Limit is raised into or above the respective ranges. When displayed, the higher-range unused segments will show a range of “±Limit to ±Limit” until re-activated2.
Operation Shift Key Commands : Reset Quench If Voltage Limit becomes active while ramping, it will be indicated by a reverse illumination character “V” for the status indicator. +40.92 A +2.50 Vs V Mode: Ramping PSwitch: ON Once the Voltage Limit function becomes active, the current, and therefore field, will no longer be ramping linearly with time as the voltage available to charge the magnet will be reduced as the total loop voltage will be limited.
Operation Shift Key Commands : Field <> Current 3.7.5 Field <> Current SHIFT-key The FIELD <> CURRENT SHIFT-key is used to toggle between the use of field units, either kG (kilogauss) or T (tesla), and the use of current units (A)1. If the Model 430 Programmer is using field units (either kG or T) and the FIELD <> CURRENT SHIFT-key is used, the Model 430 Programmer will begin using current units (A).
Operation Shift Key Commands : Persistent Switch Heater Current 3.7.8 Persistent Switch Heater Current SHIFT-key +50.00 A — +0.50 Vs PSwitch Current (mA) 10.0 Use of the P. SWITCH HTR. CUR. SHIFT-key provides a shortcut to the menu1 for setting persistent switch heater current. The value can be set to between 0.0 and 125.0 mA. The default value is 10.0 mA unless preset by AMI to match a specific superconducting magnet. 3.7.9 Stability SHIFT-key Use of the STAB.
Operation LED Indicators 3.8 LED Indicators The Model 430 Programmer has six front panel LED indicators. See figure with Table 1-1 on page 5 for the location of these indicators. 3.8.1 Power-on Indicator The green power-on LED indicates that the Model 430 Programmer is powered on. 3.8.2 Magnet Status Indicators Four LEDs are grouped together to show the magnet status. Figure 3-6. Magnet Status LED Indicators. 3.8.2.
Operation LED Indicators : Current Leads Energized magnet system until the first time the persistent switch heater is turned off. Also, should the magnet quench while the magnet is in persistent mode and the Model 430 Programmer is off, the persistent mode indicator LED will be incorrect when the Model 430 Programmer is turned on again.
Operation Setup Menu : Navigation 3.9.2 Menu Navigation Pressing the MENU key enters the menu structure at the top level. The display will look approximately as shown below: +0.00 A +0.50 Vs Setup Mode (Select one) Supply Load Misc The item selector ( ) points to whichever submenu was last used. The left and right arrows at the ends of the displayed submenu selections indicate that there are other submenu selections off screen, to the left and/or right of the submenu selections shown.
Operation Setup Submenu : Supply user will be able to edit parameters under that submenu. See setup menu structure in Figure 3-7 below.
Operation Setup Menu : Supply If using a standard power supply supported by AMI, selecting a power supply within the Select Supply picklist sets all the remaining parameters in the supply submenu per Table 3-2 on page 45. Note The Supply submenu is unique in that it has only the Select Supply picklist as a sublevel (unless Custom is chosen from the picklist of Select Supply options).
Operation Setup Menu : Supply Table 3-2. Select Supply picklist values and associated parameters. Power Supply AMI 08150PS Min Output Voltage (V) Max Output Voltage (V) Min Output Current (A) Max Output Current (A) V-V Mode Input Range (V) 0 +8.000 +0.0000 +150.000 +0.000 to +10.000 +0.000 +12.000 +0.000 AMI 12100PS +100.000 AMI 12200PS +0.000 to +10.000 +200.000 AMI 4Q05100PS −5.000 +5.000 -6.000 +6.000 AMI 4Q06125PS AMI 4Q06250PS AMI 4Q12125PS -12.000 +12.000 −100.000 +100.
Operation Setup Menu : Supply the keypress. Power supply selection should also preferably be performed with the power supply off for maximum safety. The power supply settings define the output voltage and current ranges for a specific power supply. For example, V-I diagrams are presented in Figure 3-8 for the AMI 12100PS and AMI 4Q06125PS selections. The AMI 12100PS operates as a one-quadrant system without the addition of an energy absorber.
Operation Setup Menu : Supply 3.10.1.1.1.1 Min Output Voltage +0.00 A — +0.00 Vs Min Output Voltage (V) -6.000 The minimum output voltage is specified in volts (V) and reflects the minimum output voltage compliance of a connected power supply. The valid range is 0.000 to -20.000 V, and can be set by using either the numeric keypad per section 3.3 on page 25 or the fine adjust knob (section 3.4 on page 26). A unipolar power supply has a minimum output voltage of 0.000 V. 3.10.1.1.1.
Operation Setup Submenu : Load 3.10.1.1.1.4 Max Output Current +0.00 A — +0.00 Vs Max Output Current (A) +100.000 The maximum output current is specified in amperes (A) and reflects the maximum output current capacity of a connected power supply. The valid range is 0.001 to +2000.000 A1, and can be set by using either the numeric keypad per section 3.3 on page 25 or the fine adjust knob (section 3.4 on page 26). 3.10.1.1.1.5 V-V Mode Input Range +0.00 A — +0.00 Vs V-V Mode Input Range (V) -10.
Operation Setup Menu : Load by using either the numeric keypad per section 3.3 on page 25 or the fine adjust knob (section 3.4 on page 26). The valid range is from 0.0 to 100.0%. The default value is 0.0% unless preset by AMI to match a specific superconducting magnet.
Operation Setup Menu : Load reason, small changes in Stability Setting have a large effect on stability as the Stability Setting value approaches 100%. Changing the Stability Setting from 99.9% to 99.8% changes the gain multiplier from 0.1% to 0.2% (changing the gain multiplier by a factor of 2, a 100% increase in the gain multiplier). Note, however, that the same 0.1% change in Stability Setting from 90% to 89.9% only changes the gain multiplier from 10% to 10.
Operation Setup Menu : Load performed — all operations will be performed and displayed in terms of amperes. Values from 0.001 to 999.99999 are acceptable for coil constant. The default value is 1.00000 kG/A (or 0.10000 T/A) unless preset by AMI to match a specific superconducting magnet. If the coil constant is not explicitly stated within a superconducting magnet’s specifications, the value can be obtained by dividing the rated field by the rated current. Note that 1 T = 10 kG. 3.10.2.
Operation Setup Menu : Load magnet, and specific magnet data has not been provided by the customer, the Model 430 will ship with Magnet Current Rating set at the default value of 80 A. Figure 3-11 shows the default Magnet Current Rating as set within the 4Q06125PS power supply limits. Figure 3-11. Magnet Current Rating Set Within Supply Range The Magnet Current Rating can be set by using either the numeric keypad per section 3.3 on page 25 or the fine adjust knob (section 3.4 on page 26).
Operation Setup Menu : Load The Current Limit setting can be used to limit the magnet current to values lower than the Magnet Current Rating for testing or other purposes (refer to Figure 3-12). Figure 3-12. Example Current Limit Setup The value can be set by using either the numeric keypad per section 3.3 on page 25 or the fine adjust knob (section 3.4 on page 26).

Operation Setup Menu : Load may be set to any value between 0.1 and 10 A/sec. The value can be set by using either the numeric keypad per section 3.3 on page 25 or the fine adjust knob (section 3.4 on page 26). The default is 10 A/ sec unless preset by AMI to match a specific superconducting magnet system. 3.10.2.12 PSwitch Cooling Gain +0.00 A P PSwitch Cooling Gain (%) +0.00 Vs 0.0 The default cooling gain of 0.0% may be adequate for the majority of wet persistent switches.
Operation Setup Menu : Load 3.10.2.14 Energy Absorber Present +50.00 A — +0.50 Vs Energy Absorber Present? NO YES This picklist value indicates whether an energy absorber, such as the AMI Model 601, is connected to the power supply system. The default setting is NO. It is important for this setting to be correct since the internal gain tables of the Model 430 Programmer compensate for the additional load of the energy absorber if present.
Operation Setup Submenu : Misc 3.10.3 Misc Submenu When the Misc submenu is selected, several miscellaneous parameters may be viewed and/or changed. 3.10.3.1 Display Brightness +50.00 A — +0.50 Vs Display Brightness (%) 25 50 75 100 This picklist value controls display brightness.
