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 system operates on 50/60 Hz power and may be configured for 100-115 VAC or 200-230 VAC. The power requirement for each system component is marked on the rear panel of the unit adjacent to the power entry connector. 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.
Installation Bipolar High-Stability Supply retain the data even after power is removed from the instrument. An example of the data to be entered and how it is entered is described in section 3.11 on page 76. 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 Bipolar High-Stability Supply Refer to Figure 2-1 on page 16. 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 interconnection terminals (refer to specifications table on page 9 for torque limits). Overtightening can result in damage to the terminals.

Connect Model 08150PS Master unit terminal block positions CS, S-, and S+ to each corresponding Slave terminal (18). Connect Master to first Slave, first Slave to second Slave, etc. i. Connect two jumpers (17) from terminal block position S- to M- and from S+ to M+ on the Master1 power supply unit. j.
Installation Magnets w/o Persistent Switch 2.6 Special Configurations The Model 430 Programmer has been designed for optimal operation with a superconducting magnet (i.e. a very low resistance, high inductance load) with a persistent switch. The Model 430 Programmer is capable of controlling current to other loads; however, some modification to the Model 430 Programmer settings and/or connections must usually be made.
Installation Power-Up Procedure appears to lag, then decrease the stability setting until the system is responsive. If the current appears to oscillate, increase the stability setting until the oscillations are damped. Note If you have purchased a superconducting magnet with the Model 430 Programmer, AMI will normally provide a recommended stability setting for optimal operation of the magnet system.
Installation Power-Up Procedure 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.1 This will allow rudimentary power supply checks without energizing the superconducting magnet. 3.
Installation Power-Up Procedure 6. Verify the various setup menu values for the system (with the exception of the stability setting, which is to be temporarily left at 100%). If the power supply system was purchased with an AMI magnet, AMI has preset the setup menu values for proper operation. See sections 3.3, 3.5, 3.9 and 3.10 for more discussion of the setup menu values and their entry into the Model 430 Programmer. 7. Set the Model 430 Programmer to display current (rather than field).
Installation Power-Up Procedure Programmer. The current measurement system incorporated in the Model 430 is more accurate than the power supply shunt. 14. Verify that the output current display of the power supply indicates that it is supplying 10 A to the load (which is only the cabling in this case). 15. Set the target current to the master current limit value. Refer to section 3.10.2.4 on page 56 to determine the master current limit value.

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 76. An example ramping operation is presented in section 3.14 on page 89. Note In some of the examples and figures that follow, the ± sign is used to described various controlled parameter values such as current, voltage, ramp rate, etc.
Operation Energizing Power Supply System Components Note If turned off, the Model 430 Programmer must remain unpowered for at least 5 seconds before it is powered back on. If not, there may be an initialization error, in which case the following screen will be displayed. AMI Model 430 Programmer FAILURE TO LOAD. If this occurs, turn the Model 430 Programmer off, wait 15 seconds or more, and power the Model 430 Programmer back on.
Operation Default Display connected to the Model 430 rear panel POWER connector. The current transducer receives this power indirectly via the SIGNAL connection to the rear panel of the Model 430 Programmer. 3.1.2.3 Energy Absorber The Model 601 Energy Absorbers are operational immediately upon connection to a power receptacle.
Operation Default Display : Voltage Programmer display. The parameter displayed (field or current) is toggled by pressing SHIFT followed by FIELD <> CURRENT. Thus, if field strength is being displayed, pressing SHIFT followed by FIELD <> CURRENT will cause the current to be displayed; conversely, if current is being displayed, pressing SHIFT followed by FIELD <> CURRENT will cause the field strength to be displayed. Operating current is always displayed in amperes (A).
Operation Default Display : Status Indicator 3.2.3 Status Indicator Table 3-1. Description of Status Indicators P Paused Ramping Up Ramping Down – Holding The status indicator indicates the Model 430 Programmer operating status. It is always visible (except during a quench condition) and is displayed just to the right of the field / current display (see Figure 3-1). The status indicator may be one of six symbols indicating one of the seven states shown in Table 3-1.
Operation Entering Values Figure 3-2. Numeric Keypad and Associated Keys a prompt for the next digit or decimal entry, and the display will show an asterisk (*) indicating that numeric entry is active. 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.
Operation Fine Adjust Knob Operation 3.4 Using Fine Adjust Knob to Adjust Numeric Values For menu items requiring entry of a numeric value, the value may alternatively be adjusted with the front panel fine adjust knob. These menu items include: • Target Field Setpoint (in holding mode or while ramping) • Voltage Limit • Ramp Rate (if there is no PSwitch or if PSwitch is fully heated). Disallowed during switch heating/cooling transition.
Operation Entering Picklist Values Note The fine adjust knob is velocity-sensitive, meaning that the faster the knob is turned, the more coarse the adjustment. Slow manipulation of the knob will yield very fine resolution even beyond that displayed by the Model 430 Programmer. When the desired numeric value has been set using the fine adjust knob, the ENTER key is pressed to store the value.
Operation Single-key Commands selector will move to the last picklist value. An example of a picklist entry in progress (picklist entry active) is illustrated below: +50.00 A +0.50 Vs Field Units* Kilogauss Tesla When the item selector is pointing at the desired picklist value, press the ENTER key to accept the picklist 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 Single-key Commands : Persistent Switch Control switch was cooled at the rate set by the PSw P/S Ramp Rate variable and then the persistent switch heater is energized. Pressing SHIFT followed by the PERSIST. SWITCH CONTROL key toggles the Model 430 Programmer persistent switch heater between energized (turned on) and de-energized (turned off). If the persistent switch heater is energized and this key is pressed, the persistent switch heater is deenergized.
Operation Single-key Commands : Target Field Setpoint seconds within the Load submenu1. The default cooling period of 20 seconds is adequate for the majority of wet persistent switches. Conduction cooled switches typically require longer time to transition from resistive to superconducting. The default cooling gain of 0.0% may be adequate for the majority of wet persistent switches.
Operation Single-key Commands : Ramp / Pause three seconds before reverting to the default display. The value displayed is as follows: •When in driven mode, the present current/field will be displayed. •When in persistent mode, the current/field will be displayed that was flowing in the magnet at the time persistent switch was cooled. +0.25 A P Magnet Current (A) +0.00 Vs +10.00 A 3.6.
Operation Shift Key Commands 3.7 SHIFT-key Commands / Menus Figure 3-5. SHIFT-Key Functions The most commonly used commands and menus (other than ramping controls) are accessed using the SHIFT key followed by a numeric keypad key. Use of the specific SHIFT-key commands and menus is described in sections specific to the functionality of that specific SHIFT-key.
Operation Shift Key Commands : Ramp Rate ramp rate in terms of current as specified in the table on page 9. If the Ramp Segments value1 is greater than 1, then the menu also allows setting of the field or current range for which each ramp rate is to be used. The Model 430 Programmer will ramp at the specified rate if the available compliance of the power supply is sufficient and the Voltage Limit is not exceeded.
Operation Shift Key Commands : Ramp Rate The right arrow key is pressed once to access the segment 1 range display. The numeric and ENTER keys (or fine adjust knob) are used to set the segment 1 current range upper bound to a value of 55. +50.00 A +0.50 Vs Seg.1 Range (A) 0.0 to ±55.0 Pressing the right arrow key accesses the next (second) segment ramp-rate display. The segment 2 ramp rate is set to a value of 0.1. +50.00 A +0.50 Vs Seg.2 Ramp Rate (A/sec) ±0.
Operation Shift Key Commands : Ramp Rate Current Limit if set lower than the Magnet Current Rating); it will be displayed as “±Limit” and cannot be edited. +50.00 A +0.50 Vs Seg.3 Range (A) ±58.0 to ±Limit Now, when current is in the range of 0 to ±55 A, ramping will be controlled at ±0.2 A/s. When current is in the range of ±55 to ±58 A, ramping will be controlled at ±0.1 A/s and when current is greater than ±58 A (up to the limit of 60 A), ramping will be controlled at ±0.05 A/s.
Operation Shift Key Commands : Voltage Limit If the Current Limit is raised above the Magnet Current Rating, it will be ignored and the actual Magnet Current Rating will govern. 3.7.2 Voltage Limit SHIFT-key +50.00 A +0.50 Vs Voltage Limit (V) ±2.000 Use of the VOLTAGE LIMIT SHIFT-key provides a menu for setting the limit for output voltage for the power supply the Model 430 Programmer controls.
Operation Shift Key Commands : Increment Field When a quench detection has occurred, the Model 430 Programmer will respond to no further input until the RESET QUENCH SHIFT-key is used, or until the quench condition is cleared by a remote command. See Refer to section 3.15 on page 90. 3.7.4 Increment Field SHIFT-key The INCR. FIELD SHIFT-key is used to manually increase the field. This is done at the defined ramp rate. When the INCR. FIELD SHIFT-key is used, the current/field begins ramping up.
Operation Shift Key Commands : Field Units 3.7.7 Field Units SHIFT-key +50.00 A +0.50 Vs Field Units Kilogauss Tesla Use of the FIELD UNITS SHIFT-key provides a shortcut to the picklist menu1 for defining whether the field is specified and displayed in units of kilogauss (kG) or tesla (T). The selected option also applies to remote interface commands. The default setting is kilogauss. 3.7.8 Persistent Switch Heater Current SHIFT-key +50.00 A — +0.50 Vs PSwitch Current (mA) 10.0 Use of the P.
Operation Shift Key Commands : Fine Adjust 3.7.12 Fine Adjust SHIFT-key The FINE ADJUST SHIFT-key is used to enable the use of the front panel fine adjust knob to adjust numeric values. See section 3.4 on page 31 for details. 3.7.13 Persist. Switch Control SHIFT-key Refer to section 3.6.1 on page 33. 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.
Operation LED Indicators : Current Leads Energized a record of that event. Therefore the MAGNET IN PERSISTENT MODE LED state will be incorrect (remain OFF) when the Model 430 Programmer power is restored. Caution If the Model 430 Programmer power supply system is powered off and moved from one magnet system to another, the MAGNET IN PERSISTENT MODE LED may not correctly indicate the state of the magnet system until the first time the persistent switch heater is turned off.
Operation Setup Menu : Entering / Exiting 3.9.1 Entering / Exiting Setup Menu To enter the setup menu, simply press the MENU key. When in any of the setup menus, pressing the MENU key will exit the setup menu. The MENU key toggles the Model 430 Programmer in and out of setup mode. Alternately, if the top level setup menu is being displayed, pressing the ESC key exits the setup menu. 3.9.2 Menu Navigation Pressing the MENU key enters the menu structure at the top level.
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 49. 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 29 or the fine adjust knob (section 3.4 on page 31). 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 29 or the fine adjust knob (section 3.4 on page 31). 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 29 or the fine adjust knob (section 3.4 on page 31). 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 29 or the fine adjust knob (section 3.4 on page 31).
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 29 or the fine adjust knob (section 3.4 on page 31).

Take the following precautions whenever the cover of electronic equipment is removed. 1. Disassemble only in a static-free work area. 2. Use a conductive workstation or work area to dissipate static charge. 3.
Service Troubleshooting Hints Warning This procedure is to be performed only when the Model 430 Programmer is completely de-energized by removing the power-cord from the power receptacle. Failure to do so could result in personnel coming in contact with high voltages capable of producing lifethreatening electrical shock. a. Ensure the Model 430 Programmer and all connected components are de-energized by first shutting down the system and then disconnecting the power cord from the power source. b.
Service Troubleshooting Hints 5.2.3 FAILURE TO LOAD message displayed after power-up 1. Power the Model 430 Programmer off using the front panel power switch. 2. Wait at least 15 seconds. 3. Power the Model 430 Programmer on using the front panel switch. 5.2.4 Power supply unstable - magnet voltage oscillates Note If the size of the voltage oscillation is small (approximately 0.1 volt or smaller), see step 1, below. If the voltage oscillation is larger than approximately 0.
Service Troubleshooting Hints 5.2.5 The power supply system will not charge the magnet. 1. Verify system interconnecting wiring. Refer to section 2.5. If the Model 430 Programmer shows “+0.00 A ↑ Status: Ramping” with the supply voltage, Vs, increasing or at the programmed Voltage Limit (as indicated by the reverse video “V” status indicator), there may be a problem with the power supply.
Service Troubleshooting Hints power loop. Loose or oxidized interconnections often exhibit excessive resistances. 5.2.7 Cannot discharge the magnet at the selected ramp rate Note Rapid discharging of the magnet requires either an energy absorbing component or a four-quadrant power supply. If a unipolar supply is used without an energy absorbing component, only the resistance of the power leads is available as a mechanism for discharging the magnet. 1.
Service Troubleshooting Hints 5.2.10 Cannot bring the magnet out of persistent mode. 1. If a PSwitch Error was indicated when the PERSIST. SWITCH CONTROL key was used to turn on the persistent switch heater current, then there is a problem with the wiring to the persistent switch heater. Check the continuity between the persistent switch heater power supply output pins at the rear panel MAGNET STATION CONNECTORS and the connectors on the magnet support stand top plate. Refer to Table A-1 on page 151. 2.
Service Troubleshooting Hints STATION CONNECTORS and the connectors on the magnet support stand top plate. Refer to Table A-1 on page 151. 5.2.13 The system current ramps slowly from zero With the Model 601 Energy Absorber in the system, an initial charging delay will be observed when operating without an inductive load (e.g. a persistent switch is not heated on a connected magnet). 1. To decrease the amount of time delay, increase the ramp rate to 1 A/sec or greater value.
Service Troubleshooting Hints proper current for the installed switch. Excessive currents cause excessive boiloffs. The typical switch requires approximately 45 mA to function correctly. Refer to the documentation provided with the magnet for proper operating current. See Figure 3-13 on page 77. 2. Verify that the protective diodes on the magnet are not turning on. Damaged diodes may short causing current to flow through them whenever magnet current flows and cause excessive heating.
Service Troubleshooting Hints 3. Check your host communications software and make sure it is recognizing the return termination characters from the Model 430 Programmer. The return termination characters are . 4. If the Model 430 Programmer is responding repeatedly with errors, try a device clear command (DCL) or powering the Model 430 Programmer off and then back on. Be sure you are sending valid commands. 5.2.18 Magnet current drifts unacceptably while PSwitch cooling 1.
