Documents provided by Client: 9 Schematics of the power-related segments of Equipment Under Test 9 Client’s Confidentiality Agreement Test environment provided by Client: 9 A test space that provides convenient, safe, comfortable access to the Equipment Under Test 9 Equipment Under Test in operating condition, with gas, cooling, air, and other utilities connected 9 Readily-disconnected electric power for Equipment Under Test, with current limiting devices rated no more than twice the nameplate rating of the Equipment Under Test. Each electric power connection must be clearly labelled with phase identification and voltage. 9 Instrument power (100-240VAC, 50/60 Hz, 5 amps) for sag generator, located no more than three feet from power connection for Equipment Under Test.

Insulating mats were N/A. 9 The following participants had current CPR training: Bob Jones Electric power connections 9 Power was 3-phase, center-grounded delta configuration, 240 V nominal phase-to-phase, 50 Hz. 9 The fused disconnect switch was equipped with 60A fuses, rated for 200kA interruption. 9 Less than 100 kA of short-circuit current was available, so the 200 kA interruption rating on the fuses was deemed adequate. Equipment under test 9 Model 2200, S/N 99SW4502, Stepper/Washer. Client states that this equipment is generic for Series 2200 operating on 240V 50 Hz. Client states that this is a pre-production unit. 9 The schematics of the power-related section of the EUT were reviewed, including the input power connections (p.1-7), current limiting devices, undervoltage/overvoltage/unbalance trip (N/A, except possibly in washer pump), on/off controls (p.12), emergency off controls, transformers, motors (fan, pump motor ), control-related power supplies, power supplies (diagnostic signals on p.22-24), power-related reset circuits, power-related component protective circuits (noise filter, isolation transformer). 9 The SEMI F47 “idle” mode was determined by the client to be the EUT’s standby mode. The SEMI F47 “Most sensitive process state” was determined by the client to be the EUT’s full-powerwash/step mode. After some testing, it was determined that the standby mode was highly insensitive to sags, and testing should be concentrated on the “Most sensitive process state”. Note: The EUT has several power supplies connected single-phase from phase to phase; however, the schematic does not indicate which pair of phases are used. Therefore it is important to check every 4 phase when testing for sags on individual phases -- different units may be wired differently. Equipment under test (continued) 9 The client determined that indications of equipment failure or misoperation criteria included: spin-down; EUT shutdown; fault light(s); or error messages on the CRT. Note: The EUT had a nameplate rating of 60A per phase, and prior to testing the client expected a maximum current draw of 50-55 A per phase under worst-case, intermittent conditions. However, during several tests (Test #12, 14, 25, 37, 39, 46, and 50) the EUT drew more than 70A rms immediately following a voltage sag. The soft-start currentlimiting circuits were apparently disabled once the EUT had completed its power-up cycle, and the filter capacitors in the power supply required all available current for re-charging. Graph 1: The EUT draws more than 125A instantaneous (full scale of the current recording) at the conclusion of a brief voltage sag, well in excess of its 60A rms (equivalent to 85A instantaneous) nameplate rating. Note: In the following table, “HVPS” is an abbreviation for “High Velocity Pressure Sprayer”. 5 Table 1: Sag Immunity Test Results for Model 2200, S/N 99SW4502 Test # 1 2 V1-V2 % nominal 50 70 V2-V3 % nominal 100 100 V3-V1 % nominal 100 100 DUT mode Stndby Stndby Sag duration (cycles) 12 30 Result Pass ? 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 70 80 0 80 90 50 70 80 0 80 80 80 90 45 0 0 0 45 45 45 65 75 0 0 75 85 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 45 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 Stndby Stndby Stndby Stndby Stndby Oper.

Note 1: This point (50% sag for 12 cycles) initially failed for L3-L1 sags with a “High Velocity Pressure Sprayer” fault, but passed for L1-L2 and L2-L3 sags. General observations about the test results 9 For almost all of the required SEMI F47 sags, the EUT passed with substantial margins, as indicated by the green results in areas where the EUT is not required to operate. 9 For all of the recommended SEMI F47 sags, the EUT passed with substantial margins. 9 The 50% sag for 12 cycles on L3-L1 failed. Further investigation is described below. 7 Further investigation of 50% sag, 14 cycles, L3-L1 Graph 2A: Voltage output. 14 cycle sag to 50%. Graph 2B: Current into EUT. Note large current surge at conclusion of sag. Graph 2C: +24V auxiliary supply in High Velocity Pressure Sprayer (HVPS). This supply is labelled as both +24V and +30V at various places on the schematic. It is derived from L3-L1 in the EUT. Graph 2D: Aux Power Supply Fault (logic signal). This signal comes from a comparator that compares a reference voltage to the output of a linear regulator fed by the +24V auxiliary supply. When the input voltage (Graph 2C) drops below the minimum voltage required by the linear regulator, this Fault signal is generated, causing the EUT to shut down. These graphs show a 14-cycle sag generated during Test #57. The EUT shut down due to a High Velocity Pressure Sprayer Fault. Recommendation: increase the energy storage capacity of the 24V auxiliary supply. Conclusion: Re-testing with increased filter capacitor (from 1000uF to 2200 uF) in +24Vdc auxiliary supply in High Velocity Pressure Sprayer demonstrated that the EUT easily passed all of the SEMI F47 requirements. 8 Conclusions 1. IntraTech Model Model 2200, S/N 99SW4502, as modified and tested May 2000, met all of the voltage sag immunity requirements of SEMI F47. 2. IntraTech Model Model 2200, S/N 99SW4502, as modified and tested May 2000, met all of the voltage sag immunity recommendations of SEMI F47. 3. IntraTech Model Model 2200, S/N 99SW4502, as modified and tested May 2000, had reasonable margins beyond the requirements of SEMI F47. 4. Manufacturer states that the tested model is typical of Intratech 2200 Series with 240V 3-phase 50 Hz power. _________________________________ Alex McEachern 14 May, 2000 Power Standards Laboratory http://www.PowerStandards.com 9
