HS3-R & HS3-R/Q SOFTWARE REVISION HISTORY

• V1.0 ORIGINAL VERSION
• V1.01 'Open Rotor' reporting fix
• V1.01 Extend limits to 'Setup' table.
• V1.02 Added exit 'DCBRAKE' and 'ACBRAKE' if High Speed Fluoro
• V1.02 Added High Speed Run FL text
• V1.02 Add fixes for High Speed Fluoro and High Speed Start for displaying correct message and correcting control of the Kaux relay if High Speed Fluoro stays on and then HS Rotation is on. This is an unlikely scenario but is concievable.
• V2.00 Added new programming options for maintaining interlock during shift from low speed to high speed. Added new programming option for 'T1' input. Allows programming for defaulting to Tube 1 (no T1 input required). This keeps compatibility with the HS2 interface and for generators with no 'T1' selection or single tube installations. Manual updated to Rev 2.0
• V2.01 50 Hz fixes:Allow lower minimun measured 'A' (low speed), and expanded min/max tables for setup
• V2.02 Adjusted 50 Hz measurement time for A & P (shifted and principle) measurement. Slight increase in measured values. Dec 22,1998
• V2.10 Automated measurement times for current sampling. This software determines the optimum measurement phase angle for the stator in use. Current measurement issues resolved with this change.
• V2.20 Mandatory Upgrade!! This software fixes a potential problem of leaving the interlock enabled with a processor board malfunction.
• V2.21 Fixed a reset condition if multiple tubes are selected.
• V2.21 Fixed High Speed Fluoro to hold if the 'FL' is just a momentary signal to get the tube spinning. This was doing a high speed start and then going to AC brake.
• V2.22 Fixed Diag14 (Diagnostic14). Inverter had no overlap and was not running at 180 Hz.
• V2.23 Changed the calculation for minimum currents. The minimum current is now the measured current devided by 2. This method provides a lower minimum current for fault.
• V2.30 Widened default Setup tables for stator types. Corrected hold time setting for 0 seconds of hold and minutes (there was no hold if zero seconds but minutes were programmed). If in 'Setup', only allow rotation command from 'Test' button. Automatic selection of 'Setup Select' if the starter has not been 'Setup'. Calculate a minimum DC brake during 'Setup' (3 times the low speed boost time). This calculated amount overides the DC brake setting if the calculated time is longer. Further debounce of switches for steps in 'Setup'.
• V2.40 Mandatory Upgrade!! Added software detection of inverter failure (previous software would not detect the inverter half waving). Four new error messages relating to the inverter test. Service Manual updated to reflect the new error messages. Changed 'Setup' to allow 'non-save exit' at Step 1 (Rotor Type). Increase High Speed 'Shifted' measurement delay for compatibility with Varian housings. Changed the 'Setup' step selection to display the selected value without letting go of the next/previous button (improving visual response to step changes).
• V2.41 Small fix for 'Q' stator Low Speed Maximum 'P' value in 'Setup' tables. The max 'P' value was not increased to the normal adjusted value and is now set to the normal value. The main effect is that with a high line, the 'P' current may be above the old value and generate the error 'P' current too high.
• V2.42 Added fix at power up to overcome reseting due to extremely noisey line.
• V3.00 Added DC Brake test rotation at Step 3 of Setup. Allows testing of the accelerate and DC brake times to determine optimum settings. Added Math test at power up and appropriate failure message. Fix High Speed test rotation when HS signal is programmed to 'Disabled'. This allows a complete High Speed Test rotation even though HS is disabled in programming. Disable 'Test Rotation' during DC brake to ensure that the anode is stopped. Fixed 'Reset' problem when power up self test error message is displayed. Changed hit 'Value +/-' key to 'Value +' key. Added message hold at exit setup and added message for exit setup without save.
• V4.00 Added HI-R Stator Selection for use when the gain circuit is change to accomodate NAI housings (Toshiba).  Fixed a small bug which causes a false start during the first 'Test' rotation in low speed.  Added special debounce routine for the test rotation switch on the front panel.  Prevent going on to the next programming step untill the low speed test rotation has been completed.
• V4.01 Current measurement improvement to prevent environment noise from causing false current readings.
• V4.02 Added line IRQ and Timers test after 1-2-3-4 (improved the self test at power up).
• V4.03 Reset bug fix with high speed coast.  (The starter would intermittently reset while in high speed coast).  Also, fixed LS coast routine to allow for change to High speed while in coast mode.  I.E., if in Low Speed Coast and a High Speed request is initiated then this allows for drop from low speed coast and going to high speed boost.
