RELAY BOARD AND AUTOTRANSFORMERS
• Relay Board is complete
• Using jumper wire to bypass 2 connectors for ease of testing, will incorporate
in final testing.
• Autotransformers tested and wired up properly. Ready for use in final test
phase.
• Note: 264 VAC transformer actually outputting 275 at no load. Safe to
assume this will lower when load is applied?
CONTROLLER BOARD TESTING
• Electrical testing complete
• Wire harnesses partially assembled
• Software testing to begin this weekend
• Need to get Bear Supply (12V 36W)
SOFTWARE PROGRESS
• Debug mode ready for hardware testing
• Great debugging tool: Visual Studio w/ Arduino extension
•
Unlike regular Arduino IDE, breakpoints CAN be set and executed while running the Arduino
board
•
Easily watch variables
• Most error codes done
• About half of them are working
• LCD display working
DEBUGGING MODE
• Software code is separated into sections and now can be individually
disabled/enabled, including:
• Procedures
• Loops
• Individual functions
• Other features including an option to print messages to Serial instead of
printing to LCD
•
•
ERROR CODES
•

Error Reasons defined as well
ERROR:
• 24 V NOT FUNCTIONAL
• NO VOLTAGE AT OUTPUT
• CALIBRATION DATA DOES NOT MATCH
• OUTPUT VOLTAGE NOT WITHIN 10% OF 55 V AT NO LOAD
• OUTPUT VOLTAGE NOT WITHIN 10% OF 55 V AT FULL LOAD
• HIGH VOLTAGE AND CURRENT OUTPUT NOT WITHIN TOLERANCE
• 24 VOLTAGE OUTPUT WITH NO LOAD NOT WITHIN TOLERANCE
• 24 VOLTAGE OUTPUT WITH FULL LOAD NOT WITHINT TOLERANCE
• ERROR OR NO REPLY FROM CONTROLLER
• NO SD CARD INSERTED
• SD CARD UNREADBLE
• INVALID BARCODE
• SCAN FAILED – RESCAN
• NO RECORD EXISTS
• RTC FAILURE
• ENCLOSURE OVERHEATED
• CLOSE LID FOR TEST
• WARNING WARNING EMERGENCY STOP
RS-232 TESTING
•
Tested Converter

•
•
Connected to terminal
Receiving & sending commands
PLANNED TO PERFORM ITEMS BELOW
Sent simple commands to controller board
• Unlock code
• Voltage & current settings
• Enable & disable commands
•
Ensured commands are measuring correct output
IMAGINE RIT PROGRESS
• Poster Progress
• Reformatted and cleaned up
• Waiting on finished product picture and testing
results to finish – 80% done
• Paper Progress
• Paper about 80% complete
•
