5.3.4 DTC digital pcb, version 2
This DTC digital PCB has eight LEDs (CR1 to CR8) on the upper left-hand edge for basic troubleshooting. CR1 through CR6 are
Green; CR7 and CR8 are Red. Their display condition (On, Off, Solid or Blinking) indicates the board state.
CR1: Green, Blinking Blinks when the downloaded code is running.
CR2: Green Indicates method execution in progress.
CR3: Blinking RTC signal is detected.
CR4: Blinking AC Power present.
CR5: Blinking PIC communication present..
CR6: Blinking During Initial Power on
OFF Application code running.
CR7: Blinking T-Rating Error
Blinking (unison CR1) No power to DTC board
CR8: OFF Normal Operation
If the Digital Signal Processor (DSP) system fails during power-up, the LED bank indicates what was being attempted. No green
LEDs (CR1 to CR6) are blinking and CR7 and CR8 are off. CR1 (MSB) through CR6 form a binary code as follows:
