2 blinks = Power Down (after shutdown pulse is sent) 3 blinks = N/A 4 blinks = Over or Under Temperature Condition. (Are you using a fan?) 5 blinks = Power Supply Overload or Fault (ACC must go low to clear a fault) 3.4. Basic Mode Timing Diagram... - Page 7 The connection at location JP1 F1,F2 can be used to provide a signal to an amplifier or auxiliary accessory or slave power supply (like the DSX12V) to come on after the Turn On pulse is sent. This is an open collector output at F1 and F2 is ground.
