Herover ses et oscilloskop billede af pulserne p\u00e5 txd p\u00e5 curtis som sendes til displayet og laver en stribe stjerne i bdi 840 display.<\/p>\n

Det er ikke lykkedes at kommunikere med curtis, der skulle v\u00e6re indbygget vendor id i original kommunikationens adaptor. At det er rigtigt kan det faktum at rxd til processorens ben 79 rxd0, g\u00e5r omkring en pic processor og en zilog chip, inden signalet k\u00f8rer hen til en transistor q33 underbygge.<\/p>\n

Det lykkedes dog at f\u00e5 seriele data til bdi ind i en vt100 terminal emulator:<\/p>\n

dette billede viser n\u00e5r curtis k\u00f8rer, og data der ses er 100% opladt, der kan klikkes p\u00e5 menu knap (ben 19) og vises 72 volt , derefter ampere som er 0,1 amp\"curtis_txd_terminal_emulator_mot_open\"<\/a><\/p>\n

billedet herover viser viser n\u00e5r curtis ikke starter op og viser fejlkoder:<\/p>\n

13 og 27<\/p>\n

Ved tydning af fejl koder tages udgangspunkt i manual:<\/strong><\/p>\n

1234\/36\/38 Manual, p\/n 37022<\/em>
\nRev. D: July 2008<\/em>
\n\u00bb Software version OS 11.0 \u00ab<\/em><\/p>\n

Fejl kode 13 betyder:<\/strong><\/p>\n

<\/p>\n

Current Sensor Fault<\/p>\n

1. Leakage to vehicle frame from phase Set: Controller current sensors have
\nShutdownMotor; U, V, or W (short in motor stator). invalid offset reading.
\nShutdownMainContactor; 2. Controller defective. Clear: Cycle KSI.
\nShutdownEMBrake;
\nShutdownThrottle;
\nFullBrake;
\nShutdownPump<\/p>\n

Fejl kode 27 betyder:<\/strong><\/p>\n

Digital Out 7 Overcurrent 1. External load impedance on Digital Set: Digital Output 7 (pin 20) current
\nDigital Output 7 driver Output 7 driver (pin 20) is too low. exceeded 15 mA.
\nwill not turn on. Clear: Remedy the overcurrent cause
\nand use the VCL function Set_DigOut()
\nto turn the driver on again.<\/p>\n

Mot OPEN betyder:<\/strong><\/p>\n

“Mot Open”
