Troubleshooting Failure Code Untuk Doosan Excavator

Sahabat teknisi, untuk posting kali ini saya akan coba share sedikit kepada rekan-rekan mengenai failure code yang ada pada unit merek Doosan atau yang dahulu kita kenal dengan nama Daewoo. Saya mengambil merek Doosan karena saya lihat sekarang ini merek ini sudah banyak mewabah di kalangan usaha alat berat. 

Berikut ini merupakan beberapa failure code untuk unit Doosan S500-LC.

Code	Contents	Cause	Operation	Reset Procedure
82	Communication Err!!	Communication error between e-EPOS controller and instrument panel	* Note	Automatic reset when problem is corrected
01	EPPR v/v short	Short Circuit	Cut off output current (0 mA)	After correcting problem, turn start switch
02	Press Up s/v short	Short Circuit
03	Swing pri. s/v short	Short Circuit
11	EPPR v/v open	Open Circuit		Automatic reset when problem is corrected
12	Press Up s/v open	Open Circuit
13	Swing pri. s/v open	Open Circuit
21	Dial Voltage Err (H)	Output voltage Over 4.6±0.2 V
22	Dial Voltage Err (L)	Output voltage Over 0.4±0.2 V
23	TPS Voltage Err (H)	Output voltage Over 4.6±0.2 V	Cut off EPPR v/v current (0 mA)
24	TPS Voltage Err (L)	Output voltage Over 0.4±0.2 V	Cut off EPPR v/ v current (0 mA)
25	Fpump Sensor Err (H)	Output voltage Over 4.6±0.2 V
26	Fpump Sensor Err (L)	Output voltage Over 0.4±0.2 V
27	Rpump Sensor Err (H)	Output voltage Over 4.6±0.2 V
28	Rpump Sensor Err (L)	Output voltage Over 0.4±0.2 V
29	Speed Sensor Err	Under 1067±20Hz (On condition that alternator output exceeds over 12±1V)
31	Fuel shot to GND	Sensor’s resistance between two terminals is under 150±100W
32	Fuel Sensor open	Sensor’s resistance between two terminals is under 6.5±0.5 kW
33	Alternator too high	Output voltage of alternator exceeds 33 V for more than 3 seconds
34	Alternator too low	When the output voltage is maintained under 18±1 for more than 3 seconds (On condition that speed sensor output exceeds over 1,067Hz)

Note:

1.  If a communication error is generated during operation, the power mode, work mode and auto idle mode will be maintained at the last mode setting before the failure took place until the unit is shutdown.

2. When start switch is turned to the "ON" position during a period of a communication error, the e-EPOS controller will operate in the following modes.

• Power mode: Standard mode

• Work mode: Digging mode

• Auto idle: "ON"(Selection state)

3. The above mentioned two statuses are applicable to normal condition of an e-EPOS controller.

       4. Under the abnormal condition of an e-EPOS controller, communication cable or instrument panel failure,
           "Failure code: 82" can be generated.
