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.
