This function will display the errors that are detected by the controller in the attachment parts.
Enter service code 1C. The character display will display "1C t oP" first. Then, the character display will display the error codes. The following procedure is used in order to view the error codes that are present. The error codes are displayed in the right four character positions. The display will show "End"on the character display, if no problems are present.
The fine control mode switch (25) is pressed in order to flash "1C t oP" on and off.
When the boom priority mode switch (23) is depressed, the character display displays the existing error codes in ascending order. When the end of the list is reached, the character display will show "End".
When the swing priority mode switch (24) is depressed, the character display will display the existing error codes in descending order. When the end of the list is reached, the character display will show "A t oP".

Real Time Error Codes (Attachment)    
Code     Description Of The Problem    
4104     overcurrent in digital output (spare solenoid 1).    
4108     overcurrent in digital output (travel alarm.)    
4109     Spare.    
410B     Spare solenoid 2.    
4205     Spare PWM sensor 1 is shorted to frame ground.    
4206     Spare PWM sensor 2 is shorted to frame ground.    
4208     Spare PWM sensor 1 is open in circuit.    
4209     Spare PWM sensor 2 is open in circuit.    Error Log
Enter service code 19. The character display displays "1d t oP". Then, the character display displays the error codes that are stored in the memory of the controller. The following procedure is used to view the stored codes. These error codes are displayed on the right four character positions. An error that is not present is kept in the memory until the error is cleared. The procedure that is used to clear the memory is described later.
The fine control mode switch (25) is pressed to flash "1d t oP" on and off.
When the boom priority mode switch (23) is depressed, the past error codes are displayed in ascending order. When all of the stored error codes have been scanned the display will show "End".
When the swing priority mode switch (24) is depressed, the past error codes are displayed in descending order. When all of the stored error codes have been scanned the display will show "t oP".
In order to clear all of the error codes in the memory, the power mode switch (19) and the travel alarm cancel switch (22) are pressed and held for 2 seconds or more. When the display shows "CLr", the error codes in the memory have been cleared.
Error codes are identical to real time error codes. Note: After the corresponding problem has been corrected, clear the error code. Ensure that the error code is no longer displayed.
