 +|**N.**\\ **flashes**|**Error**|**Description**|**Recommended action**|
 +|  **1**  |**Bus error**|Bus configuration different to application software.|Check the correspondence between the QMOVE application (BUS section of configuration unit) and the product  configurations (cards mounted in BUS).|
 +|  **2**  |**CheckSum Error**|Negative outcome on the integrity control of retentive variables . (see Reset Error Checksum)|Restore the machine data from a backup (.DAT file) or cancel the error with in system functions and enter the values manually.|
 +|  **3**  |**Index Out of Bound**|An array index is pointing on an inexistent element|Open a unit editor in Qview development environment and use the "Edit->Go to PC" command to find the program line that is cause of the error. In general the index value has a value <1 or >array dimension.|
 +|  **4**  |**Program Over Range**|The program selection index in the DATAGROUP has attempted to access an inexistent program.|With the Qview development environment open the editor of a unit and user the "Edit->Go to PC" command to highlight the program line that has caused the error. In general the value used as index is lower than 1 or over the array dimension.|
 +|  **5**  |**Step Over Range**|The step selection index in the DATAGROUP has attempted to access an inexistent step.|With the Qview development environment open the editor of a unit and user the "Edit->Go to PC" command to highlight the program line that has caused the error. In general the value used as index is lower than 1 or over the array dimension.|
 +|  **6**  |**Division By Zero**|The denominator of a division operation of the application program has a zero value.|With the Qview development environment open the editor of a unit and user the "Edit->Go to PC" command to highlight the program line that has caused the error.|
 +|  **7**  |**Syntax Error**|The application program has an invalid instruction|This error may appear because the program counter has met the QCL END instruction.|
 +|  **8**  |**Watch Dog Error**|A CAN module does not function correctly, or a specialist card has a hardware problem|With the Qview development environment open the "Monitor->Bus" panel and the righthand column called "Watchdog Bus" indicates the card that caused the problem.|
 +|  **9**  |**Stack Error**|The applciation program has used all permitted levels of calls to subroutines|With the Qview software environment open the editor of a unit and use the "Edit->Go to PC" command to highlight the program line that caused the error. Analyse the unit execution flow, the call to subroutines nestings have a limit, over which this error is generated.|

 +=== Hardware error codes ===
 +
 +During the startup sequence, if a malfunction of any peripheral is detected, the system blocks and the error is signaled by the flashing led  {{led:led_lamp.jpg?direct&20}}err  while the other system led's remain off.
 +
 +The number of flashes indicates the type of error according to the following table :
 +
 +^Number of flashes^Error^
 +|  1  |Display|
 +|  2  |FPGA|
 +|  3  |Media|
 +|  4  |Bootloader|
 +|  5  |FW|
 +|  6  |Bus|
 +|  7  |//Signal not active//|
 +|  8  |//Signal not active//|
 +|  9  |Exception|
 +.
 +^:important:^Each of these signals indicates a serious error situation. The product must be sent to the QEM aftersales service.^
