Device Over-current Fault<br />

Additional Information<br />
Messages<br />
Make sure the device selection matches the manufacturer and part<br />
number of your device as precisely as possible. If it doesn't, select the<br />
proper characteristics and perform the operation again.<br />
Note: Choosing a wrong manufacturer and/or part number (via the<br />
Select device option from the Main Menu) causes the programmer to<br />
expect an electronic ID different from your device's ID.<br />
Faulty device(s) Load the suspect device (Main Menu/Load). If an overcurrent error<br />
occurs, load new devices. If other devices load with no errors, a single<br />
device may be faulty. If no errors occur during load operation, try to<br />
program another device (Main Menu/Program Device). If other devices<br />
program without error, a single device may be faulty.<br />
If other devices also produce overcurrent errors during load or program<br />
operations, check the date code. If failures occur only on devices with a<br />
particular date code while other parts are programmed or loaded<br />
successfully, the problem is probably device related.<br />
Note: If the problem appears to be device related, you may wish to<br />
notify the device manufacturer.<br />

Programmer hardware<br />
problem<br />
If other devices produce overcurrent errors during load and program<br />
operations, disable the Continuity check parameter displayed on the<br />
Programming Parameters screen (via More/Configure system/Edit/<br />
Programming options from the Main Menu).<br />
If this error occurs during a programming operation but not during a load<br />
operation, a device test may be causing the problem. Disable all device<br />
checks (such as Device check and Illegal bit check) listed on the Program<br />
Device screen by changing the appropriate fields from Y to N. Press the F4<br />
key to display all parameters.<br />
If this error occurs on devices with old and recent date codes, there may<br />
be a software bug in the device's programming algorithm.<br />
Workaround: On the Device List, find an earlier version of programmer<br />
software that supports your device, boot your programmer with this<br />
version, and repeat the operation.<br />
Note: Contact <strong>Data</strong> I/O Customer Support and report your findings.<br />
If an overcurrent error occurs with different devices, a hardware problem<br />
may be indicated. To determine whether a hardware malfunction exists,<br />
perform a self-test (Main Menu/More Commands/Self-test) with no<br />
devices in the socket. If the self-test shows a malfunction, make the<br />
necessary service arrangements.<br />
This error is reported by the hardware overcurrent detection circuitry on the<br />
programmer. The trip level for the overcurrent error is set by the programming<br />
algorithm. From the error alone, it is not possible to determine which operation the<br />
programmer was performing (device tests, program, verify/read) when the<br />
overcurrent condition was detected. To determine the nature of the problem, you<br />
need to isolate the operation that is being performed.<br />
