Performing a Programming Key Memory Erase
If an application is loaded on the Programming Key, and you want to
use a different application, you have to erase the Programming Key
memory.
The Programming Key memory is erased automatically when you use
FX Loader. However, when an application is loaded from a computer,
or when the application is loaded from another FX15 controller, you
must manually perform erase the Programming Key memory.
To erase the Programming Key memory:
1. Power up the Programming Key, either by hot-plugging it to an
FX15 controller (already on) or with an AC/DC adapter.
2. Press the Programming Key button for 15 seconds to initiate the
memory erase.
During the memory erase, the green Light-Emitting Diode (LED)
blinks slowly. Then the green and the yellow LEDs blink twice
alternately, and then the green LED remains on indicating the
memory is erased.
If the green and the yellow LEDs blink simultaneously, it means that the
erase process has failed. Retry. When the memory is completely erased,
the LEDs stop blinking. The Programming Key is now ready for a new
upload. The memory erase is also necessary if the previous upload from
the FX15 controller fails (communication has been interrupted).
Error Codes
You can view the error codes only when an integrated MUI display
(LP-DIS60U10-C) is mounted to the FX15 controller.
