Section 6 – SR-2 Service Procedure A46B
Flash Load Recovery
The unit must remain on and connections must not be disturbed during the flash load process.
If the HMI is turned off during a flash load it will lock up. Power will need be to removed from the HMI before the
flash load can be completed. This can be accomplished by removing the connector at the back of the HMI or by
disconnecting the unit battery).
If the power was turned off during flash load, the next flash load attempt will generate an error, but the second
attempt will flash successfully. The failure on the first attempt is 'as designed'. On the second attempt, some of
the error checking between the HMI and Wintrac is bypassed.
