Issue:
The ATS48 Fault Reset sent over Modbus.

Product Line:
Altistart 48

Environment:
All models and serial numbers.

Cause:
None

Resolution:
Fault reset is performed when bit 7 of command word 400 transitions from 0 to 1.  Write decimal 128 to register 400.  If there is an offset then write decimal 128 to register 401.  Once the reset has been performed write a decimal 0 to the register to reset bit 7 to 0 to allow transition when the next reset is performed.
