Notes
(1) If the module is normal, RDY LED is On.
(2) If 2 or more errors occur, the module will save the first error code generated, and the displayed error will be first
deleted to let the next error deleted.
(3) In case of serious error which makes RDY LED blinks every 0.2 sec., let power OFF -> ON to delete the error.
(4) In case of slight error which makes RDY LED blinks every 1 sec., the error can be deleted without power OFF ->
ON and the module can keep operating.
(5) In case of slight error which makes RDY LED blinks every 1 sec, the parameter value causing the applicable error
is not set on the module, with the existing parameter value kept as it is.
