When the FAIL alarm is specified, the output 2 is not output.
FAIL alarm is output from the contact output of alarm 3
(terminal No.51 and 52).

When the alarm 3 is specified as the output 2, output type is
only relay contact output.

For three-phase heater break alarm, special specified code
“Z-168” must be specified at the end of the model code.
Three-phase heater break alarm cannot be specified with
MA901.
6
If the heater break alarm is selected, contact input and
communication function cannot be selected (MA901 only).
