It is related to the actual range of pressure
sensor, the corresponding voltage of P18.04
is P05.44.
Note: When restoring to default values, the
value will stay in current value.
0: Invalid
1: Valid
0.00–20.00
When P18.39 is enabled and the auxiliary
pressure is larger than P18.40, the system
indicates auxiliary pressure pre-alarm by
setting BIT7 of P19.14 to 1.
0.00–20.00
When P18.39 is enabled and the auxiliary
pressure is larger than P18.41, the system
alarm indicates pressure alarm by setting BIT9 of
P19.14 to 1, and emergency stop will be
applied.
0: Temperature PID
