this set temperature，early warn the machine stop.
When the actual air supplying pressure higher than
the set pressure，give stop warning.
In user parameter， the pressure upper limit set should
be less or equal to the set value.
Manufacturers can modify loading operation time
Manufacturers can modify the total operating time
After Inputting history fault password，the faults will
be completely cleared out.
When (the maximum phase current
≯
phase current )
imbalance protection action stops 。When set value
≥15 ，the imbalance protection is useless.
When open phase time set greater or equal with
20seconds，the Phase doesn't work。If imbalance
protection works，the imbalance protection will act。
If motor overloading stop，only start the machine by
time delay no matter power down or reset to avoid
the motor frequent starting.
