Detailed instruction
pre-alarm by changing BIT8 of P19.13 to 1.
When the current exhaust pressure is detected to
be above P18.18, the system releases pressure
alarm by changing BIT10 of P19.13 to 1 and
emergency stop will be applied.
Setting range: 0.00–P18.04
When head temperature is detected to be above
P18.19, system releases temperature pre-alarm
by changing BIT9 of P19.13 to 1.
When head temperature is detected to be above
P18.20, system releases temperature alarm by
changing BIT11 of P19.13 to 1 and emergency
stop will be applied.
When head temperature is detected to be below
P18.21, system releases low temperature
pre-alarm by changing BIT14 of P19.13 to 1 and
the air compressor will be prohibited from
starting.
Setting range: -20–150
It is used to correct P19.10.
Setting range: 0%–200%
Set the sampling cycle of temperature PID
Setting range: 0.0–10.0s
It determines the adjustment intensity of
temperature PID regulator. The larger the kp, the
stronger the intensity, however, too strong the
intensity may cause temperature oscillation. It is
viable to make adjustment based on factory
value according to actual conditions.
Setting range: 0.0–100.0
It determines the convergence speed of
temperature, PID regulator. The larger the value
of K, the stronger the intensity, however, too
