P18.17
Pre-alarm
pressure
When current discharge pressure is higher
than P18.17 , the system indicates pressure
pre-alarm by setting BIT8 of P19.13 to 1.
When current discharge pressure is higher
than P18.18 , the system indicates pressure
alarm by setting BIT10 of P19.13 to 1, and
emergency-stop will be applied.

Pre-alarm
temperature
When machine head temperature is higher
than P18.19 , the system indicates
temperature pre-alarm by setting BIT9 of
P19.13 to 1.
When the machine head temperature is
higher than P18.20 , the system indicates
temperature alarm by setting BIT11 of
P19.13 to 1, and emergency-stop will be
applied.
When machine head temperature is lower
than P18.21 , the system indicates
low-temperature pre-alarm by setting BIT14
of P19.13 to 1, and air compressor cannot
start.

Gain coefficient
(kp)
It determines the regulation intensity of
temperature PID regulator, the larger the
value of kp, the stronger the regulation
intensity, however, if it is too large,
temperature oscillation may occur, users can
fine-tune based on the default value.
