通常有三种可能会造成该状况，请按照下面的介绍使用排除法依次解除故障，直到机器正
常工作。
Usually there are three possibilities which will lead this situation. Please deal with the
faults in turn with exclusive method according to the following introductions until the
equipment can work normally.
A 气动三联件上的“三通残压阀门”处在关闭状态
The three way residual pressure valve on the pneumatic FRL is at the closed.
请检查该阀门是否处在关闭状态，如是关闭的，请开启。如是开启的，请参照 B 介
绍寻找原因；

Please check whether this valve is closed. If it is closed, please open it. If it is open,
please find the reason according to the B introduction.
B 外部供气线路泄漏，或者外部供气源（空压机）停止工作
The external air supply line leaks or the external air supply power (air compressor)
stop working.
请确认机器左下角的气压表压力是否正常，正常值在 0.4～0.6MPa 之间，如正常，
请参照 C 介绍寻找原因。如不正常，请检查外部气源（空压机）是否正常工作，供气线路是
否有泄漏，排除所有的故障，直到气压表指针指在 0.4～0.6MPa 之间。
Please confirm whether the pressure in the barometer which is assembled in the
lower left of the equipment work normally. The normal value is 0.4～0.6MPa. If the value is
normal, please find the reason according to the C introduction. If the value is abnormal,
please check whether the external air supply power (air compressor) works normally and
whether the air supply line leaks. Exclude all the faults until the value is 0.4～0.6MPa.
C 若“三通残压阀”是开启的，气压表压力又在 0.4～0.6MPa 之间，机器还在报警，请
检查气压表信号线接触是否良好。直到完全排除报警，机器正常工作方可。若以上 3 种方法
均不能解决故障，请电话联系原厂售后辅助解决。
If three way residual pressure valve is open and the pressure value in the
barometer is 0.4～0.6MPa and the equipment alarms, please check whether the signal
connection line of the barometer is good. The equipment can work normally until all the
faults are resolved. If the three methods above can not exclude the fault, please contact
with the after-sale staff from HTGD.
2 紧急按钮按下时报警如图 5-2 所示：
请旋转紧急按钮，使之弹起，解除报警。注意，本机设置了两个紧急按钮，一个在机器
右前面板上，一个在机器后右上角。
The system alarms after pressing the emergent button. See pix 5-2.
Please rotate the emergent button until it bounces, then the alarm is released. Please
note that this equipment has assembled two emergent buttons. One is on the front panel of
the equipment and one on the upper right corner of the equipment.

3 清洗装置不在原点报警，如图 5-3 所示 The system will alarm when the cleaning device
is not at its position. See pix 5-3.
该状况是清洗架不在原点导致的，请打开机器后门，用手将清洗架往后拉，使之回到原
点。然后关上后门，并按下机器前面板上的“RESET”按键，使机器复位，解除报警。
This situation will happen when the cleaning rack is not at its position. Please open the
back door of the equipment, pull the cleaning rack backward and make it back to its position.
Close the back door and press the “reset” button on the front panel of the equipment, then
the equipment will reset and the alarm will be released.
