LNEYA-18-Positive Pressure Explosion-Proof Cabi - 1

_ ® The adjustment for positive pressure values Adjust the bottom of positive pressure value regulating handle of one-way throttle valve, PXK value will be higher by Clockwise, on the contrary, be lower. It is reasonable to adjust the PXK value to be 250Pa, if the pressure is low and can not be reached to this fine pressure, please kindly check whether the air inlet valve is open totally or not, and if the positive pressure chamber is sealed with the outside and so on. Interlock Function Selection PXK used in the dangerous area 1, if PXK value<50Pa, interlocking contact must be off; If operating in the dangerous area 2, PXK value<50Pa, interlocking contact can be open; But you must deal with in time and ensure the pressure >50Pa, this function by DIP SWITCH U2 the 3rd to adjust, which in the condition of up interlocking contact off, below interlocking contact do not disconnect and to operate in off-state. PXK Constant-temperature Cooling System It auto controls the cooling water into the internal heat exchanger of system to take the heat of PXK away. It can make sure the internal system in the situation of constant-temperature and keep every part safe. WUXI GUANYA REFRIGERATION TECHNOLOGY CO., LTD. Isolated explosion proof (EXdIIBT4) 1.
