When carrying out defencive function test and communication and interface test, power termination device (5) and pH value transmitter (44) are closed
Two sides valve simulates valve group water resistance by water resistance control valve (43): starting test product water dispenser, after making its operation to declared working condition,
By test product water cooling equipment host simulated failure situation, judges whether its defencive function meets design requirement, carry out protection function
It can test；Whether the uplink and downlink information communication between detection test product water cooling plant host and its Protection control system are normal,
Carry out communication and interface test.
