What functional abnormalities will be encountered during the use of the rain test chamber

Rain test chamber is generally suitable for external lighting and signaling devices and automotive lamp shell protection, can provide a realistic simulation of electronic products and their components may be subjected to a variety of environments
such as water and spray tests during transportation and use.

What functional abnormalities will be encountered in the use of the rain test chamber? And what to do? 1.
Pendulum pipe is not moving: check whether the parameter setting is correct, check whether the pendulum tube motor is normal
.

2, the equipment can not be opened: check whether the water tank is short of water
.

3, the equipment is out of power: check whether the power supply is normal, check whether the phase sequence is wrong, and whether the equipment has zero connection
.

4.
The turntable does not rotate: check whether the parameters are set correctly, and check whether the turntable motor is working
.

5.
Do not spray water when it rains: check whether the water pressure is normal, check whether the pump is working, and check whether the nozzle is blocked
