6.6 Manual Control Screen
The Manual Control screen is accessed from the Main Screen. When the STORM™ sampling
system is selected in Manual mode, the operator can energise each solenoid valve individually.
Control Functions
The ‘VACUUM CONTROL VALVE’ controls the vacuum generator. Energising this valve will
generate a vacuum and draw a sample up into the sample cylinder.
WARNING: Failure to de-energise this valve when the settling cylinder is full may permanently
damage the vacuum generator.
The ‘AIR PURGE VALVE’ is used to discharge the sample from the settling cylinder.
The ‘WATER FLUSH VALVE’ is used to spray clean water into the settling cylinder and clean the
turbidity probe sensor.
The ‘AIR VENT VALVE’ allows air to enter the settling cylinder while the sample is being
discharged.
The ‘SAMPLE TEST’ button is used to test the sampling function. The operator should press-
and-hold this button while a test sample is drawn up into the settling cylinder. When the
sample level reaches the level probe the sample suction should stop and the sample should be
held steady in the settling cylinder. When the operator releases the ‘SAMPLE TEST’ button the
sample will be returned to the centre-well.
WARNING: Failure to properly connect the level probe may cause the Settling Cylinder to
overfill and permanently damage the vacuum generator.
