Ammeter
The ammeter shows the load consumption of the blast wheel motor.
When switching on the motor the current value is high (starting current
peak) and falls, after having reached the idle speed, to approximately
10 A. With full load it may rise to a maximum of 35 A.
Hour counter
The hour counter on the main box shows the sum of the actual working
hours performed by the blast wheel.
3.8 Operating elements
The shot valve
Between the abrasive storage hopper and the blast housing there is a
valve in order to control the abrasive flow towards the blast wheel. Any
change in the opening of the valve causes the amount of abrasive fed
to the blast wheel to change. The change in the abrasive fed can be
read from the ammeter. The valve is hand-operated and can be
adjusted so that any quantity of abrasive can be fed to the blast wheel.
Optimum blast cleaning power is reached when the ammeter indicates
35A. It is not permitted to blast with a higher current value.
