Control variants
The air cannon can be operated using three different control
variants:
• Control by a manual valve:
The air cannon is fired by actuating the valve. The valve is
usually installed directly on the air cannon or in its very close
proximity. Every air cannon must be fired separately.
• Control with an electro-solenoid valve or solenoid valve
cabinet:
The air cannon can be fired by an external signal or directly on
the valve by manual actuation. The valves can be placed
directly on the air cannon or also placed centrally. Firing by an
external signal makes remote and time controlled firing
possible.
Depending on the chosen control variant, only the relevant section
of these installation instructions must be carried out.
NOTE
The air cannon tank can optionally be filled directly using a
separate filling line if filling times quicker than the standard filling
times (see technical data sheet) are required. This must not be
greater in cross-section, however, than the standard filling line;
please also note Figure 8 and follow the instructions below!
NOTE
Make certain when filling the air cannon tank directly that the flow
rate of the filling hose does not exceed the maximum blow-off
capacity of the safety valve. This is 1650 Standard L/min at 8 bar
and 1960 Standard L/min at 10 bar. If the flow rate of the filling
hose exceeds the permissible blow-off values, then it must either
be reduced or a suitably designed safety valve installed.
