3.3 Optional electric remote controls
Figure 3: Electric remote controls and pneumatically or manually operated abrasive metering valve.
In order to reduce the time to stop blasting (especially when using longer blast hoses), the twinline
hose between the deadman handle and the remote control valve is replaced by an electric cord
(orange) and the electric panel RME-1 (item 15). The magnetic valve converts the electric signal into
a pneumatic signal.
3.4 Optional remote control with dual function
This option can only be applied with pneumatically operated media metering valves and is
especially recommended for very long blast hoses and to blow off the blasted surface with
compressed air.
An additional switch on the deadman handle enables the operator to open or close the pneumatically
operated media metering valve during blasting (deadman handle depressed).
