Page 16 of 118 SGB Batch Blender with Mitsubishi Controller
Each of the diamond gate air cylinders is actuated by a solenoid valve,
which are controlled by the blender.
When the solenoid valve is energized, it opens the metering valve
cylinder. When the solenoid valve is de-energized, it closes the
metering valve cylinder.
If the power is interrupted to the blender, the metering valves will return
to the closed position, to prevent material from over-filling the weigh
hopper/mix chamber.
Important! If the blender is in metering mode with one of the slide gates open,
do not open the front door of the blender!
The safety switch shuts off the air supply to the blender. An open
feeder slide gate stays open, and an overflow of the weigh hopper
can occur!
