Hopper startup
Supply air to the hopper must always be present prior to applying electrical power to the hopper.
Electrical power must always be cycled/applied after supply air has been removed and reapplied to the
hopper. This allows for proper cycling/sequencing of solenoid valves, regardless of which pinch valve
housing or PLC code is onboard the hopper.
If you did this... Do this for startup
Shut off supply air to the hopper, but left
the hopper powered on
Apply supply air to the hopper first, and then cycle power
to the hopper (off, then on again).
Turned off power to the hopper, but left
the supply air on
Power on the hopper.
Shut off both supply air and power to
the hopper
Apply supply air to the hopper first, and then power on
the hopper.
To shut down the hopper
Shut down the machine, and then turn off the power switch to the hopper.
