Changing Motor Rotation Direction
If the motor is rotating in the wrong direction, do the following:
1. Disconnect the power at the external disconnect.
2. Switch any two incoming power leads on the main power supply.
Caution! Do not change wiring at the motor starter!
Starting the System
After you completely install the conveying system and make all pre-startup checks, perform
the following procedure to operate the system.
1. Turn on compressed air to the power unit solenoid valve and set the supply regulator
at 80 psi (551.6 kPa/5.52 bars).
2. Close the disconnect switch on the electric supply circuit and on the vacuum pump
package.
3. Move the ON/OFF switch in the ON position.
Note: The pump does not turn on until the first dump delay is complete. Conveying
then begins.
4-3 Control Panel Components
Once the controller has been configured according to the instructions listed in Section 3-4,
The only procedure necessary to begin conveying, is to turn on the controller using the Power
toggle switch described below. If the controller is equipped with the Optional Material
Receiver Selector Switch, then the operator will need to select the material receiver to convey
to before turning on the Power toggle switch on the controller.
Material Receiver Selector Switch (Optional)
The MATERIAL RECEIVER SELECTOR switch (Shown in Figure 4 on Page 19) allows
you to select the material receiver from multiple material receivers for time-filling. It is
typically used in railcar unloading processes.
Control Power Indicator Light
The CONTROL POWER indicator light illuminates when the control panel energizes.
Control Power Toggle Switch
The CONTROL POWER switch starts or stops the conveying cycle. If you selected a
material receiver with a material demand condition, the cycle begins. This switch also lets
you turn the vacuum pump or blower on and off.
