Wiring Considerations
The wiring of your blender is very important to its proper operation. Electronics are very susceptible to voltage spikes and static
charges, both of which are very common in plastics factories.
To MINIMIZE these things, consider the following:
•
The power supply should be solid; a strong supply, not limited by a "just adequate" control transformer. A source
of voltage that comes from a large transformer that supplies a large portion of the plant is better then a small
power supply transformer that is intended to supply only this device. Power supplies, even though they may be
"isolation" transformers, will still pass all voltage spikes right through. Their small size limits their ability to dampen
RF (Radio Frequency) noise that is often induced into the system from outside sources. This proves worse then
connection to larger central transformers.
•
Avoid running the power supply line along side any heavy power lines. An unshielded power supply in a
raceway along side other heavy power lines will pick up induced RF noise and transfer it into the WSB steel
enclosure causing computer trouble.
•
Long extension cords should be avoided. They also reduce the ability to provide a dampening effect on spikes
and static. The further the equipment is from a substantial power source, the more susceptible it is to spikes.
•
The CONTROLLER and the WSB frame MUST share the same GROUND PATH. This is why you MUST plug the
controller into the OUTLET that is provided ON THE FRAME.
•
REMOTE SYSTEMS. If you have your controller mounted in a remote location, you will have a number of power
and signal cords running between the frame and the controller. BE SURE that the LOW VOLTAGE lines are NOT
BUNDLED to the HIGH VOLTAGE lines and keep them away from other nearby electrical lines.
LOW VOLTAGE lines are: Load Cell cable, Level Sensor cord, Air Solenoid cable, and Printer and Computer
cables.
HIGH VOLTAGE lines are: Mixer motor cable, Feeder motors, and MAIN POWER line.
Keep these sets of cables SEPARATED.
•
VACUUM LOADER CONVEYING LINES. Keep them away from all electrical lines, particularly the Load Cell lines.
Conveying plastic produces extreme static sources. A power supply line, even in conduit, that runs next to a
vacuum line, can introduce extreme static pulses into the processor. Keep conveying lines SEPARATED from
electrical supply lines.
•
We use many internal tooth "STAR" washers in assembling the WSB to ensure good ground between painted
parts. Do not remove them.
