5-2 Preventative Maintenance

Our blenders need periodic maintenance to provide long dependable service. Check these elements regularly:

•Check functionality of safety circuit daily.

•Maintain proper air pressure and drain water from trap assembly on regulator – as required.

•Periodically lubricate slide gate rails.

WARNING! Always remove plug and disconnect power before servicing blender.

WARNING! Always read operating manual before operating or servicing blender.

5-3 Corrective Maintenance

Electrical

This section is designed to give the operator an overview of the electrical system that controls the Slide Gate/Auger blending system. Since the blender’s control panel is a self-contained pluggable item, seldom will a maintenance person be required to enter the control panel. For purposes of understanding the system, it is advisable that the maintenance personnel be familiar with not only the internal workings of the control panel, but also with the input and output signals to the Slide Gate/Auger blender.

This section includes the following:

•Internal components of the control panel

•Input signal to the control panel

•Output signals from the control panel

Internal Components of the Control Panel

Note: See Installation Packet supplied with unit for complete electrical schematics.

This section describes the internal components of the Slide Gate/Auger blending system control panel. It is not the intent of this section to completely familiarize the reader with the details on industrial control panel construction or standards, but simply to familiarize the reader with the major components inside the control panel.

The customer must supply 120/1/50 or 60 (or 220/1/50 or 60) via wires L1 & L2 (N). Please insure that the earth ground connection is properly connected to an established earth ground.

•“Power on” is indicated by a lighted on/off switch.

•“Slide gate below mixer” switch controls position of optional slide gate.

•“Safety Active” light displays status of safety interlock circuit. Audible alarm horn alerts operator to blender fault.
