SECTION 1.0 DESCRIPTION The Eagle Microsystems C3600P and C7200P Precision Ton Container Scales are designed specifically for the water and wastewater industry. They incorporate 4 stainless steel shear beam load cells with integral overload stops. The C3600P and C7200P are supplied with the required amount of rollers for easy rotation of ton containers. Each scale is supplied with 15' of cable. Additional lengths are available upon request.
3. Use strong banding to secure scale in shipment. 2.3 SITE SELECTION 1. Extreme temperature variations may cause the scale to drift slightly off zero. Your precision ton container scale has temperature compensated load cells to minimize such effects. However, whenever possible, avoid placing your scale near air ducts, heating or cooling elements, doors opening to the outside, ect. to minimize temperature effects. 2.
3. Using wrench to tighten all corners 2.6 HOOK-UP CABLE Figure 2 shows the wiring connections necessary to attach the platform to the read-out instrument. The color code and function are as noted. Consult read-out manual for the required information for its hookup. (Most scales are shipped with mating connector for easy hook-up to the instrument supplied) COLOR CODE BLACK WHITE RED GREEN YELLOW FIG. 2 SECTION 3.
