1.0. GENERAL 1.1. Description The DC-180 counting scale offers a practical solution to a full range of precision counting applications. There are a variety of models available ranging from a weight capacity of 0.5 lb. through 100 lb. utilizing an internally mounted load cell and a full range of capacities from 0.5 to 50,000 lb. utilizing an external second platform. A console model is also available with 1 external platform in any of the above mentioned capacities in any combination.

3.0. INSTALLATION This section provides the information required for installing this counting system For operation. The following steps accomplish installation. 1. Unpacking 2. Set-up Procedure 3.1. UNPACKING Each component of the DC-180 system is packed in a specially designed carton. Remove each component from its carton, separate the component from its polystyrene shell assembly and set aside. Inspect the carton interior to be sure that all accessories have been removed from the carton.
3.4. Unlocking Procedure (Continued) for 5LB. To 50LB. Scales INITIAL SET-UP PROCEDURES Before setting up the scale, remove the load cell locking screws located at the bottom of the scale as shown in the diagram below. Warning! Do Not Turn Scale Upside Down. To Lock Scale for shipping: 1. Install cap screw finger tight. 2. Install allen screw finger tight, 3. Then install nut, just snug. Do the following steps before scale calibration. A) Place the platter on the platter support of the scale.
Do not unplug remote scale from the DC-180 while the DC-180 is powered. 3.4. Unlocking Procedure (Continued) for 1LB. and 2.5LB. Scales The above drawing is for illustration purpose only. Warning! Do Not Turn Scale Upside Down. SET UP PROCEDURES Do the following steps before scale calibration or operation. 1. 2. 3. 4. Take off nut (A) and four screws (C), then take off plate. Loosen nut (B) and screw (D) , then take off screw (D) , nut (B) and insert.
4.0. DC-180 AC / BATTERY OPERATION The DC-180 can be operated with AC power or with the optional internal battery. The battery will automatically charge whenever the scale is plugged into AC power. The charging current is regulated by a battery monitor circuit, so that the battery can not be overcharged. The DC-180 system is powered internally at a low power level whenever the scale is plugged into the AC line or the battery switch is in the “ON” position.
