Section 1: General Information
1.1. DESCRIPTION
The model 2800 series is an Intrinsically Safe instrument utilizing Intalogix™ Technology. It is Factory Mutual (FM) Approved for direct use in hazardous environments as shown in the FM Approved Control Drawings.
The 2800 series instrument eliminates the need for explosion proof enclosures or purging systems. Enclosed in a stainless steel, NEMA 4X enclosure, the instrument is able to withstand both wash down and corrosive environments.
Major features of the Instrument include push-button programming and calibration, with data storage in nonvolatile ROM for 100% memory retention.
The 2800 series instrument features a large 1.25 inch high LCD weight display with an additional alphanumeric status display, which can be tilted up or down to accommodate different lighting conditions. Its microprocessor controlled design allows the instrument to be rapidly programmed at installation to meet the specific requirements of the application.
The obtainable accuracy meets Handbook 44 requirements, and the instrument is approved for commercial application up to 10,000 divisions. A maximum of 30,000 divisions can be achieved for non-commercial applications.
This ultra-low power instrument can interface to analog load cells through an
Intalogix™ intrinsically safe controller or can be connected directly to analog load cells using an available optional accessory.
The instrument provides fiber optic interfaces from the hazardous area to the optional accessories located in a safe area. The optional accessories provide communications to various types of peripheral devices in selectable formats for RS232, and 20mA data outputs. Other available options include analog interfaces through programmable setpoints and 4-20 ma analog outputs. The instrument may be powered by a battery or a continuous power accessory.

Section 2: Operation
2.2. SAFETY
As is in the case with any material handling equipment, certain safety precautions must be observed during operation.
Never load the scale platform beyond its rated capacity.
─ Refer to the rating on the serial number plate to be certain.
Ensure that any structure which supports the platform is capable of withstanding the weight of the platform plus its rated capacity load.
Do not load the scale platform if there is any evidence of damage to the platform or supporting structure.
Use safety chains or other suitable restraining devices if there is any possibility of the load shifting, falling, or rolling from its position on the load receiver.
