Design Specifications DS-300 Revision 02 Model 300 Electronic Batch Controller/Totalizer • Microprocessor based • Totalizer • Batch counter • Moisture resistant sealed front panel • 8 characters, 0.55 inch alphanumeric LED display • Unscaled and factored outputs • 2 set-points, PRESET and PREWARN • Count rates to 20 kHz • Panel lock out/enable • Nonvolatile memory SPECIFICATIONS DESCRIPTION The Brodie Model 300 two-stage electronic Batch Controller is a microprocessor based panel mounted instrument designed to be used in conjunction with primary flow sensors which have a pulse or contact closure output. The main function of the unit is to provide indication and control Accuracy of process batch size. ±1 count The Model 300 factors input pulses into engineering units Mode of Operation and provides two control outputs at adjustable set-points. Single or two-stage controller and/or totalizer Both local and remote start-stop-reset functions are provided. Temperature Operating Temperature: +32°F to 131°F (0°C to +55°C) Selection of counter configurations (reset to zero, set to Storage Temperature: -40°F to +158°F (-40°C to +70°C) preset, and inventory totalization), as well as input scaling, Power Requirements preset levels, decimal locations, software selectable Model 300-00-000-00: 115 Vac ±15% 50/60 Hz or 12 to debounce settings and special security numbers are all 24 Vdc ±10% entered on the sealed front key pad by following the Model 300-00-000-01: 230 Vac ±15% 50/60 Hz or 12 to displayed instructions. 24 Vdc ±10% Note: When DC power is used, no DC outputs are available. PRINCIPLE OF OPERATION Materials of Construction The two-stage batch controller will accept a pulse-type Housing - High impact plastic case with moisture resistant signal or a contact closure as input. The control output front panel. consists of 2 DPDT, 115/230 Vac, 5 amp relay contacts. One relay actuates at prewarn (first stage). The second Dimensions relay actuates at preset complete or end of batch. In See Figure 2 addition to the control outputs, the Model 300 also provides a scaled output and a buffered (unfactored) output to Front Panel Controls (See Figure 1) drive other remote devices. Output voltages of 12 volts Indication - 8 character, alphanumeric LED's grounded and 12 volts isolated are provided to power Programmable decimal point location external sensors and other peripheral devices. Data Entry - 12 button numeric keypad 1 Controls - 4 multifunction push buttons. In the run mode, Isolated 12 Vdc, 100 mA (not available when operated includes separate buttons for start, stop, reset and menu. with dc power) Scaling - K-factor is a four digit number entered in by Relays - 2DPDT - one for PRESET and one for scientific notation. The incoming pulses are divided by PREWARN. (115/230 Vac 5A contact ratings) this K-factor to obtain the scaled quantity for display or Open Collector output. One each scaled (frequency same as indicator batch Range of K-factor selection: count) 0 0.100 EO to (EO equaling 10 ) One each unscaled (same as input frequency) 5 9.999 E5 inclusive (E5 equaling 10 ) Both outputs sink up to 100 mA at 30V Total K-factor range: 0.100 to 999900. Remote reset, start and stop Entry of K-factor is accomplished as illustrated in the Rear terminal connections (active high) following example: External Connections Meter K-factor is 386.3 All power, input and output connections are rear panel 2 Enter: 3.863 E2 (E2 = 10 ) terminals.
