Overview
The 505 BC01 application is a dual stage batch controller for reliable measurement of preset quantities using a volumetric frequency input. Used as a single or dual stage contoller it is suitable for fast batch applications.
It provides the operator with clear local readout and can be controlled via communications in more automated systems. There is quick access to commonly used preset values directly from the front panel if access has been authorized. Automatic overrun compensation caters for system delays such as valve closure for precise volumes.
The instrument is compatible with a wide range of flowmeter frequency outputs, including millivolt signals, reed switches, Namur proximity switches and pulse trains via its smart front-panel program selection.
Calculations
The total and flowrate are derived from accurately measured frequency and the number of received pulses.
volume = pulses / k-factor
volume flow = frequency / k-factor
Automatic overrun compensation calculates the new valve closure point to ensure correct delivery by averaging the overrun amount from the last three complete batches.
The overrun compensation value is valid for a new preset value provided the stored overrun is less than 20% of the new preset.

Displayed Information
The front panel display shows the current values of the input variables and the results of the calculations. A list of the variables for this application and their type (total or rate) is shown at the end of this document.
The instrument can be supplied with a real-time clock for storage of up to 100 transactions with time and date stamps.
Communications
There are three communication ports available as follows:
- RS-232 port
- RS-485 port
- Infra-red port (optional)
The ports are available for remote data reading, printouts and for initial application loading of the instrument.
Retransmission & Control Outputs
The instrument can retransmit any main menu variable.
The digital outputs can retransmit totals as pulses or operate as logic levels for control or error outputs. If the instrument has the advanced option, it outputs rates as a 4-20 mA signal.
Relay Outputs
The relay outputs 1 and 2 are used to control the flow of product for each delivery. These contacts are normally open and can be used to drive external relays, valves, pump circuits etc.
Software Configuration
The instrument can be further tailored to suit specific application needs including units of measurement, custom tags, second language or access levels. A distributor can configure these requirements before delivery.
Instrument parameters including units of measurement can be programmed in the field, according to the user access levels assigned to parameters by the distributor.
All set-up parameters, totals and logged data are stored in non-volatile memory with at least 30 years retention.
