Backlit display with LCD backup Overview The 515 BR02 application is a batching flow controller for delivery of preset quantities at preset flowrates using a volumetric analog input. Batch control can operate in preset or on-off modes, while flow control can be set to local (manual) or PI loop mode.
The front panel display shows the current values of the input variables and the results of the calculations. The instrument can be supplied with a real-time clock for storage of up to 1000 transactions with time and date stamps. 515 BR02 - 17 June 2017...

• ASCII - In this ASCII protocol each command and response is a string of ASCII characters. This proprietary protocol is developed by Contrec to allow for simple information interchange. The main advantages of this mode are that it allows extended time intervals to occur between characters without causing a timeout error and that messages can be sent and monitored easily with a simple ASCII terminal.
Likewise, there is only one set of current process variables with “non-accumulated totals”, therefore it also ignores any log number included in that request. 515 BR02 - 17 June 2017...
