5.4.4 Pulse Output in Batcher mode
The isolated pulse output (open collector) is menu assignable to Volume Total, Corrected Volume Total or Mass
Total. The pulse output duration can be set for 10mS (50 Hz max) or 100mS (5 Hz max). A pulse output scale
factor (pulse value) can be set to scale the pulse output. The pulse output is ideal for connecting to remote
totalizers or other devices such as a PLC. See section 1.3 for electrical specifications.
5.4.5 Analog Output in Batcher mode
The analog output is menu assignable to correspond to the Volume Rate, Corrected Volume Rate, Mass Rate,
Temperature, Density, Volume Total, Corrected Volume Total or Mass Total. The analog output is ideal for
"trend" tracking using strip chart recorders or other devices.
5.4.6 RS-232 Serial Port Operation in Batcher mode
The RS-232 serial port can be used for programming (using the Setup Disk) or for communicating to printers
and computers in the Operating Mode (Run Mode).
PC Communications:
The Setup Disk also allows the user to query the unit for operating status such as
Flow Rate, Flow Total, Temperature, Density, Presets, etc.
Operation of RS-232 Serial Port with Printers:
Transaction Printing
For transaction printing, the user defines the items to be included in the printed document (see section 6.3.20
SET DATA OUTPUT, Select_list). The transaction document can be initiated by pressing the PRINT key, by a
remote contact closure or print at end of batch.
Data Logging
In data logging, the user defines the items to be included in each data log (see section 6.3.20 SET PRINTER
OUTPUT, Select_list). The user can also select when (time of day) or how often (print interval) the data log is
to be made (see section 6.3.19 SET PRINTER OUTPUT, Configure).
System Setup and Maintenance Report
The system setup and maintenance report lists all of the instrument setup parameters and usage for the current
instrument configuration. The audit trail information and a status report is also printed. This report is initiated in
the Test menu (see section 8.2.3 PRINT SYSTEM SETUP).
