Process Control functions are configured from the Setup Mode as described in section
5.4.4 above. In addition, you can interact with Process Control functions in Run Mode
using Process Control Screens for each of the three relay channels. On these screens,
you can inspect alarm status, clear alarms, dispense fluid batches, etc. Use of the Setup
Mode has been discussed above. This section covers the use of the Process Control
Screens.
To access Process Control Screens from the Run Mode Screen, press the RELAY
soft button. This button does not appear (the soft button label is blank) if the Process
Control option is not fitted to the flowmeter. None of the functions discussed in this
section are available without the Process Control option. Additionally, either the
Model S3 display option or the Communications Board and a connected User PC
Software Application are necessary to perform the operations described. You must
have at least one of these if they have a Process Control Board, otherwise it will be
useless.
In Run Mode, Process Control functions are accessible in from the Process Control
Screens. Pressing the RELAY soft button moves in a circular fashion from relay to relay
and then back to the Run Mode Screen. Only those relay channels are visited that are
configured to monitor Rate or Total in the active configuration. Relay channels that are
disabled are skipped. If all relays are disabled, the RELAY soft button does not appear
on the Run Mode Screen. This soft button is in the same location on the Run Mode

For relay channels monitoring Flow Rate, a CLEAR soft button allows you to de-activate
a relay that has been energized due to the rate reaching the trigger settings (see section

For relay channels monitoring Flow Total, a START soft button allows you to start the
dispensing of a batch (see section 8.2.1 below for details). Also for channels configured for
Flow Total, and soft buttons allow you to select certain of the
settings and status values. According to which is selected, a CLEAR or EDIT soft button
appears.
Pressing the CLEAR soft button zeros the selected total. Pressing the EDIT soft button
allows the Batch Amount to be changed. (See section 8.2 below for details and
restrictions.) When the Process Control Screens are displayed, the flowmeter
continues to operate normally in Run Mode. Flow is measured and totalized and all
logging, monitoring and output signal functions continue uninterrupted. The SETUP
soft button is not available. To leave Run Mode, first return to the Run Mode Screen
using the RELAY soft button.
