Operator Alarms
No Flow Alarm
The PC200 offers a no-flow monitoring feature: if the flow meter fails to generate a signal during a certain period of time, the
unit will shut off the control outputs and bring the batch controller in HOLD and alarm mode. A “NO FLOW” alarm message
will display.
To clear the alarm, press RESET once while the batch controller remains in HOLD mode. When in HOLD mode, the batch can
be continued or interrupted. See “Interrupting and Ending the Batch Process” on page19.
Flow Rate Alarm
If during a batch process the actual flow rate is outside the allowed range, a “LO RATE”, or “HI RATE” alarm message will display,
indicating the type of alarm: “LO RATE”, “HI RATE”.
Based on the configuration setting 4.5 Reset Flow Rate Alarm, the following will happen:
• Auto mode: The process is not interrupted, the alarm cannot be cleared and will disappear once the flow rate is within its
limits again.
• Manual mode: Press FLOW RATE followed by RESET to acknowledge the alarm; the alarm will disappear. The alarm will be
cleared automatically in case the batch process is ended.
• Hold mode: The batch process will go on HOLD automatically as soon as the flow rate is outside the allowed range. To clear
the alarm, press RESET once, while the batch controller remains in HOLD mode. When in HOLD mode, the batch can be
continued or cancelled completely. See “Interrupting and Ending the Batch Process” on page19.
Alarm 01-03
If “ALARM” is displayed when no process alarm is present (no flow or flow rate alarm), press the “1” key to display the reason for
the alarm.
