Menu System Details

 

P1.00: Process Variable –These values are read-only and are meant for diagnostic purposes.

  • P1.10: Inlet Pressure – Line Pressure measured by the high pressure sensor; the value is based on the unit set in P2.20.

  • P1.20: Gas Temperature – Line Temperature; the value is based on the unit set in P2.30.

  • P1.30: Differential Pressure – Difference in pressure measured between the high and low pressure sensors; the value is based on the unit set in P2.20.

  • P1.40: Revision Information – For internal use only.

  • P1.50: Diagnostic Readings – For internal use only.

 

P2.00: Process Options – These values are modifiable and change how the user views the flow rate and process variables. 

  • P2.10: Flow Units – Unit of flow rate displayed.

  • P2.20: Pressure Units – Unit of pressure displayed.

  • P2.30: Temperature Units – Unit of temperature displayed.

  • P2.40: Display Average – Increasing this value will increase the average of the flow rate being displayed on the main screen (range for this value is 1 to 255).

 

P3.00: User Alarms – Values are modifiable and allow the user to set custom high and low flow alarms as well as low pressure alarms in addition to the factory low and high pressure alarms.

  • P3.10: Low Flow Alarm Limit – Triggers an alarm if the flow drops below the programmed value (0 = alarm not set).

  • P3.20: High Flow Alarm Limit – Triggers an alarm if the flow increases above the programmed value (0 = alarm not set).

  • P3.30: Low Pressure Alarm Limit – Triggers an alarm if the supply pressure drops below the programmed value (0 = alarm not set).

NOTE:Factory high pressure alarm is not viewable or editable.

  • P3.40: Deviation Alarm – Triggers an alarm after 60 seconds if the flow PV deviates from the flow SP more than the defined deviation (0 = alarm not set).

  • P3.50: Factory Alarm Disable – Disables three preset factory alarms given in P3.51 – Under Pressure, P3.52 – Valve Shut, and P3.53 – Max Opening  (on = alarm is disabled).

 

P4.00: Serial Communications – Values are modifiable and are used to set the serial communications.

  • P4.10: Baud Rate

  • P4.20: Address

  • P4.30: Parity Bits

 

P5.00: Ethernet Communications – Values are modifiable and are used to set the Ethernet Settings.

  • P5.10: DHCP – Enabling allows the unit to automatically obtain addressing.

  • P5.20: IP Octet – Used to manually set the IP address of the device.

  • P5.30: Subnet – Used to manually set the Subnet of the device.

  • P5.40: Gateway – Used to manually set the Gateway of the device.

 

P6.00: Setup – Values are modifiable and changes important device options.

NOTE: These options should ONLY be changed if absolutely necessary.  Please contact SSi before making changes to these settings.

  • P6.10: Zero Tare – Resets the zero flow rate of the meter (manual mode with valve closed only).

  • P6.20: Analog Max Flow – Sets the 4-20mA analog in and out based on desired max flow rate allowable.

  • P6.30: Control Mode – Sets control method of the meter.  Options include Flow mode, Valve mode, Manual mode, and Ratio mode. 

    • Flow mode refers to standard control based on a specific flow setpoint for use with standard gases. 

    • Valve mode refers to valve position control based on % output (commonly used for carbon control gases). 

    • Manual mode is used for analog flow meters and in-line meters, which do not contain valve motors for automatic flow control. 

    • Ratio mode is used for specific applications involving ratio control like mixing systems.

  • P6.40: Gas Type  – Used to set the gas type of the meter. NOTE: changing this value may limit the amount of flow indicated by the info tag on the front of the meter.

  • P6.50: Max Valve Position Tare – Sets the max position the valve is capable of driving to in valve position mode (manual mode with valve opened to desired max flow rate).

  • P6.60: Altitude Compensation – Sets the altitude for the installed location.  Units are feet above sea level.

  • P6.70: Decimal Point Override – Allows the flow to display with no, 1, or 2 decimal points.

  • P6.80: Control Override – Allows temporary digital control of the meter assuming that the meter set point is being controlled with an analog signal.  When set to “Auto”, the meter can be remotely controlled with a digital or analog signal. This feature is for special uses.  Contact SSi for more details about this option.
