Valve Setup
This screen is used to setup the 9210 based on how the flow meter boards are setup. This allows the 9210 to know how display each individual gas flow. There are four gases to select: Nitrogen, Ammonia, Dissociated Ammonia, and Hydrogen. Once a gas flow has been selected, the values for that flow will be displayed in the lower level. The “Zero Scale” selection will allow the user to set the zero scale for the flow. This will display a numeric keypad that can range from 0 to 30,000. The “Full Scale” selection will allow the user to set the full scale for the flow. This will display a numeric keypad that can range from 0 to 30,000. Selecting the “Enable” selection will allow the user to enable the flow. This will cycle between Yes and No. Selecting the “Trim Enable” selection will allow the user to enable the trim flow. This will cycle between Yes and No. The “Target Setpoint” selection will allow the user to set the target setpoint for the flow. This will display a numeric keypad that can range from 0 to 2000. The “Trim Range” selection will allow the user to set the trim range for the flow. This will display a numeric keypad that can range from 0 to 2000. The “Zero SP Scale” selection will allow the user to set the zero scale for the setpoint for the flow. This will display a numeric keypad that can range from 0 to 30,000. The “Full SP Scale” selection will allow the user to set the full scale for the setpoint for the flow. This will display a numeric keypad that can range from 0 to 30,000. The “Valve Max” selection will allow the user to set the valve maximum for the flow. This will display a numeric keypad that can range from 0 to 30,000. The “Flow deviation setpoint” selection will allow the user to set the setpoint for the flow deviation alarm. This will display a numeric keypad that will range from 0 to 30,000. A setpoint of 0 will disable the deviation alarm for the valve. The “Dev. Alarm delay (sec)” selection will allow the user to set the number of seconds before the deviation alarm will sound. This will display a numeric keypad that will range from 0 to 30,000. Note: The deviation alarm delay is entered in 1/10 minutes (6 seconds), so a 2 entered will be displayed as 12 seconds.
Standard Setup for Flow Alarms with Delays
The “Deviation Setpoint” is the flow alarm setpoint, and the “Dev. Alarm Delay (sec)” is the flow alarm delay time
