Resumen del manual
The default value is 100 feet. Note that setting this value to “0” causes the zone to be bypassed during normal operation, and the word “DISABLED” in appear in place of the zone’s PPM reading in the Zone Screen (Page 44). 1. Press the DISTANCE key to adjust the distance value. 2. Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to modify the setting. 3. Press ENTER to accept the new entry or QUIT to revert to the previous setting. Instruction 3015-4275 Average Temperature This temperature reading may be changed to the exact temperature at the sample point for greater accuracy. The adjustment range is from –50 to +70 degrees C. 1. Press the AVG TEMP key to adjust the temperature value. 2. Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to modify the setting. 3. Press ENTER to accept the new entry or QUIT to revert to the previous setting. Current PPM This box displays the last PPM measurement recorded in this zone. You cannot modify this value. Log Interval Sets the length of time between entries in the trend log. The default is one entry every 1440 minutes (24 hours). A value of 000 indicates that each measurement for a given zone is logged into the trend log. 1. Press the LOG INTERVAL key to adjust the log interval value. 2. Use the LEFT/RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keys to modify the setting. 3. Press ENTER to accept the new entry or QUIT to revert to the previous setting. Navigating To the 2nd Zone Setup Screen From Zone Setup Screen #1 press the MORE key to go to Zone Setup Screen #2. Press the BACK key to return to Zone Setup Screen #1. Zone Setup Screen #2 Leak Level This is the concentration level in PPM that will activate a leak alarm condition. 1. Press the LEAK LEVEL key to adjust the value. 2. Use the UP/DOWN cursor keys to modify the setting. 3. Press ENTER to accept the new entry or QUIT to revert to the previous setting. NOTE: This value must be less than the spill level. Instruction 3015-4275 Spill Level This is the concentration level in PPM that will activate a spill alarm condition. 1. Press the SPILL LEVEL key to adjust the value. 2. Use the UP/DOWN cursor keys to modify the setting. 3. Press ENTER to accept the new entry or QUIT to revert to the previous setting. NOTE: This value must be less than the evacuate level and greater than the leak level. Evacuation Level This is the concentration level in PPM that will activate an evacuate alarm condition. 1. Press the EVAC LEVEL key to adjust the value. 2. Use the UP/DOWN cursor keys to modify the setting. 3. Press ENTER to accept the new entry or QUIT to revert to the previous setting. NOTE: This value must be greater than the spill level. Re-Setting the Peak PPM Value Pressing this key resets the current peak PPM level stored in memory and displays it at the top of the screen. Instruction 3015-4275 General Operation Functional Overview Normally each AGM300 will sequentially perform measurements on its active zones without user input. The total time it takes an AGM300 to complete a measurement cycle is directly proportional to the number of active zones and the physical length of the sample-gas lines. Monitors linked together on a network operate independently of each other and consequently complete their respective measurement cycles at different rates. The ADM800 operates by polling the network approximately once every 12 seconds to determine the current status of each AGM300 monitor. If more than one AGM300 is connected to the network, it will sequentially poll each monitor for its status. As a practical matter this simply means that the more complicated the network, the longer it will take the ADM800 to update the status information for all zones. To display all the zones being monitored, go to the System Screen (page 31) and press the ZONES key. Working with the Zone Screen The top level Zone Screen provides a summary view of zone activity across the network. Each screen displays information from a single AGM300 monitor as indicated at the top of the display. Each screen can display information for up to 8 zones, and depending on the configuration of the system, there can be up to two screens for each AGM300. Use the UP/DOWN cursor keys or the NEXT key to scroll the screen display. Each box displays the zone location and the last PPM measurement. A blinking box indicates that a measurement is currently being taken in that location. An inverse flashing box indicates an alarm condition in that zone. Use the LEFT/RIGHT cursor keys to scroll through the zones. Zone Screen To further investigate the status of any zone, press the adjacent key to go to the Zone Setup #1 Screen (Page 41). You may also press the SYSTEM key to go to the System Screen (Page 31). Instruction 3015-4275 Zone Hold Mode A zone can be placed on hold and continuously monitored for a length of time determined by the Zone Hold Time value (Page 38). ...
