Multi-Zone Gas MonitorsP/N: 3015-5074 Rev 11 31SECTION 4. GENERAL OPERATION4.1. Functional OverviewNormally each MZ monitor will sequentially perform measurements on its active zones without user input.The total time it takes a MZ monitor to complete a measurement cycle is directly proportional to the numberof active zones and the physical length of the air lines. Monitors linked together on a network operateindependently of each other and consequently complete their respective measurement cycles at differentrates.The Remote Display operates by polling the network approximately once every 12 seconds to determine thecurrent status of the MZ monitors. If more than one MZ is connected to the network, it will sequentially polleach monitor for its status. As a practical matter this simply means that the more complicated the network,the longer it will take the RD to update the status information for all zones.4.2. The Zone Setup ScreenFrom System Setup Screen #2, scroll down to select the ZONES option.Figure 4-1. Zone Setup Screen #14.2.1. LocationThis is the name you assign to the MZ monitor to identify the zone location. It may have up to 12alphanumeric characters.1. Press the ENTER key to adjust the setting.2. Use the LEFT/ RIGHT cursor keys to move across the entry field and the UP/DOWN cursor keysto modify the individual characters.3. Press ENTER to accept the new entry or ESC to revert to the previous setting.4.2.2. Gas/ Refrigerant TypeThis parameter defines the kind of gas the MZ is detecting.1. Press the ENTER key to adjust the setting;2. Use the LEFT/RIGHT cursor keys to select the type of gas you want the device to detect. (Optionsdiffer depending on model).3. Press ENTER to accept the new entry or ESC to revert to the previous setting.
