The 2000 series CAN system is the system that is presently used for all air leveling systems except thoseused for Prevost busses. The Active Air system is a CAN system with a different type of system control.CAN stands for Controller Area Network. The CAN system has a central control module with a “mother”board along with input and output modules that the central control module controls. A simple CAN systemwill only have only two modules or boxes; a central control/output box and a touch panel. In a CANsystem, the touch panel is considered a module. A complex CAN system can have an almost unlimitedamount of control boxes or modules. Except for one or two possible exceptions, all air leveling only CANsystems will have only the two modules; the control box and the touch panel.3-2.2 Touch panels. There are several different styles of touch panels for air leveling systems. It isimportant to get the correct part number when replacing a touch panel. A replacement panel with the samelexan (touch panel decal) and cable connector may not be compatible with the existing panel. Some touchpanels may have a small sticker on the back with the panel part number. Some will have the part numberwritten on the pc board with a felt pen. If no part number is available, get the part number off the controlbox. With the control box number, the correct touch panel part number can be determined by HWH. Thefollowing panels are examples of what is available. When part numbers are not available, contact HWHCorporation technical assistance. Do not order a touch panel unless you are positive of the correct partnumber.Page 12 – 22JUL09
