CONTROLS

General — The 30XW water-cooled liquid chillers contain the ComfortLink™ electronic control system that controls and monitors all operations of the chiller. The control system is composed of several components as listed in the following sec- tions. All machines have a Main Base Board (MBB), Touch Pi- lot™ module or Navigator™ device, electronic expansion valve board (EXV), auxiliary board, Compressor Protection board, Emergency On/Off switch, and an Enable-Off-Remote Contact switch.

Main Base Board (MBB) — The MBB is the core of the ComfortLink control system. It contains the major portion of operating software and controls the operation of the

machine. See Fig. 8. The MBB continuously monitors input/ output channel information received from its inputs and from all other modules. The MBB receives inputs from status and feedback switches, pressure transducers and thermistors. The MBB also controls several outputs. Some inputs and outputs that control the chiller are located on other boards, but are transmitted to or from the MBB via the internal communica- tions bus. Information is transmitted between modules via a 3-wire communication bus or LEN (Local Equipment Net- work). The CCN (Carrier Comfort Network®) bus is also sup- ported. Connections to both LEN and CCN buses are made at TB3. For a complete description of Main Base Board inputs and outputs and their channel identifications, see Table 3.
