UCP2 Control Panel and Module Description

Unit Control Panel

Safety and operating controls are housed in the UCP2 Unit Control Panel, the Starter Panel and
the Purge
Figure 1
Control Panel (Control Panel layout is illustrated in ).
The UCP2 control consists of a modular design partitioned by major function or group of
functions. All modules communicate with each other through the IPC circuit.
Major components within each of these control groups are described below.
Unit-mounted temperature sensors, pressure transducers and functional switches provide
analog and binary inputs to the various modules.
The "microprocessor-based" modules described are shown below. All connections to the
modules are made with pluggable phoenix connectors.
