The Tower Start Determination module enables the cooling tower subsystem whenever the system enable is true, or a condenser water pump is on. This module monitors the System Enable input and the CW Pump Sequencer. The cooling tower subsystem is not disabled until System Enabled is False, all condenser water pumps are off, and a user-defined delay has expired. This module has inputs for the user-defined delay, System Enabled, and the number of active pumps. It has a single state output which indicates whether the cooling tower subsystem should be enabled or disabled.
