23. Split mode is most often used in cold climates during periods of low outside air temperature Split mode is also sometimes used when heated refrigerant from the refriger ation system is being used as reclaim heat by an HVAC unit The most common way E2 achieves split mode in an air cooled condenser with single speed fans is to lock OFF 50 of the total number of fans You may choose to lock OFF all odd numbered fans even numbered fans the first half of all fans or the last half of all fans Split mode can also be achieved by activating a valve that bypasses a portion of the tubing in the condenser man ifold The resulting decrease in surface area results in reduced cooling 11 2 5 Fast Recovery Under certain conditions the system pressure may increase too quickly above the condenser setpoint to be reduced effectively by normal condenser control The E2 provides a user definable fast recovery rate setpoint at which all the condenser fans are turned ON to reduce sys tem pressure For air cooled and temperature differential condenser strategies discharge pressure is always used as the control value that determines fast recovery You may choose to enable or disable fast recovery and also to include a delay when transitioning from one mode to the other For evaporative condensers up to 16 override tem perature sensors may be combined to yield a single over ride value that is used for fast recovery Fast Recovery is alway

Kp proportional constant E current error E_ error during last update TR throttling range Throttling Range In simplest terms the Throttling Range is the number of input value units between a 0 output and a 100 out Tries to slow or stop a rapidly changing error so P and I Modes may effectively work to eliminate it put For example in a Case Control application the Throt tling Range would be the number of degrees between the input temperature that would result in a 0 output and the temperature that would cause a 100 output Therefore the Throttling Range essentially determines the percentage of the output adjustment that will be added to the previous percentage when a change in input occurs PID Control places this Throttling Range around the setpoint As a result Proportional Mode works to keep the temperature near the setpoint and within the throttling range In most cases the Throttling Range straddles the setpoint evenly on both sides as shown in Figure D 1 However in some applications such as Condenser Con trol the Throttling Range may be placed elsewhere see Appendix D PID Control D 1 Throttling Range on page D 1 THROTTLING RANGE OUTPUT AT SETPOINT i shown here as 50 100 26512028 Figure D 1 Throttling Range Example 1 Suppose a Case Control application has a throttling range of 10 degrees Also for simplicity s sake assume only the Proportional Mode is a

111. primary goal of a Demand Control appli cation is to make sure that every possible interval of time that might be used by the power company as a demand window will be under the set demand limit This ensures the demand setpoint will never be exceeded 11 11 2 Demand Monitoring The E2 either monitors power using an analog KW transducer which sends the current KW usage via analog signal or monitors energy consumption using a digital watt hour transducer which pulses to signify a fixed amount of watt hours have been used As mentioned in Section 11 11 1 Introduction to Demand Limit Control all KW input values are gathered together and averaged together in a demand window The demand setpoint is then subtracted from this average The result of this calculation is called the integral error or integral of the demand window The integral error rep resents how far below or above the setpoint the input has been for the entire demand window Under non demand conditions the integral error will be below zero since the average KW or watt hour value will be below the setpoint The current value of the integral error and the current value of the KW input are what determine when the Demand Control application will begin load shedding 11 11 3 Load Shedding 11 11 3 1 Definition Load shedding 1s the process of curbing the amount of kilowatt usage within one or more target applications Most applications that drive mechanical or electronic

137. 1 2 1 Strategy Overview of PID Control A Suction Group application looks at suction pressure or suction temperature to determine how many compressor stages should be ON or OFF The application compares the suction pressure or temperature to its control setpoint using PID control The result of this comparison is a per centage from 0 to 100 that corresponds to the total capacity of the compressor rack that should be active The Suction Group application then takes that percent age and determines what combination of compressors Suction Groups should be switched ON or OFF to best fulfill the require ment For example if the application says that 60 of the total compressor rack s power should be active and the rack has compressors totaling 50 HP then E2 will try to switch on compressors totaling 30 HP For more information on PID see Appendix D PID Control 11 1 2 2 Variable Speed Compressors Suction Group applications are compatible with vari able speed compressors VS compressors allow Suction Group applications to fine tune the amount of total active rack horsepower to react to small changes in suction pressures or temperatures As a result the rack does a bet ter job of controlling suction requiring less compressor switches When a variable speed compressor is present it will generally be treated as the primary pressure controlling device and any other standard compressors in the rack are secondary devi
