The Flotronic II control system cycles compressor unloaders and/or compressors to maintain the selected leaving water temperature set point. It automatically positions the EXV to maintain the specified refrigerant superheat entering the compressor cylinders. It also cycles condenser fans on and off to maintain suitable head pressure for each circuit. Safeties are continuously monitored to prevent the unit from operating under unsafe conditions. A scheduling function, programmed by the user, controls the unit occupied/ unoccupied schedule. The control also operates a test program that allows the operator to check output signals and ensure components are operable.

The contrwsm consists of a processor module (PSIO)9 a low-voltagerelay module(DSIO-LV),2 EXVs, an EXV

driver module (DSIO-EXV),a6-packrelay board, a keypad and display module (also called HSIO or LID), thermistors, and transducers to provide inputs to the microprocessor. An options module (SIO) is used to provide additional functions. This module is standard on 30GN modules and is afield-installedaccessory on the 30GT Flotronic II units. See Fig. 1.

MAJOR SYSTEM COMPONENTS

Processor Module - This module contains the operating software and controls the operation of the machine. It continuously monitors information received from the various transducers and thermistors and communicates with the relay modules and &pack relay board to increase or decrease the active stages of capacity. The processor module also controls the EXV driver module, commanding it to open or close each EXV in order to maintain the proper superheat entering the cylinders of each lead compressor. Information is transmitted between the processor module and relay module, the EXV driver module, and the keypad and display module through a3-wirecommunications bus. When used, the options module is also connected to the communications bus.

For the Flotronic II chillers, the processor monitors system pressure by means of 6 transducers, 3 in each lead compressor. Compressor suction pressure, discharge pressure, and oil pressure are sensed. If the processor senses high discharge pressure or low suction pressure, it immediately shuts down all compressors in the affected circuit. During operation, if low oil pressure is sensed for longer than one minute, all compressors in the affected circuit are shut down. At start-up,the coil pressure signal is ignored for 2 minutes. If shutdown occurs due to any of these pressure faults, the circuit is locked out and the appropriate fault code is displayed.

Low-VoltageRelay Module- This module closes contacts to energize compressor unloaders and/or compressors. It also senses the status of the safeties for all compressors and transmits this information to the processor.

Electronic Expansion Valve Module - This module receives signals from the processor and operates the electronic expansion valves.

Options Module - This module allows the use of Flotronic II features such as dual set point, remote reset, demand limit, hot gas bypass, and accessory unloaders. The options module also aIlows for reset and demand limit to be activated from a remote4-20mA signal. The options module is installed at the factory on040-210and modular 240420 units. It is afield-installedaccessory for 225, 250 and 280 units.

Keypad and Display Module (also called HSlO or LID) - This device consists of a keypad with 6 function keys, 5 operative keys, 12 numeric keys, and an alphanumeric g-character LCD. Key usage is explained in Accessing Functions and Subfunctions section on page 28.

Control Switch - Control of the chiller is defined by the position of theLOCAL/ENABLE-STOP-CCNswitch. This is a3-positionmanual switch that allows the chiller to

be put under the control of its own Flotronic II controls, ,, manually stopped, or put under the control of a Carrier Corn- :f

fort Network (CCN), Switch allows unit operation as shown c ’ _. ’ in Table 2.

In the LOCAL/ENABLE position, the chiller is under local control and responds to the scheduling configuration and set point data input at its own local interface device (keypad and display module).

In the CCN position, the chiller is under remote control and responds only to CCN network commands. The occupied/ unoccupied conditions are defined by the network. All keypad and display functions can be read at the chiller regardless of position of the switch.

CCN run or stop condition is established by a command from the CCN network. It is not possible to force outputs from the CCN network, except that an emergency stop command shuts down the chiller immediately and causes‘ ‘ALARM 52” to be displayed.

Electronic Expansion Valve (EXV) - The microprocessor controls the EXV through the EXV driver module. Inside the expansion valve is a linear actuator stepper motor.

The lead compressor in each circuit has a thermistor and a pressure transducer located in the suction manifold after the compressor motor. The thermistor measures the temperature of the superheated gas entering the compressor cylinders. The pressure transducer measures the refrigerant pressure in the suction manifold. The microprocessor converts the pressure reading to a saturated temperature. The difference between the temperature of the superheated gas and the saturation temperature is the superheat. The microprocessor controls the position of the electronic expansion valve stepper motor to maintain 29 F (16 C) superheat.

At initial unit start-up,the EXV position is at zero. After that, the microprocessor keeps accurate track of the valve position in order to use this information as input for the other control functions. The control monitors the superheat and the rate of change of superheat to control the position of the valve. The valve stroke is very large, which results in very accurate control of the superheat.

Sensors - The Flotronic TM II chiller control system gathers information from sensors to control the operation of the chiller. The unitsuse 6 standard pressure transducers and 4 standard thermistors to monitorsystem pressures and temperatures at various points within the chiller. Sensors are listed in Table 3.

Compressor Protection Control Module (CPCS)

- Each compressor on models 30GN070 (50 Hz), 080100, and 240B, 270B, has its own CPCS as standard equipment. All 30GN040-060and 070 (60 Hz) units feature the CPCS as an accessory, and CR (control relay) as standard equipment. See Fig. 2. The30GN130-210 and associated modular units and the 30GT225, 250, and 280 Flotronic II units have a CR as standard equipment. The CPCS or CR is used to control and protect the compressors and crankcase heaters. The CPCS provides the following functions:

compressor contactor control crankcase heater control

compressor ground current protection status communication to processor board high-pressureprotection

The CR provides all of the same functions as the CPCS with the exception of compressor ground current protection. Ground current protection is accomplished by using a CGF (compressor ground fault) board in conjunction with the CR. The CGF provides the same ground fault function as the CPCS for units where the CPCS is not utilized.

One large relay is located on the CPCS board. This relay (or CR) controls the crankcase heater and compressor contactor. The CPCS also provides a set of signal contacts that the microprocessor monitors to determine the operating status of the compressor. If the processor board determines that the compressor is not operating properly through the signal contacts, it will lock the compressor off by deenergizing the proper 24-vcontrol relay on the relay board. The CPCS board contains logic that can detect if thecurrent-to-ground of any compressor winding exceeds 2.5 amps. If this condition occurs, the CPCS module shuts down the compressor.

A high-pressureswitch with a trip pressure of 426 + 7 psig (2936 +_ 48 kPa), is wired in series with the CPCS. If this switch opens during operation, the compressor stops and the failure is detected by the processor when the signal contacts open. The compressor is locked off. If the lead compressor in either circuit is shut down by the high pressure switch or ground current protector, all compressors in the circuit are locked off.

OPERATION DATA

Capacity Control - The control system cycles compressor to give capacity control steps as shown in Tables4A-4D.The unit controls leaving chilled water temperature. Entering water temperature is used by the microprocessor in determining the optimum time to add or subtract steps of capacity, but is not a control set point.

The chilled water temperature set point can be automat-

Table 4A - Capacity

ically reset by the return temperature reset or space and outdoor air temperature reset features. It can also be reset from an external 4-20mA signal with a loop isolator, or from a network signal.

The operating sequences shown are some of many possible loading sequences for the control of the leaving water temperature. If a circuit has more unloaders than another, that circuit will always be the lead circuit.
