contrwsm
a low-voltage relay module (DSIO-LV), 2
consists of a processor module (PSIO)9
EXVs,
an EXV
driver module (DSIO-EXV), a 6-pack relay 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 pro-
vide additional functions. This module is standard on 30GN
modules and is a field-installed accessory on the 30GT
Flo-
tronic II units. See Fig. 1.
The 30G Series standard Flotronic II chillers feature
microprocessor-based electronic controls and an electronic
expansion valve (EXV) in each refrigeration circuit.
NOTE: The 30GN040 and 045 chillers with a
factory-
installed brine option have thermal expansion valves (TXV)
instead of the EXV.
Unit sizes 240,270, and 300-420 are modular units which
are shipped as separate sections (modules A and B). Installation instructions specific to these units are shipped inside
the individual modules. See Table 1 for a listing of unit
sizes and modular combinations. For modules 24OB and
follow all general instructions as noted for unit sizes
110.
For all remaining modules, follow instructions for unit
270B,

Processor Module
ating 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
crease 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 a 3-wire communications 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.

The Flotronic II control system cycles compressor un-
loaders 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 func-
tion, programmed by the user, controls the unit occupied/
unoccupied schedule. The control also operates a test pro-
gram that allows the operator to check output signals and
ensure components are operable.

In the LOCAL/ENABLE position, the chiller is under lo-
cal control and responds to the scheduling configuration and
set point data input at its own local interface device (key-
pad 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.

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
Compressor Protection Control Module (CPCS)
-
Each compressor on models 30GN070 (50 Hz), 080-
100, and 240B, 270B, has its own CPCS as standard equip-
ment. All 30GN040-060 and 070 (60 Hz) units feature the
CPCS as an accessory, and CR (control relay) as standard
equipment. See Fig. 2. The 30GN130-2 10 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-pressure protection
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
gizing the proper 24-v control relay on the relay board. The
CPCS board contains logic that can detect if the
ground of any compressor winding exceeds 2.5 amps. If
this condition occurs, the CPCS module shuts down the
compressor.
A high-pressure switch 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.
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 gath-

ers information from sensors to control the operation of the
chiller. The units use 6 standard pressure transducers and
4 standard thermistors to monitor
system
pressures and temperatures at various points within the chiller. Sensors are
listed in Table 3.

Tables 4A-4D. The unit controls leaving chilled water temperature. Entering water temperature is used by the microprocessor in determining the optimum time to add or sub-

ically reset by the return temperature reset or space and out-
door air temperature reset features. It can also be reset from
an external 4-20 mA signal with a loop isolator, or from a
network signal.
The operating sequences shown are some of many pos-
sible 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.
