state-of-the-art chiller protection. The system controls cooling
load within the set point plus and minus the dead band by sensing the water or brine temperature and regulating the inlet
guide vane via a mechanically linked actuator motor, and regulating VFD (variable frequency drive) speed if the compressor
is powered by a variable speed drive. The guide vane is a variable flow pre-whirl assembly that controls the refrigeration effect in the cooler by regulating the amount of refrigerant vapor
flow into the compressor. An increase in guide vane opening
increases capacity. A decrease in guide vane opening decreases
capacity. The microprocessor-based control center protects the
chiller by monitoring the digital and analog inputs and executing capacity overrides or safety shutdowns as necessary.
The PIC 5 control system also provides access to a Control
Test function covering all outputs except compressor relay outputs.

WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. Use lock
out/tag out procedures and be aware that there may be
more than one disconnect switch. Be sure to tag all disconnect locations to alert others not to restore power until work
is completed. Even when the main circuit breaker or isolator is switched off, certain circuits may still be energized,
since they may be connected to a separate power source.
WARNING
Abbreviations Used in This Manual —
Electrical currents cause components to get hot either temporarily or permanently and may cause burns. Handle
power cable, electrical cables and conduits, terminal box
covers, and motor frames with great care.

CAUTION
This unit uses a microprocessor control system. Do not
short or jumper between terminations on circuit boards or
modules; control or board failure may result.
Be aware of electrostatic discharge (static electricity) when
handling or making contact with circuit boards or module
connections. Always touch a chassis (grounded) part to
dissipate body electrostatic charge before working inside
control center.
Use extreme care when handling tools near boards and
when connecting or disconnecting terminal plugs. Circuit
boards can easily be damaged. Always hold boards by the
edges and avoid touching components and connections.
This equipment uses, and can radiate, radio frequency
energy. If not installed and used in accordance with the
instruction manual, it may cause interference to radio communications. The PIC 5 control boards have been tested
and found to comply with the limits for a Class A computing device pursuant to International Standard in North
America EN 61000-2/3 which are designed to provide reasonable protection against such interference when operated
in a commercial environment. Operation of this equipment
in a residential area is likely to cause interference, in which
case the user, at his own expense, will be required to take
whatever measures may be required to correct the interference.
Always store and transport replacement or defective boards
in anti-static shipping bag.

HARDWARE
The PIC 5 control system consists of one main control
board, an ISM (integrated starter module), and four IOBs (input/output board modules). All boards communicate via an internal LEN bus.
Main Control Board — The main control board is sup-
plied from a 24 VAC supply reference to earth ground. In the
event of a power supply interrupt, the unit restarts automatically without the need for an external command. However, any
faults active when the supply is interrupted are saved, and may
in certain cases prevent a circuit or unit from restarting. Figure
1 shows the main control interface and connectors.
CAUTION
Maintain the correct polarity when connecting the power
supply to the boards. Otherwise, the boards may be damaged.
GENERAL

controlling two-stage 19XR semi-hermetic centrifugal liquid
chillers.
The PIC 5 control system monitors and controls all operations of the chiller. The microprocessor control system matches
the capacity of the chiller to the cooling load while providing
ISM (Integrated Starter Module) — The ISM is the

Sensors
Controls Outputs
PRESSURE TRANSDUCERS — Pressure transducers measure and control the pressures in the unit. These electronic sensors deliver 0 to 5 VDC. The transducers can be calibrated
through the controller. The pressure transducers are connected
to the IOBs. See Table 6.
EVAPORATOR/CONDENSER WATER PUMP — The
controller can regulate an optional evaporator/condenser water
pump.
INLET GUIDE VANE — The inlet guide vane adjusts the
refrigerant vapor flow into the compressor to adapt to change
in the operating conditions of the machine. To adjust the refrigerant flow, the guide vane opens or closes to vary the crosssection of the refrigerant path. The high degree of accuracy
with which the guide vane is positioned ensures that the flow
of refrigerant is precisely controlled.
ECONOMIZER DAMPER VALVE — The economizer
damper control opens or closes the economizer damper valve
to maintain a minimum refrigerant pressure difference between
the evaporator and economizer.
HGBP VALVE — The hot gas bypass function artificially
loads the chiller and keeps it running under low load conditions or helps to prevent surge conditions. Since this function
can also reduce the operating efficiency of the machine, this is
a user-selectable and configurable option.
VFD — The VFD modifies motor frequency to allow compressor start-up and capacity control. The VFD controls continually monitor parameters in order to ensure compressor
protection. Should a problem occur, the controller triggers an
alarm and the compressor is stopped if necessary.

TEMPERATURE SENSORS — The system uses electronic
sensors to measure and control the temperatures in the unit.
There are three types of temperature sensors: 5K thermistor,
10K thermistor, and RTD (resistance temperature detector,
100 , 3-wire) based on IOB channel configurations. The temperature sensor range is –40 F (–40 C) to 245 F (118 C). See
Table 7.

screen interface or by connecting to a web interface at the
Ethernet IP port of the controller. The navigation menus are the
same for both connection methods.

PIC 5 CONTROL OPERATION
Start-Stop Control — This function controls the chiller
START-STOP command. There are four selectable control
modes: LOCAL, LOCAL SCHEDULE, REMOTE, or NETWORK. See Unit Start/Stop Screen on page 18. Specific control sources are valid to start or stop the chiller for each control
mode.
LOCAL — When the control mode is LOCAL, the chiller can
be started by the “Local ON” button on the PIC 5 interface
screen, and can be shut down by the Confirm Stop button on
the screen or by the EMSTOP software point.
LOCAL SCHEDULE — When the control mode is LOCAL
SCHEDULE, the chiller will be started automatically if the
configurable local schedule is Occupied. The chiller can be
shut down by the unoccupied schedule, the Stop button on the
PIC 5 interface screen, or by the EMSTOP software point.
REMOTE — When the control mode is REMOTE, the chiller
will be started by the remote discrete input (REM_CON) located on the I/O board. The chiller can be shut down by the remote discrete input, the Stop button on the PIC 5 interface
screen, or by the EMSTOP software point.
NETWORK — When the control mode is NETWORK, the
chiller can be started and stopped by the CHIL_S_S and
CHIL_OCC software points, which are written by other equipment through network commands and network schedule. The
chiller can also be shut down by the EMSTOP software point.
NOTE: There is a STOP OVERRIDE point in the GENUNIT
table. If this point is enabled the chiller cannot be started and
will shut down the chiller if it is running.
Chiller Start-Up Sequence
PRE-START CHECK — Once start-up begins, the controller
performs a series of pre-start tests to verify that all pre-start
alerts and safeties are within limits. Progress is shown on the
Startup Sequence screen (see Fig. 34). Table 11 lists pre-start
alert and alarm conditions.

The control then waits until the oil pressure (OIL PRESS
VERIFY TIME, operator-configured, default 40 seconds)
reaches a maximum of 18 psi (124 kPa). After oil pressure is
verified, the control waits 40 seconds for oil prelube, and the
compressor start relay energizes to start the compressor.

Chiller Shutdown Sequence — Chiller shutdown
begins if any of the following occurs:
• Local OFF button is pressed
• A recycle condition is present (see the previous section)
• The time schedule has gone into unoccupied mode
• The chiller protective limit has been reached and chiller
is in alarm
• The start/stop status (CHIL_S_S) is overridden to stop
from the network
If the chiller is normally shut down from running, a softstop shutdown will be performed. The soft-stop feature closes
the guide vanes of the compressor automatically if a non-alarm
stop signal occurs before the compressor motor is deenergized.
Any time the compressor is directed to STOP (except in the
cases of a fault shutdown), the guide vanes are directed to close
and VFD will be commanded to minimum speed for a variable
speed compressor. The compressor shuts off when any of the
following is true:
• AVERAGE LINE CURRENT (%) drops below the
SOFT STOP AMPS THRESHOLD
• ACTUAL GUIDE VANE POSITION drops below 4%
• Four minutes have elapsed since the stop was initialized
When any of these conditions is true, the shutdown sequence stops the compressor by deactivating the compressor
start relay. The guide vanes are then commanded to the fully
closed position. The oil pump relay will be turned off after 60
seconds post-lube.
Finally, the chilled water/brine pump and condenser water
pump are shut down.
*Evap trip point = 33 F (0.6 C) (water) or EVAP REFRIG TRIPPOINT
(brine).
The compressor RUN STATUS parameter on the default
screen line now reads PRESTART. If a test is not successful,
the start-up is delayed or aborted. If the tests are successful, the
chilled water pump relay energizes, and the main screen line
now reads STARTUP.
START-UP — One second after the successful pre-start check,
the chilled water and condenser water pump relays are energized.
Five seconds later, the control monitors the chilled water
and condenser water flow devices and waits until the WATER
FLOW VERIFY TIME (service-configured, default 5 minutes)
expires to confirm water flow.
After water flow is verified, the water temperature is compared to CONTROL POINT + 1/2 CHILLED WATER DEADBAND. If the temperature is less than or equal to this value, the
control turns off the condenser pump relay and goes into RECYCLE mode.
If the RECYCLE condition does not exist, the start-up sequence continues and checks the guide vane position. For a single-stage compressor (Comp [Single = 0, Dual = 1] = 0 in
FACTORY configuration), if the guide vanes are more than
4% open, the start-up waits until the controller closes the vanes.
For a dual-stage compressor (Comp [Single = 0, Dual = 1] = 1
in FACTORY configuration), the guide vanes are opened to the
initial position specified with GV1 Closure at Startup in the
Option Configuration menu.
If an HGBP or economizer damper valve is equipped and
enabled, the control checks that the position of these valves is
fully closed.
If the vanes and valves position are verified and the oil
pump pressure is less than 4 psi (27.6 kPa), the oil pump relay
is energized.
Oil Lubrication Control — As part of the pre-start
checks executed by the controls, the oil sump temp is compared to the evaporator saturated refrigerant temperature. If the
oil temperature is less than 140 F (60 C) and less than evaporator saturated refrigerant temperature plus 50° F (27.8° C), the
start-up will be delayed until either of these conditions is no
longer true. Once this temperature is confirmed, the start-up
continues.
The oil heater relay is energized whenever the chiller compressor is off and the oil sump temperature is less than 140 F
(60 C) or the oil sump temperature is less than the evaporator
saturated refrigerant temperature plus 53° F (29.4° C). The oil
heater is turned off when either of the following conditions is
true:
• Oil sump temperature is more than 152 F (66.7 C)
• Oil sump temperature is more than 144° F (62.2 C) and
more than the evaporator saturated refrigerant temperature plus 55° F (30.6° C).
The oil heater is always off when the compressor is running.
The oil pump is also energized for 30 seconds after each 30
minutes of the oil heat relay being energized in order to stir the
oil for more evenly distributed heating.
Control Points
SET POINT — The set point can be configured at the Setpoint
menu (“USER” access level).
The set point is determined by the heat/cool mode, EWT
22
POSITION if it has not reached the travel limit; if the travel
limit has been reached, the control increases VFD TARGET
SPEED. If decreased capacity is needed, the control first tries
to decrease VFD TARGET SPEED if it has not reached the
minimum VFD speed; if the minimum VFD speed has been
reached, the control decreases IGV TARGET POSITION instead. See Fig. 35.
From the compressor relay closed point to the end of ramp
loading, the VFD TARGET SPEED is the configured VFD
start-up speed. When the chiller is running normally, the capacity control determines whether and how much to change VFD
TARGET SPEED. When the chiller is in the shut-down process, VFD TARGET SPEED will be the minimum VFD speed.
NOTE: If the VFD option is set to NO VFD, or the compressor
relay is not closed, VFD TARGET SPEED will be 0.
The guide vane position is determined by the Capacity Control function under normal conditions and other functions in
abnormal conditions, which include capacity inhibit request or
capacity decrease request. The guide vane actuator is driven by
comparing the guide vane target position and the actual position. The guide vane actual position can be viewed on the default screen, and ranges from zero to the guide vane travel limit
configured from the Service Configuration menu. When the
chiller is shutting down or off, the guide vane is always driven
to zero.
RAMP LOADING — The ramp loading control slows the
rate at which the compressor loads up. This control can prevent
the compressor from loading up during the short period of time
when the chiller is started and the chilled water loop has to be
brought down to CONTROL POINT (Setpoint Table). Ramp
loading helps reduce electrical demand charges by slowly
bringing the chilled water to CONTROL POINT. The total
power draw during this period remains almost unchanged.
Two methods of ramp loading are available: temperature
ramp loading and motor load ramp loading.
Temperature Ramp Loading — Temperature ramp loading
limits the rate at which the controlled water temperature decreases for cooling and increases for heating during ramping by
reducing on cooling mode or increasing in heating mode the
PULLDOWN SET POINT (Maintenance Menu  Capacity)
at the configured rate, until the pulldown set point is less than
the cooling mode control point or greater than the heating
mode control point. The PULLDOWN RAMP TYPE (Configuration Menu  General Configuration) is configured to 0 for
temperature ramp loading.
Motor Load Ramp Loading — Motor load ramp loading limits the rate at which either the line current percentage or motor
kilowatt percentage increases by incrementing the ramp demand limit at the configured rate. The PULLDOWN RAMP
TYPE (Configuration Menu  General Configuration) is configured to 1 for motor load ramp loading.
If DEMAND LIMIT SOURCE (Configuration Menu 
General Configuration) is set to AMPS, then PERCENT LINE
CURRENT is used for motor load ramp loading. If DEMAND
LIMIT SOURCE is set to kW, then MOTOR PERCENT
KILOWATTS is used for motor load ramp loading.
The motor load ramp loading algorithm shall be deactivated
when the Ramp Demand Limit is greater than or equal to the
ACTIVE DEMAND LIMIT (General Parameters). It is also
deactivated when Ramp Demand Limit is greater than or equal
to 60%. There will be a one-minute delay for the compressor to
be uploaded to target load (ramping load target 60%) after
ramping load demand limit is set to 60%.

CONTROL POINT TEMPERATURE — Capacity control is
based on achieving and maintaining a control point temperature, which is the sum of a valid set point (from the SETPOINT
screen) and a temperature reset value. In Cooling mode, the
control point temperature is equal to the set point plus temperature reset. In Heating mode, the control point temperature is
equal to the set point minus temperature reset.
The control point can be viewed directly on the main screen
or the General Parameters menu.
TEMPERATURE RESET — Three types of chilled water or
brine reset are available and can be viewed or modified on the
Reset Configuration screen.
The default screen indicates when the chilled water reset is
active. The control point Reset on the General Parameters
screen indicates the amount of reset.
To activate a reset type, access the Reset Configuration
(RESETCFG) screen and input all configuration information
for that reset type.
Reset Type 1: 4 to 20 mA Temperature Reset — Reset Type
1 is an automatic reset utilizing a 4 to 20 mA analog input signal provided from any external sensor, controller, or other device which is appropriately configured. For this type, Degrees
Reset At 20 mA is configured in the RESETCFG table.
Reset Type 2: Remote Temperature Reset — Reset Type 2 is
an automatic water temperature reset based on a remote temperature sensor input signal. This function can be accessed by
setting the following configurations:
1. Configure the remote temperature at which no reset occurs (Remote temp  NO RESET).
2. Configure the remote temperature at which full reset occurs (Remote temp  FULL RESET).
3. Enter the amount of reset (Deg Reset Water DT Full).
Reset Type 3: Controlled Water Temp Delta Reset — Reset
Type 3 is an automatic controlled water temperature reset
based on heat exchanger temperature difference. This function
can be accessed by setting the following configurations:
1. Configure the controlled water temperature delta T at
which no reset occurs (Controlled Water DELTA T 
NO RESET).
2. Configure the controlled water temperature delta T at
which full reset occurs (Controlled Water DELTA T 
FULL RESET).
3. Enter the amount of reset (Deg Reset Water DT Full).
CAPACITY CONTROL — Capacity control provides chilled
or condenser water temperature control by modulating the position of the inlet guide vane 1, and VFD speed for variable
speed compressors.

CURRENT / 10]), an incidence of surge has occurred, and the
surge protection signal will be sent.
When an incidence of surge determined in this manner has
occurred, the SURGE COUNTS will be incremented by one.
On receiving the surge protection signal, Capacity Control will
make corrections on IGV1 TARGET POSITION, VFD TARGET SPEED, and HGBP actuator. When correction is in effect, Surge Protection Count will be added every 10 seconds. If
IGV, VFD and HGBP cannot be corrected, chiller will send a
shutdown alarm when the surge count is greater than 4.
HOT GAS BYPASS (HGBP) CONTROL — The hot gas
bypass function is used to artificially load the chiller and keep
it running under low load conditions or to prevent surge conditions. Since this also reduces the performance of the machine,
HGBP Control is a user-selectable option.
Hot gas bypass operation has three different modes when
installed (hgbp_opt = 1) and enabled (hgbp_sel > 0):
• Hot gas bypass for surge correction — Each compressor
has unique lift characteristics that can be plotted to determine performance. The controller will determine operating conditions that could result in compressor surge and
activate the hot gas bypass valve to prevent surge until
the chiller operating parameters are in a safe area on the
curve where the valve may be closed again.
• Hot gas bypass for low load operation — In this condition, the hot gas bypass valve will be opened to prevent a
recycle shutdown from occurring. The hot gas bypass
valve will remain open until this minimal loading condition has passed and there is no surge condition present.
• Combination surge correction and low load operation —
When this option is selected, both HGBP for surge prevention and HGBP for low load operation will be performed. Surge prevention will take higher priority if both
conditions are satisfied.
SURGE CORRECTION CONTROL — There are two stages for surge correction: envelope control (surge prevention)
and surge protection.
Envelope Control — A surge condition occurs when the lift
becomes so high that the gas flow across the impeller reverses.
This condition can eventually cause compressor damage. The
surge prevention algorithm notifies the operator that chiller operating conditions are marginal and to take action, such as lowering entering condenser water temperature, to help prevent
compressor damage.
If a high sound condition occurs at low guide vane position,
the HGBP valve is used to decrease the sound level. The envelope control algorithm is an operator-configurable feature that
can determine if lift conditions are too high for the compressor
and then take corrective action. High efficiency mode or low
noise mode can be selected. Lift is defined as the difference between the saturated temperature at the impeller eye and at the
impeller discharge. The maximum lift a particular impeller
wheel can perform varies with the gas flow across the impeller
and the size of the wheel.
If Actual Lift is higher than reference lift, a capacity inhibit
signal will be sent. If Actual Lift is higher than reference lift
plus Surge Line High Offset, a capacity decrease signal will be
sent. If Actual Lift is lower than reference lift minus Surge
Deadband, these 2 signals will be canceled. Capacity Control
will respond to these 2 signals and make correction on IGV1
TARGET POSITION, VFD TARGET SPEED, and HGBP actuator.
Surge Protection — The Surge Protection algorithm will run
after SURGE DELAY TIME has elapsed when compressor
has been commanded to turn on. It compares the present PERCENT LINE CURRENT value with the previous value once
every second. If the difference exceeds the maximum AMPS
change value (SURGE DELTA % AMPS + [PERCENT LINE
24
value 100%). ACTIVE DEMAND LIMIT may also be forced
to be different from BASE DEMAND LIMIT by manually
overriding (forcing) the value via a CCN network device. If
the DEMAND LIMIT SOURCE exceeds the ACTIVE DEMAND LIMIT by 5% or less, capacity will be inhibited. If the
DEMAND LIMIT SOURCE exceeds the ACTIVE DEMAND
LIMIT by more than 5%, capacity will be decreased.
Alternatively, the limit may be applied by by AUTO DEMAND LIMIT INPUT, an optional 4 to 20 mA input. This demand limit control option (4-20 mA DEMAND LIMIT TYPE)
is externally controlled by a 4 to 20 mA signal. The option is
set up on the Configuration Menu  GENERAL CONFIGURATION screen. When enabled, 4 mA will set ACTIVE DEMAND LIMIT to 100% of the DEMAND LIMIT SOURCE
(regardless of the value of BASE DEMAND LIMIT), and 20
mA will set ACTIVE DEMAND LIMIT to the value configured for DEMAND LIMIT AT 20 mA in the Configuration

OVERRIDE CONTROL — Capacity overrides can prevent
some safety shutdowns caused by exceeding the motor amperage limit, evaporator refrigerant low temperature safety limit,
motor high temperature safety limit, and condenser high pressure limit. In these cases there are two stages of capacity control:
1. When the value of interest crosses the first stage set point
into the override region, the capacity is prevented from
increasing further, and the status line on the PIC 5 controller indicates the reason for the override. Normal capacity control operation is restored when the value crosses back over the first stage set point, leaving the override
region.
2. When the value of interest is in the override region and
further crosses the second stage set point, the capacity is
decreased until the value meets the override termination
condition. The PIC 5 controls resume normal capacity
control operation after the override termination condition
has been satisfied. (In the case of high discharge superheat, there is an intermediate stage.)
Table 14 summarizes these override parameters.
ECONOMIZER DAMPER VALVE CONTROL —
The
economizer damper valve control maintains the difference between evaporator pressure and economizer pressure. Economizer pressure should always be higher than evaporator pressure.
NOTE: If the Chiller Type (Configuration Menu  Factory
Parameters) is configured to Legacy, the economizer damper
valve control is bypassed.
When the chiller is initially powered on, or when the compressor shuts down, the damper valve will be commanded to
close. These and other conditions are shown in Table 13.

If the damper valve has been commanded to open for a continuous 5 minutes, and the Damper Valve Full Opened condition is still not TRUE, the control system generates an alert
154. Similarly, if the damper valve has been commanded to
close for a continuous 5 minutes, and the Damper Valve Full
Closed condition is still not TRUE, the control system generates an alert 154.
If the compressor is running and if economizer pressure becomes less than or equal to evaporator pressure, an alarm 268
will be tripped and compressor will be shut down.
DEMAND LIMIT — The PIC 5 controls provide a feature for
limiting AVERAGE LINE CURRENT or MOTOR KILOWATTS by limiting capacity via guide vane control/VFD control. The limit may be applied in two ways. The first is called
ACTIVE DEMAND LIMIT, which is equal to a BASE DEMAND LIMIT value (set in the SETPOINT screen, default

at any time. If the controller is replaced, one opportunity before
the first start-up with the new controller is provided to set
COMPRESSOR ONTIME and TOTAL COMPRESSOR
STARTS to the last readings retained with the prior controller.
The chiller also maintains a start-to-start timer and a stopto-start timer. These timers limit how soon the chiller can be
started and are displayed on the system overview (home) and
RUN TIMES screens. They can be configured in the Configuration Menu  GENERAL CONFIGURATION screen. They
must expire before the chiller starts. If the timers have not expired, the RUN STATUS parameter on the System Overview
(Home) and GENERAL PARAMETERS screen reads TIMEOUT.
WATER PUMPS CONTROL (FREEZE PREVENTION)
NOTE: In order to energize the chilled and condenser pump to
prevent evaporator and condenser tube freeze-up, the hydraulic
system should be enabled first (this can be configured in the
Configuation Menu  FACTORY PARAMETERS screen).
Evaporator Freeze Prevention —When the evaporator saturated refrigerant temperature or evaporator refrigerant temperature is less than the EVAP REFRIG TRIPPOINT + REFRIG
OVERRIDE DELTA T (configurable from 2° F to 5° F (1.1° C
to 2.8° C) in the Configuration Menu  PROTECTIVE LIMIT CONFIG screen), an OVERRIDE—LOW EVAP REFRIG
TEMP event will occur.
For any running status, Protective Limit Alarm State 261
will be displayed and the unit will shut down if either of the following conditions is true:
• Evaporator saturated refrigerant temperature or evaporator refrigerant temperature is equal to or less than the
EVAP REFRIG TRIPPOINT (33 F [0.6 C] for water,
(configurable for brine in Configuration Menu  PROTECTIVE LIMIT CONFIG screen) plus 1° F (0.56° C).
• Leaving chilled water temperature or entering chilled
water temperature is less than EVAP REFRIG TRIPPOINT plus 1° F (0.56° C).
NOTE: If the chiller is in recycle mode, it will transition to
TRIPOUT, and the CHILLED WATER PUMP will remain on.
The alarm will be clearable when the evaporator saturated
refrigerant temperature, evaporator refrigerant temperature,
leaving chilled water temperature, and entering chilled water
temperature rise 5° F (2.8° C) above the EVAP REFRIG TRIPPOINT.
Condenser Pump Control —The chiller will monitor the condenser pressure and may turn on the condenser pump. If the
condenser pressure is greater than or equal to the COND
PRESS OVERRIDE, and the entering condenser water temperature is less than 115 F (46.1 C), the condenser pump will
energize to try to decrease the pressure and alert 157 will be
generated. The pump will turn off when the condenser pressure
is 3.5 psi (24.1 kPa) less than the pressure override and the condenser refrigerant temperature) is less than or equal to the entering condenser water temperature plus 3° F (1.7° C).
NOTE: COND PRESS OVERRIDE is found in the Configuration Menu  PROTECTIVE LIMIT CONFIG screen. The
default value is 140 psig (965 kPa) for low pressure condenser
and 250 psig (1724 kPa) for high pressure condenser.
Condenser Freeze Prevention — This control helps prevent
condenser tube freezing by energizing the condenser pump relay. The PIC 5 module controls the pump and, by starting it,
helps to prevent the water in the condenser from freezing.
When the chiller is off and condenser saturated refrigerant
temperature is less than or equal to the condenser freeze point,
the condenser water pump will be energized (Alarm State 262,
PROTECTIVE LIMIT - CONDENSER FREEZE). The fault
state will clear and the pump will turn off when the condenser
saturated refrigerant temperature is more than 5° F (2.7° C)
above the condenser freeze point and the entering condenser
Other types of override events do not override control guide
vane or VFD operation, but are reported:
• High compressor discharge temperature override — If
the COMP DISCHARGE TEMP is greater than the
COMP DISCHARGE ALERT threshold, then high discharge temperature override will be displayed in the
main screen until the COMP DISCHARGE TEMP is less
than the COMP DISCHARGE ALERT threshold – 2° F
(1.1° C).
• High compressor bearing temperature override — If a
compressor bearing temperature is greater than the compressor bearing temperature Alert (Configuration Menu
 Protective Limit Config) threshold, then High Bearing
Temp Override shall be set to TRUE until all of the compressor bearing temperatures are less than Comp Bearing
Temp Alert minus 2° F (1.1° C).
RECYCLE CONTROL — The chiller may cycle off and wait
until the load increases to restart when the compressor is running in a lightly loaded condition. This normal cycling is
known as “recycle.”
In cooling mode, a recycle shutdown is initiated when either
of the following conditions is true:
• Leaving chilled water temperature (or entering chilled
water temperature, if the EWT CONTROL OPTION is
enabled) is more than 5° F (2.8° C) below the CONTROL POINT.
• Leaving chilled water temperature (or entering chilled
water temperature, if the EWT CONTROL OPTION is
enabled) is below the CONTROL POINT, and the chilled
water temperature difference is less than the RECYCLE
SHUTDOWN DELTA T.
In heating mode, a recycle cycle shutdown occurs when either of the following conditions is true:
• Leaving condenser water temperature (or entering condenser water temperature, if the EWT CONTROL
OPTION is enabled) is more than 5° F (2.8° C) below the
CONTROL POINT.
• Leaving condenser water temperature (or entering condenser water temperature, if the EWT CONTROL
OPTION is enabled) is above the CONTROL POINT,
and the condenser water temperature difference is less
than the RECYCLE SHUTDOWN DELTA T.
NOTE: Recycle shutdown will not occur if the CONTROL
POINT has been changed by more than 1° F (0.56° C) within
the previous 5 minutes of operation.
When the chiller is in RECYCLE mode, the chilled water
pump relay remains energized so the chilled water temperature
can be monitored for increasing load. The recycle control uses
RECYCLE RESTART DELTA T to check when the compressor should be restarted. In cooling mode, the compressor will
restart when the leaving chilled water temperature (or entering
chilled water temperature, if the EWT CONTROL OPTION is
enabled) is greater than the CONTROL POINT plus the RECYCLE RESTART DELTA T for 5 consecutive seconds. In
heating mode, the compressor will restart when the leaving
condenser water temperature (or entering condenser water temperature, if the EWT CONTROL OPTION is enabled) is less
than the CONTROL POINT minus the RECYCLE RESTART
DELTA T for 5 consecutive seconds.
RUNNING TIMERS AND COUNTERS — The PIC 5 control maintains two run-time clocks: COMPRESSOR ONTIME
and SERVICE ONTIME. COMPRESSOR ONTIME indicates
the total lifetime compressor run hours. SERVICE ONTIME is
a resettable timer that can be used to indicate the hours since
the last service visit or any other event. A separate counter tallies compressor starts as TOTAL COMPRESSOR STARTS.
All of these can be viewed on the RUN TIMES screen. Both
Ontime counters roll over to 0 at 500,000 hours. Manual
changes to SERVICE ONTIME from the screen are permitted
26
PIC5 control system to allow PIC5 control for the water pumps
and cooling tower fans (high speed and low speed).
The cooling tower fans are controlled by the pressure difference between condenser and evaporator and entering water
temperature of condenser. The objective is to maintain the entering condenser water temperature in the optimal range.
HEAD PRESSURE CONTROL — If the chiller system is
equipped with a head pressure control valve, and the HEAD
PRESSURE VALVE option in the CONF_OPT table is ENABLED, the PIC5 control system will control the opening of
the head pressure valve to maintain the pressure difference between condenser and evaporator. The output of this valve is 4
to 20 mA type.
Before using this function, the pressure difference values for
20 mA and 4 mA should be set.
The head pressure valve should be in fully closed position
when chiller is in OFF mode.
ICE BUILD OPTION — The PIC5 controller provides an ice
build option based on efficiency improving point. The ICE
BUILD OPTION in the CONF_OPT table should be set to
ENABLED to make ice build active, and the following two parameters should be configured:
• Ice_recy (ICE BUILD RECYCLE) indicates whether
recycle option is enabled in ice build mode.
• Ice_term (ICE BUILD TERMIN SOURCE) indicates
how the ice build is terminated. There are three types:
temperature (0), dry contact (1), or combined temperature and dry contact (2).
TIME SCHEDULE — The PIC 5 control provides three
schedules:
• Local schedule - OCCPC01S
• Ice build schedule - OCCPC02S
• Network schedule - OCCPC03S
Each schedule has 8 time segments. If two time segments
overlap, the unoccupied time segment takes priority.
There are 16 holiday time segments. Each holiday time segment is determined by three parameters—month, start date,
and holiday days. The controller will be in unoccupied mode
when a holiday time segment is active.
BLACK BOX — The black box task continuously stores
operation parameters in memory every 5 seconds. Up to 20
collects can be stored before a chiller operation alarm event to
avoid filling the buffer unnecessarily. Each collect contains up
to 180 records (15 minutes), with 168 records (14 minutes)
before the alarm event and 12 records (1 minute) after the
event. The black box task uses the “rotary” rule to fill the
records in the buffer (first in first out). Each record is associated with a time in hour, minute, and second. When 12 records
have been collected after the process alarm event, the black
box task stops the collect, transfers the information into a .csv
file, and starts to fill another event record. The RAM memory
writing is never stopped, so if another alarm event occurs there
is no data loss. (If power is lost, only the .csv files remain. Data
in RAM memory is lost.)
The black box file can be uploaded with the Carrier S-Service tool. Once the upload is done, the data collect erase flag
will be sent from the Carrier S-Service and the collect buffer
will be erased.
PRESSURE TRANSDUCER CALIBRATION — The HMI
pressure readings are displayed in the Main Menu  Pressures
screen. See Fig. 36 and 37.
water temperature is greater than the condenser freeze point. If
the chiller is in recycle shutdown mode when the condition occurs, the controls will transition to a non-recycle shutdown.
CONTROL TEST — This feature allows the operator to
quick-test the controls and related hardware, including all unitcontrolled outputs except compressor output.
The unit must be off to run the test function. If the unit is on,
the test function cannot be accessed. The compressor can only
be started after the control test is finished (QCK_TEST =
FALSE). The test function also requires the user to enter the
User password if it has not already been entered. All control
test parameters are accessible through the QCK_TEST table.
To perform the control test function, set the first item Quick
Test Enable in the QCK_TST table to Enable.
Unless otherwise noted, all protective limits remain active
during the controls test.
Discrete Outputs — When the control test is enabled, discrete
outputs can be enabled by setting the corresponding points to
Yes in the QCK_TST table.
NOTE: The following outputs cannot be enabled at the same
time Guide Vane Increase and Guide Vane Decrease are
enabled: HGBP Valve Open and HGBP Valve Close; Economizer Damper Valve Open and Economizer Damper Valve
Close.
NOTE: For oil pressure, a value  18 psi within 40 seconds
after the oil pump is turned on indicates a confirmation of pressure (Oil Pres Test Passed=YES).
Analog Output — When the control test is enabled, the following analog outputs can be enabled by entering the positions
in the QCK_TST table:
• Head Pressure Valve
• Diffuser Actuator
• Chiller Status Output (Q_CHST)
Guide Vane Calibration — The guide vane position should be
calibrated before starting the chiller. Guide vane calibration
can be started by setting Quick Test Enable to Enable and GV1
Calibration Enable to Enable.
If the actuator type is digital (POS) 0, then:
• The fully closed guide vane feedback resistance will be
in the range of 62.5 ohms to 688 ohms (350 ± 75 ohms
target setting).
• The fully opened guide vane feedback resistance will be
in the range of 6190 ohms to 11,496 ohms (10,000 ohms
target setting).
If the actuator type is analog (1):
• The fully closed guide vane feedback mA value will be
in the range of 3 mA to 5 mA.
• The fully opened guide vane feedback mA value will be
in the range of 19 mA to 20.8 mA.
SWIFT RESTART — This function is used for data center applications. It allows the chiller to be restarted swiftly to meet
building load requirements.
To enable this function, the AUTO RESTART OPTION
point in the CONF_OPT table should be set to ENABLE.
The water flow verification time, oil prelube time and other
delays will be decreased accordingly. If the control system and
oil system are equipped with UPS (uninterrupted power supply), the start-up time will be decreased accordingly.
COOLING TOWER CONTROL — If WATER PRESSURE OPTION in the CONF_OPT table is set to ENABLED,
there will be another optional hydraulic control I/O board in the

Once a year the pressure transducers should be checked
against a pressure gage. Attach a set of accurate refrigeration
gages to the tranducer being checked and compare the two
readings. If there is a difference the transducer can be calibrated as described below (the Oil Pump Delta P reading should be
zero when the compressor is off). Calibration requires Service
level access to the HMI.
NOTE: It is usually not necessary to calibrate at initial start-up
unless chiller is at high altitude.

3. With the transducer at atmospheric pressure (zero gage
pressure), ensure that “Calib Press1 (0 PSI)” = 0 PSIG.
4. Pressurize the transducer to a known pressure between
100 and 250 psig, and enter that known pressure in the
“Calib Press2 (100-250PSI)” field.
5. Set Calibration Enable to Enable.
Calibration for this sensor is complete and the new slope
and intercept will be used for the calibrated transducer in
the pressure or temperature tables.
ALARM EMAIL — The alarm email function sends automatic email messages to specified service personnel for remote
maintenance purposes. Use the service configuration table

The following functions are available if the Prog Function
Enable option is set to YES (prog_en=YES):
Oil Change Notification — The lubrication oil should be
changed periodically in order to keep the appropriate lubrication for the motor and compressor. Once the period set in the
Oil Change Duration field is expired, a statement is displayed
to warn the user “to replace the oil charge or confirm the additive level is adequate and has not depleted.” After correction
items have been finished, set the Oil Charge Completed option
to YES manually.
29
Oil Filter Alert — This function is active only in an oil pump
control test. If the oil pump is forced to ON and after 10 seconds, if the pressure differential between oil pump pressure
and oil discharge pressure is lower than the threshold set in the
Oil Filter Pres Diff field, the filter needs to be replaced and the
dedicated alert 160 is reported until the oil pressure differential
is higher than the alert threshold plus 2 psig. Then set the Oil
Filter Change Done option to YES manually.
Refrigerant Transducer Calibration — When the unit is
offline for more than 5 minutes, a comparison is made of the
evaporator, condenser, and economizer refrigerant pressure
transducers. A difference of more than the configurable threshold set in the Trans Calib Threshold option generates an alert
161 that a calibration is required. The comparison is done for
all of the transducers. After calibration, set the Trans Calibration Done option to YES manually.
Low Refrigerant Charge — This function uses the evaporator approach (Evap Design Approach) setting and compressor
discharge temperature (Bearing Degradation) setting in relation to the condenser refrigerant temperature (Low Charge
Cond Approach) setting to generate an alert 162 of possible
low refrigerant charge. After correcting the charge, set the
Refrigerant Charge Done option to YES manually.
MASTER SLAVE CONTROL — This control, available
from page 2 of the Configuration Menu, provides the capability to operate 2 chillers in Master/Slave mode. The slave chiller
should be set to NETWORK mode and controlled by the master chiller.
The two chillers can be configured to be in parallel or in series. When they are in series mode, master and slave chillers
can be configured to be upstream or downstream. The master
chiller monitors all external commands, such as start/stop, demand limiting, or setpoint configuration.
The master/slave function provides the ability to select a
lead chiller from the master and the slave chillers. Selection is
based on the delta between the master and the slave run hours,
and tries to optimize the runtime hours. If this function is not
set, the lead chiller is always the master chiller and should be
changed to lag when it fails.
The lead chiller shall always be started first, and the lag
chiller shall be maintained at zero percent capacity. When the
lead chiller cannot be loaded anymore, then the lag start timer
is started. The lag chiller shall always be stopped first.
If a communication failure is detected between the master
and the slave chillers, all master/slave functions are disabled
and chillers return to stand-alone operations until communication is reestablished.

DIAGNOSTICS AND TROUBLESHOOTING
The 19XR PIC 5 control system has many fault tracing aid
functions. The local interface and its various menus give access
to all unit operating conditions.
If an operating fault is detected, an alarm is activated. The
alarm code is displayed in the Alarms menu, sub-menus Reset
alarms and Current alarms. The control may record up to 10
current alarms.
Displaying Alarms — The alarm icon on the interface
(see the section Icons on page 17) indicates unit status as follows:
• A flashing LED shows that the unit is operating but there
is an alert.
• A steady LED shows that the unit has been shut down
due to a fault.
The Reset Alarms option on the main menu displays up to
five alarm codes that are active on the unit. Table 15 lists alarm
codes. The Current Alarms option displays details for each
alarm.
Displaying Data Trends — The PIC 5 control system
offers the ability to configure and display system trends wiwthout a password. Select Main Menu  Trendings.
On the Trendings screen (see Fig. 47), check the data to be
tracked. Set the beginning and end points for the selected data.
To change a color, select the colored square and choose a new
color from the pop-up color bar. To view data trends, select the
down arrow at the bottom right of the Trendings screen. The
next page displays the selected data in the chosen colors. See
Fig. 48.
Resetting Alarms — When the cause of the alarm has
been identified and corrected, the alarm can be reset either automatically or manually (depending on the type of alarm).
Alarms can be reset without stopping the machine.
In the event of a power supply interrupt, if Auto Restart Option is set to ENABLE in the Option Configuration menu, the
unit restarts automatically without the need for an external
command. However, any faults active when the supply is interrupted are saved and in certain cases may prevent a unit from
restarting.
30
A manual reset must be run from the main menu via the
ALARMRST menu, item RST_ALM.
Once the alarm has been corrected or reset, all information
regarding solved alarms is stored in the Alarm History. See Appendix A, page 94.
Alert Codes — Table 16 lists PIC 5 alert codes. These are
automatically reset when the situation returns to normal.

In the example shown in Fig. 63, the PC receives four negative responses (request timed out).
Troubleshoot these with the following methods:
UNIT IS POINT-TO-POINT CONNECTED TO A PC —
The cable can be either crossed or uncrossed, and the unit is
energized.
NOTE: In addition to the following procedure, it may be necessary to check the Ethernet connection and/or configure the
PC network board.
In Network Settings, open Local Area Connection Properties. Select Internet Protocol and click Properties. See Fig. 61.
Ethernet/IP Connection Problems —

Fig. 63 — Ping — Negative Responses
If the PC receives four negative responses, check the internet browser parameters to determine if a proxy server or an automatic configuration script has been configured. If this is the
case:
• Deselect the proxy server or the configuration script and
restart the browser,
• Or refer to the section Java Application Configuration
(page 57).
Try to access the unit again. If the PC still does not receive a
response from the unit, restart the unit. Contact your system administrator.
UNIT IS CONNECTED TO THE LOCAL NETWORK —
The unit is connected to the local network by an uncrossed
cable, and the unit is energized. Open a Windows command
window (Start, Execute, type cmd and press Enter), then type
the command ping, followed by the unit IP address.
If the responses are positive (see Fig. 62), the internet
browser configuration is faulty. Check the system parameters
of the internet browser to determine if a proxy server or an automatic configuration script has been configured (Tools
Internet Options Connections System Parameters). See
Fig. 64.
SELECT
a30-5898
Fig. 61 — Local Area Connection Properties
The Internet Protocol Properties window is displayed.
• If no IP address is configured in the General and Alternative Configuration tabs, the unit IP address must be configured to 169.254.xxx.xxx. Modify the unit IP address
and then restart the system.
• If the PC has a fixed IP address configured in one of the
two tabs (General and Alternative Configuration), the IP
address of the PC and the unit IP address must have the
system and sub-system fields in common. The last part
of the IP address is the host number and must be unique
on the sub-system. For example: Unit address —
172.30.101.11 and PC address — 172.30.101.182. In this
example, 172.30 corresponds to the network, and 101
corresponds to the sub-system. Carry out the necessary
modifications and try to access the unit again.
If there is still a problem, open a Windows command window (Start, Execute, type cmd and press Enter), then type the
command ping, followed by the unit IP address. In the example shown in Fig. 62, the PC receives four positive responses
(replies).

If a configuration script is used, it is not possible to add the
unit IP address to the exceptions list. In this case, see the section Java Application Configuration below.
If the response to the “ping” command is negative, verify
the IP address of the PC and the IP address of the unit. They
must have the system network and sub-system in common.
The last part of the IP address is the host number and must be
unique on the sub-system; for example: Unit address —
172.30.101.11 and PC address — 172.30.101.182. In this
example, 172.30 corresponds to the system network, and
101 corresponds to the sub-system. The host numbers are 11
and 182 respectively.
ETHERNET CONNECTION ON THE PC — Open the
network configuration window of the PC and double-click
Network Connections. Find the system interface board and
check that no red “X” appears on the icon.
The connection to the local network must be authorized and
in the connected status. If this is not the case, check the connections and authorize/repair the network connection.
JAVA APPLICATION CONFIGURATION — Open the Internet configuration window of the PC and double-click the
Java application icon. If Java is not installed, a free download is
available at http://www.java.com.
If Java has already been installed, check if it is used by other
applications. If so, check that these are compatible with the following settings in the Java control panel. See Fig. 66.

APPENDIX C — INPUT/OUTPUT BOARD (IOB) STATUS INDICATORS
• Microprocessor operational and communicating with
control system: LED flashes at 0.5 Hz rate (1 second on,
1 second off) in sync (±100 ms) with all other new control modules on the same communication bus
• Microprocessor in boot mode: LED flashes at 0.2 seconds on, 0.2 seconds off)
Each independent communication port has a green status
LED. The green LED is on when data is being transmitted by
the board.
All control boards have LED indicators that show control
board and communication status.
A red LED on each control module operates in the following manner:
• Power not present or power supply failure: LED is off
• Power present but microprocessor in Reset: LED is off
• Microprocessor operational but not communicating:
LED flashes 3 seconds on, 3 seconds off
97
APPENDIX D — BACnet OPTION
General — The 19XR PIC 5 controller supports the BACnet protocol as B-ASC BACnet equipment over IP. In addition,
BACnet on the PIC 5 controller supports the following features:
• Optional properties such as Change of Value (COV),
Intrinsic Reporting, and Commandable properties on
some objects.
• The generation of limited alarm and event notifications
and the ability to direct them to recipients
• The tracking of acknowledgments of alarms from human
operators
• The adjustment of alarm parameters
• Read/write property for many services
Installing the BACnet Dongle — The BACnet op-
tion can be implemented at the factory or on-site. This section
is intended for on-site installation.
It is strongly recommended to disconnect the complete
power supply before any intervention. Disconnect the main
power supply with appropriate disconnect devices. Only personnel qualified to the level recommended in standard IEC
60364 (International Electrotechnical Commission) and trained
to do this may have access to electrical components.
a19-2262
Fig. I — Cover Removed
3. Insert the BACnet dongle into the connector. See Fig. J.
CAUTION
The components that make up the chiller controller include
electronic components. These may generate or be damaged
by electromagnetic interference such as electrostatic discharge (ESD).
Technicians who do not have access to an ESD wrist strap
on site should follow these recommendations in order to
minimize the risk of ESD:
• Be sure to be at zero potential by touching an
unpainted surface on the electrical box.
• Do not wear clothing that tends to conduct electrical
charge, such as a wool sweater.
• Electrical storms can increase the ESD risk; unless
absolutely necessary, do not work on the chiller controller during an electrical storm.
a19-2263
Fig. J — Inserting BAcNET Dongle
MOUNTING THE BACNET DONGLE — Follow these
steps to mount the BACnet dongle in the PIC 5 control box:
1. Disconnect the PIC 5 control power supply.
2. Open the metal cover of the control box with a screwdriver. See Fig. H and I.
4. Mount the plastic holder that holds the dongle to the
board. See Fig. K.

APPENDIX D — BACnet OPTION (cont)
Alarm states are coded as shown in Table B.
TESTING THE INSTALLATION — To verify that the dongle connection is correctly inserted and detected by the equipment, with the controller powered up, go to the PIC 5 Main
Menu nputs Status and confirm that the BACnet Dongle
status is Yes.
Table B — Alarm States
BACNET CODE

BACnet Settings — BACnet settings are available on
the Main Menu  Configuration Menu  BACnet Config.
The menu requires the Advanced User password for access.
For details, see the Bacnet Config table on page 79.
Modifying the Unit IP Address — Note that changing IP address from the PIC 5 SETUP menu will require a
manual reboot or power cycle of the PIC 5 controller in order
to re-build the BACnet stack. For detailed instructions, see the
Unit IP Address section on page 52.
BACnet Objects — The 19XR PIC 5 contains up to 500
BACnet objects. They can be of ANALOG_VALUE (AV) or
BINARY_VALUE (BV) type. Objects name are built from
CCN table name and CCN point name concatenated in order to
recognize them easily. For a detailed list, see the BACnet
Points table beginning on page 100.
In general, the equipment configuration parameters are
available as Read Only. Set point parameters are available in
Read-Write access.
Compressor status is ASCII-coded. In order to obtain the
status from BACnet, statuses are assigned a BACnet code as
shown in Table A.
BACnet IP Communication Problems — If the
unit does not respond to the building management system, possible causes include the following:
• The BACnet dongle is not detected by the chiller application.
• The Ethernet cable is not correctly connected.
• Network parameters are not correct (see the Ethernet/IP
Connection Problems section on page 56).
• There is an IP router between the equipment and the buildign management system.
• BACnet Enable parameter in the PIC 5 Configuration
Menu is set to No.
To troubleshoot problems, try these measures:
• Open the metal casing of the 19XR PIC 5 controller and
verify that the blue BACnet dongle is correctly connected.
• On the Ethernet connector, verify that the green LED is
ON and the orange LED is blinking
• Open a command window under Windows (Start, Execute, type cmd and press Enter), type the command ping
followed by the equipment IP address. The equipment
must respond.
• Open 19XR PIC 5 Configuration Menu (Service password required) and check BACnet parameters.
• Use the free software called BDT (BACnet Discovery
Tool) available on the internet (search bacnet bdt) and
install it on the PC. All equipment connected to the
BACnet network will respond to the “Who Is” command
sent by this tool. Find the equipment configured with the
BACnet device instance (1600001 for Carrier equipment).
