TechView is designed to run on a  
customers laptop, which connects to  
DynaView with a serial cable.  
DynaViews serial port is located  
behind a sliding door on the bottom of  
the DynaView enclosure. It uses a  
standard 9-pin male and 9-pin female  
RS-232 cable.  
Serviceability  
TechView™  
PreviousTrane chiller controllers  
included a user interface that presented  
all chiller data necessary for both daily  
tasks and service or maintenance tasks.  
The amount of information presented  
on a limited display made a number of  
tasks difficult. A service technician’s  
ability to assess and resolve chiller  
problems was hampered by the limited  
presentation of multiple pieces of  
chiller information.  
All chiller status, machine configuration  
settings, customizable limits, and up to  
60 active or historic diagnostics are  
displayed through the service-tool  
software interface. Any PC that meets  
the system requirements may  
download the service interface  
software and DynaView updates from  
Hardware requirements forTechView:  
• Pentium II, III, or higher processor  
• 128 MB RAM  
• 1024 x 768 resolution  
• CD-ROM  
TheTracer chiller controller adds a level  
of sophistication better served by a PC  
application that improves service  
technician effectiveness and minimizes  
chiller downtime. The Tracer chiller  
controller provides a user interface and  
main processor, DynaView, that is  
intended to serve only typical daily  
tasks. The portable, PC-based service  
tool software,TechView, supports  
service and maintenance tasks.  
• 56K modem  
• 9-pin RS232 serial connection  
• Windows® 95, 98, 2000  
TheTracer chiller controller will be  
gradually applied to allTrane chillers.  
TechView will then serve as a common  
interface to allTrane chillers, and will  
customize itself based on the  
properties of the chiller with which it is  
communicating. Thus, the service  
technician learns only one service  
interface.  
The panel bus is easy to troubleshoot,  
using LED verification of sensors. Only  
the defective device is replaced.  
Captive screws ensure that the  
appropriate mounting hardware is  
available.TechView can communicate  
with individual devices or groups of  
devices.

Benefits  
Time of day scheduling: allows the  
end user to define the occupancy  
period, i.e. time of the day, holiday  
periods and exception schedules.  
Feedforward Adaptive  
Control  
TheTracer chiller controller allows the  
system designer to explore energy  
saving strategies and allows the  
centrifugal chiller to be used in ways  
that were never thought possible.  
Building Automation and  
Chiller Plant Control  
For a preprogrammable and flexible  
building automation and chiller plant  
control,Trane has developed theTracer  
Summit. It can control the operation  
of the complete installation: chillers,  
pumps, cooling towers, isolating  
valves, air handlers and terminal units.  
Trane can undertake full responsibility  
for an optimized automation and  
energy management for the entire  
chiller plant.  
Optimization of the start/stop time of  
the installation: based on the  
programmed schedule of occupancy  
and on the historical record of the  
behavior of the temperatures,  
calculates the optimal time of start  
and stop of the installation to get the  
best compromise between energy  
savings and comfort of the occupants.  
Feedforward Adaptive Control  
Feedforward is an open-loop,  
predictive control strategy designed to  
anticipate and compensate for load  
changes. It uses evaporator entering-  
water temperature as an indication of  
load change. This allows the controller  
to respond faster and maintain stable  
leaving-water temperatures.  
Soft loading: the soft loading function  
minimizes the number of chillers that  
are operated to satisfy the building  
morning pull down, thus preventing  
an overshoot of the actual capacity  
required. Unnecessary starts are  
avoided and the peak current demand  
is lowered.  
The main functions are:  
Chiller sequencing: equalizes the  
number of running hours of the  
chillers. Different control strategies are  
available depending on the  
Soft Loading  
The chiller controller uses soft loading  
except during manual operation. Large  
adjustments due to load or setpoint  
changes are made gradually,  
configuration of the installation.  
Control of the auxiliaries: includes  
input/output modules to control the  
operation of the various auxiliary  
equipments (water pumps, valves,  
cooling towers, etc.)  
preventing the compressor from  
cycling unnecessarily. It does this by  
internally filtering the setpoints to avoid  
reaching the differential-to-stop or the  
current limit. Soft loading applies to the  
leaving chilled-water temperature and  
current-limit setpoints.  
Multi-Objective Limit Arbitration  
There are many objectives that the  
controller must meet, but it cannot  
satisfy more than one objective at a  
time.Typically, the controllers primary  
objective is to maintain the evaporator  
leaving-water temperature.  
Whenever the controller senses that it  
can no longer meet its primary  
objective without triggering a  
protective shutdown, it focuses on the  
most critical secondary objective.  
When the secondary objective is no  
longer critical, the controller reverts to  
its primary objective.  
Fast Restart  
While the inlet guide vanes are closing,  
the controller will allow the centrifugal  
chiller to restart and going to a  
postlube operational mode. If the  
chiller shuts down on a nonlatching  
diagnostic, the diagnostic has 30–60  
seconds to clear itself and initiate a fast  
restart. This includes momentary  
power losses.

Features and  
Benefits  
The length of the resultant vector V is  
proportional to the kinetic energy  
available for conversion to static  
pressure in the volute. Consequently,  
for a given compressor,Vt is fixed and  
Vr varies with the cooling load. With the  
chiller unloading, the pressure  
differential between evaporator and  
condenser decreases. The compressor  
matches the new load and the lower  
“head” by closing the inlet guide  
vanes.  
Two-Stage Compressor  
Widens the Application  
Range  
Why Centrifugal Compressors Surge  
Centrifugal compressors produce their  
pressure differential (head) by  
converting the kinetic energy of the gas  
leaving the impeller into static  
pressure. The velocity of this gas is the  
result of two components:  
•The radial velocity component Vr,  
which is directly proportional to the  
refrigerant gas flow Q.  
• The tangential velocity component Vt,  
which is a function of both impeller  
diameter D and the rotational speed  
rpm.  
This reduces the gas flow it draws in  
and modifies its direction. Component  
Vr decreases accordingly, the vector  
diagram shifts and at some point, the  
balance of forces breaks down.  
As pressurized gas rushes backwards  
through the impeller, the pressure in  
the gas passages falls, allowing the  
compressor to restore the balance of  
forces. If the process repeats itself, the  
compressor is said to surge.

6 - Q  
Two-Stage Compressors Surge Less  
and Later  
1 - Load Line  
2 - Surge Line  
3 - A  
To produce the same head as a single-  
stage compressor, two-stage machines  
use two small diameter impellers.  
Component Vt is the same as on each  
stage, thoughVr is the same as on a  
single-stage compressor.This results in  
a better balance of forces at low loads  
and produces a machine with a wider  
unloading capability.

InTrane centrifugal chillers, gas  
prerotation vanes ahead of the

aerodynamic efficiency, resulting in  
smoother unloading and reducing  
power consumption.  
Typical single-stage compressor  
performance curve  
The curves show that two-stage  
compressors surge less and later than  
single-stage machines. Intersection  
point B, when the load line meets the  
surge area, corresponds to a higher  
part load for the single-stage  
compressor than would be the case  
with a two-stage compressor.Two  
stage machines, therefore, have a  
wider range of applications.

Application  
Considerations  
Water Flow  
Condenser Water Limitations  
Todays technology challenges ARI’s  
traditional design of three gpm per ton  
through the condenser. Reduced  
condenser flows are a simple and  
effective way to reduce both first and  
operating costs for the entire chiller  
plant. This design strategy will require  
more effort from the chiller. But pump  
and tower savings will typically offset  
any penalty.This is especially true  
when the plant is partially loaded or  
condenser relief is available.  
Temperature  
Trane centrifugal chillers start and  
operate over a range of load conditions  
with controlled water temperatures.  
Reducing the condenser water  
temperature is an effective method of  
lowering the chiller power input.  
However, the effect of lowering the  
condenser water temperature may  
cause an increase in system power  
consumption.  
In many applicationsTrane centrifugal  
chillers can start and operate without  
control of the condenser water  
In new systems, the benefits can  
include dramatic savings with:  
• Size and cost for condenser lines and  
valves  
• Size and cost of the cooling tower.  
• Size and cost of the water pumps.  
• Pump energy (30 to 35% reduction).  
Tower fan energy(30 to 35%  
reduction).  
temperature. However, for optimum  
system power consumption, and for  
any applications with multiple chillers,  
control of the condenser water circuit is  
recommended. Integrated control of  
the chillers, pumps and towers is easily  
accomplished withTranes CH530 and/  
orTracer system.  
Replacement chiller plants can reap  
even greater benefits from low flow  
condensers. Because the water lines  
and tower are already in place, reduced  
flows would offer a tremendous energy  
advantage.Theoretically, a 2 GPM/ton  
design applied to a system that  
originally used 3 GPM/ton would offer  
a 70% reduction in pump energy. At the  
same time, the original tower would  
require a nozzle change but would then  
be able to produce about two degrees  
colder condenser water than before.  
These two benefits would again  
Chillers are designed to ARI conditions  
of 29.4°C (85°F), butTrane centrifugal  
chillers can operate to a five psig  
pressure differential between the  
condenser and evaporator at any  
steady state load without oil loss, oil  
return, motor cooling, refrigerant hang-  
up problems. And this differential can  
equate to safe minimum entering  
condenser water temperatures at or  
below 12.8°C (55°F), dependent on a  
variety of factors such as load, leaving  
evaporator temperature and  
typically offset any extra effort required  
by the chiller.  
component combinations. Start-up  
below this differential is possible as  
well, especially with CH530 soft start  
features  
Contact your localTrane Sales Office  
for information regarding optimum  
condenser water temperatures and  
flow rates for a specific application.  
Water Pumps  
Avoid specifying or using 3600 rpm  
condenser and chilled water pumps.  
Such pumps may operate with  
objectionable noises and vibrations. In  
addition, a low frequency beat may  
occur due to the slight difference in  
operating rpm between water pumps  
and centrifugal motors. Where noise  
and vibration-free operation are  
important, The Trane Company  
encourages the use of 1750 rpm  
pumps.  
Water Treatment  
The use of untreated or improperly  
treated water in a chiller may result in  
scaling, erosion, corrosion, algae or  
slime. It is recommended that the  
services of a qualified water treatment  
specialist be used to determine what  
treatment, if any, is advisable.The  
Trane Company assumes no  
responsibility for the results of  
untreated, or improperly treated water.

Chilled-Water Reset  
Chilled-water reset reduces energy  
consumption during periods of the  
year when heating loads are high and  
cooling loads are reduced. It is based  
on return chilled-water temperature.  
Resetting the chilled-water temperature  
reduces the amount of work that the  
compressor must do by increasing the  
evaporator refrigerant pressure. This  
increased evaporator pressure reduces  
the pressure differential the  
This includes all functions that start,  
run, and stop the motor.The starter  
module provides the interface and  
control ofY-delta, across-the-line,  
primary reactor, autotransformer, and  
solid-state starters. The motor control  
also provides protection to both the  
motor and the compressor.  
The field-connected elements are  
involved in physically turning the chiller  
on or off. This involves ensuring that  
the chiller is not in an emergency or  
external stop condition, starting the  
pumps, and verifying that flow has  
been established. The optional, factory-  
supplied flow switch or a

compressor must generate while in the  
heat recovery mode. Chilled-water  
reset is also used in combination with  
the hot-water control. By resetting the  
chilled-water temperature upward, the  
compressor can generate a higher  
condenser pressure, resulting in higher  
leaving hot-water temperatures.

necessary to control the chiller are

maintain the setpoint. Heating is the  
primary mission and cooling is a waste  
product or a secondary mission.  
This technique provides application  
flexibility, especially in multiple-chiller  
plants in conjunction with undersized  
heating plants.  
Extended Operation Package  
Select the extended-operation package  
for chillers that require external, hot  
water control, and/or base-loading  
capabilities. This package also includes  
a 4-20 mA or 0-10 Vdc analog input for  
a refrigerant monitor.  
• External base-loading control input  
• External base-loading setpoint  
• External hot-water control input  
• Refrigerant monitor input  
The chiller needs only one condenser  
for hot-water control, whereas Heat  
Recovery uses a secondary condenser.  
An alternative and less radical  
approach to Base Loading indirectly  
controls chiller capacity. Artificially  
load the chiller by setting the chilled-  
water setpoint lower than it is capable  
of achieving.Then, modify the chillers  
load by adjusting the current-limit  
setpoint. This approach provides  
greater safety and control stability  
because it leaves the chilled-water  
temperature-control logic in effect.  
The chilled-water temperature control  
responds more quickly to dramatic  
system changes and limits chiller  
loading prior to reaching an Adaptive  
Control limit.  
Refrigerant Monitor  
The Extended Operation package  
allows for a refrigerant monitor to send  
a 4-20 mA signal to the DynaView  
display. It can be calibrated to  
Base-Loading Control  
This feature allows an external  
controller to directly modulate the  
capacity of the chiller. It is typically used  
in applications where virtually infinite  
sources of evaporator load and  
condenser capacity are available and it  
is desirable to control the loading of the  
chiller.Two examples are industrial  
process applications and cogeneration  
plants. Industrial process applications  
might use this feature to impose a  
specific load on the facilitys electrical  
system. Cogeneration plants might use  
this feature to balance the systems  
heating, cooling, and electrical  
correspond to either 0-100 ppm or 0-  
1,000 ppm concentration levels.  
The concentration level is displayed at  
DynaView, but the chiller will not take  
any action based on the input from the  
refrigerant monitor.  
Alternatively, a refrigerant monitor can  
be connected toTracer Summit, which  
has the ability to increase ventilation in  
the equipment room in response to  
high refrigerant concentrations.  
Hot-Water Control  
This feature allows an external  
controller to enable/disable and  
modulate the hot-water control mode.  
Occasionally, centrifugal chillers are  
used to provide heating as a primary  
mission. In this case the external  
controller or operator would select a  
hot-water temperature setpoint and the  
chiller capacity would be modulated to  
generation.  
All chiller safeties and Adaptive Control  
functions are in full effect when Base  
Loading is enabled. If the chiller  
approaches full current, the evaporator  
temperature drops too low, or the

Evaporator Limit Protection  
Low Differential Oil-Pressure  
Protection  
Oil pressure is indicative of oil flow and  
active oil-pump operation. A significant  
drop in oil pressure indicates a failure  
of the oil pump, oil leakage, or other  
blockage in the oil-circuit.  
Evaporator Limit is a control algorithm  
that prevents the chiller tripping on its  
low refrigerant-temperature cutout. The  
machine may run up to the limit but  
not trip. Under these conditions the  
intended chilled-water setpoint may  
not be met, but the chiller will do as  
much as it can. The chiller will deliver  
as much cold water as possible even  
under adverse conditions.  
The chiller controller uses proportional-  
integral-derivative (PID) control for all  
limits—there is no dead band. This  
removes oscillation above and below  
setpoints and extends the capabilities  
of the chiller.  
The differential pressure during oil  
pump, compressor prelube mode  
should not fall below 12 psid. A failure  
on this parameter generates a shutdown  
diagnostic. When the compressor is  
running, a diagnostic is issued when  
the differential pressure is lost.  
Some of the standard protection  
features of the chiller controller are  
described in this section. There are  
additional protection features not listed  
here.  
Low Evaporator-Water Temperature  
Low evaporator-water temperature  
protection, also known as Freeze Stat  
protection, avoids water freezing in the  
evaporator by immediately shutting  
down the chiller and attempting to  
operate the chilled-water pump. This  
protection is somewhat redundant with  
the Evaporator Limit protection, and  
prevents freezing in the event of  
High Condenser-Pressure Protection  
The chiller controllers condenser limit  
keeps the condenser pressure under a  
specified maximum pressure. The  
chiller runs all the way up to 100  
percent of the setpoint before reducing  
capacity using its adaptive control  
mode.  
Phase-Unbalance Protection  
Phase-unbalance protection is based  
on an average of the three phase-  
current inputs. The ultimate  
phase-unbalance trip point is 30  
percent. In addition, the RLA of the  
motor is derated by resetting the active  
current-limit setpoint based on the  
current unbalance. The RLA derate  
protection can be disabled in the field-  
startup menu.  
extreme errors in the evaporator-  
refrigerant temperature sensor.  
Starter-Contactor Failure Protection  
The chiller will protect itself from a  
starter failure that prevents the  
compressor motor from disconnecting  
from the line to the limits of its  
capabilities.  
The cutout setting should be based on  
the percentage of antifreeze used in the  
customers water loop.The chillers  
operation and maintenance  
documentation provides the necessary  
information for percent antifreeze and  
suggests leaving-water temperature-  
cutout settings for a given chilled-water  
temperature setpoint.  
The following derates apply when the  
phase-unbalance limit is enabled:  
The controller starts and stops the  
chiller through the starter. If the starter  
malfunctions and does not disconnect  
the compressor motor from the line  
when requested, the controller will  
recognize the fault and attempt to  
protect the chiller by operating the  
evaporator-and condenser-water  
pumps and attempting to unload the  
compressor.  
10% unbalance = 100% RLA derate  
15% unbalance = 90% RLA derate  
20% unbalance = 85% RLA derate  
25% unbalance = 80% RLA derate  
30% unbalance = Shutdown  
Oil-Temperature Protection  
Phase-Loss Protection  
Low oil temperature when the oil  
pump and/or compressor are running  
may be an indication of refrigerant  
diluting the oil. If the oil temperature is  
at or below the low oil-temperature  
setpoint, the compressor is shut down  
on a latching diagnostic and cannot be  
started. The diagnostic is reported at  
the user interface. The oil heaters are  
energized in an attempt to raise the oil  
temperature above the low oil-  
The controller will shut down the chiller  
if any of the three phase currents  
feeding the motor drop below 10  
percent RLA. The shutdown will result  
in a latching phase-loss diagnostic. The  
time to trip is 1 second at minimum, 3  
seconds maximum.  
Loss of Water-Flow Protection  
The chiller controller has an input that  
will accept a contact closure from a  
proof-of-flow device such as a flow  
switch or pressure switch. Customer  
wiring diagrams also suggest that the  
flow switch be wired in series with the  
cooling-water (condenser-water) pump  
starters auxiliary contacts. When this  
input does not prove flow within a  
fixed time during the transition from  
Stop to Auto modes of the chiller, or if  
the flow is lost while the chiller is in the  
Auto mode of operation, the chiller will  
be inhibited from running by a  
Phase Reversal/Rotation Protection

rotation and provides a latching  
diagnostic when it is detected. The time

Surge Detection Protection  
Distribution Fault Protection  
Surge detection is based on current  
fluctuations in one of three phases. The  
default detection criterion is two  
occurrences of RMS current change of  
30 percent within 0.8 seconds in 60 + 10  
percent seconds. With theTracer  
chiller controller, the detection criterion  
is adjustable.  
Three-phase momentary power loss  
(MPL) detection gives the chiller  
• Line-voltage sags of 1.5 or more line  
cycles for voltage dips of 30 percent  
or more  
improved performance through many  
different power anomalies. MPLs of 2.5  
cycles or longer will be detected and  
cause the unit to shut down. The unit  
will be disconnected from the line  
within 6 line cycles of detection. If  
enabled, MPL protection will be active  
any time the compressor is running.  
MPL is not active on reduced-voltage  
starters from the initial start signal  
through transition. The MPL diagnostic  
is an automatic reset diagnostic. MPL  
protection can be disabled inTechView.  
• Control-voltage sags of 3 or more line  
cycles for voltage dips of 40 percent  
or more  
• Third-order or higher harmonic  
content on the line  
Overvoltage and Undervoltage  
Protection  
The unit will be shut down with an  
automatic reset if the line voltage is  
below or above 10 percent of nominal.  
Current Overload Protection  
The control panel will monitor the  
current drawn by each line of the motor  
and shut the chiller off when the  
highest of the three line currents  
exceeds the trip curve. A manual reset  
diagnostic describing the failure will be  
displayed. The current overload  
Must trip = 15 percent of nominal.  
Time to trip = minimum of 1 minute, 10  
seconds and maximum of 5 minutes,  
20 seconds. Overvoltage and  
undervoltage protection can be  
disabled using TechView.  
An MPL has occurred when the motor  
no longer consumes power. An MPL  
may be caused by any drop or sag in  
the voltage that results in a change in  
the direction of power flow. Different  
operating conditions, motor loads,  
motor size, inlet guide vane (IGV)  
position, etc. may result in different  
levels at which this may occur. It is  
difficult to define an exact voltage sag  
or voltage level at which a particular  
motor will no longer consume power,  
but we are able to make some general  
statements concerning MPL protection:  
protection does not prohibit the chiller  
from reaching its full-load amperage.  
Power Factor and kW Measurement  
Three-phase measurement of kW and  
unadjusted power factor yields higher  
accuracy during power imbalance  
conditions than with CH530.  
The chiller protects itself from damage  
due to current overload during starting  
and running modes, but is allowed to  
reach full-load amps.  
High Motor-Winding Temperature  
Protection  
Short-Cycling Protection  
Short-cycling protection is based on a  
start-to-start time. This method uses a  
straight start-to-start timer to determine  
when to allow the next start.  
This function monitors the motor  
temperature and terminates chiller  
operation when the temperature is  
excessive. The controller monitors each  
of the three winding-temperature  
sensors any time the controller is  
powered up, and displays each of the  
temperatures at the service menu.  
Immediately prior to start, and while  
running, the controller will generate a  
latching diagnostic if the winding  
temperature exceeds 265 5°F  
(129.4 2.8°C).  
The chiller will remain running under  
the following conditions:  
A ’Restart Inhibit Start-to-StartTime’  
setpoint is used to set the desired start-  
to-start time. There is no ’free’ start on  
a power up at DynaView.The real-time  
clock is used to determine when the  
next start will be allowed, based on the  
previous start.

When the start is inhibited by the  
restart-inhibit function, the time  
remaining is displayed along with the

The controller will load and unload the  
chiller via control of the stepper- motor/  
actuator which drives the inlet guide  
vanes open and closed. The load range  
can be limited either by a control limit  
function such as motor current, low  
evaporator temperature or high  
condenser pressure limit or by an inlet  
guide vane limit (whichever comes  
first). It will also control the evaporator  
and condenser pumps to insure proper  
chiller operation.
