Post-Conversion Checkout
Following are recommended checkout procedures for the converted starter
panel and newly-installed FastPak™ control panel.
Caution:
To prevent machine damage, contact a qualified service organization
to perform the checkout procedures described in this section.
Successful completion of these operational checks assures that the Fast
Pak panel is properly installed, that all required starter and chiller modifications are complete, and that the chiller is functioning normally.
An important aspect of the chiller maintenance program is the regular completion of records. Attached are copies of the:
-
• “Water Cooled Chillers with FastPak Commissioning Checklist & startup
Test Log”
“startup Test Log for Water Cooled Chillers with FastPak Control Panels”
•
• “FastPak Settings Group Menu Record”
It is recommended that these forms be used as it will assist with the startup
and in the future can be reviewed to identify any developing trends in the
chiller’s operating conditions.
1. Verify all wiring is connected correctly and numbered properly.
2. When all electrical connections are complete, close the main power
supply disconnect switch(es) to “power up” the control panel.
3. Setup and Calibrate the FastPak panel’s operating controls. See the
“Operation-Operator Interface” portion of this manual for assistance.
Note: Unit type must be setup as FastPak Water Cooled.
4. If installed, check and adjust the travel of the new stepper electric vane
actuator before connecting it to the guide vanes; to do this:
• Choose Inlet Guide Vane Output Type <Stepper Motor> from the
Machine Configuration menu and Vane Control <Manual> from the
Service Test menu. Verify that actuator operates from 0-100% (0-5"
stroke) open.
•
Connect the vane linkage to the actuator motor.
•
In the Field startup Service Setting Group, set the Inlet Guide Vane
(IGV) Maximum Travel Setpoint to the previously measured stroke (see
Actuator Mounting in the Installation Manual) X 10000 steps (i.e., a 5”
stroke equals 50000 steps).
•
In the Service Tests Group, change the vane control status to manual,
go to the next menu and increase vane position slowly until the vanes
are 100% open. If the vanes are not open, increase the IGV Maximum
Travel Setpoint by 1000 steps. Repeat this procedure as often as
necessary. The vane position will not correspond to the percentage
shown on the screen.
Caution:
The IGV actuator may go beyond the designed travel limits of the link
age. Failure to properly identify the fully open position can cause the
actuator to over travel and break the vane linkage.

IGV actuator steps is displayed. The number of steps should be
recorded and entered as the new IGV Maximum Travel Setpoint.
5. If the existing pulse actuator was reused, perform the following steps:
Choose Inlet Guide Vane Output Type <Pulsed> from the Machine
•
Configuration menu.
• In the Service Test menu, choose Manual Loading/Unloading Duty Cycle
<50%>.
Next, choose IGV Control <Load> or <Unload> in the Service Test
•
menu. Measure the cycle time (full open to full close or vice versa) in
seconds.
• Divide this number by two to obtain stroke time. Input this value at Inlet
Guide Vane Stroke Time in the Field startup menu.
6. Check purge operation.
7. Use Service Test Screens to energize chilled and condenser water
pumps. Verify flow input. Energize oil pump and verify pressure.
8. Start the unit and perform the following steps.
• Allow the unit to load to a current limit setting of 40% while air is purged
from the system.
• Once purging is complete, check overload calibration by slowly reducing
the current limit control.
• Compare the displayed current at the CLD with the measured
amperage.
Note: If the displayed current limit setting is not within 5% of the measured
amperage, call ABU service for troubleshooting instructions.
9. Use a thermometer to measure saturated evaporator refrigerant temperature. Compare to temperature being displayed at the CLD.
10.Operate the chiller through its normal operating range to determine if
the control adjustments are adequate.
11. Complete the post conversion checkout by completing the following
logs.
Once the starter and FastPak™ control panel checkout procedures are
completed successfully, the conversion process is complete.

Operation - Chiller Control System
Safety and operating controls are housed in the FastPak™ control panel,
the starter panel (optional) and the purge control panel (optional). The
FastPak control consists of a modular design partitioned by major function
or group of functions. All modules communicate with each other through
the IPC circuit. The modules and major components within each of these
control groups are described below. All wiring to the modules are to plug
gable terminal blocks. Unit mounted temperature sensors, pressure trans
ducers and functional switches provide analog and binary inputs to the
various modules.
a. Chiller Module
The Chiller module is the Master-of-the-Chiller, communicating commands
to other modules and collecting data/status/diagnostic information from
other modules over the IPC. The Chiller module performs the leaving
chilled water temperature and limit control algorithms arbitrating capacity
against any operating limit the chiller may find itself working against. The
chiller module contains nonvolatile memory for valid setpoints and retaining them on any power loss. Inputs and outputs are chilled water system
level I/O including evaporator and condenser water temperatures, evapora
tor and condenser water pump relays, programmable status and alarm relays, external auto-stop, emergency stop, oil differential pressure switch, oil
temperature, optional condenser refrigerant pressure transducer, vent line
valve operation, and oil tank heater and pump operation. Connection
points for the Chiller module (1U1) are shown in the wiring diagrams at the
end of this manual.
-
-
-
b. Scorpio Module
The Scorpio module drives the Inlet Guide Vane Actuator (stepper or pulse)
and serves as an input/output expander. These inputs and outputs include
motor winding temperatures, bearing temperatures, discharge temperature,
saturated evaporator refrigerant temperature, optional oil differential pres
sure transducer, safety string and IGV operation. Connection points for the
Scorpio module (1U3) are shown in the wiring diagrams at the end of this
manual.
c. Starter Module
The optional Starter module provides control of the starter when starting,
running and stopping the motor. The starter module provides protection to
both the motor and the compressor starter in the form of starting and running overload, phase reversal, phase loss, phase unbalance, momentary
power loss and compressor surge. Typical wiring connections to the
Starter module (2U1) are shown in the wiring diagrams at the end of this
manual.
d. Purge Module
The optional purge module is located in the purge control panel and pro
vides all the inputs and outputs to control the purge, optimizing both purge
and chiller efficiency. Connection points for the Purge module (3U1) are
shown in the wiring diagrams at the end of this manual.

Operation - Chiller Control System
e. Clear Language Display Module
The Clear Language Display (CLD) module, located on the FastPak™
door, provides display of chiller data and access to operator/service per
sonnel controls, setpoints and machine setup information. The front face
of the CLD consists of an LCD display, an LED and a keypad. The LCD
display presents the operating status of the unit, operating setpoints, oper
ating conditions, service test and diagnostics in a clear language display.
The LED is red and is illuminated when a manual reset is required to re
store the machine to full operation. The keypad has 16 keys arranged in a
4 x 4 matrix. The wiring connections to the CLD module (1U4) are shown
in the wiring diagrams at the end of this manual.
f. Remote Clear Language Display Panel and Remote Clear
Language Display Interface Module
As an option, the remote CLD permits the operator to remotely operate 1 4 chillers. The remote CLD works like the local CLD with two exceptions,
1) a local stop command takes precidence over all other remote or
external devices, and 2) the remote CLD’s custom report is independent of
the local CLD’s custom report. Each chiller required to communicate to a
remote CLD will require the Remote Clear Language Display Interface
Module (IPC Buffer, 1U9).
g. Tracer Communications Interface
-
-
-
TCI Comm3 is an optional module that provides a 1200 baud bi-directional
link to Tracer 100 panels. Tracer Comm4 is an optional module that provides a bi-directional communication link to Tracer Summit.
h. Printer Interface Module
The printer Interface module provides a pre-formatted chiller log to a
printer. The printer interface can be programmed via the CLD to print a
chiller log on command, at the time of a diagnostic, and/or on a periodic
basis. Each printed event is time and date stamped.

Operation - Chiller Control System
Sequence of Operation
This section will acquaint the operator with the control logic of the Fast
Pak™ control system. Be sure to refer to wiring diagrams at the end of this
manual when reviewing these step-by-step electrical sequences of opera
tion.
Note: Refer to the latest revision of CVHE-M-7 for a description of typical
mechanical operation. Refer to Sequence and Timing Functions on the fol
lowing page for start-run-shutdown sequence and timing functions.
With the unit in auto, the FastPak panel checks compressor motor winding
temperature, and a minimum 30 second delay is initiated if the winding
temperature is less than 165° F. If it is greater than 165° F, however, a 15
minute delay period begins. The chilled water pump relay is energized and
evaporator water flow is proven.
Next, the FastPak panel checks the leaving evaporator water temperature
and compares it to the chilled water setpoint. If the difference between
these values is less than the start differential setpoint, cooling is not
needed.
If the FastPak panel determines that the difference between the evaporator
leaving water temperature and chilled water setpoint exceeds the start differential setpoint, the unit enters the Initiate Start Mode and the oil pump
and the condenser water pump are started.
If condenser water flow is not proven (i.e. flow switch 5S2 does not close)
within 4.25 minutes, the unit is locked out on an MMR diagnostic.
-
-
-
Oil pressure must be verified within an adjustable time period or an MMR
diagnostic is generated.
When less than 5 seconds remain on the restart inhibit, the pre-start starter
test is conducted on Wye-Delta starters (if optional Starter module is in
stalled and contactors are controlled directly). If faults are detected, the
unit’s compressor will not start and a MMR diagnostic will be generated.
After the pre-start starter test, the FastPak panel sends a start signal to the
compressor starter. Within 2 seconds, current must be detected. If there is
no current, a diagnostic will be called out. Proof of transition must occur
within 2.5 seconds of transition initiation, or startup is aborted and the unit
goes into the post lube mode and a diagnostic is generated.
If the compressor motor starts successfully, “Unit is Running” appears on
the display. At this time the purge unit will start operating on automatic and
will continue running as long as the chiller compressor is running.
Whenever the FastPak panel detects an MMR diagnostic condition, unit
operation is locked out and manual reset is required before the startup se
quence can begin again. If the fault condition has not cleared, the FastPak
will not permit restart.

When the cooling requirement is satisfied, the FastPak™ panel originates
a shutdown signal. The inlet guide vanes are driven closed for 50 seconds,
and the unit enters an adjustable post lube period. The compressor motor
and condenser water pump starter are deenergized immediately, but the oil
pump continues to run during this post lube interval. The evaporator pump
will continue to run.
Once the post lube cycle is complete, the unit returns to the auto mode.

Remote Human Interface
General Characteristics
Each unit control can support two human interfaces, one machine
mounted (”local”) and one remote. A remote human interface is not
weatherproof, and is intended for indoor use. The remote human
interface is mounted in a plastic enclosure. It uses a molded rubber
keypad, not a membrane keypad. The keys will have the same labels on
both the local and remote keypad.
IPC Buffer
The use of a remote human interface requires that an additional module
be added to the unit control. The IPC Buffer Module is added, to buffer
and protect the inter processor communication bus. This is required
because the bus is brought outside the unit. The buffered IPC link will be
electrically identical to the COM4 non-isolated protected digital
communications link. With the correct twisted pair type, the remote
display can be 5000 feet from the unit.
Multiple Unit Communication
The machine mounted human interface communicates only with its
associated unit. The standard remote human interface communicates
with one unit. The remote human interface has an option that enables it
to communicate with up to four units. An extra circuit board is added to
provide the three additional communication channels. A separate wire
pair is run from each unit control to the remote human interface.
Configuration
The remote human interface uses the same circuit board and software as
the machine mounted human interface. Each circuit board must be
configured as either local or remote by the placement of a shorting block
on pins labeled 5 on the circuit board. When 5 pins 1 and 2 are
connected together, the human interface acts as the local human
interface. When 5 pins 1 and 2 are not connected together, the human
interface acts as a remote human interface.
The remote human interface will detect the presence of the multiple unit
option board by using the internal loop back nature of the RS485
transceiver chip. On power up, after the self test is complete, and after
the human interface identifies itself as remote, the human interface sends
a character on the unit four communication line and looks for a response.
Any response indicate the option board is present, since the character
may be overwriting a message on the line and result in a modified
character or a communication error indication.
Operation
The operation of the remote human interface will be identical to the
operation of the machine mounted human interface, with the following
exceptions.

If the new unit data is not received after 5 seconds, the following display

Troubleshooting and Diagnostics
Diagnostic information is provided here to allow the operator
to identify a number of system malfunctions, should any
occur. (If mechanical problems do occur, however, contact a
qualified service organization to ensure proper diagnosis and
repair of the unit.)
If the red light on the control panel is flashing, an MMR
diagnostic has occurred. The diagnostic must be analyzed,
corrections made by qualified personnel, and the MMR
diagnostic reset before the chiller can be returned to
operation.

The third screen will be the chiller operating mode display that was
present at the time that the most recent diagnostic occurred.
If there are one or more diagnostics present, the following displays will
be inserted into the display sequence. Diagnostics will be listed in
order of occurrence from newest to oldest. Diagnostics will be
displayed on two screens. The two screens will vary slightly depending
on whether the diagnostic is active or historic.
The first active diagnostic screen will be:
[Sequence Number ][Diagnostic Number ]
[Next][Diagnostic type]
The sequence number will run from 1 through n (n<=20) and number
the diagnostics sequentially where the most recent diagnostic is
sequence number [01].
The possible replacements for “diagnostic” messages are:
Warning Only - Reset Not Red (Applies to all IFW diagnostics)
Unit Shutdown - Reset Red (Applies to all MMR diagnostics)
Unit Shutdown - Automatic Reset (Applies to all MAR diagnostics)
The second active diagnostic display screen will contain the diagnostic
sequence number, a time and date stamp, and a help message
suggesting possible service procedures. The second active diagnostic
display screen will be:

Clearing Diagnostics
At the end of the diagnostic menu, there will be four screens which
allow the user to Clear/Reset the different diagnostic groups.
1. If any active diagnostics are present, the following screen will be
displayed:
Press (Enter) To Clr Active Diagnostics
And Shutdown/Reset System
If the enter key is depressed, the following message is displayed for
two seconds.
Active Diagnostics Have Been Cleared
System Is Resetting
The display will be reset to the operating mode screen of the chiller
report after this message clears.
2. If any historic diagnostics are present, the following screen will be
displayed:
Press (Enter) To
Clear Historic Diagnostics
If the enter key is depressed, the following message is displayed for
four seconds.
Historic Diagnostics Have Been Cleared
Diagnostic Report Is Being Reset
The display will be reset to the top of the Diagnostic Menu after this
message clears.
3. If any purge diagnostics are present, the following screen will be
displayed:
Press (Enter) To
Clear Purge Diagnostics
If the enter key is depressed, the following message is displayed for
four seconds.

4. If any IPC refrigerant monitor diagnostics are present, the following
screen will be displayed:
Press (+) To
Silence Rfgt Mon Audible Alarm
Note: Pressing (+) will silence the audible alarm. The IPC refrigerant
monitor will cause all the refrigerant monitor alarms (diagnostics) to
become non-latching for approximately 7.5 seconds. This allows any
latching alarms to clear if the trip condition has been removed. This
clearing function differs from the balance of FastPak in that the

New Diagnostic Display
When a new diagnostic is sensed by the system, the display will reset
to the diagnostic menu. A “one-time” screen will be displayed to inform
the user that a new diagnostic has been detected. This screen will vary
depending on the type of diagnostic detected. The two major
categories are those which are informational only, and those which
have resulted in machine shutdown.
If the diagnostic is an MMR/MAR, the screen will be:
***A MACHINE SHUTDOWN HAS OCCURRED***
Press (Next) for More
Otherwise, the screen will be:
A new warning has been detected
Press (Next) for More
This screen will be inserted into the diagnostic menu directly after the
“Diagnostic Report Follows: screen. Pressing (Next) will therefore take
the user to the ”Press (Next) to display operating mode at time of last
diagnostic" screen. If (Next) or (Prev) is pressed, this screen will no
longer be in the display sequence.

Diagnostic Codes
As shown below, a “LATCHING” diagnostic is a condition which
causes the machine or a portion of the machine as noted to shut down
and requires a manual reset to restore operation. A diagnostic that is
non-latching resets automatically when the condition causing the
diagnostic goes away. A non-latching diagnostic shuts down the
machine or a part of the machine if so indicated. If a diagnostic is
informative only, no machine or circuit action is taken except to load a
diagnostic code into the last diagnostic register.
Unless otherwise stated, all active diagnostics will be lost on loss of
power.
DIAGNOSTIC T PES AND ACTION:
MMR = MACHINE SHUTDOWN - MANUAL RESET
MAR = MACHINE SHUTDOWN - AUTO RESET
IFW= INFORMATION - WARNING May or may not affect machine
operation; lowest level of diagnostic.
Remotely Resettable Diagnostics:
Except for the following, all diagnostics can be reset remotely from
either the Remote Clear Language Display or the Tracer. The
following diagnostics shall only be resettable ONLY at the local Clear
Language Display, e.g., with the operator standing at the unit.
