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.

Post-Conversion Checkout
When the vanes are fully open, press <Next> until the screen showing
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.

Sequence and Timing Functions
Operation - TCI Setup Settings
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.

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.

to the screen as a visual aid. The last six keystrokes represent the current password, and up to twenty keystrokes can be entered.
An incorrect password, or the twenty-first keystroke will result in the password message “Invalid Password”.
If the password status is unlocked, the password message will be “Press (Enter) to Lock”. Whenever a password is in use the “Press

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.
