General Information

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 modifica-
tions are complete, and that the chiller is functioning normally.
An important aspect of the chiller maintenance program is the regular com-
pletion of records. Attached are copies of the:
•“Water ooled hillers with FastPak ommissioning hecklist & startup
Test Log”
•“startup Test Log for Water ooled hillers with FastPak ontrol 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 alibrate 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:
•hoose Inlet Guide Vane Output Type <Stepper Motor> from the
Machine onfiguration menu and Vane ontrol <Manual> from the
Service Test menu. Verify that actuator operates from 0-100% (0-5"
stroke) open.
•onnect 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.
VR -M-1D 5
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:
•hoose Inlet Guide Vane Output Type <Pulsed> from the Machine
onfiguration menu.
•In the Service Test menu, choose Manual Loading/Unloading Duty ycle
<50%>.
•Next, choose IGV ontrol <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. heck 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.
•ompare the displayed current at the LD 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 tem-
perature. ompare to temperature being displayed at the LD.
10.Operate the chiller through its normal operating range to determine if
the control adjustments are adequate.
11. omplete 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.

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 IP 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 hiller module is the Master-of-the- hiller, communicating commands
to other modules and collecting data/status/diagnostic information from
other modules over the IP . The hiller 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 retain-
ing 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 re-
lays, 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. onnection
points for the hiller 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. onnection 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 run-
ning 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. onnection points for the Purge module (3U1) are
shown in the wiring diagrams at the end of this manual.
