ISTORY OF COMPANY
Henry Vogt Machine Co. was founded as a small machine shop in Louisville, Kentucky in
1880. In 1938, Vogt built the first Tube-Ice® machine and revolutionized the ice-making
industry. Our first “sized-ice” machine quickly replaced the old can-ice plants, which required
much hard labor and large amounts of floor space for freezing, cutting, and crushing ice by
hand.
Today, Vogt Ice , LLC carries on the tradition as one of the world’s leading producers of icemaking equipment.
Preview
that we have learned in over a century of ice machine manufacturing.
Furnished with your machine is the “Certificate of Test”--the report of operating data that is a
record of the unit’s satisfactory operation on our factory test floor.
This manual is designed to assist you in the installation, start-up, and maintenance of your
unit. Your VT® machine will give you many years of service when you install it, maintain it,
and service it properly.
Please read your manual carefully before attempting installation, operation, or servicing of this
piece of equipment.
If you have additional questions, please call your distributor. Also, feel free to phone the
factory direct at (502) 635-3000 or 1-800-853-8648.

all local, state, and federal, etc. ordinances and laws regarding
the handling, storing, and use of R404A.
! CAUTION !
Inspection.

Important Safety Notice.
backgrounds of electrical, refrigeration and mechanical experience. Any attempt to repair major equipment
may result in personal injury and property damage. The manufacturer or seller cannot be responsible for
the interpretation of this information, nor can it assume any liability in connection with its use.
Special Precautions To Be Observed When Charging Refrigeration Systems.
technically-qualified persons, experienced and knowledgeable in the handling of refrigerant and operation
of refrigeration systems, should perform the operations described in this manual. All local, federal, and
EPA regulations must be strictly adhered to when handling refrigerants.
If a refrigeration system is being charged from refrigerant cylinders, disconnect each cylinder when empty
or when the system is fully charged. A gage should be installed in the charging line to indicate refrigerant
cylinder pressure. The cylinder may be considered empty of liquid R404A refrigerant when the gage
pressure is 25 pounds or less, and there is no frost on the cylinder. Close the refrigerant charging valve
and cylinder valve before disconnecting the cylinder. Loosen the union in the refrigerant charging line-carefully to avoid unnecessary and illegal release of refrigerant into the atmosphere.
Immediately close system charging valve at commencement of defrost or thawing
cycle if refrigerant cylinder is connected. Never leave a refrigerant cylinder
connected to system except during charging operation. Failure to observe either
of these precautions can result in transferring refrigerant from the system to the
refrigerant cylinder, over-filling it, and possibly causing the cylinder to rupture
because of pressure from expansion of the liquid refrigerant brought on by an
increase in temperature.
Always store cylinders containing refrigerant in a cool place. They should never be exposed to
temperatures higher than 110°F and should be stored in a manner to prevent abnormal mechanical shocks.
Also, transferring refrigerant from a refrigeration system into a cylinder can be very dangerous and is not
recommended.
It is not recommended that refrigerant be transferred from a refrigeration system
directly into a cylinder. If such a transfer is made, the refrigerant cylinder must be
an approved, CLEAN cylinder--free of any contaminants or foreign materials--and
must be connected to an approved recovery mechanism with a safety shutoff
sensor to assure contents do not exceed net weight specified by cylinder
manufacturer or any applicable code requirements.

Explanation.
PLC controls the sequence of events and monitors the ice machine functions. The operational sequences of
the VT-Series ice machine can be described best as a series of six different modes. Each mode identifies
and defines a sequence of events that occur while in that mode and thereby cause it to move to the next
mode. Only one mode is active at a time.
Start-Up Mode.
machine at the time of installation, after a power interruption, or after a machine fault. During Start-up, the
machine will not start for two hours. This gives the crankcase heater time to boil any refrigerant out of the
compressor. The start-up mode may be bypassed at any time by pressing the “Manual Harvest” (Start)
button to immediately advance to the standby mode.
NOTE: While the machine is in the Start-Up Mode, the Fault Indicator light will remain “on” (will not be
blinking).
The VT-Series ice machine is controlled by a PLC (Programmable Logic Controller). The

Preventive Maintenance
For The Manager Who Depends Upon This Machine
For Efficient Operation.
“Preventive Maintenance” simply means that you or a delegated employee makes a daily
visual check of your Vogt Ice machine. Here is what to look for and why:
Daily checklist:
1. Is the machine running or is the bin full
2. Bin doors kept closed
3. Thermostat sensor in bracket
4. Does all ice discharge during harvest
5. Cleanliness
6. Unusual noises
Why? When you make these simple observations on a daily basis, you insure the smooth
production of ice for your facility. When you are aware of the proper operating conditions
and observe them on a daily basis, changes in these conditions can alert you to changes
in the operation of the machine which may require maintenance--long before a service
situation arises.
Note To Manager or Owner
The following page is a complete Preventative Maintenance Schedule that should be
performed each 90 days. The Preventative Maintenance page may be copied and given
to your service person. It should be signed, dated, and returned to you for permanent
record.

the fin face of the condenser. A vacuum cleaner, compressed air, or a brush may be used to remove any
accumulation of loose dirt from the fin section of the condenser.
For the removal of more severe accumulations of dirt or foreign materials, a detergent-type cleaner can be
used. This cleaning agent can be supplied by your local refrigeration supply house. Follow the
manufacturer’s instructions when using a liquid cleaner.
If fins have been damaged, they should be straightened with the proper fin comb.
Compressor Oil.
should be watched carefully for the first hour to make certain the proper lubrication is being maintained. The
oil may become low in the crankcase on an initial start-up if the electrical current has been interrupted to the
machine, thus de-energizing the compressor crankcase heater.
Before starting the machine again, the heater should be energized for a time period of at least two hours to
evaporate refrigerant that may have condensed in the crankcase during the shutdown period. If the oil level
is low after start-up, it should begin to return after a short period of operation.
The oil level should be checked frequently, particularly during the start-up operation, to see that a sufficient
amount of oil remains in the crankcase. While it is important to observe the oil splash during operation, the
true level can be obtained only when the compressor is stopped. With the compressor idle, the oil level
should be between 1/2 to 3/4 of the sight glass, but not above the top of the sightglass.
In starting and charging the unit, the oil sight glass in the crankcase of the compressor
Visual inspection will indicate if dirt is accumulating and clogging
Although the machine was shipped with the oil charge, which was originally added for the test operation, it
may be necessary to add some oil when or if new refrigerant is added to the system.
An oil pump should be used to force any oil that may be required into the system. Oil may be added to the
compressor of all units through the compressor oil charging port. Air should be purged from the oil pump
discharge line by forcing some oil through the line before tightening the charging port.

REEZE-UP”
The following situations may cause machine “freeze-up”:
1. Harvest hold switch is improperly set
2. Improper fan control setting
3. Low head pressure limiting available gas for defrost
4. Dirty, scratched, or dented evaporator surface
5. Chopper motor or motor contactor defective
6. Interruption of electric service
7. Off on low pressure and reset without clearing tubes.
8. Low pressure safety switch improperly adjusted, causing termination prior to harvest.
9. Loss of water pressure.
10. Defective hot gas solenoid valve.
11. TXV not adjusted properly or functioning properly. Ice freezing too far up tube.
Note: If ice is freezing too high (onto the top flange holding the evaporator) the ice may not drop
from the evaoprator tubing. See page 8-8 for adjusting TXV.
Clearing a “freeze-up can be accomplished by placing “On/Off/Clean” selector switch in the “Clean”
position and circulating water over the tubes.
any foreign objects (example: hammer or screw driver) may damage tube
surface. If tube is dented or scratched, ice will not release properly. This
will void the evaporator warranty.

RINCIPLE OF OPERATION
The Vogt® VT Series line of ice making machines from Vogt® Tube Ice®, LLC, combines state-of-the-art
technology and efficiency with a reputation for quality and reliability developed over four decades of
manufacturing.
In the Vogt® VT Series icemaker, ice is produced on both walls of vertically suspended cylindrical tubes with
recirculating water. As ice is produced, makeup water is fed to the water tank via float valve. Freeze time
and harvest time are controlled by a Programmable Logic Controller (PLC).
In freeze cycle, the liquid feed valve is “open” (R404A machines only) and the compressor and water pump
are “on”. At the end of the Freeze cycle, the PLC initiates the Harvest cycle were the hot gas solenoid
valves and chopper motor are energized, and the water pump is turned “off” and liquid feed valve “closed”.
Bin control or remote on/off switch will allow machine to complete a freeze and harvest cycle prior to
interrupting operation. For R404A machines, the machine will go thru a Pumpdown before cycling off.

Oil Failure Switch: 12A2117A05 (Copeland Sentronic) On compressors manufactured before March 2011.
This device monitors the compressor oil pump differential pressure. If oil pressure drops below 7-9 psig for a
period of two minutes, the Sentronic module will open the control circuit contact and shut the machine off.
Factory set @ 7-9 psig (Manual reset)
CoreSense: Replaces Copeland Sentronic Oil Pressure Safety module on all Discus compressor and the
Electronic Motor Protector module in 4D & 6D compressors. Note: 2D & 3D compressor will still have
Internal Line Break overload protection.
The oil pressure monitoring portion of the CoreSense will act very similar to the Sentronic Oil Pressure
Safety switch. A current transformer (CT) in the compressor junction box determines when the compressor
is running and starts monitoring oil pressure.
The CoreSense module has power applied at all times to allow for more detailed fault notification. An LED
will flash when a fault occurs. The number of flashes will identify the fault condition.

Adjusting TXV:
flange. Freezing too high on the evaporator may cause ice to hang up on tubes and not release properly.
Freezing too high can also indicate that the superheat is too low and that liquid refrigerant may be coming
back to the compressor. This liquid refrigerant can damage or destroy the compressor.
Note:
tubes being fed by a particular TXV to have ice 2 or 3 inches higher than the other. This is normal
and will not affect capacity. DO NOT OPEN TXV in an attempt to get ice to form equally on both
freezer tubes. This can cause one of the tubes to be overfed and bring liquid refrigerant back to the
compressor. This can damage and/or shorten the life of the compressor.
On VT100’s, the ice may not freeze all the way up on all tubes. It is normal for one of the

Power Monitor
Wagner Model #: DTP-3
All Vogt Tube-Ice machine models are available from the factory with a three phase line voltage
power monitor with LCD display. The units are also available for after market or retrofit installation.
These units monitor line voltage inputs from 190 to 610 volts and provide protection against line
voltage variances which can damage or destroy the compressor motor. Features include automatic
system shutdown and restart based on current line conditions, a voltmeter, and a non-volatile
system memory so settings are retained even if power is lost. If machine is ordered with this option
the power monitor can be factory set to customer specifications. The Vogt Part number for a power
monitor retrofit kit is 12A7700K01.
The Display
The display normally shows the AB BC CA line voltages.
If the unit is waiting on a timer, that timer will be displayed. The timer display may be switched off by
pressing SELECT. The LCD will then display the normal AB BC CA line voltage pairs.
Pressing the SELECT button once shows the contactor load side voltages (if the load side option is
connected). The display automatically returns to the display of line side voltage after a few seconds.
Press the Select button to step through the parameters. As you step through the parameters, the
selected parameter will flash. Use the up and down arrow keys to adjust to the desired operating value.

Parameters adjustment (in order of display)
Active display of Line Voltage (this is the default normal display)
Active display of Load Side Voltage (if connected)
Voltage Set Point
(VAC Flashes) The value may be adjusted by pressing the up and down arrows. This may be set to the
normal operating voltage of the device being protected in one volt increments.
Under/over Voltage Tolerance in %
(UNDERVOLTAGE/OVERVOLTAGE flashes)
The value may be adjusted by pressing the up and down arrows.
Imbalance Voltage Tolerance in %
(% IMBALANCE flashes) The value may be adjusted by pressing the up and down arrows.
Lockout Time in seconds
(SECONDS flashes) The value may be adjusted by pressing the up and down arrows. (This is the delay on
break timer value)
Delay time in seconds and tenths of seconds
(RESP. SECONDS flashes) The value may be adjusted by pressing the up and down arrows. This is the time
that a fault is allowed before shutdown occurs.
Control mode
(ON OFF AUTO flashes) The value may be adjusted to OFF (load will not turn on), ON (load will turn on
whenever there are not faults and timers are finished) and AUTO (Load will turn on when there is a control
input).
Contactor fault monitor mode
(CONTACTOR FAULT flashes) This option allows you to monitor the contactor and lock it out if the line
voltage and load side varies by more than 5 volts. Pressing the up and down arrows selects off (default) or on.
The load side of the contactor must be connected to the load terminals of the DTP-3 to use this option.
Display of fault memories
(MEM flashes) Pressing up or down displays the last fault conditions that took the unit off line. The first 25
faults are recorded. The top number displayed represents the fault memory. The middle number
represents the total number of faults that have occurred since the fault memory was cleared.
To clear the memory, press and hold the up and down keys until the display is cleared.
Notes
If you press SELECT and do not change a parameter by pressing the up or down arrow keys, the
DTP-3 automatically returns to displaying the line voltage in a few seconds.
The new settings are saved in permanent memory when the display returns to displaying the line
voltage. The new settings may be verified by pressing the select button to sequence through the
various parameters.
To prevent tripping on a 1 volt change, the DTP-3 automatically calculates cut-in voltages for the
return from undervoltage conditions. The cut-out voltage is always based on user voltage and
tolerance settings, while the cut-in voltage is 3% closer to the nominal voltage setting. This quality
is sometimes referred to as hysterisis. This is to help reduce oscillation that may occur on weak
power distribution system. When the load is switched off due to undervoltage, the line voltage will
increase. Without the hystersis, the monitor would switch the load back on, the line voltage would
again drop, and cause a continuous on-off-on cycling.
