ISTORY
OF
C
OMPANY
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 ice-
making equipment.
Preview
Vogt

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.

VT Service Manual
General Information
Receipt Of Your Ice Machine
! CAUTION !
Only service personnel experienced in refrigeration and
qualified to work on high amperage electrical equipment should
be allowed to install or service this VT ice machine.
Eye protection should be worn by all personnel
working on or around the VT machine.
It is very important that you are familiar with and adhere to
all local, state, and federal, etc. ordinances and laws regarding
the handling, storing, and use of R404A.
! CAUTION !
Inspection.
As soon as you receive your machine, inspect it for any damage. If damage is suspected,
note it on the shipper’s papers (i.e., the trucker’s Bill of Lading). Immediately make a separate written
request for inspection by the freight line’s agent. Any repair work or alteration to the machine without the
permission of the Vogt Ice can void the machine’s warranty. You should also notify your Vogt distributor or
the factory.

2. Installation Information
Important Safety Notice.
This information is intended for use by individuals possessing adequate
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.
Only
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.
! CAUTION !
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.
! CAUTION !
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.
! CAUTION !
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.
! CAUTION !

Storing Ice.
When storing ice in a bin, make sure the bin control sensor is mounted in the bin properly.
The sensor should be mounted on the right side of the bin approximately 8” –12” from the top of the bin.

Ice Bin Capacity.
Crushed ice weighs approximately 35 pounds per cubic ft. (35 lb/ft
3
). As ice drops
into a bin, it will pile up and slope naturally at about a 45° angle. This natural slope should be taken into
account when locating the bin thermostat sensor (or other bin level control) and when calculating the normal
bin capacity. If the ice is spread out by hand in the bin for maximum storage capacity, make sure a hazard
is not created by allowing ice to back up into the chute and jamming the cutter. Always allow enough room
below the chute for at least one harvest.

Adding Refrigerant / System Charging:
To charge the system with cycling fans, observe sight
glass during the ice making cycle. When the fans cycle off, the sight glass should clear in 8 to 10 seconds.
If it takes longer than 10 seconds to clear the glass, the unit is undercharge. Add refrigerant to
system at compressor suction port or the ¼” access fitting on suction line. (See Figure 4-6)
If the glass clears in less than 8 seconds, the unit is overcharged. Remove refrigerant from system
following EPA standards.
Note: Do not charge to a full sightglass. Do not charge in a harvest cycle.
If packaged unit is totally out of refrigerant, add amount specified on machines nameplate.

5. Electrical Controls
CONTROLS
Explanation.
The VT-Series ice machine is controlled by a PLC (Programmable Logic Controller). The
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.
The start-up mode is a function which prevents the premature automatic starting of the
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).
! CAUTION !
If the power has been turned off to the machine, make sure the compressor
crankcase is warm and there is no liquid refrigerant in with the oil before
restarting the unit.
! CAUTION !
Standby Mode.
The standby mode is a decision making mode. It monitors the position of all the various
switches in the control circuit and at the proper time decides which mode to advance to next.
Note: R404A machines are pumped down while in the Standby mode. If the pressure comes back up after
3 minutes, (the low pressure switch “closes”), the machine will go to the Pumpdown Mode.
Freeze Mode (Freeze Cycle).
The freeze mode is active during the normal ice making cycle. During
this time, liquid feed valve is energized (R404A machines only) and the circulating water pump and
compressor are running. The freeze time is determined by the PLC analog timer (0-3.5 min) plus 5 minutes.
(Minimum freeze cycle time = 5 minutes, maximum freeze cycle time = 8.5 minutes)

Electrical Controls
Harvest Mode (Thaw Cycle).
The harvest mode is normally initiated at the termination of the freeze
mode. At this time, the circulating water pump stops and the liquid feed valve closes (R404A machines
only). After five seconds, the “D” (thaw gas) solenoid valves open and the chopper motor starts. On split
VT40’s & VT60’s, the hot gas loop valve energizes and on VT100’s, the suction stop valve energizes when
the chopper starts and thaw gas valves open. When the suction pressure reaches the set point on the
Harvest Hold (HH) pressure switch (PLC input #2 light will turn “off”), the harvest timer will begin to time.
The harvest timer is an internal timer in the PLC set for 45 seconds.
The harvest mode is terminated by the PLC thaw (harvest) timer at which time the machine will begin
another freeze cycle. The harvest mode can also be terminated manually by pushing in the “Manual Harvest
(Start)” button.
Increasing Harvest Time – To increase the harvest cycle time, raise the HH pressure switch cut-out setting.
(See Figure 5-2) This will increase the time it takes for the suction pressure to reach the set-point on the
switch, thereby increasing the harvest time.
FIGURE 5-2
Harvest Hold Pressure Switch
(located on top of lowside control panel)
Long Harvest Cycle Safety – The PLC monitors harvest cycle time. If the suction pressure does not reach
the HH pressure switch set-point within 3 minutes, the machine will shut down and go to the Fault Mode.
NOTE: If the “Selector Switch” switch is in the “Off” position or the bin control is satisfied the machine will
complete the Freeze, Harvest and Pumpdown cycle before shutting off (standby mode). Machines with R22
do not go through a pumpdown cycle before shutting off.
Pumpdown Mode
(R404A machines only)
.
All R404A machines have a liquid feed solenoid valve and
go through a Pumpdown cycle before shutting off. During the Pumpdown cycle the water pump and
compressor are “on” and the liquid feed solenoid valve is “closed”. The machine will run in the Pumpdown
mode until the Low pressure safety switch “opens”. After shutting off on low pressure, the machine will go to
the Standby mode.
Note: If the suction pressure does not reach the cut-out point on the low pressure switch within 2 minutes,
the machine will fault out on a “Pumpdown Fault”.
Continuous Pumpdown
(R404A machines only). While in the Standby mode, the machine will
remain pumped down. After a 3 minute delay, if the pressure comes up in the freezer and the low pressure
safety switch “closes” (pressure gets above 20 psig), the compressor will come “on” and pump the machine
down.

Clean Mode.
The “Clean” mode is considered to be a maintenance or service function of the machine.
During this mode only the water pump will run.
The water pump can be stopped by simply moving the “Selector Switch” from the “Clean” to the “Off”
position. To restart the water pump, move the “Selector Switch” back to the “Clean” position and press the
“Manual Harvest (Start)” button. Ice machine cleaning solution can be circulated though the tubes to
accomplish the cleaning procedure. If the water pump is left to run in the clean mode for more than two
hours, the PLC will shut the machine off. The clean mode can be resumed by pushing the “Manual Harvest”
button.
NOTE: Running in Clean mode for extended period of time can cause excessive pressure to build up in the
freezer.
At the termination of the clean mode, the machine can be returned to ice making mode by putting the
“Selector Switch” in the “Ice” position and pressing the “Manual Harvest” button.
Fault Mode.
The VT Series is equipped with a PLC (programmable logic controller) that controls all
aspects of the operation. One of the functions of the PLC is to shut down the machine when a problem
arises and send a signal to the fault indicator light located on the front of the electrical panel. (Figure 5-3)
The red light will blink 1 to 6 times when a problem has caused the machine to shut down.

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.

Maintenance
Air-Cooled Condenser Cleaning.
Visual inspection will indicate if dirt is accumulating and clogging
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.
In starting and charging the unit, the oil sight glass in the crankcase of the compressor
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.
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.

The VT Series ice machine is equipped with a PLC (programmable logic controller) that controls all aspects
of the machines operation. One function of the PLC is to shut down the machine when a machine fault
occurs. By continuously monitoring the High and Low pressure safety switches, the harvest cycle time, and
the oil pressure, the PLC can determine if a problem exists.
Machine Fault Light -
if the machine shuts off due to a high pressure fault, low pressure fault, a "long
harvest cycle" fault or an oil pressure fault, the machine will not automatically restart. When a "fault" occurs,
the PLC sends a signal to the fault indicator light located on the control panel door.

:
Check main electrical fused disconnect or circuit breaker. If power has been off,
crankcase heater should be energized two (2) hours prior to starting.
Note: If no power to the lowside unit, check 10A breaker in condensing unit electrical enclosure.
High Pressure Safety:
Reset high pressure control switch. If tripped, install gauges observe operating
pressures to determine that compressor discharge pressure is within operating limits. If fans do not come
“on”, check circuit breaker in condensing unit control panel. For water cooled units, verify water supply and
water regulating valve setting.
Low Pressure Safety:
This switch will automatically reset when pressure comes up to the “cut-in” set
point. If tripped, install gauges observe operating pressures to determine that compressor suction pressure is
within operating limits. If suction pressure is low, check machine refrigerant charge.
Note: When the machine starts after a power failure or after the machine has cycled off on bin control or the
“on/off/clean” selector switch, the PLC do not look at the low pressure switch for 90 seconds.
Compressor Motor Overload Protector
(Sentronic before March 2011, CoreSense after March
2011)
:
Machines are equipped with a compressor protection device that opens in the event compressor
temperature or amperage reaches an extreme that could damage compressor. The device automatically
resets after compressor has cooled. CoreSense must be reset.
(Note: On VT80 & V100 Only). Note: This sensor is in series with the oil pressure safety switch. Fault #3 can
be either compressor motor overload or oil pressure.
CAUTION: If machine is off on motor overload protector, control cycle timer and
other components will continue to function although the compressor is off. The
machine or any of its components can start without warning causing serious injury.
Bin Control Open:
Adjust thermostat bin control as required. See page 8-3 for bin control error code.
Faulty Remote Off/On Switch:
Replace if necessary.
Compressor Contactor Defective:
Check wiring to line contactor to determine that "L" terminals
are supplied with power. Check contactor coil for open winding.
Oil Failure Switch
(Sentronic before March 2011, CoreSense after March 2011): Reset Sentronic oil
pressure safety switch. Check compressor oil level. If oil level in sightglass, check oil pressure.
Note: Verify proper operation of crankcase heater. Cold starts can cause oil loss.
Chopper Failure:
If the chopper motor fails to come on, the current sensing relay in the chopper motor
circuit will detect the absence of motor current and shut the machine off. See Machine “Freeze-Up”.

M
ACHINE
“F
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.
CAUTION: Clearing “freeze
-
ups” should be done using only water. Use of
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.

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.

PLC (Programmable Logic Controller).
The VT-Series ice machine is controlled by a PLC
(Programmable Logic Controller). The 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.

Adjusting TXV:
Ice should start forming on the evaporator tubes approximately four inches from the top
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:
On VT100’s, the ice may not freeze all the way up on all tubes. It is normal for one of the
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.
Ice Levels on Freezer Tubes (VT100)
Note: Ice level will
likely not be the same.
Note: Tube on the left should
not have ice closer than 4”
from freezer flange.

To lower ice level, the TXV can be closed by running the stem in. Do this by turning the TXV stem clockwise
as shown below. (looking up at the valve stem)
Note: Close TXV ¼ turn at a time. Observe several cycles before making further changes.
If ice is not freezing high enough on the evaporator tubes, the TXV can be opened by backing the stem out.
Do this by turning the TXV stem counter-clockwise. (looking up at the valve stem)
Note: Check expansion valve inlet strainer before opening valve. Clean strainer if necessary.
Open TXV ¼ turn at a time. Observe several cycles before making further changes.

Inlet Pressure Regulator:
This regulator valve is used on the split VT40, split VT60 and VT100. The
purpose of this valve is to maintain head pressure during the harvest cycle. (Set point = 160-170 psig)
Valve will be closed when inlet pressure is below the set point. This will allow all the discharge gas to go to
the evaporators during the harvest cycle. When pressure rises above the set point, valve will open and allow
discharge gas to pass through to the condenser.

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.
