1. General Information

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 making equipment.

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.

This information is intended for use by individuals possessing adequate

Only

! 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.

CONTROLS

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).

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

Freeze Mode (Freeze Cycle).

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)

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 VT80 & VT100 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

(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.

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.

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.

PRINCIPLE 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.

Pressure Switches

High Pressure Safety: 12A2117H01 (Penn)

This switch terminates operation of machine when high compressor discharge pressure occurs. Settings

Low Pressure Safety: 12A2117B08

This switch terminates operation of machine when low suction pressure occurs. 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. Settings

Fan Control Switch:

This switch cycles the condenser fan motors to maintain proper discharge pressure. Settings

Harvest Hold Switch: 12A2117B03 (Penn)

This switch stops harvest timer (holds machine in harvest) until the suction pressure comes up to the switch sets set point. Note: In low ambient conditions, the harvest time may be increased by raising the switch Cutout setting to 70-75 psig. Settings

Service Operations

Oil Failure Switch:

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.

Bin Control (Ranco Electronic Temperature Control)

With the Ranco electronic temperature control the ice must come in contact with the sensor to shut the machine off. The sensor should be installed in the bin using the standard bin thermostat mounting bracket. Three quarters of the sensor (black part) should hang below the bottom of the bracket.

Programming the Sensor

1) Press the “SET” button to enter the sensors setup mode

2) Select between “C”- Celsius and “F” - Fahrenheit

Use the up ▲or down ▼ key to select “F”

3) Press the “SET” button to set the Set point (S1 will be blinking) Use the up ▲ or down ▼ key to set the temperature at 38

4) Press the “SET” button to set the Differential (DIF 1 will be blinking) Use the up ▲ or down ▼ key to set the differential at 2

5) Select between “C1”- Cooling mode and “H1” - Heating mode Use the up ▲ or down ▼ key to select “C1”

Machine will shut off when temperature drops to 38

Note: The sensor will automatically exit the programming mode if no keys are depressed for a period of thirty seconds. Any settings that have been input to the control will be accepted at that point.

PLC (Programmable Logic Controller).

(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.

The VT-Series ice machine is controlled by a PLC

Adjusting TXV:

flange. Freezing too high on the evaporator may cause ice to hang up on tubes and not release properly. 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.

Ice should start forming on the evaporator tubes approximately two inches from the top

Close TXV – clockwise (freeze lower on tubes)

Remove TXV cap

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.

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.
