Safety

______________________________

We at Taylor Company, are committed to manufacturing safe operating and serviceable equipment. The many built-in safety features that are part of all Taylor equipment are aimed at protecting operators and trained service technicians alike.

This manual is intended exclusively for Taylor Company authorized service personnel.

Stationary appliances which are not equipped with a power cord and a plug or other device to disconnect the appliance from the power source must have an all-pole disconnecting device with a contact gap of at least 3 mm installed in the external installation.

Thismachinemustbeplacedonalevel surface. Failure to comply may result in personal injury or equipment damage.

DO NOT installthemachineinanarea where a water jet could be used to clean or rinse the freezer. Failure to follow this instruction may result in serious electrical shock.

DO NOT remove the door, beater, scraper blades, drive shaft or air/mix pump unless all control switches are in the OFF position. Failure to follow this instruction may result in severe personal injury from hazardous moving parts.

Refrigerant

______________________________

Taylor Company uses R404A refrigerant. This refrigerant is generally considered non-toxic and non-flammable; however, any gas under pressure is potentially hazardous.

NEVER fill any refrigerant cylinder completely with liquid. Filling the cylinder to approximately 80% will allow for normal expansion.

Refrigerant liquid sprayed onto the skin may cause serious damage to tissue. Keep eyes and skin protected. If refrigerant burns should occur, flush immediately with cold water. If burns are severe, apply ice packs and contact a physician immediately.

The Taylor Company reminds technicians to be cautious of government laws regarding refrigerant recovery, recycling, and reclaiming systems. If you have any questions regarding these laws, please contact the factory Service Department.

WARNING: R404A refrigerant used in conjunction

with polyolester oils is extremely moisture absorbent. When opening a refrigeration system, the maximum time the system is open must not exceed 15 minutes. Cap all open tubing to prevent humid air or water from being absorbed by the oil.

This machine is designed to operate indoors, under normal ambient temperatures of 70°-75°F (21°-24°C). The machine has successfully performed in high ambient temperatures of 104°F (40°C) at reduced capacities.

NOISE LEVEL: Airborne noise emission does not exceed 78 dB(A) when measured at a distance of

1.0 meter from the surface of the machine and at a height of 1.6 meters from the floor.

Introduction

Model C602

Compressor Warranty Disclaimer ______________________________

The refrigeration compressor(s) on this machine are warranted for the term indicated on the warranty card accompanying this machine. However, due to the Montreal Protocol and the U.S. Clean Air Act Amendments of 1990, many new refrigerants are being tested and developed; thus seeking their way into the service industry. Some of these new refrigerants are being advertised as drop-in replacements for numerous applications. It should be noted that, in the event of ordinary service to this machine’s refrigeration system, only the refrigerant specified on the affixed data label should be used. The unauthorized use of alternate refrigerants will void your compressor warranty. It will be the owners’ responsibility to make this fact known to any technicians they employ.

It should be noted, that Taylor does not warrant the refrigerant used in its equipment. For example, if the refrigerant is lost during the course of ordinary service to this machine, Taylor has no obligation to either supply or provide its replacement either at billable or unbillable terms. Taylor does have the obligation to recommend a suitable replacement if the original refrigerant is banned, obsoleted, or no longer available during the five year warranty of the compressor.

The Taylor Company will continue to monitor the industry and test new alternates as they are being developed. Should a new alternate prove, through our testing, that it would be accepted as a drop-in replacement, then the above disclaimer would become null and void. To find out the current status of an alternate refrigerant as it relates to your compressor, call the local Taylor Distributor or the Taylor Factory. Be prepared to provide the model/serial number of the unit in question.

Heat Cycle Failure Messages

To comply with health codes, heat treatment system freezers must complete a heat treatment cycle daily, and must be disassembled and brush cleaned a minimum of every 14 days. Brush cleaning is the normal disassembly and cleaning procedure found in the Operator Manual. Failure to follow these guidelines will cause the control to lock the freezer out of the AUTO mode.

Always comply with local guidelines for the maximum number of days allowed between brush clean cycles. (See the Manager/Service Menu for setting the Brush Clean interval, on page 21.)

If the Heat Treatment Cycle fails, the VFD will display a failure message and return the freezer to the STANDBY mode. A “lock” is defined as a special STANDBY mode of operation which does not allow the machine to operate in the AUTO mode.

There are two types of freezer lock conditions that can occur: Hard Lock or Soft Lock. A Hard Lock requires the machine be disassembled and brush cleaned. A Soft Lock can be corrected by either disassembling and brush cleaning the machine, or by starting another heat treatment cycle.

Selecting the WASH symbol following screen. (See Figure 12.)

To restore the message that identified the reason for the hard lock, turn the power switch OFF for five seconds and then return the power switch to the ON position. The original message with the reason for the Hard Lock will be displayed. The FAULT DESCRIPTION can also be found in the Manager or Service Menu (See page 22.)

The FREEZER LOCKED message will remain on the display until the brush clean requirements are fulfilled. The freezer must be disassembled in order to activate the five minute timer on the display screen. Once the timer counts down to zero, the lockout is cleared.

Reasons For Soft Lock

Following are the variable messages for soft lock failures that appear on the second line of the screen.

Power Switch Off

This soft lock will occur if the power switch is in the OFF position and greater than 24 hours have passed since the start of the 14 day timer, or the start of the last successful Heat Treatment Cycle.

Soft Lock: If a heat treatment cycle has not been initiated within the last 24 hours, a soft lock failure will occur. A soft lock allows the operator to correct the cause of the soft lock. The operator has the option of either starting another heat cycle or brush cleaning the machine. When a soft lock occurs, the machine will go into the STANDBY mode. The following message is displayed on the screen. The reason for the soft lock is indicated on the second line. (See Figure 16.)

SYRUP MOTOR SETUP

The Syrup Motor Setup option allows the service technician to adjust the running speed for each syrup pump motor in the calibration mode and the reverse time for the pump motor.

The proper syrup motor setting should be set to gradually fill the calibration cup. If the syrup motor setting is too fast the syrup will fill the cup too fast to accurately stop the flow at the proper level.

The recommended setting for the syrup motor is 85 for thin viscosity shake syrup. For thick viscosity syrup, the syrup motor setting may need to be set higher (100 - 160) if the flow rate is too slow or the amount of syrup measured in the Verification Mode is not within the specified range.

Figure 79

Each peristaltic pump motor must reverse the syrup flow momentarily when the flow is stopped in order to eliminate the pressure in the line and close the duckbill syrup valve. The reverse time setting for most thin viscosity syrups is 0.25 seconds. Thick viscosity syrup may require a slightly longer reverse time setting (0.26 – 0.32).

If the reverse time setting is too short, pressure remaining in the line may cause syrup to seep past the duckbill valve after the shake is dispensed. When this occurs, the flavoring will carry-over to the next serving.

If the reverse time setting is too long an air pocket may form in the syrup line connected to the freezer door. An air pocket in the line will delay syrup blending with the frozen mix causing unflavored product to be dispensed in the bottom of the cup.

Heat Treatment Cycle

The function of the Heat Treatment Cycle is to raise the temperature of the mix in the freezing cylinder(s) and hopper(s) high enough and quickly enough to destroy bacteria. When this has been accomplished, the temperatures must then be returned to a temperature low enough and quickly enough to retard spoilage.

The Heat Treatment Cycle must be successfully completed at least once every 24 hours or the freezer will automatically lock itself in the STANDBY mode.

Single freezing cylinder operation is now available. The software keeps track of the freezing cylinder(s) “in use”. Therefore, the Heat Treatment Cycle can now be performed on only one side, if the other side has not been placed in AUTO or STANDBY since the unit was last brush cleaned.

The Heat Treatment Cycle may be started automatically according to the AUTO HEAT CYCLE TIME.

IMPORTANT: The freezer must be operating in either the STANDBY or AUTO mode before a Heat Treatment Cycle can be started.

There are three phases in a Heat Treatment Cycle: Heat, Hold and Cool.

The Hold Phase

During the HOLD phase, the temperature of the product is “held” over 151.5_F(66_C) for a minimum of 30 minutes to ensure the destruction of all harmful bacteria in the product.

The Hold Phase Timer “times out” 30 minutes as long as all freezing cylinder and hopper temperatures remain above 151.5_F(66_ C) for the duration of the HOLD phase.

The Heat Soak Timer prevents the HOLD phase from entering the next COOL phase of the cycle until the 30 minutes is satisfied and until the total time of the HEAT and HOLD cycles combined is greater than 115 minutes.

The Cool Phase

During the COOL phase, the product in the freezing cylinder and the hopper are lowered to 41_F(5_C) or less. The unit must complete this phase in less than 120 minutes.

The COOL Phase Timer measures the maximum allowable time the unit can remain in the COOL phase. If the timer exceeds 120 minutes, the unit will lock-out.

The Heat Phase

During this phase, the temperatures of the product in the freezing cylinder and hopper are raised over

151.5_F(66_C) in 90 minutes or less.

The Heat Phase Timer “times out” the maximum allowable amount of time the unit can remain in the HEAT phase of the Heat Treatment Cycle. If the timer exceeds 90 minutes, the unit will lock-out.

Model C602

The Heat Cycle TT (Total Time) Timer “times out” the maximum allowable time the unit can remain in the Heat Treatment Cycle (4 hours). If the timer exceeds four hours, the unit will lock-out. This timer is a combination of the HEAT, HOLD, and COOL Phase Times.

When the entire Heat Treatment Cycle has been completed, the normal display will appear, indicating that the machine is operating in the STANDBY mode.

Systems, Controls and Operations

Heat Treatment Graph

During the HEAT and HOLD phases, the glycol is heated by the use of a glycol heater. During the COOL phase, the glycol and freezing cylinder product are refrigerated by the use of the machine’s main refrigeration system.

At the start of the HEAT phase the glycol heater begins to overcome the cold freezing cylinder temperature and the glycol temperature raises slowly to 178_F(81_C).

The purpose of the HEAT phase is to raise the product temperature above 150_F(65_C) within 90 minutes. To satisfy the control system, the product must actually reach 151.5_F(66_C). This requirement ensures that the 150_F(65_C) requirement has been met. Health laws require these parameters to be 150_F(65_C) in 90 minutes; however, the actual amount of time the freezer takes to accomplish this requirement is closer to 60 minutes.

Once the HEAT Phase is complete, it is necessary to complete the Heat Soak Timer. From the time the Heat Phase is started, 115 minutes must transpire before the cool phase may enter. Due to the implementation of the Heat Soak Timer, the Heat Cycle Data Screen will now refer to the HOLD phase as the “OVER” phase.

While in the COOL phase, the beater motor and the main refrigeration system operate continuously until the machine first cycles off. For the remainder of the COOL phase, the beater motor and compressor operate from a timed cycle. The timed cycle allows the beater motor to stop for two minutes and then run for six seconds. During the six seconds that the beater motor is on, if the viscosity is below setpoint, the compressor is turned on. When viscosity is satisfied, the compressor and the beater are turned off. The timed cycle continues in this manner until the COOL phase is complete.

Timers

Two Minute Stir Cycle

If either side of the machine is in the STANDBY mode, the beater motor for that side will turn on for six seconds every two minutes.

If any hopper is above the cut-in temperature, the beater stir cycle timer is activated.

Soft Serve - If the machine is in the HEAT mode, this two minute stir cycle will continue until the freezing cylinder temperature rises above 135_F (57_C). If the machine is in the AUTO mode or the COOL phase of the Heat Treatment Cycle, and the hopper is calling for refrigeration, the beater motor and compressor will continue to run until the viscosity setpoint has been reached.

Shake - If the machine is in the AUTO mode and the hopper is calling for refrigeration, the beater motor will run once every two minutes. If the freezing cylinder product viscosity has been satisfied during this beater run time, the beater motor will turn off. Otherwise, the compressor will also turn on and run until the freezing cylinder product viscosity has been satisfied. During the Heat Treatment Cycle the beater motor runs continuously until viscosity is satisfied in the Cool Phase after which the beater motor will run as in the AUTO mode to cool the hopper.

Mix Pump Timer

Shake - The mix pump will run for 10 seconds

anytime the unit is placed in the AUTO mode, but not from STANDBY.

Soft Serve - The mix pump will run for 30 seconds anytime the unit is placed in the AUTO mode.

Mix Draw Timer (Soft Serve Applicatio n Only)

During the AUTO mode, the mix pump will run for 5 30 seconds every time product is drawn from the machine. The factory setting is 10 seconds.

Draw Safety Timer (Shake Application Only)

During the AUTO mode, if the pyroelectric sensor has not detected the product level, the safety timer will terminate the draw. The draw safety timer is adjustable from 3 - 60 seconds. The recommended setting is five seconds longer than the time required to dispense the largest serving size (International = 11 seconds, Triple Thick Shake = 24 seconds).

Brush Clean Countdown

The Brush Clean Countdown displays on the control panel. It counts the number of days before the next brush cleaning is required. When the display has counted down to “1”, the following message will appear on the VFD screen. (See Figure 81.) The machine must be disassembled and brush cleaned within 24 hours.

Glycol Pump Timer

If either side of the machine is operating in the AUTO mode, and the hopper requires refrigeration, the glycol pump will operate one minute, discontinue for two minutes, then operate again for one minute. This pattern continues until hopper refrigeration is no longer required.

Heat Phase Timer

The Heat Phase Timer times out the maximum allowable time the unit can be in the Heat Phase of the Heat Treatment Cycle (90 minutes). If the timer exceeds 90 minutes, the unit will lock-out.

Hold Phase Timer

This timer assures that product in the freezing cylinder and the hopper are held above 150_F (65_C) for a minimum of 30 continuous minutes.

Heat Soak Timer

The Heat Soak Timer prevents the HOLD phase from entering the COOL phase until the HOLD phase requirements are met and the total time of the HEAT and HOLD phases is greater than 115 minutes.

The Cool Phase Timer times out the maximum allowable time the unit can remain in the COOL phase of the Heat Treatment Cycle (120 minutes). If the timer exceeds 120 minutes, the unit will lock out.

Safety Timeout

Once power is applied to the unit, a 60 second timer places the unit in an “IDLE” state. The tone is turned on in 0.5 second intervals, and a “Safety Timeout” message appears on the LCD. This timer can be aborted by pressing any key.

Brush Clean Timer

This timer times out 5 minutes when all conditions for a successful brush cleaning are met.

Glycol System

The following information describes the glycol system. For further understanding, see the Glycol Path diagram at the end of this chapter.

The glycol system serves two purposes. During the STANDBY and AUTO modes, the glycol is used to cool the mix hoppers. During the HEAT mode, the glycol is used to heat the mix in the hopper(s) and freezing cylinder(s).

Glycol is a heat transfer medium made up of 50% ethylene glycol and 50% distilled water.

Note: It is factory recommended to drain, flush and re-supply a fresh glycol mixture on a two-year maintenance schedule.

Standby and Auto

During a refrigeration mode, the freezing cylinders are cooled using refrigerant, and the product is controlled by viscosity during the AUTO mode and by temperature during the STANDBY mode.

The Heat Treatment Cycle

During the heating phase the heater is activated. For shake application, beater agitation will continue until the compressor cycles off. For soft serve application, the beater will agitate for six seconds every two minutes until the freezing cylinder product rises above 135_F(57_C).

During the HEAT phase, all refrigeration is cancelled, and the glycol will heat the freezing cylinder(s) and the hopper(s) to the set temperatures.

WARNING: Ethylene glycol is very harmful to your health. Swallowing glycol is fatal. Refer to M.S.D.S. Guidelines.

Note: If the glycol is purchased from the factory, it

is pre-mixed and ready to use. Otherwise, glycol should be mixed with distilled water in a ratio of 50% glycol and 50% distilled water.

Installing the Glycol Mixtu re

The hoppers are cooled in the following manner:

When a hopper temperature reaches the cut-in point, the glycol pump, solenoid valve, and beater stir cycle are all activated.

The glycol lines go (in order) through the heater, through the solenoid valve, around the freezing cylinder, and then to the hopper. In other words, the glycol is cooled directly by the freezing cylinder walls and is then pumped to the hoppers to cool the mix. Each hopper has one thermistor probe and can function independently.

Note: The heater is OFF during refrigeration modes.

In each hopper, there is an agitator paddle which is used to distribute the heat or cold evenly throughout the mix so the mix does not freeze or burn on the sides of the hopper. It runs continuously when the freezer is in the AUTO, STANDBY or HEAT mode. The agitator is driven by a motor and belt(s).

Step 1

Attach a hose (capable of depressing the shraeder valve) to the 1/4” flare fitting located beneath the accumulator tank. Remove the cap from the accumulator and place the opposite end of the hose into the accumulator tank.

Step 2

Using a pair of pliers, squeeze the tube located between the access fitting and the tube that leads to the bottom of the glycol accumulator tank.

Step 3

Fill the accumulator tank 2/3 full.

Step 4

Remove the necessary panels to expose the shake interface board. Locate the test pins marked, “W2, W3, W4, and W5”. Place a two pin jumper on the test pins marked “W4”. The jumper will activate the glycol pump and open the glycol solenoids (if applicable). The glycol existing in the accumulator will be pumped through the glycol system.

Model C602

Systems, Controls and Operations

Step 5

Monitor the level of glycol mixture in the tank and to be sure all air pockets are removed, continue to add more as necessary to maintain a 2/3 full level. Allow the unit to operate for a short period of time. Once the service hose starts to empty glycol back into the accumulator tank, the system is properly filled. Remove the jumper from the pins marked, “W4”. Release the pliers.

Step 6

Remove the service hose and replace the cap on the 1/4” flare fitting. Replace the accumulator tank cap.

Step 7

Check for glycol mixture leaks.

Replenishing the Glycol Mixture

Note: If the accumulator tank is empty, follow the

steps outlined in “Installing the Glycol Mixture”. If the unit needs replenishing, complete the following steps:

Step 1

Remove the cap from the glycol accumulator tank.

Step 2

Replenish the glycol mixture until the tank is 2/3 full.

Draining the Glycol Mixture

Step 1

Attach a service hose (capable of depressing the shraeder valve) to the 1/4” access fitting. Allow the opposite end of the hose to rest in an empty bucket.

Step 2

Using a pair of pliers, squeeze the tube located between the access fitting and the tube leading to the bottom of the glycol accumulator tank.

Step 3

Remove the cap from the top of the accumulator tank. The glycol will begin to flow into the bucket.

Step 4

Remove the necessary panels to expose the shake interface board. Locate the test pins marked, “W2, W3, W4, and W5”. Place a two pin jumper on the test pins marked, “W4”.

Step 5

Once the glycol mixture stops flowing into the bucket, replace the cap on the glycol accumulator tank.

Step 6

Disconnect the outlet line from the glycol pump. Blow air or nitrogen through the outlet line from the glycol pump. This procedure will fully drain the system.

Step 3

Replace the cap on the accumulator.

Step 4

Check for glycol mixture leaks.

Step 7

Once the system is fully drained, remove the service hose and replace the access cap. Replace the outlet line of the glycol pump to proper position. Remove the pliers.

Setting Viscosity

Viscosity

Viscosity is the term used when referring to product appearance, temperature, thickness and firmness.

Note: See page 27 to adjust viscosity settings.

Shake

The shake viscosity is measured by monitoring the gap opening of the beater drive coupling which is mounted on the output shaft of the gear unit. The gear unit turns the spring loaded drive coupling. As the product in the freezing cylinder becomes thicker, the springs collapse, and the size of the gaps change.

As the gaps narrow, the Hedlunds (HD’s) increase. As the product thickens (becomes colder) the HD’s increase. After achieving a pre-adjusted HD setting, the refrigeration cycle discontinues.

For standard units, the serving temperature of a flavored shake may range from 24_Fto26_F (-4.4_Cto-3.3_C).

For Triple Thick Shake units, the serving temperature may range from 22_Fto24_F(-5.6_C to -4.4_C)

Soft Serve

The soft serve viscosity is measured by monitoring the amperage load of the beater motor. The amperage load of the beater motor is low when the product in the freezing cylinder is liquid. As the product freezes (thickens), the amperage load increases. When the amperage load reaches the setpoint, the refrigeration cycle discontinues.

The factory default setting (setpoint) for soft serve viscosity is 2.8 A. The amperage measurement is determined by monitoring the L1 leg of power being delivered to the beater motor. To adjust the serving viscosity, it may be necessary to raise or lower the amperage setpoint. Adjust in increases of 0.1 amp.

The serving temperature of soft serve product may vary throughout the day. The serving temperature may range from 16_Fto19_F(-8.8_Cto-7.2_C).

Figure 84

The factory default setting for cycle off viscosity is 4000 HD’s. To adjust the serving viscosity, it may be necessary to raise or lower the HD setting. Adjust in increases of 100 HD’s at a time. Note: Be sure that the syrups are correctly calibrated before determining the proper serving viscosity.

Systems, Controls and Operations

Model C602

Portion Control (Shake)

The portion control sensor, located in the cup bracket, is a pyro-electric sensor which responds to temperature changes of any kind. When the draw valve is opened (during the AUTO mode) and the product level in the cup reaches the sensor, it will recognize a temperature change. The control board then automatically closes the draw valve.

Portion Control Operation

The interface board receives 16 VAC from the transformer and converts it to 12 VDC for the personality board.

Auto Mode

If the sensor does not detect the product filling the cup, the control board will automatically close the draw valve after the Draw Safety Time has elapsed. (See Draw Safety Time, page 30.)

Heat Mode

During the heat mode, the flavor keys will not open the draw valve.

Portion Control Troubleshooting

At Personality Board:

Step 1

Verify that the shake personality board is properly connected to the interface board.

Step 2

Verify J3 (RED header) connections:

Pin 3 = WHITE: This is the cup-full signal that goes to the UVC through the interface board. It is normally less than .2 VDC when a cup-full is not sensed, and makes a momentary 5 VDC pulse when a cup-full is sensed.

Pin 2 = BLACK: This is the DC GROUND connection.

Pin 4 = RED: This is the +12 VDC power supply from the interface board.

At Pyro Sensor Board:

Step 1

Verify that the shake personality board is properly connected to the J3 (RED header):

Pin 1 - WHITE: This is the “sense” output of the sensor.

Pin 2 - BLACK: This is the DC GROUND connection.

Pin 3 = GREEN: This is the 2.5 VDC reference output of the sensor.

Pin 4 = RED: This is the +12 VDC power supply for the sensor.

Step 2

Verify that the wiring harness is properly connected on J2:

Pin 1 = 12 VDC

Pin 2 = This is the cup-full signal. It is normally less

than .2 VDC when a cup-full is not sensed, and makes a momentary 5 VDC pulse when a cup-full is sensed.

Pin 5 = GROUND

Universal Control (UVC3)

JP3

The Universal control is the command center for the machine. The software program, including multiple language selections, resides in the EPROM chip. The EPROM is inserted into a socket on the control board. The angled corner on the chip identifies the correct position for installation. A PLCC type extraction tool is needed to remove the chip from the socket.

The settings in the menus are saved in the RAM chip. Removing and reinstalling the RAM chip will restore the factory default settings in the menus. The RAM chip must be inserted with the notch towards the side of the socket with the notch.

Power is supplied to the 5 VDC terminal on the UVC3 board from the interface board. The operating voltage range for the control is 4.75 – 5.25 VDC.

Note: For installations with low voltage supply (210V or less) it may be necessary to wire the 16 VAC transformer on the low voltage tap. Low voltage supplied to the interface board, in turn reduces the voltage supplied to the UVC3 board and may cause intermittent power failure tripping or the control panel keys do not function when the machine is powered.

The UVC3 communicates with the control panel interface board through a USB Cable.

There are three sets of pins on the UVC3 board. Refer to the following chart to identify their function.

Note: Use Part No. 040084-001 CONNECTORPROGRAMING SHUNT to jumper pins.

Interface Boards

Both interface boards are the same for the shake and soft serve side. Ribbon cables provide the communication path between the UVC3 and the interface boards.

A 16 VAC transformer supplies the power for the interface boards at Terminals A and B. Each board has a 5 VDC output terminal block. Line voltage is connected to the interface boards (L1 and L2) to operate components in the machine on command.

There are four sets of pins (W2,W3,W4,W5) on each interface board. The pins on the soft serve board are inactive in the Model C602. The pins on the shake interface board function as follows:

W2 Installing a jumper resets the Brush Clean

W3 If the machine is in the AUTO mode,

installing a jumper will simulate the viscosity setpoint.

W4 Installing a jumper forces the start of the

Systems, Controls and Operations

Personality Boards

A Personality Board plugs into the interface board. The shake proximity sensor (torque coupling sensor) and the portion control pyro-electric board harness are connected to the shake personality board. The soft serve personality board monitors the amperage in one leg of power supplied to the beater motor.

Control Panel Interface Board

Pins labeled W1 on the face of the Control Panel Interface Board must have a jumper installed to enable the audible tone when a key is selected. (W1 is located next to the audible tone device, below the 5 VDC connectors.)

The interface board must have the insulator installed to shield the circuitry on the back of the board.

The Control Panel Interface Board (Dec Plate PCB) is fastened to the back of the tempered glass panel and communicates with the UVC3 through a USB cable.

The control panel has two 5 VDC power leads supplied to the board. One connection supplies power to operate the touch sensors and LED’s and the other 5 VDC connection provides power to communicate with the UVC3 control.

The Vacuum Fluorescent Display (VFD) plugs into a socket on the interface board. The potentiometer dial at the top of the board is non-functional. The VFD does not require a contrast adjustment.

Motor Speed Control

The motor speed control is powered by 5 VDC and receives data bit information through a 10 pin ribbon cable. The speed control transmits a modulated signal to the syrup motor, therefore the voltage cannot be accurately measured with a meter.

The syrup pump motors run at maximum speed in the prime mode.

The UVC3 Control calculates the motor speed setting in the syrup calibration mode and sends the information to the speed control.

Syrup Delivery

Shake syrup is stored in the lower front compartment. Each syrup flavor is delivered to the dispensing door by a peristaltic pump. Syrup can be pumped directly from disposable plastic jugs, stainless steel tanks, or adapted to syrup-in-bag dispensing. The proper syrup delivery rate is achieved by calibrating each syrup flavor.

A 24 VDC motor drives each peristaltic pump. In the AUTO mode, the UVC3 control regulates the motor speed necessary to dispense syrup at the calibrated

rate. The pump motors run at maximum speed in the SYRUP PRIME mode.

A relay is used to reverse the rotation of the syrup pump motor each time the pump operation is discontinued. The syrup flow must be momentarily reversed in order to drop the pressure in the line and close the duckbill syrup valve.

Refer to the Motor Setup section in the Service Menu, page 31 for motor and reverse time settings.

Model C602

Systems, Controls and Operations

Syrup Calibration

Calibrating the syrup flow should be performed weekly when the syrup system is cleaned. It is vital that the correct amount of syrup be incorporated into the frozen mix to obtain a quality shake.

To determine the rate of syrup flow, you will need a calibration cup indicating fluid ounces. The proper rate of syrup flow is 1 fl. oz. (30 ml) of syrup in 5 seconds. For Triple Thick Shake syrups, the proper syrup flow rate is 1 fl. oz. +/- 1/8 fl. oz. (30 ml +/- 4 ml) in 7 seconds. Once this rate is set, the correct amount of syrup will be blended with the shake base regardless of the size of shake served. Please note that syrup calibration is critical when changing the promotional 4th flavor syrup.

Calibration Procedure

Syrup lines must be properly primed with syrup to eliminate air in the line before the calibration procedure is performed.

Step 1

Shake Dispensing Alignment Procedure

There are five areas that must be properly aligned in the shake draw mechanism.

S Actuator Plate S Spinner Motor Bracket S Solenoid Valve S Spinner Motor S Spinner Coupling

All adjustments must be performed with the freezer door assembled and installed, with the hand screws secure. Tighten the hand screws in a criss-cross pattern so the door is drawn up flush on the cylinder face. (See Figure 95.)

Actuator Plate

The actuator plate (lifter) should be centered to fit in the draw valve slot. (See Figure 96.)

Figure 96

To adjust the alignment, perform the following steps:

Step 1

With the bumper access plate removed and the bumper screw loose, align the actuator with the slot inthedrawvalve(sidetosidealignment).

Step 2

Secure the bumper screw. Check to make sure the bottom of the solenoid plunger is secured to the actuator plate.

The actuator should slide easily into the draw valve slot when the freezer door assembly is installed. (See Figure 97.)

Spinner Motor Bracket

The actuator plate should ride gently against the rear guide post.

The guide post is mounted underneath the spinner motor bracket. (See Figure 98.) Moving the bracket forward brings the guide post forward. When properly aligned, the actuator should move freely without any tension on the guide post.

To adjust the solenoid height, use the Solenoid Adjust Tool Kit Assembly (X59702) and perform the following steps:

Step 1

Place the power switch to the OFF position and disconnect power to the machine.

Make sure the power switch is in the

OFF position. Failure to follow this instruction may

result in severe personal injury from hazardous moving parts.

Step 2

Remove the front control panel.

Step 3

Loosen the two 7/16” nuts that secure the draw solenoid to the mounting bracket. The solenoid spring tension will push the coil to the top of the adjustment slots in the bracket.

Figure 98

To adjust the alignment, perform the following steps:

Step 1

Loosen the four hex head screws that secure the spinner motor bracket to the control channel bracket.

Step 2

Slide the bracket forward or backward to the correct position and secure the four screws.

Solenoid Valve

The solenoid valve should be vertically aligned so the plunger moves freely in the coil without side load. The height of the solenoid should be adjusted to raise the draw valve to the top of the product port in the freezer door.

With the spinner blade and the driven spinner removed, and the draw valve in the raised position, look inside the freezer door. The bottom of the draw valve should be located at the top of the product entry port.

Step 4

Remove the restrictor cap, spinner blade, and the driven spinner from the shake door.

Step 5

Rinse the area below the draw valve.

Step 6

Lubricate the two o-rings and install the Solenoid Adjust Tool into the door spout. Lift the draw valve to insert the tool into the door. Install the restrictor cap to retain the tool with the draw valve in the raised position. (See Figure 99.)

If the valve is too high or too low, the height of the solenoid will need adjustment.

Model C602

Figure 99

Systems, Controls and Operations

Step 7

Lower the solenoid until the top of the plunger contacts the top surface (stopping point) inside the coil body. (See Figure 100.) Make sure the solenoid is aligned vertically and then retighten the two 7/16” nuts to secure the solenoid.

To adjust the alignment, perform the following steps:

Step 1

Loosen the four screws that secure the spinner motor to the bracket. With the freezer door assembly installed, insert the spinner blade into the coupling.

Step 2

Position the motor so the spinner shaft is centered with the coupling.

Step 3

Tighten the two front screws.

Figure 100

Step 8

Remove the restrictor cap and tool.

Step 9

Sanitize, lubricate, and reinstall the driven spinner and spinner blade. Install the restrictor cap.

Step 10

Install the front control panel and restore power to the machine.

Step 11

Dispense several shakes to check for proper draw valve performance.

Spinner Motor

The spinner motor shaft must be centered in the draw valve. The spinner blade shaft must insert into the center of the spinner coupling. (See Figure 101.)

Step 4

Remove the door to tighten the rear screws.

Spinner Coupling

The coupling must be adjusted so the spinner blade is recessed 1/32” (0.8 mm) or less in the bottom of the door spout.

To adjust the alignment, perform the following steps:

Step 1

Assemble the freezer door.

Step 2

Loosen the top screw that secures the coupling to the spinner motor shaft.

Figure 101

Systems, Controls and Operations

Step 3

Position the coupling so the bottom of the spinner is recessed 1/32” (0.8 mm) or less in the bottom of the door spout.

Step 4

Retighten the coupling screw.

Troubleshooting

Bacteria Troubleshooting

Periodic product sampling is taken by a sanitarian. Bacteria counts should not exceed the following figures:

Standard Plate Count (SPC) 50,000..

Coliform 10....................

If the counts exceed the numbers listed, steps should be taken to locate the cause. Failure to solve the high counts will result in an unsafe product for

CAUSE OF CONTAMINATION PREVENTION

1. Human contamination. a. Wash hands and arms past elbows.

consumption. Educate the operator about how to prevent high bacteria counts.

Note: High bacteria counts in soft serve yogurt is normal and necessary. Coliform, however, cannot be accepted in any product. The following information will help solve high coliform count problems.

If sample results indicate a problem, one of these areas may be a source of contamination.

b. Wear rubber gloves if cuts or skin conditions exist.

c. Wash hands periodically throughout the day.

a. Provide the proper brushes.

b. Brush clean all parts and components thoroughly.

Ignoring this will allow formation of milkstone, a porous substance which will house bacteria and can lead to contamination of fresh mix.

3. Worn, damaged, or cracked parts. a. Provide a food grade lubricant (Example: Taylor

Lube).

b. Inspect o-rings for holes or tears. O-rings, seals and

other wear items must be supplied by the freezer company to meet food industry standards.

c. During the operating hours, periodically inspect the

rear drip pan for excessive leakage.

CAUSE OF CONTAMINATION PREVENTION

4. Improper cleaning and sanitation procedures. a. For cleaning procedures, scrub the sink and strainers

thoroughly before each use. The level of solution in each basin must allow the largest component to be submerged. Sanitize and prime the freezer prior to freezing the product. After sanitizing a freezer, use fresh mix to flush remaining sanitizer from the freezing cylinder.

b. Provide the proper brushes, lubricants, and single

service towels.

c. Store sanitizer in a cool, dry place. Use chemicals

according to their labels.

d. Use a few good employees to follow the cleaning

procedure correctly and consistently. Allow the employee uninterrupted time to complete the cleaning procedure.

e. Hold sanitizing solution in the hopper and the freezing

cylinder for five minutes.

f. Wash and sanitize the tube of lubricant; after each

use, always recap the tube.

g. Parts, components, and brushes should be air-dried

overnight. Never store the equipment in the storage cooler.

h. Do not neglect daily cleaning practices: wipe the

external areas of the freezer periodically throughout the day, remove the design caps and sanitize the area, check the drip trays and splash shield.

5. Mix stored improperly. a. Rotate stock to use older date code mix first. Shelf life

of mix is normally 10 days.

b. Mix must never be stacked outside or under direct

sunlight while waiting to be placed in the cooler.

c. Place the mix directly in the cooler. Always leave one

inch between the mix and other products to allow air to circulate around the product.

d. Mix must not remain at room temperature for long

periods of time.

e. Hopper storage must maintain a temperature of 40_F

(4.4_C). Storage temperatures above 45_F will allow cell division in as little as one hour.

f. Once the mix is placed in the hopper, covers must be

properly installed to maintain adequate refrigeration and to prevent airborne contaminants from entering the mix.
