3 TheoryofOperation

SELV Series electric fryers utilize a welded, stainless steel fryvat that is directly heated with high efficiency, ribbon style heating elements. Ribbon style elements offer a lower watt density per square inch and are gentler on the oil. The elements rotate upward for easy cleaning. In full-vat units, heat demand to the elements is regulated by one electromechanical contactor. In split-vat units, each element bank has its own contactor to independently control each vat. All fryers in this series are equipped with 24 V AC control circuits, and the elements can be configured to accommodate a wide range of electrical supply.

L22-393 R0 Page 12

3.1 The Heating System

A hi-limit device located in the fry vat provides an additional level of operator safety. If the high limit is satisfied that the fryer is operating within design parameters, a “side on” contactor will close and stay closed so long as the cooking oil temperature stays below a specified limit. This safety circuit minimizes the operations of the “side on” contactor to insure it can open in the unlikely event of a run away condition. The “side on” contactor is wired in parallel with the “heat demand” contactor to deliver main power to the heating elements. The heat demand contactor is controlled via the I12+ control board which responds to input from a thermistor located in the fryvat. When the thermistor transmits a temperature reading below the desired cook temperature, the I12+ closes the heat demand contactor completing the circuit to supply electrical energy to the hating elements until the oil temperature matches the desired cooking temperature. Should the high limit trip, it cannot be reset until the oil temperature falls below the hi-limit threshold, so the unit needs to cool. The cause of the hi-limit tripping should be investigated and corrected prior to putting the fryer back into service.

The unit is connected to line voltage:

If Fuse F1 on the relay board is good:

 The A.C. indicator is illuminated.

 The controller is supplied with 24 VAC.

 With the drain valve handle closed, the proximity switch supplies 24 VAC to the drain valve interlock

(DVI) input at the controller.

 24 VAC is at the Side On (SO) relay COM contact.

The controller is turned ON:

 The SO indicator on the relay board is illuminated.

 The SO relay is energized, closing the circuit.

 The safety (SO) contactor energizes if the hi-limit is not tripped.

3.2 Hi-Limit System

If the hi-limit trips:

The SO and HD contactors lose 24 VAC supply and the HFB loses 24 VAC.

The computer displays “HEATING”.

The HD lamp is illuminated on the Back-up T-stat and the HFB lamp is not illuminated.

After the hi-limit resets (unit cools to 375°F ±20°F (191°C ±20°C)), turn the controller off and then back on for the unit to heat.

L22-393 R0 Page 13

3.3 Auto Filtration Boards

All fryers in this series have an Auto-Filtration Board (AFB) located in the component box behind the control bezel. The AFB provides a “bus” between the controller and the fryer's individual components without requiring additional wiring by using a communication protocol over a twisted pair, and allows the controller to execute commands from one central point. The heat control circuit is show below in Figure

1. This is the bottom left corner of the AFB. For a split vat, this is duplicated on the bottom right hand corner.

Figure 1 - Bottom left corner of Auto Filtration Board

L22-393 R0 Page 14

Figure 2 - Auto-Filtration Board (AFB)

L22-393 R0 Page 15

3.4 Thermostats

SELV Series electric fryers have temperature probes located between the heating elements in the center, bottom of the vat. In a full vat, the temperature probe is on the right bank of elements. There is always one in each vat, full or split. SELV fryers, like all Solstice series fryers, use a thermistor style temperature probe. In this type of thermostat, the probe resistance varies directly with the temperature. That is, as the temperature rises, so does resistance. Circuitry in the controller monitors the probe resistance and controls heat demand contactor when the resistance exceeds or falls below programmed temperatures (setpoints). SELV Series electric fryers are also equipped with a high-limit thermostat. In the event that the fryer fails to properly control the oil temperature, the high-limit thermostat prevents the fryer from overheating to the flash point. The high-limit thermostat acts as a normally closed power switch that opens when exposed to temperatures above 425°F to 450°F (218°C to 232°C).

3.5 Fryer Sequence Operation

The SELV fryer components function in specific order of operation. Knowing and understanding the sequence of fryer and components operation enables you to diagnose equipment failure more accurately.

3.6 Filter System (Manual Filtration Only)

Pulling the BLUE drain valve handle will:

Open the drain at the bottom of the fry vat

Open the “Drain Valve Interlock” (DVI) magnetic switch disabling the heating system during filtration.

!WARNING!

Inspect the filter pan prior to pulling the BLUE DRAIN VALVE HANDLE to insure it is empty. If the filter pan has visible oil, opening the valve will result in hot oil overflow onto the floor resulting in slipping hazards, fall related injuries, serious burns or death.

Push handle in to close Drain and enable DVI.

Pulling the RED (If Equipped) return valve handle:

 Opens the return valve to that vat.

 Closes the pump proximity switch causing the “pump run” relay to be energized.

 The pump motor begins to run.

Closing the return valve handle de-energizes the relay and the pump motor stops running and the return valve closes.

The pump system is equipped with a circuit breaker which de-energizes the system and the heat tape (If equipped) in the event of over current. The circuit breaker must be in the “ON” position for the pump and heat tape to operate.

Circuit Breaker should remain in the “ON” position at all times.

NOTE

Pulling the BROWN waste oil valve will: (If equipped):

Divert oil flow from the pump to the fry vat to user supplied waste oil plumbing through a Pitco supplied three way valve.The return piping system may be provided with optional heat tape to prevent solidification of solid shortening. The heat tape is low wattage and is on constantly to maintain liquid shortening in the line.

L22-393 R0 Page 16

3.7 Basket Lift (Optional)

The basket lift is a self contained unit that requires a 120V, 208V, or 240V supply. With most fryer configurations, the power is supplied from the entrance box at the back of the fryer, but some configurations require power directly from a wall outlet.

When power is supplied to basket lift assembly, the baskets lift to the up position.

The baskets lower with a 24 VDC output from the controller.

The basket lift control voltage is supplied from the controller

The basket lift operational voltage is supplied from the line voltage supply that powers the transformer in the basket lift assembly.

3.8 Auto Top Off – ATO (Optional)

If equipped, the optional Auto Top Off (ATO) adds small doses of oil from the “Jug in Box” or JIB when low oil conditions are detected. During frying, small amounts of oil are absorbed (called “drag out”) by the food and removed from the fryer. These small amounts eventually lead to replenishment with a “Top Off” event.

The fryer cannot be filled from empty with the Auto Top Off option.

The ATO uses the filter pump to move oil from the JIB to the fry vat when low oil conditions are sensed. A linear actuator redirects the pump flow from the JIB during a Top Off event.

The ATO doesn’t not operate during a cook cycle to keep the oil hot during cooking. Adding room temperature oil during cooking would negatively impact the cook cycle and product.

The ATO probe is located on the rear wall of the fry tank as pictured below:

The ATO probe plugs into the Auto Top Off relay board behind the front control bezel.

The following conditions must be met for the ATO event to occur:

The vat must be in idle condition, not cooking or melting, with display showing “Ready” or “Drop”. This display typically shows when the vat is within 20°F of cooking set-point.

L22-393 R0 Page 17

When the cooking control shows Ready, the oil level probe will take time to detect the low level condition. The lower the level the faster the response. The reverse is also true. Modestly low levels take longer to resolve. (< 3/8” below probe). Levels ½” below probe should detect in 3-1/2 minutes or less.

Drain Valve Actuator (top) with Drain Valve (below) 1 Linear Actuator 1

Food debris, or oil caked onto probe may prevent ATO operation. Occasional probe cleaning when vat is empty and cool is recommended.

Top off does not occur when the control is Off, Melting, Cooking, or Heating.

3.9 Automated Filtration (Optional)

If equipped with an Automated Filtration system, the filtration works like any other Solstice Fryer except the manual handles (blue and red) are replaced with actuators (show above) to drain the fry vat and return oil to fry vat after filtering.

The Automated Filtration system does not actuate “automatically”, user input is required.

The actuators for the drain valve and return valve can be manually operated through the I12 computer. (See Section this manual,9)

When a pre-determined threshold (typically a user programmed number of cooks) is reached, the operator can be prompted to filter the cooking oil. Upon successful operator input, the system:

Begins an automated filtration process that first opens the drain valve and drains the oil into the filter pan.

Shortly after the drain valve opens, the linear actuator opens the return valve and the filter pump actuates. The filtering process operates for a pre-defined period of time (user programmable)

The drain valve closes and the pump continues to run, returning the freshly filtered oil to the fry vat.

When timer reaches zero all the oil has been pumped back to the fry vat, the pump turns off and the return valve closes.

The operator is queried to insure the vat is full. If the operator responds “NO”, the filter pump turns on for 20 seconds and the return valve is opened to pump any remaining oil from the filter pan. When the operator responds “YES”, the fryer turns itself off and must be re-energized by the operator pressing the “ON” key to restore power and begin frying.

23 TroubleshootingandProblemIsolation 24 ComponentTroubleshooting

The following sections provide troubleshooting information for the fryer components.

24.1 Probe

The resistance of the probe changes as the temperature changes. The resistance decreases as the temperature rises.

The lower the temperature, the greater the resistance change is per degree of temperature change. As the temperature approaches the working range of the probe, the resistance change becomes more linear.

Is the probe bad?

Neither probe wire should have any connection to the appliance frame. Typical resistance



reading would be >4 Meg ohms. Probe wires should not be shorted, less than 100 ohms reading.



Prove wires should not be open circuit, greater than 350K ohms reading.



If the probe is suspect, check it's resistance at the current vat temperature. Measure the temperature with a thermometer as close to the probe tip as possible. Refer to Probe Resistance Chart on page 94. Within the cooking range of 325 to 375°F, the resistance should be within 30 ohms of the values in Probe Resistance Chart for the temperature measured. At lower temperatures (< 325°F), expect larger variances as the probe response becomes increasingly non-linear. Offset Adjustments

Static temperature offsets between the probe tip and center oil cooking temperature can be zeroed out with the cooking control’s offset setting. This adjustment forces the heating system to compensate for the difference between the probe tip temperature and center oil temperature. The displayed temperature is then the center oil temperature. Refer to the cooking control manual "Offset Temperature Display" for details on making this adjustment.

Allow the oil to cool and check the probe resistance at a lower temperature. Looking at the probe resistance chart, a greater resistance variation is tolerated at a lower temperature.

24.2 HD Contactor

The HD contactor has a 24 VAC coil and energizes when the correct voltage is supplied to the coil. When energized, the contacts close, allowing current to flow through the elements. The coil resistance is 3.3 Ω +/- 1.

24.3 Side On Safety Contactor

Check the coil with an Ω meter. The resistance should be approximately 5.5 Ω to 7 Ω out of circuit. If it does not have this resistance, it should be changed.

24.4 Context Removed

L22-393 R0 Page 75

24.5 Drain Valve and Return Valve Switches

These switches are a magnetically operated proximity switches. When the BLUE drain valve handle is moved to the open position, the actuator moves away from the switch causing the switch to open. When the drain valve is closed, the switch closes.

Opening the RED filter return valve handle closes the proximity switch, causing the “pump on” relay to be energized; the pump begins to pump. Closing the filter return valve handle opens the proximity switch, causing the relay to de-energize and the pump to stop pumping. These switches can be checked with a Ω meter. When the switch is closed, there should be near zero resistance. The normal gap between the actuator and the sensor switch on the valve handle is 1/8 inch to 1/4 inch (3 mm to 6 mm).

24.6 Transformer

The transformer is a multiple AC input voltage and 24 VAC output voltage. It can be checked by reading the input and output voltages. A quick check for 24 VAC is done at the relay board behind the front panel. The AC indicator is illuminated if the F1 fuse is good and the board is receiving 24 VAC. See Section 6.1 Diagram Identifying Terminals for Second Resistance

24.7 Elements

Each element has three coils. Check all the element coils out of circuit with an Ω meter. The resistance should correspond to the following:

208 Volt Element 14.1-16.4 Ω 240 Volt Element 18.8-21.8 Ω

If the resistance is outside of the rating, the element needs to be changed. Also check for continuity to ground on each end of the suspect element. There should be no continuity to ground.

L22-393 R0 Page 76

24.8 Relay Board

NOTE: J connectors are marked on the relay board.

With 24 VAC supplied to pin #2 at connector J35 and a good F1 fuse, the relay board has a 24 VAC output at pin #2 on connectors J33 and J34 and the AC indicator is illuminated.

When the board receives a 24 VDC SO input at pin #7 on connector J31 or J33, the SO indicator is illuminated, the SO relay is energized, and there is a 24 VAC output at pin #4 on connector J32.

When the board receives a 24 VDC HD input at pin #6 on connector J31 or J33, the HD indicator is illuminated, the HD relay is energized and there is continuity between pin #1 and pin #2 at connector J32.

24.9 Computer Control

NOTE: All controller test points are at connector P/J1 (closest connector to the controller).

With 24 VAC supplied to pin #1(24 VAC supply) and pin #5 (24 VAC input from DVI), the display reads “READY”, “HEATING” or “MELT L/S”.

When the controller is turned on, there is a 24 VDC output at pin #9 (SO).

When the controller calls for heat, there is a 24 VDC output at pin #8 (HD) and a 24 VAC input at pin #6 (HFB). If the HD contactor does not pull in, this indicates a break in the HD circuit.

To correct, do the following:

Check the hi-limit switch. Is it open or tripped?

Check the HD relay on the relay board. Is the HD relay energized, continuity through COM and NO

contacts?

If display reads “PROBE OP” “OPEN”, Ω test the temperature probe. Check the wires and connectors between the probe and controller for continuity.

If display reads “SYSTEM” ‘FAILURE”, Ω test the temperature probe, and the wires and connectors between the probe and controller for a short.

If display reads “DRAINING” “TURN OFF”, verify that the drain valve is closed, check the proximity switch on the drain valve (If Equipped), turn the fryer off, and then turn the fryer on.
