ELECTRIC COOKER MODELS 17/8SMS, 17/8BC, 17/8C

CHAPTER 1: SERVICE PROCEDURES

1.1 Functional Description

The 17kW Pasta Magic Electric Cooker contains a 16.5-gallon (62.5-liter) stainless steel cookpot. The 8kW unit has a 8.75 gallon (33 liter) cookpot. The water in the cookpot is heated by a pair of

heating elements. Electrical power to the elements is controlled by a solid-state SMS III Spaghetti Magic computer specifically modified for this application. NOTE: The SMS III computer used in

the Pasta Magic is identical in appearance to the SMS III computers used in other model lines, but differs internally. The SMS is equipped with a basket lift, and also features automatic filling (AutoFill) and automatic skimming (AutoSkim). This model also has a swing-away jointed faucet. The SMS and BC models have an attached 16.5-gallon (84.1-liter) rinse tank.

Turn the Master Power Switch ON and press the computer Power switch. A logic circuit checks the water level by looking for a ground at the upper water-level sensor. A normally closed solenoid valve opens if no ground is seen, indicating water is below the sensor, and water enters the cookpot. The unit enters the Simmer mode when the heating elements are covered (indicated by grounding of the low-water sensor). The cookpot continues to fill until water reaches the upper water-level sensor and the solenoid closes. The cooker stays in Simmer mode until the Boil mode switch is pressed or the unit is turned off. The water solenoid valve opens when the water level is below the upper water-level sensor.

Logic circuits in the computer monitor the temperature and cycle power on and off to maintain the simmer setpoint. The cooker also has a high-limit safety. If the cookpot fails to refill and the water level drops below the low-water sensor, the high-limit will open, cutting off power to the elements, when the element temperature reaches 400 ±15ºF.

Pressing the Skim switch activates the AutoSkim feature. A logic circuit in the computer opens the solenoid valve in the water supply line for three seconds every minute until the option is turned off by again pressing the Skim switch.

The operator enters a cooking time by pressing the number pads on the computer. The computer counts down the cook cycle time when the Start switch is pressed. When the computer times out, an alarm sounds briefly, then the timer reverts to the last time entered.

Logic circuits in the computer also activate the basket lift motors when the Start switch is pressed, lowering the basket into the cookpot. A pair of motors drives the basket lift arms down until a cam attached to the left motor loses contact with a roller-activated microswitch and power to the motors is cut. When the computer times out, the logic circuits reverse the switch positions so that the motor circuit is again completed and the motors are restarted, raising the basket from the cookpot. The cam again makes contact with the microswitch at the raised position, cutting power to the motors and stopping the lift in the up position.

1.4 Troubleshooting NOTE: The 24VAC power to the electronic components of this system is controlled by the master

ON/OFF switch located on the front of the contactor box. If this switch is in the OFF position, none of the system components will function.

DANGER

The master ON/OFF switch does not disconnect this equipment from the electrical power source! Line voltage is supplied to the transformer and to the basket lift motors as long as the unit

is plugged in.

Problems with this equipment may be grouped into five broad categories:

1. Failure or malfunction of a 24VAC power-supply system component.

2. Failure or malfunction of the computer.

3. Failure or malfunction of an Autofill/AutoSkim system component.

4. Failure or malfunction of a water heating system component.

5. Failure or malfunction of a basket lift system component.

Sections 1.4.1 through 1.4.5 briefly explain the functioning of each of the systems mentioned above. Section 1.4.6 contains troubleshooting guides that provide systematic procedures to isolate and identify the specific source of a problem. A wiring diagram is located at the end of the chapter.

1.4.1 How the Power-Suppl y System Works

Line voltage is supplied to the system via a power cord that is plugged or hard-wired into the store’s electrical service. The power cord is attached to a three-lug delta-power terminal block. One set of wires delivers line voltage from the load side of the block to Terminal 1 of each of the solid-state relays. A second set of wires delivers line voltage through a pair of fuses to the 24VAC transformer and to the basket lift relay. Line voltage for one side of the basket lift motor circuit is tapped from a “piggy-back” terminal on the line side of the transformer. Line voltage for the other side of the circuit is supplied via the basket lift relay. 24VAC is supplied to the equipment by placing the master ON/OFF switch in the ON position, which grounds the transformer.

1.4.2 How the Computer Works

The SMS III computer provides the interface between the operator and the system components. The computer is powered by 24VAC supplied through Pins 1 (hot) and 2 (ground) of the 15-pin wiring harness. Internal circuitry senses the water level, water temperature, and element temperature. Depending upon the conditions sensed, the computer energizes or de-energizes the solenoid valve to control water level and the heating elements to control water temperature. The computer also controls the lowering and raising of the basket lift, and activates an audible alarm, indicating a cooking cycle is complete. A rectifier in the computer coverts 24VAC to the 24VDC required by the basket lift relay and the solid-state heating relays. The computer signals for heat via Pin 4, grounds the solenoid valve via Pin 6, and senses water level via pins 7 (low) and 9 (full). The temperature probe connects to Pins 13 and 14. The basket lift relay connects to pins 10 and 12. The sound device connects to pin 11.

1-12

1.4.3 How the Autofill/AutoSkim System Works

The heart of the automatic filling (Autofill) system is a normally closed solenoid valve that opens when 24VAC is applied.

The ground for the solenoid is supplied (via pin 6 of the computer wiring harness) so long as the upper water-level sensor is not in contact with the water in the cookpot. When the water in the cookpot reaches the upper water-level sensor, the sensor is grounded. This causes the computer to break the solenoid ground, closing the valve. Starch or lime build-up on the upper water-level sensor may keep a ground from forming, therefore always make sure the sensor is clean and its lead (pin 9 of the computer wiring harness) is firmly connected. Also, in order for the ground to form, there must be some mineral content in the water (pure water is non-conductive). Consequently, the units will not operate with distilled water. If distilled, highly filtered, or purified water is used, add ⅛-cup of baking soda to the water each time the cookpot is emptied and refilled.

When the AutoSkim feature is activated by pressing the skim switch on the computer, a logic circuit in the computer automatically opens the solenoid valve for three seconds every minute until the switch is again pressed. If the Autofill feature is working properly, failure of the AutoSkim feature will be due to a malfunctioning computer and not the solenoid valve. (Proper operation of the Autofill feature can be determined by draining water from the cookpot until the water level is below the upper water-level sensor. If the solenoid valve opens and then closes when the water in the cookpot again reaches the upper water-level sensor, the Autofill feature is working properly.)

1.4.4 How the Water Heating System Works

To prevent energizing the heating elements when there is no water in the cookpot, these units are

equipped with a low-water-level sensor. This sensor must be grounded by contact with water in the

cookpot before the control circuitry will apply power to the elements. Starch or lime build-up on the low-water-level sensor may keep the ground from forming, therefore always make sure the sensor is clean and its lead (pin 7 of the computer wiring harness) is firmly connected. In order for the ground to form, there must be some mineral content in the water (pure water is non-conductive). Consequently, the units will not operate with distilled water. If distilled, highly filtered, or purified water is used, add ⅛-cup of baking soda to the water each time the cookpot is emptied and refilled.

In addition to the low-water-level sensor discussed above, the water heating system has six more parts: the high-limit thermostat, the temperature probe, the contactor, the element, a group of three solid-state relays, and the computer.

The high-limit thermostat functions as a normally closed switch. If the water in the cookpot falls

below the low-water-level sensor but the sensor remains grounded (for whatever reason), the highlimit switch will open when the element temperature reaches 400ºF ±15 (204ºC ± 9). This cuts power to the contactor coil and thus to the element.

The temperature probe is used only when the unit is in the simmer mode. When the operator

selects the simmer mode, logic circuits in the computer monitor the temperature of the water and cycle power to the element to maintain the the programmed temperature.

The contactor is the terminal block to which the element leads are connected and where contact is

made between the leads and the line voltage. Built into the contactor is a 24VAC coil that energizes

1-13

when the master ON/OFF switch is placed in the ON position. When it energizes, contact is made between the incoming line voltage and the element leads, and line voltage is supplied to one side of

the element circuit. The solid-state relays control the supply of line voltage to the other side of the

element circuit. The relays are closed when the computer is calling for heat and open when it is not.

The element is a resistive heating device. That is, when voltage is applied to the element, the

element gets very hot due to its resistance to current flow through it. The heat generated is transferred directly to the water.

The computer is the interface between the operator and the other components of the equipment. In

the water heating system, its function is to control the application of line voltage to the heating element via the solid-state relays.

When in the Simmer Mode, the signal from the computer is continuous, the solid-state relays are

continuously closed, and line voltage is applied to the elements until the simmer setpoint (195ºF/90.6ºC) is reached.

When in the Boil Mode, the signal from the computer is continuous for approximately the first 40

seconds, then changes to a series of on-off pulses of equal duration. The solid-state relays close and open in response to the signal from the computer, and line voltage is applied to the elements accordingly. (The pulsing of the line voltage to the elements prevents the water in the cookpot from reaching a vigorous, roiling boil. This, in turn, minimizes the formation of starch foam. An added benefit of the pulsing is reduced electrical power consumption.)

1.4.5 How the Basket Lift System Works

When the Start switch is pressed to start the cooking cycle, logic circuits in the computer activate the basket lift motors, lowering the basket into the cookpot. As the motors drive the basket lift arms down, a cam attached to the left motor eventually loses contact with a roller-activated microswitch and power to the motors is cut. When the computer times out, logic circuits reverse the switch positions so that the motor circuit is again completed and the motors are restarted, raising the basket from the cookpot. At the fully raised position, the cam again makes contact with the microswitch, cutting power to the motors and stopping the lift in the up position.
