ELECTRIC COOKER MODELS 17EC, 17ECS, ESW AND EWBS CHAPTER 6: 17EC/17ECS SERVICE PROCEDURES & PARTS

6.1Functional Description

The 17EC Electric Cooker contains a 16.5-gallon (62.5-liter) stainless steel cookpot. The water in the cookpot is heated by a pair of 8.5-kilowatt 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 17EC is identical in appearance to the SMS

IIIcomputers used in other model lines, but differs internally. Use only P/N 106-0385 SMS III computers on this equipment. The 17EC 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 17ECS model has 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 anytime 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. (See Chapter 3 for instructions on adjusting the 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 drive 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.
