ELECTRIC COUNTER TOP TILTING KETTLES - ELECTRICAL OPERATION
SEQUENCE OF OPERATION
1. Conditions.
A. Kettle connected to correct voltage supply and is properly grounded.
1) 120VAC potential across X2 and X1 on secondary of main transformer.
B. Power switch and light (1LT) (amber) are off.
C. Low water light (2LT) (red) is off.
D. Pressure switch (1PAS) contacts closed.
E. Temperature dial at lowest setting (potentiometer fully CCW).
1) Internal relay contacts N.O. are open.
F. Kettle at room temperature and in the full upright position.
2. Power switch turned ON.
A. Power light (1LT) (amber) comes on.
B. Power from secondary of main transformer to control circuit thru pressure switch (1PAS) N.C. contacts.
3. Water level control (WLC) energized.
A. WLC LLCO probe satisfied (fluid in kettle reservoir jacket at proper level).
1) LLCO LED comes on.
B. WLC LLCO N.C. contacts open. Low water light (2LT) (red) remains off.
C. WLC LLCO N.O. contacts close.
1) Limiting contactor (1CON) energized (power to one side of heating elements).
2) Power to temperature controller.
4. Set the temperature dial to call for heat (warm/simmer/boil).
A. 120VAC output from T8 on temperature controller.
1) Heat light (3LT) (amber) comes on.
2) Regulating contactor (2CON) energized and heating elements are powered.
5. Kettle reaches set point temperature.
A. Voltage output removed from T8 on temperature controller.
1) Heat light (3LT) (amber) goes out.
2) Regulating contactor (2CON) de-energized and powered is removed from heating elements.
6. Kettle heat cycles with the temperature controller.
7. Kettle tilted to empty contents.
A. WLC LLCO probe no longer satisfied (fluid in kettle reservoir jacket not in contact with probe). Water
level control (WLC) LLCO relay de-energized.
1) LLCO LED turns off.
B. WLC (LLCO) N.C. contacts close and low water light (2LT) (red) comes on.
C. WLC (LLCO) N.O. contacts open and power is removed from heating circuit.
8. Kettle returned to upright position. Water level control (WLC) circuit returns to normal operation and heating
cycle resumes. Kettle heating will continue to cycle with the temperature controller until the temperature dial is
turned fully CCW or power switch is turned OFF.
