ELECTRIC COUNTER TOP TILTING KETTLES - ELECTRICAL OPERATION
ELECTRICAL OPERATION
COMPONENT FUNCTION
Water Level Control (WLC LLCO) .......... Low water level control. Monitors condition of the WLC LLCO
water level probe. Protects kettle from a low water condition in
the reservoir jacket and removes power from heating circuit
when kettle is tilted.
Probe, Water Level (LLCO) .............. Low Level Cut-Off (LLCO) probe connected to WLC (LLCO).
Controls power to heating circuit.
Contactor (1CON) Limiting ............... Connects one side of heating element to power. Energized
whenever WLC (LLCO) coil is energized.
Contactor (2CON) Regulating ............. Connects heating element to power. On constantly when
temperature controller is calling for heat.
Element, Heating ....................... Heats reservoir jacket fluid. The heat in the fluid is then
transferred to kettle.
Fuse, (1FU & 2FU)....................... Slow blow 3A fuse. Located on primary side of main transformer
(1T). Protects control circuitry from over-currents.
Switch (1PAS), Pressure ................. Pressure cut-out protection for the reservoir jacket. Range is
between 38 to 42 PSI. Removes power from control circuit if
pressure in the jacket rises above switch setting.
Transformer (1T), Main .................. Step down transformer from line voltage to 120VAC control
circuit voltage.
Switch (1S), Power ..................... Controls 120VAC to kettle control circuit
Temperature Controller .................. Cycles power to regulating contactor (2CON) to maintain the set
point temperature. An external set point potentiometer is used
for temperature adjustments.
Lamp (1LT), Power ..................... Amber (AM) colored lamp. On when power switch is on.
Lamp (2LT), Low Water .................. Red (RD) colored lamp. On when water level in the reservoir
jacket drops below water level (LLCO) probe.
Lamp (3LT), Heat ....................... Amber (AM) colored lamp. On when temperature controller is
calling for heat.
