C24EO SERIES STEAMER - ELECTRICAL OPERATION
ELECTRICAL OPERATION
COMPONENT FUNCTION
Buzzer . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Creates audible signal when timed cook cycle is complete and when a low water condition exists.
Limiting Contactor (1CON) . . . . . . . . . . . . . . . Supplies line voltage to heating element assembly. Energized whenever Power Switch (1S) is on and High Limit Thermostat (1TAS) and Low Water Thermostat (2TAS) are closed.
Regulating Contactor (2CON) . . . . . . . . . . . . . Supplies line voltage to heating element assembly. Energized whenever Hold Thermostat (3TAS) is closed or the temperature controller calls for heat.
Heating Element . . . . . . . . . . . . . . . . . . . . . . . . Located below water reservoir. Heats water to produce steam. Fuses (1FU & 2FU) . . . . . . . . . . . . . . . . . . . . . . Protect control circuitry from
Low Water Light (1LT) . . . . . . . . . . . . . . . . . . . Amber (AM) colored light. Lit when Low Water Thermostat (2TAS) senses water level is too low inside steamer.
On Light (2LT) . . . . . . . . . . . . . . . . . . . . . . . . . | Amber (AM) colored light. Lit when Power Switch (1S) is on. |
Cook Light (3LT) . . . . . . . . . . . . . . . . . . . . . . . | Red (RD) colored light. Lit when High Limit (1TAS) and Low |
| Water (2TAS) thermostats are closed, door is closed and timer |
| is set. |
Relay (K1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Controls Regulating Contactor (2CON) based on input from Hold Thermostat (3TAS) and Temperature Controller. Does not allow Timer Motor to run while Hold Thermostat (3TAS) is closed.
Relay (K2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Latches Power Switch (1S) circuit. Turns on Low Water Light (1LT) and Buzzer when steamer is low on water.
Relay (K3) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Controlled by Power Switch (1S). Keeps Buzzer from sounding and Low Water Light (1LT) off when switch is in off position.
Power Switch (1S) . . . . . . . . . . . . . . . . . . . . . . Rocker switch that turns steamer OFF and ON (momentary on). Switch also resets Low Water Light (1LT) and Buzzer.
Door Switch (1SW) . . . . . . . . . . . . . . . . . . . . . | Removes power from a portion of the steamer control circuit |
| when door is opened. |
High Limit Thermostat (1TAS) . . . . . . . . . . . . . Protects steamer by removing control circuit power if the heating element assembly temperature goes above 495EF.
Low Water Thermostat (2TAS) . . . . . . . . . . . . | Monitors presence of water inside steamer. |
Hold Thermostat (3TAS) . . . . . . . . . . . . . . . . . | Controls temperature of cavity for |
| 175E F). Disables timer countdown if cavity temperature is too |
| low. |
Timer Motor . . . . . . . . . . . . . . . . . . . . . . . . . . . . | Counts cook time of product when time is dialed. Energizes |
| buzzer and |
| expires. |
Temperature Control . . . . . . . . . . . . . . . . . . . . | Monitors temperature probe and cycles power to regulating |
| contactor (2CON) for steam generation. |
Temperature Probe . . . . . . . . . . . . . . . . . . . . . | Senses cooking compartment temperature at steam vent and |
| sends a corresponding DC voltage back to the temperature |
| control |
Transformer (1T) . . . . . . . . . . . . . . . . . . . . . . . | Steps down line voltage to 120VAC control circuit voltage. |
