Compartment Thermostat (electronic key pad units only)
The compartment thermal switch delays timer countdown until compartment
temperature is above 190°F. This compensates for frozen or partially thawed food.
Opening the door during the cooking cycle also can require additional cooking
time. The compartment thermal switch controls the pause circuit in the timer.
Mechanical Timer
Operating the dial timer is explained in Chapter 3. After selling the dial, the timed
steaming cycle starts. Timer contacts L1-T1 close to energize the condenser
solenoid and heater contactor. See Figure 5-19. Contacts L1-T3 open to enable the
3-second timer. When time elapses and the dial reads 0, timer contacts L1-T1 open
to de-energize the condenser solenoid and heater contactor. Contacts L1-T3 close
to supply power to the 3-second timer and buzzer.
3-Second Timer and Buzzer (mechanical timer units only)
The buzzer provides an audible signal to indicate completion of a timed steaming
cycle. With power applied across terminals 2 and 3 (see Figure 5-20), the 3-second
timer contact closes. This allows power flow through terminals 1 and 2 to the
buzzer. After 3 seconds, the 3-second timer contact opens and silences the buzzer.
The buzzer also sounds at the end of MANUAL steaming when the operator sets
the TIMED/MANUAL switch to TIMED.
Heater Element - Model 24-CEA-10
Two heater assemblies in each generator are located inside the generator near the
bottom. Each assembly comes as a three-coil element. In this text, heater element
refers to the complete heater assembly. Heater coil refers to each of the three coils
in the assembly. For proper operation of the SteamCraft 10, the rating of the heater
element must match the external supply voltage. The heater coils, connected in a
delta configuration, provide 8-kW heating power . Each heater coil supplies one
third of this power (2.67 kW). Table 6-1 lists electrical characteristics of elements
supplied for various voltages.
Dryer Element- Model 24-CEA-10
The 300-W dryer element mounts inside the generator near the top. The dryer
element eliminates any droplet carryover as the steam exits the generator.
Carryover of small water droplets results in improper cooking and soggy food.
Optimum steam convection cooking demands dry steam with no carryover.
Carryover also erodes and enlarges the nozzle holes. When needed, use 300-watt
elements listed in Table 6-2 as replacements.
High Temperature Limit Switch
The high temperature limit switch operates to protect the heater coils from
overheating. If the temperature near the heater element reaches 240°F, the switch
opens. This interrupts power to the heater contactor to prevent operation of the
heater element.
