When water touches the probe flag, the resistance between the probe and
ground drops below the set point, and the solenoid valve shuts
immediately. See Water Level Control Testing section, page 65.
The condenser spray solenoid energizes (valve open) during all cooking
cycles while the compartment door is closed. This maintains a steady flow
of cooling water to the condenser during steamer operation.
The steamer circuits are ready to generate steam when ALL three of the
following conditions are met
• The compartment door is closed.
• Water level is above the low water probe (WATER alarm is not fit).
• One of the cooking cycles (TIMED or MANUAL) is in progress.
For ease of access, the front and tear contactors mount on removable
base plates. Remove the nut (Figure 5-4) from the front end of the plate.
Lift the front edge of the plate and slide it toward the front. The rear base
plate nut may need to be loosened to allow the plate to slide freely.
The front contactor energizes during standby steaming cycles. The
SteamCraft V operates in standby anytime the steamer has been ener-
gized by pressing the POWER switch on the front panel, the door is
closed, and the water level is above the low water probe. Contacts (L2 and
L3 for DELTA connection, L1 and L2 for WYE connection) of the front
contactor close to turn ON the fan motor and the 5.3 kW heater nearest
the left side of the unit. This maintains water temperature at 190 F. During
the steaming cycles, the front contactor remains energized and the tear
contactor cycles as described below. See the schematic and wiring
diagrams (refer to Table 6-1).
For units with 3-wire DELTA connection, contact L1 doses to supply power
to one side of the middle two 2.56 kW heaters.
For units with 4-wire WYE connection, L3 doses to connect neutral to the
two 2.56 kW heaters, the right side 53 kW heater, and the 300 W fan
motor heater.
The rear contactor functions during steaming cycles when the steamer
ready conditions are met
For DELTA connected units, contacts L1 and L2 close to energize the right
side 5.3 kW heater and the 300 W fan heater. Contact L3 doses to
complete the circuit through the two 2.56 kW heaters. Both front and rear
contactors must energize to operate the 2.56 kW heaters.
