Page 26 of 40

ELECTRICAL OPERATION

COMPONENT FUNCTION

1A Delime Timer Board

. . . Tracks the cumulative cooking hours by using a current sensor to monitor

current flow through the cold water condenser solenoid lead, then signal’s

operator to perform delime procedure after the steamer has operated in cook

mode for a preset number of hours.

Buzzer

................. Signals end of cook cycle, must be turned “off” manually.

1CON & 2CON

Heater Contactor

......... Controls power to tank heaters. (electric models only)

1-3HTR Heaters

.......... Heat water in Steam Generator tank. (electric models only)

1K Relay

............... Supplies power to control circuit when steam is being generated and the tank

water level drops below the low level probe.

2K Relay

............... Prevents operation of the cook timer until initial fill and heat is complete.

3K Relay

............... Operates drain motor and resets delime timer board when the power switch is

moved to the delime position.

.................... Provides 12VAC power to the delime board.

.................... Provides 24VAC power to ignition control module and HSI. (gas models only)

Ignition Module

......... Controls and monitors gas heating. Applies power to HSI for burner ignition,

monitors flame presence through FSP, controls 5 second purge time and 8.5

second ignition trial time and powers gas solenoid valve. (gas models only)

1LT Ready Light

......... Indicates steam generator tank is up to temperature and cooking can begin.

2LT Delime Light

........ Indicates preset number of cook time hours have accumulated and the tank

should be delimed.

3LT Cook Light

.......... Indicates cook timer has been set and a cook cycle is in process.

4LT Ignition Light

........ Indicates gas burner is on. (gas models only)

High Level Probe

......... Monitors tank water level and signals the WLC when tank is full.

Low Level Probe

......... Keeps the WLC relay coil HL energized when the water level drops below the

high level probe.

Low Level Cut Off Probe

. . . Monitors tank water level and removes electrical power to the LLCO relay when

the water level drops below the low level cut off probe.

FSP (Flame Sense Probe)

. . Supplies a current signal back to the ignition module indicating the presence of a

flame. (gas models only)

HSI (Hot Surface Igniter)

. . When Ignition module applies power, the element heats up to very high

temperatures causing gas ignition. (gas models only)

1M Drain Motor

.......... Controls the tank drain. (normally open valve, water flows when de-energized)
