election

For North America oven models, the oven will detect 208 or 240 incoming voltage.

The initial voltage selection is typically completed before the oven is used by the customer. However, if incoming voltage for the store is different than the preset voltage, the operator will be required to select either 208 or 240 after pr

essing the O

n/Off key to turn on the oven. The correct voltage will be enlarged on the screen, identifying which option to select (see Figure 3 below).

For information on accessing and removing parts, see the Appendix.

Blower Motor (Bottom)

The bottom blower motor is a brushless AC-switch reluctance type and spins clockwise. Its top speed is 7100 RPM at 1 HP, and it is controlled by a pr

oprietary controller.

The bottom blo

wer motor can be tested in Test

Mode (see page 13).

Blo

wer Motor (Top)

The top blower motor is a brushless AC-switch r

eluctance type and spins counterclockwise. Its top speed is 7100 RPM at 1 HP, and it is controlled by a proprietary controller.

The top blower motor can be tested in Test Mode (see page 13).

Blo

wer Motor Speed Controller (BMSC)

The motor contr

oller is proprietary and will only

operate the motors described abo

ve. It is controlled via 0-10 VDC speed command from the I/O control board and can be tested in Test Mode by testing the blo

er motors (see page 13). For

additional troubleshooting, see page 33.

Heater Elements

The main conv

ection heaters are sheathed-style

and rated at 3000 watts at 208

C, with a resistance of 14.4 Ohms. The convection heaters ar

e controlled by the K4/K5 solid state relay, and

can be tested in Test Mode (see page 13).

Jetpla

te (Bottom)

The bottom jetplate channels air generated from the bottom blo

wer motor into the cook cavity.

Jetplate (Top)

The top jetplate channels air generated fr

om the top blower motor into the cook cavity. Before the air passes through the jetplate nozzles, it is mixed by a stirrer.

CAUTION: The top jetplate is ceramic. Be car

conducts to pr

event the filament voltage from becoming positive, thus as the high-voltage winding of the transformer goes to a peak of 2400 v

high-voltage capacitor is charged to 2400 volts.

When the high-v

y - K6 Voltage

The K6 relay is a 240 VAC, 30 amp, three-pole, double-throw, 24 VDC relay coil. Operational in N

th America only, it switches between 208 and

240

VAC on the HV transformer and filament

transformer taps (depending on incoming v

oltage). Through the voltage sensor, the oven defaults to the 240V position and switches to 208 if less than 222 v

olts is detected. 230V/400V international ovens and all Japan models utilize the N.C. contacts of the relay to power the microwave transformers.

Relay - K7 Monitor

The K7 relay is a 240 VAC, 30 amp, double-pole, double-throw, 24 VDC relay coil. It shorts L1 and L2 if the monitor switch opens befor

e the primar

or secondary switches.

elay - K8 Anode

The K8 relay is a 240 VAC, 30 amp, double-pole, double-thr

ow, 24 VDC relay coil. It switches power

to the high-v

oltage transformers.

The R

TD measur

es the temperature of the heater element. If the display reads “999°F/C”, the RTD is open, resulting in an F7 fault. See page 37 for troubleshooting.

Testing Procedure:

Disconnect the RTD from the control harness.

2. Place the RTD in ice water for two minutes.

Take a resistance reading of the RTD.

If RTD resistance is not 100

W, the R

TD is

defectiv

e and must be replaced.

TE: Use Figure 35 below to determine resist-

ance readings at temperatures other than freezing.

Smart Card Reader

The smar

load menus and firmwar

e updates from a smart card. An oven’s menu can also be saved to a smart card. For instructions, see page 16.

Solid State Relay - K4/K5 Heater

The solid state relay is a 240 VAC, dual 40-amp relay. K4 switches power to heater one, and K5 switches po

er to heater two.
