R-210A 4 OPERA TION SEQUENCE 7-1. When the oven door is opened during or after the cycle of a cooking program, the 1st latch switch and 2nd latch switch must open their (COM-NO) contacts first. After that the contacts (COM-NC) of the monitor switch can be closed. 7-2. When the oven door is closed. The contacts (COM- NC) of the monitor switch must b[...]

R-210A 5 FUNCTION OF IMPORT ANT COMPONENTS DOOR OPEN MECHANISM The door can be opened by pushing the open button on the control panel. When the open button is pushed, the switch lever on the latch hook is moved upward, operating the latch head. The latch head is moved upward, and released from the latch hook. Now, the door can be opened. LATCH HOOK[...]

R-210A 6 Note: The ON/OFF time ratio does not exactly corre- spond to the percentage of microwave power, because approx. 2 seconds are needed for heat- ing up the magnetron filament.
