Initial Power Up
The initial power up sequence is only performed the first time the unit is turned on. The initial power up sequence is
performed regardless of the voltage detected at power up. The following tests are performed at initial power up:
1. POST
2. Detect input voltage and input frequency.
3. Detect single/double oven status.
4. If detecting 60 Hz input, then set to default US units and English language.
5. If detecting 50 Hz input, then set to default metric units and prompt for language selection.
6. Display set Time Of Day (TOD) screen for 5 minutes then go to Idle mode.
Showroom Power Up
The showroom power up sequence is performed when the unit is turned on in showroom mode:
1. Detect input voltage and input frequency.
2. Detect single/double oven status.
3. Display set TOD screen for 5 minutes then go to Idle mode.
Sabbath Power Up
The Sabbath power up sequence is performed when the unit is turned on in Sabbath mode. The display shall remain
blank during the Sabbath power up sequence:
1. POST
2. Detect input voltage and input frequency.
3. Detect single/double oven status.
Normal Power Up
The normal power up sequence is performed at all other power ups:
1. POST
2. Detect input voltage and input frequency.
3. Detect single/double oven status.
4. Display set TOD screen for 5 minutes then go to Idle mode.
Power Down Mode
This mode is activated when the power supply detects a drop on the incoming power. During this time the system
saves the TOD and writes out to flash memory any statistics buffered in RAM. The controls will conserve power to
keep the minimal system alive during this mode. The display and oven elements do not operate during this mode.
The safety systems are not compromised while in this mode. If the incoming power is not restored after the system
completes the shutdown procedure, the controls will enter a reset state. If the incoming power is restored before the
system completes the shutdown procedure, the controls will resume the previous mode.
Idle Mode
This mode is the default mode when another mode is not active. The purpose of idle mode is to display the TOD
clock and wait for input to enter another mode. Oven lights, cooling fan and timers are active during this mode.
