POWER SUPPLY
1. An independent 110 VAC supply line is provided to
the ClockBox.
a. This supply line provides power to the ClockBox,
which is independent from the supply line to the
hood.
2. The ClockBox provides 110 VAC to the Power
Disconnect Assembly
3. The ClockBox provides control signal voltage (5VDC)
and logic control to the Touchscreen [HMI]
4. The Power Disconnect Assembly supplies the input
line to the stove/range as follows:
a. If an Electric Disconnect
- Controls the 110 VAC contactor coil allowing the
220 VAC supply line to the stove/range via the
NEMA 14-50 receptacle.
b. If a Gas Disconnect
- Open the solenoid valve allowing gas to flow to
the input line of the stove/range
c. If Dual Disconnect
- Both conditions 6.a.i and 6.b.i will apply
d. The above reference will be maintained for as long
as there is time left at the ClockBox, it will open
the contact in the timer, stopping the supply line
to the Power Disconnect, which in turn, will shut
off the stove.
NOTE
Some electric stoves/ranges have a warning light
to alert the user that the burners/coils are hot.
These warning lights will be off since the supply line
powering the stove/range is not present.
