Sequence of Operation
The following “action-reaction” outline is provided
to help you understand how the braising pan
actually functions.
When you start up the pan by turning the
thermostat from “OFF” to a desired temperature,
the thermostat switch closes. This causes the
contactors to close, and allows power to flow to
the heating elements and the indicator light.
When the pan temperature reaches the value
set on the thermostat dial, the thermostat switch
opens and causes the contactors to open. This
stops the flow of power to the heating elements
and the indicator light.
As soon as the thermostat senses that the pan is
cooling below the set temperature, the
thermostat closes, the contactors close, and the
heaters and indicator light come on again.
This on and off cycle continues, maintaining the
pan at the set temperature. This is why the
indicator light on and off cycling is seen during
normal operation.
If the pan temperature exceeds 425
o
F for any
reason, a high-limit thermostat shuts off the
power until the pan cools. At that point, the
thermostat automatically resets to permit normal
operation to start again.
Turning the thermostat to “OFF” shuts down all
control and heating circuits.
The thermostat controls heating by alternating
between feeding full power and completely
cutting power off. The pan heats as fast as it
can until it reaches the set temperature, no
matter what that temperature is. Turning the
thermostat to a higher setting will cause heating
to continue longer, until the pan reaches a higher
temperature, but it cannot make the pan heat
any faster.
The power tilt switch controls a reversible motor
that drives a ball screw mechanism. When the
switch is held in the lowered position, the
mechanism raises the pan body. The body rests
on a trunnion near the front corners, so it tilts
forward until the switch is released or the body
reaches its vertical limit.
If the tilting motor gets too hot during operation,
an overheat protection switch will open and stop
the motor. When the motor has cooled
sufficiently, the switch will automatically reset
and permit tilting to begin again.
