Light (2LT), Low Water ...Red (RD) colored light. On when water level in the reservoir jacket drops below water
level (LLCO) probe.
Light (3LT), Heat ..... Amber (AM) colored light. On when temperature controller is calling for heat.
Ignition Fail (4LT) .... Amber (RD) colored light. On when burner does not light.
COMPONENT FUNCTION (POWER TILTING OPTION)
DC Tilt Motor
Controller ............
Controls DC tilt motor operation to tilt the kettle and provides motor acceleration control
each time the controller is powered. The controller outputs approximately 90VDC to
power the motor.
DC Tilt Motor ......... Operates gear reducer to tilt the kettle. When the correct voltage polarity is applied
through K1 contacts, motor rotates CW to raise the kettle. When reverse voltage polarity
is applied through K2 contacts, motor rotates CCW to tilt the kettle. Rotation direction as
viewed from shaft end.
Transformer (2T) ..... Steps down supply voltage to 24VAC (power tilt circuit voltage).
Tilt Motor Switch
(Momentary On/Off/
On) ...................
Energizes K1 relay coil thru K3 raise-enable contacts (N.O.) to raise the kettle. Energizes
K2 relay coil thru down limit switch contacts (N.C.) to tilt the kettle. The switch positions
are: Center neutral (starting) position off; Momentary on - tilt kettle; Momentary on - raise
kettle.
Down Limit Switch ... N.C. contacts function as down limit switch to remove power from K2 relay coil when
kettle is fully tilted (travel stops).
K1 "Up" Relay (3PDT) ... Supplies power to motorized tilt circuit to raise the kettle when 24VAC coil is energized.
K2 "Down" Relay
(3PDT) ...............
Supplies power to motorized tilt circuit to tilt the kettle when 24VAC coil is energized by
the tilt control switch. The voltage polarity to the DC motor is reversed through K2 contacts
to turn motor CW and tilt the kettle.
