SEQUENCE OF OPERATIONS
When using these instructions refer to the SEL-TI wiring
schematic.
1. Supply Voltage is sent to the primary of the 120
VAC transformer.
2. Supply voltage is sent to the normally open con-
tacts of the Heat Contactors, C 1 and C2.
3. 120 VAC is sent from the secondary of the 120VAC
transformer through the 3 amp fuse to
■ The primary of the 24 VAC transformer
❏ 24 VAC is sent from the secondary of the
24VAC transformer through the 1.25 amp fuse
to the on/off switch.
■ Contacts of the R1 Heat Relay
4. 120 VAC is sent from the secondary of the 120 VAC
transformer to the optional Power Tilt Circuit (See
step 9).
5. With the On/Off switch in the On position.
■ 24 VAC is sent through the normally closed high
limit switch to the mercury switch..
■ If the skillet is in the down position then 24 VAC
is sent through mercury switch to pin 9 on the ther-
mostat.
6. If the steamer is calling for heat the 24 VAC is sent
from pin number 10 to RI Heat Relay.
■ The normally open contacts of the Heat relay
close sending 120 VAC to the Heat contactor coils
C 1 and C2.
7. The Contactor close and supply Voltage is sent to
the elements.
■ The elements heat until the thermostat is satis-
fied.
8. When thermostat is satisfied, 24 VAC is removed
from pin 10 on the thermostat and the heat circuit
is de-energized.
9. If the skillet has the optional Power Tilt option and
is in the down position, 120 VAC is sent from the
secondary of the 120 VAC transformer through the
circuit breaker and the up limit switch to the tilt
switch.
10. With the tilt switch in switch in the Up position
■ 120 VAC is sent to the Bridge Rectifier
❏ 115 VDC is sent from the rectifier through
the 30-ohm resistor to the normally open
RY10 and RYI I relay contacts.
■ 120 VAC is sent to the RY10 relay coil.
■ The normally open RY10 contact close and 90
VDC is sent to the DC motor
■ The DC motor is energized and the skillet tilts
until the switch is released or the up limit switch
opens.
11. With the Tilt switch in the Down position
■ 120 VAC is sent to the Bridge Rectifier
❏ 115 DC is sent from the rectifier through the
30-ohm resistor to the normally open RY 10
and RY 11 relay contacts.
■ 120 VAC is sent to the RY11 relay coil.
■ The normally open RY 11 contact close and the
polarity of the 90 VDC is reversed.
■ The DC motor is energized and the skillet lowers
until the switch is released or
POWER TILT MANUAL OVER-
RIDE
In case of power failure or malfunction the skillet pan
can be tilted manually following these instructions.
1. Fit a 10 MM 6 POINT SOCKET over the MANUAL
TILT SHAFT as shown above.
2. Turn socket wrench clockwise to empty contents.
