Kettle Dump
– The Kettle Signal to Dump (yellow light/buzzer) is factory set. For the
signal to dump to be a little sooner or later, adjust the Kettle Dump potentiometer
(reference image shown). Turn clockwise (CW) to signal sooner, counterclockwise
(CCW) to signal later.
4.
Audible Signal to Dump
- The buzzer has three options; full volume, half volume, or
no sound (yellow light only). Unit is preset at the factory to full volume. Adjustments
are made by jumper positions (reference image shown).
Probe LED Indicator Light – Thermocouple Error Condition
The Dump Light on the Popper will be on steady and the unit will beep (if Audio Signal engaged)
when there is a Probe issue (the kettle will not heat enough to pop corn). Check the control
board, the red Probe LED light ON will indicate one of two thermocouple error conditions.
•
Reversed Probe
– Indicates the thermocouple probe has been connected in reverse. (The
yellow leads must go to the positive terminals.)
If the
kettle heats for a short
time and then stops, and the red Probe LED light is ON,
then one (or both) Thermocouple is wired in reverse. Check TC-A and TC-B; make sure
the yellow leads go to the positive terminals.
•
Open Probe
– Indicates the thermocouple probe is disconnected.
If the kettle
does not heat
and/or the beeper sounds continuously, and the red Probe
LED light is ON, there is an issue with the Thermocouple wiring.
For removable kettles -
make sure the kettle lead-in cord is plugged in
completely and the locking ring is fully screwed onto the kettle receptacle.
For hard wired kettles -
A loose kettle lead-in connection can cause a
thermocouple lead issue. Check the terminal blocks for a loose connection, and
check the kettle wiring for a loose or broken thermocouple.
