IMPORTANT INFORMATION ABOUT THE
CONTROL PANEL
SQ1
The control panel system maintains heater temperature to between 45 to 55 degrees
Celcius and switches the motor on and off as required. The Heater on the SQ1 is preset
and you cannot change the temperature.
There are 3 LED indicators. The Heater light comes on when you switch on the fountain
and it will stay on until the temperature reaches 55 degrees and it will go off as the control
panel cuts off the heater and it will comes on again when the temperature reaches 45
Degrees. This cycle will continue untill you switch off the switch.
The Motor light will come on when the motor is switched on. Please note the motor will
only turn on once the Indictor stops flashing. The membrane switch panel has a push-
button ON/OFF switch that controls the motor.
SQ2 and SQ3
The control system switches the chocolate heater on and off so as to maintain the
temperature at a pre-set level, and switches the motor on and off as required.
There is a two digit LED display to indicate the temperature in degrees Celcius, and also
two individual LED indicators which light when the heater and motor respectively are on.
A membrane switch panel has a pair of push-button switches for UP ( + ) and DOWN ( - )
to control the temperature, and a third push-button commands the ON/OFF state of the
motor.
1) SETTING THE TEMPERATURE
When either of the ( + )or ( - ) push-buttons is pressed the system enters the temperature
setting mode and the display shows the existing unchanged set point temperature. The
two display decimal points flash on alternately to confirm that the temperature setting
mode is enabled. Further presses of the ( + ) or ( - ) push-buttons cause the temperature
to be increased or decreased respectively by 1°C at a time, but if either push-button is
held for longer than two seconds the temperature is raised or lowered continuously at a
rate of 3°C per second for as long as the push button is held. If the temperature reaches
99°C, further use of the ( + ) push-button cannot alter the temperature further nor if the
temperature reaches 0°C the ( - ) push-button will not have any effect.
If neither push-button is operated for longer than three seconds, the system automatically
comes out of the temperature setting mode and the flashing decimal points turn off. At
the same time the final set temperature value (TSET) is stored .This value will be retrieved
and subsequently used when the fountain is next switched on.
2) TEMPERATURE CONTROL
When the fountain is switched on, the heater is always in the ON state initially, and the
Heater LED is illuminated. The temperature will fluctuate around your set temperature,
thus the hysteresis band is 2°C. If the temperature sensor fails, or is un-plugged from the
control board, the heater and the motor are both switched OFF, and the display shows
‘SF’ (Sensor Fault).
3) MOTOR CONTROL
When the fountain is switched on, the motor is always in the OFF state initially, and the
Motor LED is off. The motor subsequently runs ON when the
( ON )
push-button is pressed,
and the Motor LED is illuminated. Subsequent operation of the
( ON / OFF )
push-button
toggles the motor and indicator between the ON and OFF states.
However, if when the motor is set to be
( ON )
the motor will only start when the actual
temperature gets to within 10°C of the temperature set using the control panel (eg.
Fountain set at 80°C motor will only function when actual temperature reaches 70°C). In
this event, the display shows ‘LT’ (Low temperature) for two seconds before it reverts to
