1.12 Basket Lift Service Procedures

™
FQG30 series gas fryers may be equipped with automatic basket lifts. Basket lifts always come in pairs,
although each operates independently.
A modular basket lift (illustrated on the following page) is a self-contained sub-assembly consisting of a pair
of toothed rods, which support removable basket lift arms, a pair of reversible-drive gear motors, and four
microswitches. The gear motors engage the teeth of the rods, moving them up or down depending upon the
motors' direction of rotation. The microswitches at the upper and lower limits of movement stop the motors
when the basket is in the full up or full down position.
Timing circuitry in the controller initiates and stops basket lift operation depending upon the variables
programmed by the operator. When the product button is pressed, the timing circuitry activates a coil in the
basket lift relay to supply power to the lower microswitch. The microswitches stop the motor at the lift's upper
and lower travel limits and reverse the direction of current flow thus reversing the motor direction.
When the product button is pushed on the controller, current flows through a coil in the basket lift relay,
causing the lower circuit to be activated. The basket lift lowers, closing the normally open upper-micro-switch.
When the downward-moving rod opens the lower normally closed microswitch, the power to the motor ceases
to flow. When the controller times out, the current to the relay coil is cut, allowing the upper circuit to be
activated. The basket lift rises and re-closes the lower microswitch. When the basket lift rod clears the upper
microswitch, the microswitch reopens, power to the circuit is cut, and the motor stops. Pushing the product
button restarts the cycle.
Problems with the basket lift can be grouped into three categories:
Binding/jamming problems
●
Motor and gear problems
●
Electronic problems
●
100-120V C onfiguration
Binding and Jamming Issues
Noisy, jerky or erratic movement of the lifts is usually due to lack of lubrication of the rods and their bushings.
