Electronic Issues
Within this category are problems associated with the relays, microswitches, capacitors, resistors,
interface board, wiring, and controls. The most common problem in this category is a lift that
continuously travels up and down. This is usually caused by a microswitch that is out of adjustment.
Troubleshooting the electronics of a modular basket lift is simply a process of verifying current flow
through the individual components up to and including the motor. Using a multimeter set to the 250
VAC range, check the connections on both sides of the component for the presence of the applied line
voltage. The schematic below and the wiring diagram on page 2-8 and 2-9 can identify the
components and wiring connection points.
1.11 ATO (Automatic Top-off) Service Procedures
The automatic top-off system is activated when the oil level falls below a sensor in the rear of the
frypot. The signal is sent to the ATO board to engage the return actuator to the frypot and turn on the
ATO pump. The pump draws oil from the JIB (Jug In Box) through the rear return manifold into the
rear of the frypot. Once the oil level has satisfied the sensor, the pump turns off and the actuator
closes.
The ATO board is located inside the box, behind the JIB (see Figure 1).
The power for the ATO board is supplied from the right hand
component box. The power passes through the transformer inside the
ATO box to the board.
