Board and Computer Replacement

Readdress All Boards

It is necessary to readdress any replaced boards by resetting all power to the entire fryer battery system.

The control power reset switch is a momentary rocker switch located behind the control box above the JIB that resets all power to all the computers and boards in the fryer. Press and hold the switch for at least 10 seconds when resetting the control power to ensure power has sufficiently drained from boards. After releasing the momentary control power reset switch, wait at least 20 seconds until the MIB board has completely reset and all LEDs have stopped blinking before starting a function.

ATO Board, LON Gateway, ATO Pump Relay, and Transformer Replacement

The LON gateway and ATO board are located inside the box behind the JIB. The LON gateway covers the ATO board and must be removed to access it. Both are connected to single phase power from the control box.

1.Disconnect the fryer from the electrical power supply.

2.Locate the ATO box behind the JIB (Jug In Box).

3.Remove the cover to expose the transformers, relay, and LON gateway (if installed; see image below, left).

4.Mark and unplug any wires or harnesses.

5.Once the LON gateway is removed, the ATO board is visible (see image below, right).

6.Replace the defective component and reattach all wires or harnesses.

7.Replace the cover.

8.CYCLE POWER TO ENTIRE FRYER SYSTEM (see section above).

9.Press the TEMP button on one of the M3000 computers to verify software version of the ATO. If the version is not visible, the ATO may not be connected properly.
