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 suffi ciently 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.
Disconnect the fryer from the electrical power supply.
Locate the ATO box behind the JIB (Jug In Box).
Remove the cover to expose the transformers, relay, and LON gateway (if installed; see image
below, left).
Mark and unplug any wires or harnesses.
Once the LON gateway is removed, the ATO board is visible (see image below, right).
Replace the defective component and reattach all wires or harnesses.
Replace the cover.
CYCLE POWER TO ENTIRE FRYER SYSTEM (see section above).
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. 1.
