6.2.7 HIGH-LIMIT TEST MODE
The high-limit test mode is used to test the high limit circuit. The high-limit test will destroy the oil.
It should only be performed with old oil. Shut the fryer off and call for service immediately if the
temperature reaches 460°F (238°C) without the high-limit tripping and the computer displays high
LIMIT FAILURE alternating with DISCONNECT POWER with an alert tone during testing.
The test is cancelled at any time by turning the fryer off. When the fryer is turned back on, it returns
to the operating mode and displays the product.
1. Press and hold the check () button until MAIN MENU is displayed followed by PRODUCT
SETUP.
EXPLANATION
Oil may be present in the filter pan.
Vat did not empty during filtration
Oil level sensor failed.
Recovery time exceeded maximum time limit. Recovery
time should not exceed 2:25 for gas.
Oil temperature has dropped 30°F (17°C) lower than
setpoint in idle mode or 45°F (25°C) in cook mode. (This
message may appear if a product is dropped and the start
cook button is not pressed immediately or if too large of
cook loads are dropped.)
Oil temperature has risen 40°F (22.2°C) higher than the
setpoint. If temperature continues to rise, the high limit will shut
the burner off when temperature reaches 425°F (218°C) Non-
CE or 395°F (202°C) CE.
Oil temperature is too high for a valid OQS reading. Filter at a
temperature between 300ºF (149ºC) and 375ºF (191ºC).
Oil temperature is too low for a valid OQS reading. Filter at a
temperature between 300ºF (149ºC) and 375ºF (191ºC).
The TPM is too low for a valid OQS reading. The incorrect oil
type may be selected in the setup menu. The sensor may not
be calibrated for the oil type. See oil type chart. If issue
continues contact a FAS.
The TPM reading is too high for a valid OQS reading. Dispose
the oil.
The OQS has an internal error. If issue continues contact a
FAS.
The OQS is detecting air in the oil. Check the O-rings and
check/tighten prescreen filter to ensure no air is entering the
OQS sensor. If issue continues contact a FAS.
The OQS sensor has a communication error. Check
connections to the OQS sensor. Power cycle the entire fryer
battery. If issue continues contact a FAS.
