This section displays information about how good the line voltage supply
has been for the present day and for the present batch of oil. The control-
ler continually monitors the line voltage supplied to the fryer (when the
fryer is on). If the line voltage drops below [90%] of its nominal value, the
controller signals a "LOW VOLTAGE" alarm. This alarm sounds at the end
of each cook cycle for which low voltage has been detected. While not
cooking, the low voltage alarm can sound as frequently as every 30 mi-
nutes. The D3: Line Voltage Performance Report contains the following
information:
•
If no low voltage warnings have been detected for the present day the
controller shows: "D3: VOLTAGE OK" "D3: TODAY".
•
If one or more low voltage warnings have been detected for the
present day the following sequence example could be displayed: "D3:
YOU HAD 2" "D3: LOW VOLTAGE" "D3: WARNINGS" "D3: TODAY".
Press the down button.
•
"D3: MIN VOLTAGE" "D3: TODAY = 83%". Press the down button.
•
"D3: MAX VOLTAGE" "D3: TODAY = 101%". Press the down button.
•
If one or more low voltage warnings have been detected before today,
the following sequence is displayed: "D3: BEFORE TODAY" "D3: 27
LOW VOLT" "D3: WARNINGS" "D3: ON THIS OIL". Press the down
button.
•
"D3: MIN VOLTAGE" "D3: BEFORE TODAY" "D3: = 85%". Press the
down button.
•
"D3: MAX VOLTAGE" "D3: BEFORE TODAY" "D3: = 105%"

"[ ]" around a value, such as [90%], means this value is programmable
and might change with later software versions.
This section reports the present status of the heating system. The control-
ler examines a history of heat-up data and determines whether or not the
heating system is operating normally. The "heat capacity" is said to be bad
only if the most recent heat-up failed to meet the expected heat-up rate
and three of the last four heat-ups also failed to achieve the expected rate.
That is, a single slow heat-up will not trigger a "slow heat" warning. The
slow heat warning is activated only after repeated low-rate heat-ups is ob-
served. The controller can't assess the integrity of the heating system if
the fryer has been experiencing voltage problems. Low heat rates ob-
served in this situation might be due to voltage problems rather than
