Press any of the product buttons numerous times to view each
LED across the control panel.
T-17 - DIGITAL INPUTS - HDF
H = HIGH LIMIT - If “H” is present, the high limit is good.
If “-” shows then the high limit is tripped out (overheated) or
disconnected.
D = DRAIN SWITCH - If “D” is present, the drain handle
(when applicable) is closed. If “-” shows then the drain is open
or the switch is faulty.
F = FAN (PRESSURE SWITCH) - If “F” is present, the
pressure switch is good. If “-” shows in the display, the switch
is faulty.
Press button and an underscore (“_”) indicates the input
is not presently detected. A Checkmark (“ √ ” ) indicates the
signal is detecting a normal input. A blinking (“X”) indicates
the signal is presently detected, but is detected as a half-wave
(partially failed) input.
The H, D, F signals above are wired in series. The first signal
missing out of this sequence l generally causes all signals to the
right of it to be missing as well.
T-18 - AIF INFO (AIF PCB communicating with control PCB?)
An “AIF √ ” means normal communications between the AIF
PCB and the control PCB. “AIF X” means a problem with the
communications between the PCBs.
Press button and “FILR IN” and “USE BY 1(ex)” shows
in the displays. These displays shows which controls are using
the filtering system.
“USE BY 0” = not in use
“USE BY 7” = used by AIF
“USE BY 1 to 5” = used by control PCB
Press button and “CPU POSN” and “1 OF 3(ex)” shows in
the displays. These displays shows which controls are plugged
into which port on the AIF board.
For example, the left control should be plugged into port 1, and
on a 3 control fryer, shows “1 OF 3” on the display.
If the right control is unplugged, then the left control would show
“1 OF 2” instead of “1 OF 3”.
