Menu Step
For example, on a Gas 4 Head fryer the #1 button toggles the Fan output
on and off, while on an Electric 4 Head fryer, the #1 button toggles the
Heat on and off.
Under manual control, the Heat output will shut off automatically if no
buttons are pressed for 30 seconds.

T-13A Outputs View/set the status of the Pump and Air Valve outputs. If an output is cur-
rently on, a "star" follows the ID letter. If an output is currently off, a line
follows the letter.
PMP = PUMP OUTPUT
AIR = AIR VALVE OUTPUT
The outputs may be manually controlled using the lighted number but-
tons. The #1 button toggles the Pump output on and off, and the #2 but-
ton toggles the Air Valve output on and off.
T-14 Amps If the Amp Sensor Detect Jumper in the amp sensors assembly is not de-
Calibrate tected, the controller shows "XX XX XX " / " -NOT- DETECTED" and all
Amp Sensor warnings and errors are disabled.

The amp sensors monitor the current (amperes) in the heating elements.
Depending on the fryer wiring, each amps reading corresponds to either
the current in one leg of the supply lines, or to the current to one heating
element coil.
Consequently, the amps readings here don't necessarily match the amps
readings of an individual heater, since each leg on the line cord normally
drives two elements (120° out of phase).
Press the DOWN button to view the present Nominal, Low Limit, and
High Limit settings for amps. (These values are programmed in Special
Program mode.)
This step allows manual control of the heat output by pressing the #1 but-
ton. The heat is turned on unconditionally, so make sure there is oil in
the vat (frypot) and take care to not overheat it.
Press the #0 button to view the un-calibrated readings.
C C a a l l i i b b r r a a t t i i o o n n :
Press the TIMER button to perform the calibration sequence, which al-
lows each of the three readings to be adjusted to match reference amp
readings. This calibration requires a meter with an amp clamp to take
readings at each of the three amp sensors in the fryer.
During the calibration sequence, one of the readings is blinking. Use the
UP and DOWN buttons to adjust that reading as necessary. Press the
PROG button to advance to the next reading.
The displayed values, left to right, match the amp sensor order black,
red, and orange. For each amp sensor, the displayed value should be
adjusted to match a reading taken with an amp clamp on the same wire
the amp sensor is on.
