This section shows the current psi of the lid. If OK is on the display, the lid is safe to open. Otherwise, PR; flashes showing lid is under pressure. The bottom display reads Lid Pin;. If OK is on the display, the lid pin is down. Other wise, PR flashes showing the pin is raised (under pressure).

This section shows the current pumping pressure in psi.

Press the illuminated button next to the feature to test. Pri - Primary Contactor. Ht - Heat (regulating) Contactor. Pr - Pressure Solenoid. * - On. - - Off.

Be sure drain pan is in place before testing drain valve. This section tests the drain valve functions. ► - Shows next to the drain valve current state. Par - Partially open. Stp - Forced stop. Opn - Fully open. At - Where the drain valve stopped from 00-20. Max open position may be as high as 25 or 50. Cls - Fully closed.

This section tests the selector valve rotation position. Cst - Coast counts how much the motor coasts after being turned off (11 = typical). Stp - Stop the selector valve rotation. Fwd - Press to rotate the selector valve forward. Rev - Press to rotate the selector valve in reverse. Enc (encoder) - Shows the position count, 0 to 999. When running, top line shows time of each revolution.

This section tests the positioning of each port on the selector valve. P0 - At pot. P1 - At dispose (rear dispose) P2- At FDI (front dispose) Enc - Encoder position. FAIL - Selector valve does not function properly.

Press the illuminated button next to the function to start test * - On - - Off Fltr - Filter pump ATO- JIB pump (optional) Drn C - Drain valve (c - closed, o - open)

This section shows if the unit is equipped with a radio system. To change the option press the plus or minus button to select YES or NO

If the control is equipped with an OPS/QPM ZigBee radio module, and it has been enabled (step T-23 or SP-4), this test mode displays information received from the radio module via the wired connection. If the OPS System is disabled (see previous step), this step simply displays ZigBee IS -OFFT

This test mode is available to display the current lowlevel analog status of any of the analog inputs on the primary Analog to Digital converter chip inside the control.

This test mode has very specialized and very limited use. It displays information about the heating algorithm and its performance, and can be useful when tuning the heating algorithm for a brand new fryer type.

Specifies the pressure reading above which control displays WAIT at the end of the cook cycle - waiting for the pressure to bleed down before beeping and displaying Done

Specifies the pressure reading by which point the lid liner pressure pin monitoring switch must actuate.

Specifies how long to wait at the end of the cook cycle - i.e. when the cook timer has counted down to 0:00 - before generating an E-86B error code if the pressure hasn't bled down to a reasonable level so that the lid can be opened.

Specifies whether or not the auto-cycle the pressure solenoid feature is enabled. If enabled, a short time after every cook cycle in which the pressure solenoid is not used, the control cycles the pressure solenoid on and off. This keeps the solenoid from getting gummed up and sticking. This cycling at the end of a cook cycle occurs only for cook cycles which haven't just used the pressure solenoid. Generally it is used for open fried products being cooked in a pressure fryer.

The control gets a feedback signal from the motorized drain valve when it is at the fully open and fully closed positions. If the control is commanding the drain valve to close, but it doesn’t see the closed feedback signal within a reasonable time, it presumes that maybe a brush has been left in the open drain valve and that is preventing the valve from closing. In response, the control automatically opens the drain valve back up, sounds a sequence of fast beeps, and displays Drain Blocked for a few seconds, giving the user time to remove the brush. After a short delay, the control automatically tries to close the drain valve again.

The auto-topoff (ATO) oil level detection system monitors the temperature difference between the main probe (just above the heating elements) and the level probe (located at the desired oil fill level). In static, noncooking situations, the level probe, high in the pot, is generally cooler than the main probe, even when the pot is properly filled and both probes are immersed in the oil (the oil at the top of the pot radiates a lot of its heat, and conducts heat away, into the air).

In static noncooking situations, the level probe high in the pot is generally cooler than the main probe even when the pot is properly filled and both are immersed in the oil.

When refilling the pot after a filter operation, the control monitors the upper temperature probe (the level probe, at the oil fill line) and looks for a temperature rise there that indicates the oil has refilled high enough to reach or splash on that probe.

How the control monitors the level probe for a temperature rise when refilling the pot is described in the details of step T-34. This T-36 parameter specifies a minimum reasonable filling time for that temperature rise to be trusted.

The default Tech Mode password can be changed by the user. This password is used for entry to Tech Mode and Stats Mode. It is recommended that this password not be changed except under extreme circumstances, as a service technician visiting the store to service the fryer would probably not know the new password and would not be able to access Tech Mode.

Press and hold the button next to hold on the display to initialize the control board.

Manually turn on the protection probe feature. Must upgrade software to v1.60 to use this feature. For software v1.60 and after, the control auto-detects whether the probe is connected when the fryer enters the melt cycle for the first time and sees the probe 50°F hotter than the main temp probe.
