Press the Program button to continue onto INP A_VHDSF_M checks.

11. INP A_VHDSF_M

This mode displays the status of components and inputs. If the input signal is detected, an identifying letter is displayed (see below). If the signal is not detected, “_” is displayed. With the COOK/PUMP switch turned to COOK, and all inputs detected, “H_ P_ A_VHDSF_M” shows in the display, for electric fryers; “H_ P_ A_VHDSFP_” for gas fryers. See below for definition of codes.

• A = COOK/PUMP switch turned to COOK

• B = COOK/PUMP switch in PUMP position

• V = Volts - 24 VAC detected

• H = High Limit - If “H” is present, the high limit is good; if “H” is missing, the high limit is tripped (overheated) or faulty

• D = Drain switch - If “D” is present, the drain handle is closed; if “D” is missing, the drain is open or faulty

• S = COOK/PUMP switch “on” interlock circuit: If “S” is present, the COOK/PUMP switch is in the COOK position; if the “S” is missing, the power switch is either off, failed, or wired incorrectly

• F = Fan

• P = PV - Detects 24 V jumper to PV terminal - gas fryers only

• M = MV - Detects 24 V jumper to MV terminal - electric fryers only

Press the Down arrow button to view the specific status of each input.

• 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 V, H, D, S, F, P, and M signals below are wired in series. The first signal missing out of this sequence will generally cause all signals to the right of it to be missing as well.

Press the Program button to continue onto OUTP H* P_ checks.

12. OUTP H* P_

This mode displays the status of components and outputs. If the output signal is detected, an identifying letter is displayed (see below), followed by an “*”. If the output is off, “_” is displayed.

• If heat is on, “H*” displays. If heat is off, “H_” displays. If controls senses a problem with the heat output, “H*” displays, with the “*” flashing.

• If pressure is on, “P*” displays. If pressure is off, “P_” displays. If controls senses a problem with the pressure output, “P*” displays, with the “*” flashing.

Press the Down arrow button to view the “amps” status of each output. “H\/” and “P\/” in the display means the amps are good. A flashing “X” behind the H or P means a problem exists.

Press the Down arrow button to view the no connect/ground (“NC/GD”) status of each output. This monitors a possible problem with the relays on the output PC board.

• “H\/” and “P\/” in the display means everything on the output PC board is good.

• A flashing “X” behind the H or P means a problem exists.

Press the Down arrow button to view the outputs and inputs (see step 10) together.

Press the Program button to continue onto the POT TMP reading.

13. POT TMP

This step shows the present peanut oil temperature. “12. POT TMP (temp.)” displays.

Press the Program button to continue onto the CPU TMP reading.

14. Not Used

This option is reserved for future use.

15. Not Used

16. CPU TMP

This step shows the present PC board temperature.

Press the Program button to continue onto the ANALOG reading.

17. ANALOG <1> 2344

This step displays the present status of any channel of the controller’s a to d converter. This feature may be useful to a technician troubleshooting a problem with the fryer or controller.

The displayed value can be toggled between volts and bits by pressing Product button 1.

• If the displayed value has a decimal point, it is voltage (0 to 5 VDC).

• If no decimal point is shown, the value is a-to-d bits (0 - 4095).

Press the Program button to continue onto AC volts reading.

18. AC VOLTS 98%

This item displays the present status of the line voltage supply to the fryer. The displayed value is averaged over a 10-second period, so brief dips or fluctuations in the voltage might not show up in this display. The voltage is normally displayed as a “percent of nominal” value, where 100% would indicate that voltage is right on the nominal value (i.e. 208 volts for a 208v fryer).

The display can be toggled to an actual Voltage value by pressing Product button 6.

Press the Program button to continue onto AMPS reading.

19. AMPS 33 33 33

For electric fryers, the present readings from the fryer’s amps sensors which monitor the electrical current supplied to the heaters display. (These sensors are not present on gas fryers.) On pressure fryers, these values indicate the current through each supply leg to the heaters. These values do not correspond directly to the current through an individual heater coil. The amps values should normally cycle on and off with the heat light, and all three values should be about the same.

22. ACTIVITY LOG XXXXXX

23. Not Used

This option is reserved for future use.

24. VER & SOURCE

• VER = Version number of the prodcut settings

• SOURCE = Displays where the prodcut sttings came from

25. SINCE

Selecting this option gives the date and time of the last time the fryer was switched to an open/pressure fryer.

26. RADIO INFO

The information displayed under this options start with the word COMM followed by the stat of the radio. The radio can have the following communication messages:

• COM XYZ (XYZ represents one of the following states: idling, connecting, negotiating, waiting for, waiting for radio, connected, ending, and disconnected)

  • IDLING = This state indicates the fryer software is initializing its software stack and delaying before contacting the radio. The fryer adds in a short time delay to allow the radio module time to initialize itself before communication is attempted.

  • CONNECTING = This state indicates the fryer software is starting to communicate with the radio module. This state checks that there is a radio module attached and tells the module a fryer control is attached in order to begin full communications.

  • NEGOTIATING = This state indicates the fryer software has successfully communicated to a radio module and next begins determining security properties of the communications link. This includes first authenticating to each other to help prevent unauthorized modules from being attached. It also determines method of encryption of subsequent data, if any.

  • WAITING FOR = This state indicates the fryer software is doing very early initialization of the basic communications stack. You should never see this state because this is normally done very early on in the boot process.

  • WAITING FOR RADIO = This state indicates the fryer software has opened a successful communications connection to the radio module, but the radio software needs time to fully complete the connection. During this time, the radio module is attempting to establish a connection to the Internet. It also has built-in time delays to allow the fryer to boot and initialize. Depending on the sequence of events, this state may be very short or may be up to several minutes long.

  • CONNECTED = This state indicates the fryer and radio module are successfully communicating to each other. This is the desired state for actively being able to send and receive data during normal operations.

  • ENDING = This state indicates the fryer software or radio module has asked to terminate the data communications link. This usually occurs if the radio module has received an update for itself and needs to reboot to complete the update.

  • DISCONNECTED = This state indicates the fryer and radio module are not communicating anymore. This state is very short, as the fryer will almost immediately move back to Idling before attempting to reestablish communications.

• INTERNET STATUS = Will display a brief diagnostic of the state of the connection of the radio module to the Internet.

• WAN = This screen shows the radio’s IP address as seen by the world as assigned by DHCP from the local access point or wireless router. It may be a routable or non-routable address, but is used for communications between the radio module and the outside world (e.g. the Internet). This address is only updated when the fryer and radio are successfully communicating. If communications is interrupted, the screen will continue to show the last known IP address of the radio. This can help with troubleshooting to see the last known address, but must be used with caution because the radio could acquire a new address (via DHCP) while communications is down between it and the fryer.

• LAN = This screen shows the radio’s IP address as seen by the fryer. It is a non-routable, internal-only address used for communications between itself and the fryer controller. The last digit of the address also indicates which port the fryer controller is connected. For example, if the LAN address is shown as 192.168.10.12, then this fryer controller is connected to Port 2 on the radio module. This address is only updated when the fryer and radio are successfully communicating. If communications is interrupted, the screen will continue to show the last known internal IP address of the radio. This can help with troubleshooting to see the last known address.

• LOC = This screen shows the fryer’s local IP address as seen by the radio module. It is “other end” of the internal network for communications between the radio and fryer. The last digit of the address also indicates which port the fryer controller is connected. For example, if the LOC address is shown as 192.168.10.1, then this fryer controller is connected to Port 1 on the radio module. This address is generally only updated when the fryer and radio are successfully communicating. If communications is interrupted, the screen may continue to show the last known local IP address of the fryer. This can help with troubleshooting to see the last known address.

• AP = This screen shows the version number of the main application software running on the fryer module. This software is primarily responsible for managing the communications between the fryer and the Internet. This value is only updated when the fryer and radio are successfully communicating. If communications are interrupted, the screen will continue to show the last known radio application version number.

• RF = This screen shows a single version number for the radio module’s primary system package, which includes OS, boot loader, and other device driver software and firmware. This value is only updated when the fryer and radio are successfully communicating. If communications is interrupted, the screen will continue to show the last known radio firmware version number.

• IM = This screen shows the version number for the proprietary protocol used to send data between the radio and fryer as reported by the radio module. (In the future, this will also show the fryer’s protocol version number.) This value is only updated when the fryer and radio are successfully communicating. If communications is interrupted, the screen will continue to show the last known radio communications protocol version number.

• REBOOT RADIO = This screen allows the operator to manually cause a graceful reboot the radio by sending it a special command. While this should never need to be done, the option is available because the radio module is otherwise always powered whenever the fryer itself is powered (or, on a CFE427, whenever the right vat is powered). This command can only be sent while there is active communications between the radio module and fryer controller. There is currently no feedback built into this screen to indicate whether the command was successfully received or the state of the rebooting process. This is an enhancement for the future. In the meantime, use the green LED on the back of the module to determine rudimentary connection status.
