  • Page 24: Control/Map System Sequence Of Operation

    Henny Penny F5/ LOV 300 Open Fryer Control/MAP System Sequence of Operation During fryer operation, the F5 MAP system is continually sending and receiving status messages for system components via the CAN bus. User initiated commands are received by the F5 touch- screen control and then sent as a CAN message packet to the appropriate device.

  • Page 25: Power Distribution Pcb

    Henny Penny F5/ LOV 300Open Fryer Power Distribution PCB Purpose Line AC voltage is supplied to the F5 fryer from the power cord and then converted to 24 volts DC by four separate power supplies. Four power supplies then independently feed 24 volts DC to the Power Distribution PCB which is used to operate all of the MAP system electronic components.

  • Page 40: Cook Cycle

    Henny Penny F5/ LOV 300 Open Fryer Cook Cycle During a product cook cycle, the F5 control system applies heat in a varying duty cycle depending on the oil temperature readings. Generally, full heat is applied for a period at the beginning of a cook cycle to anticipate the effect of product lowering oil temperature.

  • Page 41: Oil Management System (Oms)

    Henny Penny F5/ LOV 300 Open Fryer Oil Management System (OMS) OMS Purpose Tracking of oil movement along with filter queuing and logic is managed by the OMS PCB. Primar- ily, the OMS is powered by 24 volts DC from the Power Distribution PCB. Additionally, line voltage is supplied to the OMS by two of the 15 A push button circuit breakers.

  • Page 45: Filter System Sequence Of Operation

    Henny Penny F5/ LOV 300 Open Fryer Filter System Sequence of Operation Prompts Filter cycles for each vat are initiated through the F5 control panel using different prompts. For Express Filter cycles, the user may be prompted for a filter cycle automatically by the control, or choose to initiate one on their own.

  • Page 46: Filter Pan Switch

    Henny Penny F5/ LOV 300Open Fryer Filter Pan Switch After the user initiates a filter cycle, the F5 control system first checks to verify the filter pan is in place. Filter pan position is confirmed through a circuit from the OMS PCB through a normally open magnetic proximity switch and back to the OMS PCB.

  • Page 47: Drain

    Henny Penny F5/ LOV 300 Open Fryer Drain During the drain sequence, a 24 volt DC signal is sent from the OMS PCB to the drain valve actu- ator which causes the valve to open. With the drain valve open, cooking oil to be filtered flows by gravity from the vat to the drain trough and then to the filter pan.

  • Page 50: Auto Top-Off System Theory Of Operation

    Henny Penny F5/ LOV 300 Open Fryer Auto Top-Off System Theory of Operation Purpose Maintaining proper oil level in all vats is performed by the Auto Top-Off (ATO) system. With nor- mal use, the oil level in any vat will drop lower due cook and filter cycles. A low oil level will result in reduced oil and product quality, oil life, and ultimately nuisance tripping of the high limit safety system.

  • Page 55: Cart Dispose Theory Of Operation

    Disposal of used cooking oil is necessary whenever a vat is filled with new oil. To properly collect and transport used oil, Henny Penny offers a disposal cart that is inserted under the F5 fryer in place of its filter pan. Timing of disposing used cooking oil is entirely up to the the user with no pre- set schedule programmed into the F5 control system.

    Henny Penny F5/ LOV 300 Open Fryer Cart Dispose Sequence of Operation Prompts Dispose to cart sequences are user initiated through the F5 control panel manually. The F5 con- trol system has no provision for automatic prompting of oil dispose sequences. During the on- screen cart dispose control prompts the user is directed to remove the filter pan and then insert the dispose cart.

  • Page 59: Bulk Oil System Theory Of Operation

    Bulk oil systems provide the F5 fryer with a method for storing disposed and supplying fresh cook- ing oil. Processes and communication between the external (non-Henny Penny) bulk oil system and the F5 fryer are tracked by the OMS PCB. Bulk oil processes are divided into two types, bulk dispose and bulk supply.

  • Page 61: Bulk Oil System Sequence Of Operation

    Henny Penny F5/ LOV 300 Open Fryer Bulk Oil System Sequence of Operation Bulk Oil Dispose Control Configuration Prompts Bulk dispose sequences are user initiated through the F5 control panel manually. The F5 control system has no provision for automatic prompting of oil dispose sequences. During the on-screen bulk dispose control prompts the user is directed to drain used oil to the filter pan.

  • Page 62: Selector Valve

    Henny Penny F5/ LOV 300Open Fryer Normally open magnetic proximity switch Filter pan switch is actuated closed with pan inserted Filter Pan Collecting drained oil to be disposed is handled by the filter pan. As oil flows down through the gravity drain system it is first collected for by the dispose cart before being sent to the bulk dis- pose tank.
  • Page 63 Henny Penny F5/ LOV 300 Open Fryer Purge Clearing of old oil in the vat's plumbing is performed by the purge stage. The drain valve remains open and while the user is purging oil and a line voltage AC single-phase signal is sent from the OMS PCB to the ATO pump.
  • Page 64 Depending on bulk oil system type and fryer configuration, the flexible dispose oil line will be either supplied by Henny Penny or the bulk oil system vendor. The Henny Penny provided bulk oil dispose line has a female quick disconnect coupling end that must be mated properly to the bulk oil plumbing before disposed oil will flow.
