Warranty

Warranty

  • This product is warranted to be free from defects in material and/or workmanship for a period of (2) years from date of original installation, not to exceed 30 months from date of shipment from our factory or 240,000 cycles . Any part or component which proves to be faulty in material and/or workmanship within the warranty period will be replaced or repaired (at the option of Prince Castle, Inc.) without cost to the customer for parts, labor, and travel.

    This warranty is subject to the following exceptions/conditions:

  • Use of non-genuine Prince Castle parts voids this warranty and all work must be performed by an authorized Prince Castle Agent.

  • All labor shall be performed during regular work hours. Overtime premium will not be covered.

  • Equipment damaged in shipment, by fire, flood or an act of God is not covered.


Warranty1

Warranty

!

CAUTION

  • Do NOT use anything abrasive because it will scratch the platens, which could cause bun sticking. Only use URT cleaning sponge and sanitized towel wrapped around the head of the cleaning tool to clean the platens. Do not use abrasive materials such as scrapers, steel wool, etc. to clean the buffered Bun Landing Zone or exterior of the unit, as damage to the surface could occur. Failure to follow the correct cleaning procedure and or damage to the platen due to scratches is not covered under the provisions of the warranty.

  • Do NOT use any unapproved agents or cleaning solutions inside or on the surfaces of the toaster unit.


Warranty cycle count

Warranty Cycle Count

  • All warranty claims for 340-URT MUST include cycle count.

    To retrieve cycle count

  • When the toaster is in toasting mode press and hold the “I” button.

  • While holding the “I” button scroll by pressing the “UP or DOWN” arrow until you find the product you want (i.e. Bun, Bagel, or muffin) and the display shows the cycle count (see photo).

Relay ssd

RELAY SSD

  • When the green Light on the relay is illuminated, the voltage across the AC terminals (1/L1 & 2/T1) should be low. Less than one Volt AC.

  • When the green light is off, voltage across the AC terminals should equal supply voltage (i.e. 208V or 240V AC).


Mechanical relay

MECHANICAL RELAY

  • Mechanical relay “K2” (Ice Cube Relay) changes loads when the solenoids are activating. Check at Terminal A&B or at PCB at “J24”. Should equal 0 VDC when it is off and 24 VDC when it is on.

  • Also the light on PCB at location “D16” will light when relay is on.

  • This relay has a 24V DC coil.

    Removing relay “K2”

    ● Remove front screw.

    ● Loosen rear screw, DO NOT remove.

    ● Relay should slide out.


Mechanical relay1

MECHANICAL RELAY

  • Mechanical relay “K1” applies power to the unit after the power switch is turned on. This relay supplies power to the toaster.

  • At tabs 1&0 check for voltage. When the power switch is off it should equal 0 volts AC and when the power switch is on it should equal power source (i.e. 208V AC or 240V AC)


Main pcb

MAIN PCB

  • Verify power going through the Main PCB by checking at locations “P1” & “P4” which are located behind the transformer.

  • Voltage should equal power source (i.e. 208V or 240V ).

  • 5/16” Nut is used to hold the PCB in location.


Main pcb1

Main PCB

  • To verify power is going to the main PCB check location “J21”.

  • At “Blk & Org” wires should equal 24V DC.

  • At “Blk & No Wire” should equal 5V DC.


Main pcb2

Main PCB

  • To verify power is going through the main PCB check at “D5” and “D20”.

  • At “D5” (24V DC) green light should be on.

  • At “D20” (5V DC) green light should be on.

Compression Plates not moving

Verify compression plates are not damaged/bent

Comp. plates are bent, bend back to correct position

Comp. plates are not bent

Check motor/encoder LED at D1. LED should be orange: 24 VDC & 5 VDC

LED is green: 5VDC, replace motor. 340-682S

LED is red: 24VDC, replace motor. 340-682S

Motor is grinding or slow reaction time, replace motor. 340-682S


Motor gear box motor board

Motor/Gear Box & Motor Board

  • The motor opens and closes the Compression plates.

  • Check at connector “J1” “BLK & ORG” wires and should equal 24V DC.

  • Check at Connector “J2” “Violet & Gray” wires (top 2) should equal 5V DC.

  • At “D1” Power Light when it is Green that means 5V DC Red means 24V DC, and orange means both 5V & 24V being applied.

  • If orange light is on and the compression plates are not moving problem can be motor/board.


Solenoids

Solenoids

  • Solenoids control the gates that release the product from the toaster.

  • Check Voltage on Main PCB at Location “J22” for the main side. “Red & Blue” should equal source voltage (i.e. 208V or 240V AC). “Blu & Org” should measure < 1V AC.

  • Check Voltage on Main PCB at “J23” for solenoids on opposite side. “Blk & Blu” should measure < 1V AC and “Blu & Brwn” should equal source Voltage (i.e. 208V or 240V AC).

  • 11/32” Nut driver
