  • Page 13: User Information

    Follett recommends sanitizing the pressurized water lines prior to cleaning the ice machine/dispenser. Follett offers two kits: order P/N 01089572 when a Follett filter system with a pre-filter bowl is present, or P/N 01089580 when a Follett filter system is not present. Follow the instructions provided with the respective kits to sanitize the pressurized water lines immediately before cleaning the ice machine/dispenser.

  • Page 17: Service

    Service Ice machine Operation (all models) Follett’s ice machine consists of four distinct functional systems: § Harvesting system § Water system § Electrical control system § Refrigeration system These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these systems will result in improper operation of the entire ice production cycle.

  • Page 18: Water System

    Water system The water level in the evaporator is controlled by a fill solenoid (Fig 13) and level detecting sensors. Water sensing rods (Fig. 14) extend down into the reservoir at the end of the evaporator assembly. The system works via electrical conductivity as follows: One of the longest probes is a common.

  • Page 20: Ice Machine Operational And Diagnostic Sequences

    Ice machine operational and diagnostic sequences The wiring diagrams that follow illustrate the circuitry of Follett ice machines used with 25/50 series ice dispensers. Both normal operation (stages 1—8) and non-normal diagnostic sequences showing torque-out for use in troubleshooting are shown.
  • Page 21 Normal operation – Stage 2 When continuity is seen between B and C, the water valve de-energizes, the AUGER output (P4) comes on along with the MAKING ICE LED. The auger gearmotor’s start windings are energized through a current style start relay that is pulled in by the initial high current draw of the gearmotor.
  • Page 22 Normal operation – Stage 3 After the initial high current draw drops off, the gearmotor start relay contacts open, dropping out the start winding. The condenser fan output (P3) comes on 0.5 seconds later. Optional in Certain Compressor Models WHITE High Pressure Compressor...
  • Page 23 Normal operation – Stage 4 One second (1 s) after the fan comes on, the COMPRESSOR output comes on. The compressor circuit uses both run and start capacitors along with a potential start relay. The start winding is energized through the run capacitor, and through the start capacitor and the normally closed contacts of the start relay.
  • Page 24 Normal operation – Stage 5 As the compressor comes up to normal running speed, its start winding generates a voltage potential across the relay’s coil. This energizes the coil to open the contact and drop out the start capacitor. The ice machine is now in a normal ice making mode. The ice machine will produce ice until the bin level control in the ice dispenser is satisfied.
  • Page 25 Normal operation – Stage 6 Once the bin thermostat control opens, the LOW BIN LED goes out. After a 10 second delay the compressor and gearmotor outputs turn off, the MAKING ICE LED goes out and the TIME DELAY LED comes on. Optional in Certain Compressor Models WHITE...
  • Page 26 Normal operation – Stage 7 The fan motor continues for 10 minutes before shutting off. The TIME DELAY LED remains on for 20 minutes. The ice machine will not start while the TIME DELAY LED is on. To restart the ice machine for troubleshooting purposes, depress the reset button to clear the control board.
  • Page 27 Normal operation – Stage 8 When the dwell time of 20 minutes has expired, the TIME DELAY LED goes off. If 5 seconds of ice has been dispensed and the SLEEP CYCLE LED (Symphony Plus only) is off, the ice machine will go through the normal start-up sequence when the bin level control signals the control board for ice.
  • Page 28 Self-flushing (when enabled) At the completion of the 20 minute time delay, the machine checks for a cumulative one hour of ice making time since the last off-cycle flush. If the cumulative ice making time exceeds one hour, the machine will energize the drain valve P19 for 60 seconds to drain the evaporator.

  • Page 29: Diagnostic Stages

    Diagnostic stages High gearmotor amps – Stage 1 The HI AMPS error and TIME DELAY LEDs are on indicating that the control board has sensed an over-torque condition at the P4 terminal (more than 3 amps from the gearmotor) or no current draw (0A) and shut the ice machine down (strike one).
  • Page 30 High gearmotor amps – Stage 2 If the restart is successful the board will continue to monitor the current draw on P4 for 60 minutes looking for a second high amps (above 3A) occurrence. If the ice machine runs without problems for 60 minutes and no additional torque errors occur, the ice machine will continue normal operation.
  • Page 31 High gearmotor amps – Stage 3 If a second occurrence happens during the 60 minute monitoring period, the HI AMPS LED will come on again and shut the machine down (strike two). The HI AMPS LED (without the TIME DELAY LED) will indicate to the technician that two consecutive over-torque situations have occurred.
  • Page 32 Loss of water During operation, the water level cycles between the normal low (D) and normal high (C) water probes - the fill valve (P21) cycling on and off. If continuity is not detected between the common probe (B) and normal low (D) within 10 seconds, the LOW WATER and TIME DELAY LEDs will come on and the machine will shut down for the one hour time delay period.
  • Page 33 High refrigerant pressure Should the refrigeration discharge pressure rise above 425 psi, the high pressure switch contacts will open. The board sees the open circuit and the HIGH PRESSURE and TIME DELAY LEDs will come on, the machine shuts down. After the one hour time delay, the machine will attempt to restart. If the pressure has fallen below the reset point of 295 psi and the board detects the contacts closed, the machine will resume normal operation.
  • Page 34 Service If continuity is seen between the two drain clog sensor probes, the SERVICE LED will come on and the machine will shut down. The machine will not restart unless the manual reset button is depressed while power is on. Optional in Certain Compressor Models WHITE...
