    ISTORY OF OMPANY Henry Vogt Machine Co. was founded as a small machine shop in Louisville, Kentucky in 1880. In 1938, Vogt built the first Tube-Ice ® machine and revolutionized the ice-making industry. Our first “sized-ice” machine quickly replaced the old can-ice plants, which required much hard labor and large amounts of floor space for freezing, cutting, and crushing ice by hand.

    (i.e., the trucker’s Bill of Lading). Immediately make a separate written request for inspection by the freight line’s agent. Any repair work or alteration to the machine without the permission of the Vogt Ice can void the machine’s warranty. You should also notify your Vogt distributor or the factory.

The PLC controls the sequence of events and monitors the ice machine functions. The operational sequences of the VT-Series ice machine can be described best as a series of six different modes.

  • Page 31: Harvest Mode

    After five seconds, the “D” (thaw gas) solenoid valves open and the chopper motor starts. On split VT40’s & VT60’s, the hot gas loop valve energizes and VT80 & VT100 the suction stop valve energizes when the chopper starts and thaw gas valves open. When the suction pressure reaches the set point on the Harvest Hold (HH) pressure switch (PLC input #2 light will turn “off”), the harvest timer will begin to time.
