  • Page 36: Phase Check

    4-14 Phase Check Do not attempt to start the machine without priming the water pump and insuring proper rotation of both the cutter motor and pump motor. Cutter and pump motor rotation are synchronized at the factory but must be checked at installation. For ice production, the cutter disc, as viewed at the ice discharge opening, should turn from left to right.

  • Page 37: Current Imbalance

    4-15 Current Imbalance Voltage imbalance causes a current imbalance, but a current imbalance does not necessarily mean that a voltage imbalance exists. A loose terminal connection or a buildup of dirt or carbon on one set of contacts would cause a higher resistance on that leg than on the other two legs. Current follows the path of least resistance; therefore, if Terminal L1 is loose or dirty, L2 and/or L3 will have higher current.

    Excessive condensing pressure in water-cooled condensers may also be due to: • Accumulation of scale in the cooling coil • Insufficient cooling water • Excessive water temperature Valve Stations The P34HL is supplied with valve stations that provide all valve functions in a single unit rather than a train of independent valves.

  • Page 98: Capacitive Level Control

    Capacitive Level Control The liquid level in the freezer is controlled by a Hansen Vari-Level® system that consists of a capacitive probe that sends a digital signal to a control unit. The control unit is the operator interface that contains the digital readout of the liquid level in the freezer along with knobs and dials for adjusting the liquid level.

  • Page 99: Set Point And Operation

    Prior to connecting electrical power, check the voltage on the control unit nameplate and the power supply at the wire leads to ensure that they are identical. The supply voltage must not be more than 10% above nor 15% below the listed voltage. Connect the power supply leads to the quick disconnect plug (Terminals 1 and 2) and secure into the appropriate marked socket.

  • Page 100: High Level Adjustment

    High Level Adjustment This set point signals that the liquid level is becoming too high in the freezer.
