Freezer Pressure Switch.
The freezing time period for the production of cylinder or crushed ice is
controlled by the freezer pressure switch (FPS) located inside the control panel.
This switch was set at the factory to produce ice of recommended thickness. Look at the “Certificate
of Test” which was provided with the machine for a sample set of pressure readings with
corresponding time periods and water temperatures. Also see TABLE 10-6, Operating Vitals for
typical settings. Do not make adjustments until several ice discharging cycles have been made.
FIGURE 9-1
Allen Bradley Pressure Switch
The following procedure is recommended for initially setting an AB pressure switch which has
not
been previously adjusted:
1. Turn the bottom screw (differential) approximately 1/2 turn to the Left (counter clockwise).
The pointer arrow, which is at the top middle of the switch, will be at the “F” setting. See
FIGURE 9-1.
2. Turn the top screw (range adjustment) approximately 4 1/2 turns to the Left (counter
clockwise). The pointer on the range setting will be between 40 psi and 50 psi. See
FIGURE 9-1.
3. After the machine is running, the range adjustment (top screw) will have to be fine tuned to get
the proper ice thickness. (Clockwise = Thinner Ice) (Counter Clockwise = Thicker Ice)
The freezing time can be such that a small percentage of the ice is frozen solid. If so, some ice from
the top and bottom of the freezer should have a small hole in the center to insure that the freezing
time has not been extended to where a loss in capacity would result.
