3.2 ADJUSTMENT OF DIFFERENTIAL PRESSURE SET POINT
In order to adjust the low limit set point of the differential pressure switch, the case door must
be opened, thereby requiring the breaking of the seal attached to the door by the local
health authority.
The set point can be set in one (1) psi increments from 1 to 15 psid simply be relocating the
jumper (located under the bar graph of red LEDs), into the corresponding socket, as shown
in Figure 10.
Insert the jumper with its arrow oriented upward. Erroneous insertion (pointed sideways), or
no insertion, will inactive the Differential Pressure Switch so that the switch will remain open
and the Booster Pump cannot be turned on.
The set point selected is shown by a single red LED on the lower bargraph. The actual
differential pressure to the nearest whole number is shown on the horizontal bar graph
above the set point LEDs.
When the differential pressure is above the set point, the green LED light (F) is turned on to
indicate the Booster Pump switch is energized. When the differential pressure is below the
set point, the red LED light is turned on to indicate the Booster Pump switch is de-energized.
These LEDs are located between the raw and pasteurized display, as shown in Figure 11.
NOTE: For units with the optional 5-75 psi differential range, each LED equals a 5 psi
increment.
