Adjusting the Set Points
The Series 919 Controller has two, independently adjustable set points
that can be used throughout its operating range. LEDs indicate when
the set points are active. When the power is turned off, the set points
remain unchanged.
To adjust a set point to open or close the relay contact at a
particular pressure,
1 Depress the set point push-button, SP1 or SP2, on the front panel.
See figure at left.
2 Using a small screwdriver, adjust the corresponding potentiometer
until the display reading coincides with the desired set point pressure.
3 Repeat this process for the other set point if desired.
