ADJUSTMENTS AFTER
INSTALLATION
This section describes the adjustments needed after the Adjustable
Pressure Switch has been properly installed.
Pressure settings are internally adjustable using the adjustment
handles.
Never remove the cover in a hazardous environment with the
power on.
ADJUSTMENTS
1.
It is recommended that the unit be in a non-hazardous
location during adjustment.
2.
Disconnect the electrical power. Check for multiple circuits.
3.
Remove the access cover. Lift the insulator flap that contains
the adjustment diagram, exposing the adjustment handles.
4.
To change the setpoint, the adjustment spring handles can be
manipulated by hand or with a small-shafted screw driver or
similar tool inserted into the end of the desired handle. The
handle for decreasing the setpoints is next to the housing wall
adjacent to the pressure port; the other handle, closer to the
center of the housing, increases the setpoints. See Figure 1.
