Use ground screw to ground enclosure.
SWITCH SETTING
The switches are normally factory set to save time at customer
end. However, they are field adjustable.
CAUTION: Supply voltage should not exceed switch rating. For
higher voltages, the use of relay circuit is recommended.
SWITCH ADJUSTMENT
The following procedure can be done by putting the gauge on a
test bench or while in service.
Unscrew the cover of the electrical enclosure. Knurled head set
screws are provided at bottom for setpoint adjustment .
Rotate the screw clockwise (right) to decrease the setpoint and
counter-clockwise (left) to increase the setpoint.
One or two trials may be necessary to attain the exact setpoint.
