3.3 Limit Switch Operational Setup
Warning! Do not apply power to the transmitter until all connections have been made and
the cover of the transmitter has been replaced.
The limit switches normally are configured in arrays of 2 or 4 switches. To set these switches
proceed as follows:
1. Remove power or obtain a hot work permit before removing the transmitter cover.
2. Determine which switch sets which specific limit to be selected. (High, Low, etc.)
3. Use the indicator dial as a reference. Align the lobe on the cam to the selected limit. Spring
washers are used to keep the cams from moving.
Note If there are two scales on the dial pointer, it is painted the color of the scale used. If
the dial pointer is red, use red numbers, and if the pointer is black, use the black numbers.
4. After calibration and alignment of the cam, loosen the slotted drive coupling set screw
using an Allen wrench. Set the transmitter to the actual liquid level in the tank by rotating
the field adjust knob located at the end of the shaft.
5. Tighten the Allen screw on the drive shaft coupling and install the explosion proof cover.
