This document provides information for setting Honeywell controllers DC230B-EE-20-10-0A00000-00-0 (Figure 1) when used to indicate levels in Heatec fuel tanks. It applies to Heatec vertical fuel tanks equipped with Siemens Sitrans P, Series DSIII pressure transmitters.

The controller indicates levels of fuel in the tank. Levels are shown in feet, measured above the level where the transmitter is installed. The transmitter is installed 1.33 feet (16 inches) above the bottom of the tank. Thus, there are approximately 941 gallons of fuel in the tank when the controller indicates zero.

The controller automatically activates an alarm when the tank is 90 percent full. The controller also activates an alarm when the level is at zero.

Honeywell controllers purchased from Heatec are normally set at our factory and require no further setup. However, the controller can be reset in the field using the information shown in Figure 2.

Honeywell UDC 2300 Universal Digital Controller User Manual is furnished with each controller. Please refer to this manual for instructions on using the buttons to set the controller.

Please refer to Heatec Tec-Note, Publication 5-04-115 for more information on levels and the Siemens pressure transmitter.
