1.The microprocessor board has a se- lector for voltage or current operations. Figure 2-9 shows switch orientation. In voltage mode, output is 0-10 V. In the current mode, the output can be con- figured from the SETUP menu to be 0- 20 mA or 4-20 mA.

2.The analog output and relay outputs are programmed by the user as needed. The analog output is typically sent to recording equipment such as chart recorders. Relay outputs are typi- cally sent to annunciators.

The outline drawing of the heater power supply enclosure in Figure 2-12 shows mounting centers and clearances. The NEMA 4X enclosure is designed to be mounted on a wall or bulkhead. The heater power supply should be installed no further than 150 feet (45 m) from the probe. The heater power supply must be located in a location free from significant ambient tem- perature changes and electrical noise. Am- bient temperature must be between -20° and 140°F (-30° and 60°C).
