chart recorders. Relay outputs are typi- cally sent to annunciators.

3.Relays K1 and K2 are user configur- able from the probe SETUP sub-menu (Table 5-5). Typically these are used to indicate O2 values above or below specified tolerances. OK relay is ener- gized when unit is functioning properly.

4.All wiring must conform to local and national codes.

a. Mechanical Installation

1.The microprocessor board has a se- lector for voltage or current operations. Figure 2-10shows switch orientation. In voltage mode, output is 0-10 V. In the current mode, the output can be configured 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

The outline drawing of the heater power supply enclosure in Figure 2-13shows 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).
