Binary Input

The binary inputs include the Analysis Start/Stop input and the level sensors that are included in the Fail Safe
accessory. Some of the optional level sensors are located in the sample cups, and they are used to detect when
the flow of any of the sample streams has stopped. The other level sensors are located in the Check Standard,
Acid, Oxidizer, and Dilution Water carboys.
Press the Binary Input button to display the Binary Input screen (Figure 78). If the Fail Safe accessory is not
installed, the Level Sensors button includes a "Not Installed" notation. Otherwise, each level sensor should be
accessed and its float should be moved up and down. The screen will indicate the float position by alternating
between "High Liquid" and "Low Liquid." The level sensors in the sample cups may be accessed by unscrewing
the stainless steel cover from the plastic sample cups.
The Analysis Start/Stop binary input is located on pins 1 and 2 in terminal block, TB2 (see Table 2 on page "Binary
Input (TB2)" on page 75.) Figure 8 on page 79 and Figure 9 on page 79 illustrate ways of wiring the input. If the
Analysis Start/Stop binary input is activated when the Binary Input screen appears, the Analysis Start/Stop
button will change from Off to On. However, the Analyzer will not start or stop analysis.
