Unit Options

Two banks of configuration switches (S1, S2 and S3, see Figure 2 and 3) are used to select advanced alarm reporting features (see Tables 2, 3 and 4).

Errored Seconds (ES) Alarm

The locations shown in Figure 4 are monitored for errored seconds and counts are maintained for each location.

If any of these counts exceed the ES programmed threshold (see Tables 1 and 2) an alarm will be generated. This alarm threshold and the alarm type (minor or major) can be programmed by setting switches S1 and S2 (Figure 2) to the appropriate positions, according to Tables 1 and 2.

The alarm thresholds are for the 15-minute registers only, and the 15-minute ES counts are zeroed at each 15-minute boundary. The ES alarm threshold and alarm type can also be configured in the Craft interface Options Setup screen.
