Operation
4.2.2.2 Ethernet LED indicators
Refer to Table 10 for a description of the Ethernet connection LED indicators.
4.2.3 Pulse output modes
The pulse unit sends an 8-µs signal each time a particle is detected. A data acquisition
system installed by the user and connected to an output channel counts the pulses. The
data can be sent in one of 2 count modes—differential or cumulative (Figure 25).
• Differential mode—a signal is sent on the first channel when a particle is between
the first and the second size thresholds. A signal is sent on the second channel when
a particle is larger than the second size threshold.
• Cumulative mode—a signal is sent on the first channel when a particle is larger than
the first or the second size threshold. A signal is sent on the second channel when a
particle is larger than the second size threshold.
Note: The count mode can be configured by the factory. The default setting is differential. Pulse
units cannot be networked.
