3.6.5 Pulse wiring
Counters with the pulse output option send a pulse signal when a particle is detected. An external pulse counter or data acquisition system counts the pulses as particles. Pulse units have two output channels (Ch 1 and Ch 2). Channel 1 reads the smallest size particles. Channel 2 can be set for a larger size using the setup utility program. The status output, when asserted, indicates that the particle counter needs attention.
Pulse units cannot be used in a network configuration. The address must always be set
to 1 (Table 8 on page 33). Refer to Figure 13 and Table 4 to install a particle counter with pulse output.
