5. Totalizer pulse output. Puts out a timed pulse for each totalizer count. This
signal is intended to go to a remote totalizer. The pulse width ON time is
selectable to be either 500 +/- 84
m
sec, 2 msec, or 50 msec. The minimum
OFF time is the same as the ON time. Regardless of the totalizer display
mode selected for the Eclipse (i.e. divide by 1, 10, or 100), the totalizer pulse
output operates in the divide by 1 mode. The totalizer pulse output has a
9,999 count buffer. Because of the nature of this output, it is recommended
that a transistor output be used for this function.
Analog Output Option Board
Sometimes known as analog retransmission, the installer can assign the output to
follow displayed rate, or total, or batch count. Both 4-20 mA and 0-10V outputs are
given; however they are not independently programmable. The installer programs
not only the assignment, but the offset and full scale values. Both outputs follow the
assigned count or rate and go from minimum value (4 mA and 0V) to maximum
value (20 mA and 10V) as the displayed count or rate goes from offset value to full
scale value. Both outputs are electrically isolated from all other circuitry inside the
Eclipse.
RS 485 Serial Communications Option Board
This option board allows a host device, such as a computer, to download and read
programming selections, and to perform most of the run mode operator functions
such as read count and rate, enter setpoints, reset counters, and start and stop
batch delivery.
