Option Card Totalizer/
Frequency Outputs
Complete the following steps to set up the four totalizer/frequency
outputs of an option card installed in Slot x:
1. Press
[F1]-[F4]
to set up outputs A, B, C or D, respectively.
Note:
The set up of output A is used as an example. Identical
procedures would be used to set up the other outputs.
2. At the Slot X Pulse Out prompt, press
[F1]
to disable output A and
return to the previous prompt, or press
[F2]=FREQ or [F3]
=
TTLZR
to
designate output A as a frequency or a totalizer output,
respectively.
3. Use the [
←]
and [
→]
and
[F1]-[F4]
keys to select a Channel option
for the data source, as shown in Table 1-20 on page 1-47.
Proceed to step 4 below for instructions on programming a frequency
output or to step 9 on the next page for instructions on programming a
totalizer output. If the selected output was disabled above, skip both
sections.
Programming a Frequency
Output
This choice produces a frequency pulse that is proportional to the
output measurement.
4. Use the [
←]
and [
→]
and
[F1]-[F4]
keys to specify the desired
Output Measurement parameter. See Table 1-21 on page 1-47 for a
description of the available options.
Note:
The measurement units that appear in these prompts are those
selected in the
SYSTM
menu earlier in this chapter.
5. Enter a value for the Base (low end) of the frequency output range
and press
[ENT]
.
6. Enter a value for the Full (high) end of the frequency output range
and press
[ENT]
.
7. Enter a value between 1 and 10,000 for the Full Scale Frequency
and press
[ENT]
.
8. Use the
[F1]-[F4]
keys to select the desired Error Option , the way
the display responds during an error condition. Available options
are shown in Table 1-23 below. Then skip to step 12 on the next
page.
Table 1-23: Error Response Options for Frequency Output
Option Display Response
HOLD Holds the last “good” reading.
LOW Forces the outputs to the low setpoint.
HIGH Forces the outputs to the high setpoint.
OTHER Allows user to enter Hertz error level.
