9.12 Pulse Output Function

The transmitter is provided with two pulse outputs which can be set up as independent outputs. Attractive

features include a double pulse output created by allowing two pulses out of phase by 0 or 0 degrees,

and a bidirectional pulse output - linked with status output signal, enabling the operator to discriminate the

direction of flow. Refer to the following topics for description of these features.

(NOTE: When the pulse output assignment, full scale flowrate, or frequency at full scale is modified, the

Counter/Totalizer will be reset.)

9.12.1 Pulse output 1

If you want to use pulse output , it is required that the following be set up.

For using bidirectional pulse output or double pulse output, be sure to set the assignment of interest.

() Setup procedure

①

Pulse output assignment (Assign) (See .. Transition chart (3) [No. --3-].)

Kind of flow is selected.

・

Mass Flow:

Mass flow

・

Volume Flow: Volumetric flow

②

Frequency of pulse output at full scale flowrate (Freq Factor) (See .. Transition chart (3)

[No. --3-].)

The frequency at the flowrate set in

③

is set up. Set it to match the measurable range of the

instrument that measures pulse output. Acceptable setting range is from 0. to 0000Hz.

③

Full scale flowrate of pulse output (Rate Factor) (See .. Transition chart (3) [No. --3-3].)

An output is generated at the frequency set in

②

when the preset flowrate is reached.

④

Low flow cutoff of pulse output (Lowcut) (See .. Transition chart (3) [No. --3-].)

When the proportion of flowrate is smaller than the low flow cutoff value - where the flowrate set

③

is set to 00% - the output is clamped at 0. Acceptable setting range is from 0.0 to 0.0%.

⑤

The state of pulse output in an error (Pulse) (See .. Transition chart () [No. ---].)

Pulse output value in an error can be selected from the following three options:

・

Zero: Pulse output is halted.

・

Hold: Pulse output immediately before an error is maintained.

・

Upscale: kHz is output. (For detail of output in an error, see 0. Error Messages.)

9.12.2 Pulse output 2

If you want to use pulse output , it is required that the following be set up.

For using bidirectional pulse output or double pulse output, be sure to set the assignment of interest.

(In the case of double pulse output, set only pulse output assignment. Invalidating parameters other

than that, pulse output is also output with the same setting as that of pulse output .)

①

Pulse output assignment (Assign) (See .. Transition chart(3) [No. ---].) Type of flow to

be assigned is selected.

・

Mass Flow:

0: Double pulse output

－

As for double pulse output, see .. Double pulse output.

As for

②

③

, and

④

below, a procedure similar to pulse output applies. See .. Pulse output ().

②

Frequency of pulse output at full scale flowrate (Freq Factor) (See .. Transition chart (3)

[No. ---].)

③

Full scale flowrate of pulse output (Rate Factor) (See .. Transition chart (3) [No. ---3].)

④

Low flow cutoff of pulse output (Lowcut) (See .. Transition chart (3) [No. ---].)

⑤

The state of pulse output in an error (Pulse) (See .. Transition chart () [No. ---].)

NOTE: For this function, the setting change is disabled in

Write Protect mode (refer to section .).
