4.2.2 Installation Procedure

IMPORTANr

When high-temperuiure fluid is being measured, radiant heal from the detector pipe surface and adjoining pipes may cause the ambient temperature of the converter to go above 6t) If the ambient lemperature goes above 60° C, try to lower the temperature by measures such as wrapping heat-insulating materials over the detector pipe and adjoining pipes.

6F8A0770

To mouiu thu LF434/J.F404, plai:c il between Itic upstream and downstream pipe flanges and tighten it with flange holts and nuts. See f igure 4,2 t Tablc4,1 and follow ihe procedure below:

1. Place one of the flange packing next to the upstream (or downstream) pipe llattge. Altgi^ the holes of the packing with those of the flange so that the holes arc not obstructed.

2, Insert the Lh’434 detector in pipeline in accordance with the flow direction arrow on the

detector.

3, Insert the bolts, one at a time, through the hole in the upstream (or downstream) pipe

flange and packing, and then through the hole of the detector flange. Then thread nuts, one at a time, on each end of the bolts, finger-tighten. This will help support the detector on one side.

4, Insert the downstream (or upstream) packing between the detector flange and the down

stream (or upstream) pipe flange. Align the holes of the packing with those of tlie flanges so that the holes are not obstructed.

5. Inert the bolts, one at a time, through the hole in the downstream (or upstream) pipe flange and packing, and tJien through the hole of the detector flange. Then thread nuts, one at a time, on each end of the holts, finger-tighten. This will help support the detector.

6. While centering Ihe detector with ihe longitudinal axis of the pipeline, tighten the bolts with a wrench diagonally across in even increrr^nis

6,2 Zero Adjustment

6F8A0770

To conduct /oro adjustJiieitl of the flowmeter, iho fluid in the delector pipe must be held still. There arc three different ways to slatl the zero adjustment:

(1) Pressing the zero adjustment switch for the model without LCD display (2) Pressing a combination of control keys for the model with LCD display

(see 8,2-ii, "Zero Adjust men I'')

(3) Sending a command signal from a HART communications device

(such as the AFIOO hand-held terminal), The following is the procedure for starting the zero adjustment for the model without LCD display,

■ Press the zero adjustment switch for more than 3 seconds.

(Note that once the 7ero adjustment is started, there is no way to cancel the zero

adjustment sequence.)

Then the Li3D indicator lights and the zero adjustment sequence will start. The zero

adjustment sequence lasts about 3 to 6 seconds, (Zero adjustment duration depends on the excitation current frequency. It lakes about 3 seconds for 24 Hz selling and about 6 seconds for 12 Hz and 6 Hz settings.)

When the zero adjustment sequence ends, the LED indicator goes off.

I’o conduct the zero adjustment, it is necessary to open the cojtverter housing cover for

internal electronics and press the switch. Observe the following precautions w'hcn you

open the housing cover:

(1) Do not open the cover in the open air unprotected against rain or wind.

If yon adjust the flowmeter in ihe rain, this can cause electric shock or damage to the llow'meler electronics. If wind blow's against the internal circuitry of the converter, output may flticttiate and fail to indicate correct measuring values.

(2) Do not conduct the zero adjustment when the ambient humidity is higli. By opening the

cover in high humidity conditions, the measuring accuracy may be reduced or damage caused to the flowmeter electronics.

jrdicare various configuration parameters. Figure 7.1 shows the front view of LCD display.

(1) Do not open the housing cover for LCD display in the open air unprotected against ruin or

wind. If you open the housing cover for LCD display in the rain, it can cause electric shock or damage to the flowmeter electronics. If wind blow-s against the internal circuitry of the converter, the output may fluctuate and fails to indicate correct measuring values.

(2) Do not open the housing cover for LCD display when the ambient humidity is high*

6F8A0770

Flow mea^surcjncni in Ihe measurement mode, checking or changing configuration parameters in ihe setting mode and a converter unit check in the calibration mode are the basic operations of the LF404 converter*

7*3*1 Müde Change

The 1.F4(I4 converter has three operation modes: measurement* setting and calibration. The system slays in the measurement mode after the power is turned on* To change (he

mode to the setting or calibration mode, press [SRT] and select the desired item using

[ ► ] and [ A ] keys. To return to the measurement mode, select “0" {MEASURE MODE) for the number column of configuration items (such as AU or B[)). See 7.4* “Configuration Items Selection Table,"

■ Measurement mode

: measures ttic process flow and displays and outputs the measured process values. The

flowmeter can measure the flow velocity, flow rates* or totalized flow. I’he flowmeter

first goes into this mode when power is turned on.

Setting mode

: used to check or change various configuration parameters used in the measurement

mode. These parameter values are displayed while checking or changing ihe.se values but the flowmeter outputs the Tieasured process values as in the measurement mode. See 7,4, “Configuration Items Selection Table" and 8.2, “Checking or Changing

Parameters" for details. Configuration items are from Al, A2, A3 to Ml.

Calibrtttion mode

: used to check the converter iniernal circuits. The internally generated simulation signal

is used to check the measuring span and excitation current value. The current output of

the flowmeter changes in acoŒtlance with the simulation signal. The stains of each

digital output is held to the value just before the system moved into the calibration

mode. Sec 7.4, “Configuration Items Selection t able" and Chapter 9, “Calibration" for

details. Configuration items are from N1 to N4,

S2A4 Rate*Of-Change Limit

6F8A0770

The riite-of-changc limit is used to eliminate high dectricftl noise contained in the process flow i^ignal.

To check electrical noise, two parameters arc defined: rate-of-change limit (set in percent value of the span) and control limit rime (set in units of seconds). Normally ihe flowmeter produces the analog output signal by sampling the flow rale signal at 1/24 (or 1/12) of a second sampling rate. If the sampled value exceeds the set rate-of-ehange limit value based on the averaged flow rate value up until Ihc sampled lime, the system will reject that sampled value and instead the averaged value including Ihe ratc-of-changc limit value in place of the rejected sampled value will be output. However, if the limit-exceeding sampled value cominues for the same flow direction for more than the preset control limit lime, that data will be used as the oulpul signal The setting ranges for these two parameters are as follows:

* Rate-of-chtmge limit

0 to 30 %/sampling rale (in increments of 0.3 %)

Where the sampling rate is either 1/24,1/12 or 1/6 of a second depending on the

excitation frequency as shown below:

Excitation frequency Sampling rale

24 Hz 1/24 sec

12IIzor6Hz 1/12 sec

- Control limit time: Ü to 20 sec (in increments of 1 second)

NOTE

If ‘*0’’ is sel in either of these parameters, the rate-of-change limit function is disabled. Proceed as follows to check or change the raie-of-change limit value and the control limit lime.
