1. INTRODUCTION

1.1. SYSTEM DESCRIPTION OF THE F127-P-EL

Functions and features

The flowcomputer Model F127-P-EL is a microprocessor driven instrument for the calculation of

standard volumetric flow or mass flow for differential flow measurement applications using flow

equations.

This product has been designed with a focus on:

ultra-low power consumption to allow long-life battery powered applications (option PB),

intrinsic safety for use in hazardous applications (option XI),

several mounting possibilities with ABS or aluminum enclosures for harsh industrial

surroundings,

ability to process all types of flowmeter signals,

transmitting possibilities with analog and communication (option) outputs.

Flowmeter and temperature input

This manual describes the unit with a pulse type input from the flowmeter "-P version".

Two flowmeters with a passive or active pulse, Namur or coil signal output can be connected to the

F127-P-EL. To power the sensor, several options are available.

This unit has two analog (0)4-20mA temperature inputs “-TA version ”. Other versions are available

to process 0-10V or PT100 temperature signals.

Standard output

Configurable passive linear 4-20mA analog output with 10-bits resolution mirroring the

calculated differential flowrate at standard conditions. Flowrate levels as well as the minimum

and maximum signal output can be tuned.

Fig. 1: Typical application for the F127-P-EL.

HF127PEN_EL_TA_v0501_04

Configuration of the unit

The F127-P-EL was designed to be implemented in many types of applications. For that reason, a

SETUP-level is available to configure your F127-P-EL according to your specific requirements.

SETUP includes several important features, such as K-factors, Span, measurement units, signal

selection etc. All setting are stored in EEPROM memory and will not be lost in the event of power

failure or a drained battery.

To extend the battery-life time (option), please make use of the power-management functions as

described in chapter 3.2.3.

Display information

The unit has a large transflective LCD with all kinds of symbols and digits to display measuring units,

status information, trend-indication and key-word messages.

Flowrate and totals can be displayed either with the small 8mm digits or with the 17mm digits.

A backup of the total and accumulated total in EEPROM memory is made every minute.

Options

The following options are available: isolated or active 4-20mA / 0-10V / 0-20mA analog output, full

Modbus communication RS232/485 (also battery powered), intrinsic safety, power- and sensor-

supply options, panel-mount, wall-mount and weather-proof enclosures, flame proof enclosure.

Important: for Model F127-P-EL-TA, option PM (80-230V AC power supply) is not available.

2. OPERATIONAL

2.1. GENERAL

The F127-P-EL may only be operated by personnel who are authorized and trained by

the operator of the facility. All instructions in this manual are to be observed.

Take careful notice of the " Safety rules, instructions and precautionary measures " in

the front of this manual.

This chapter describes the daily use of the F127-P-EL. This instruction is meant for users /

operators.

2.2. CONTROL PANEL

The following keys are available:

Fig. 2: Control Panel.

Functions of the keys

This key is used to program and save new values or settings.

It is also used to gain access to SETUP-level; please read chapter 3.

This key is used to SELECT accumulated total and temperature.

The arrow-key is used to increase a value after PROG has been pressed

or to configure the unit; please read chapter 3.

Press this key twice to CLEAR the value for total.

The arrow-key is used to select a digit after PROG has been pressed or to

configure the unit; please read chapter 3.

2.3. OPERATOR INFORMATION AND FUNCTIONS

In general, the F127-P-EL will always function at Operator level. The information displayed depends

upon the SETUP-settings. All pulses generated by the connected flowmeter are measured by the

F127-P-EL in the background, whichever screen refresh rate setting is chosen. After pressing a key,

the display will be updated quickly during a 30 second period, after which it will slow down again.

Fig. 3: Example of display information during process.

For the Operator, the following functions are available:

Display calculated differential flowrate and calculated differential total

This is the main display information of the F127-P-EL. After selecting any other information, it

will always return to this main display automatically.

Total is displayed on the upper-line of the display and flowrate on the bottom line.

It is possible to display flowrate only with the large 17mm digits; in this instance press the

SELECT-key to read the total. When "-------" is shown, then the flowrate value is too high to be

displayed. The arrows indicate the increase/decrease of the flowrate trend.

If the consumption is very low, it might be that a stable low flowrate is displayed and and a

stable totalisation; this is due to the settings of the unit.

Clear total

The value for total can be re-initialized. To do so, press CLEAR twice. After pressing CLEAR

once, the flashing text "PUSH CLEAR" is displayed. To avoid re-initialization at this stage,

press another key than CLEAR or wait for 20 seconds.

Re-initialization of total DOES NOT influence the accumulated total.

Display calculated differential accumulated total

When the SELECT-key is pressed, total and accumulated total are displayed. The

accumulated total cannot be re-initialized. The value will count up to 99,999,999,999. The unit

and number of decimals are displayed according to the configuration settings for total.

Display line temperature and calculated flowrate INLET / OUTLET

After pressing SELECT, the actual INLET / OUTLET temperature is displayed at the top line

of the display. At the bottom line, the calculated INLET / OUTLET flowrate is displayed

together with the measuring units for flowrate and temperature.

Low-battery alarm

When the battery voltage drops, it must be replaced. At first "low-battery" will flash, but as

soon as it is displayed continuously, the battery MUST be replaced shortly after!

Only official batteries may be used, or else the guarantee will be terminated. The remaining

lifetime after the first moment of indication is generally several days up to some weeks.

Fig. 4: Example of low-battery alarm.

Alarm 01-03

When "alarm" is displayed, please consult Appendix B: problem solving.

3. CONFIGURATION

3.1. INTRODUCTION

This and the following chapters are exclusively meant for electricians and non-operators. In these,

an extensive description of all software settings and hardware connections are provided.

Mounting, electrical installation, start-up and maintenance of the instrument may only

be carried out by trained personnel authorized by the operator of the facility. Personnel

must read and understand this Operating Manual before carrying out its instructions.

The F127-P-EL may only be operated by personnel who are authorized and trained by

the operator of the facility. All instructions in this manual are to be observed.

Ensure that the measuring system is correctly wired up according to the wiring

diagrams. The housing may only be opened by trained personnel.

Take careful notice of the " Safety rules, instructions and precautionary measures " in

the front of this manual.

3.2. PROGRAMMING SETUP-LEVEL

3.2.1. GENERAL

Configuration of the F127-P-EL is done at SETUP-level. SETUP-level is reached by pressing the

PROG/ENTER key for 7 seconds; at which time, both arrows will be displayed. In order to return

to the operator level, PROG will have to be pressed for three seconds. Alternatively, if no keys are

pressed for 2 minutes, the unit will exit SETUP automatically.

SETUP can be reached at all times while the F127-P-EL remains fully operational.

Note: A pass code may be required to enter SETUP. Without this pass code access to SETUP is

denied.

To enter SETUP-level:

Matrix structure SETUP-level:

SCROLLING THROUGH SETUP-LEVEL

Selection of function-group and function:

SETUP is divided into several function groups and functions.

Each function has a unique number, which is displayed below the word "SETUP" at the bottom of

the display. The number is a combination of two figures. The first figure indicates the function-group

and the second figure the sub-function. Additionally, each function is expressed with a keyword.

After selecting a sub-function, the next main function is selected by scrolling through all "active" sub-

functions (e.g. 1, 11, 12, 13, 14, 1, 2, 3, 31 etc.).
