2.3. OPERATOR INFORMATION AND FUNCTIONS

In general, the pressure indicator will always act at Operator level. The information displayed depends on the SETUP-settings. Although the refresh-rate of the display might be slow (due to power-management functions), the sensor signals will be processed at all times. After pressing a key, the display will be updated very fast during 30 seconds after which it will slow-down again.

Fig. 3: Example display when the information is selected manually.

Fig. 4: Example display information when sensor A and B are displayed simultaneou sly.

For the Operator, the following functions are available:  Display pressure

The actual pressure is displayed with the 17mm digits at the upper line. When "-------" is shown, the pressure is too high to be displayed. The arrows  indicate the increase / decrease of the pressure. Depending on the settings, both pressures can be displayed simultaneously where the input number is displayed as "A" or "b". When they are not displayed at the same time, then the information can be selected manually or it will be displayed automatically with an interval time of 6 seconds.

 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.

Matrix structure SETUP-level:

SCROLLING THROUGH SETUP-LEVEL

Selection 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 function. Additionally, each function is expressed with a keyword.

After selecting a sub-function, the next main function is selected after scrolling through all "active" sub-functions (e.g. 1, 11, 12, 13, 14, 1, 2, 3, 31 etc.).

HF151AEN_v0501_04

Page 11

To change or a select a value or value:

To change a value, use  to select the digits and  to increase that value. To select a setting, both  and  can be used. When the new value is not valid, the increase sign or decrease-sign will be displayed while you are programming.

When data is altered but ENTER is not pressed, then the alteration can still be cancelled by waiting for 20 seconds or by pressing ENTER for three seconds: the PROG-procedure will be left automatically and the former value reinstated.

Note: alterations will only be set after ENTER has been pressed!

To return to OPERATOR-level:

In order to return to the operator level, PROG will have to be pressed for three seconds. Also, when no keys are pressed for 2 minutes, SETUP will be left automatically.

SETUP - 11 determines the measurement unit for pressure measured with sensor A (completely independent of sensor B).

The following units can be selected: mbar - bar - psi - no unit Alteration of the measurement unit will have consequences for operator

and SETUP-level values. Please note that the Span has to be adapted as well; the calculation is not done automatically. This setting determines for pressure the number of digits following the decimal point. The following can be selected:

00000 - 1111.1 - 2222.22 - 3333.333 With the span, the sensor signal is converted to a pressure.

The span for pressure is determined on the basis of the selected measurement unit at 20mA. Enter the span in whole numbers (decimals are set with SETUP 14). The more accurate the span, the more accurate the functioning of the system will be.

Example 1 Calculating the span for level

Let us assume that the sensor generates 20mA at a pressure of 18.95 Bar and the selected unit is "mbar". The span is 18,950 mbar, Enter for SETUP - 13: "18950" and for SETUP - 14 - decimals span "0".

This setting determines the number of decimals for Span (SETUP 13). The following can be selected:

0 - 1 - 2 - 3 - 4 - 5 - 6 Please note that this SETUP - influences the accuracy of the Span

indirectly. This setting has NO influence on the displayed number of digits for "pressure" (SETUP 12)! Enter here the "not measured" pressure, in case a pressure transducer is not placed in the bottom of a container but somewhere halfway for example. A negative offset can be entered by pressing the middle and right button simultaneously.

4 - POWER MANAGEMENT

When used with the internal battery option, the user may hold the concern of reliable measurement over a long period of time. The F151-A has several smart power management functions to extend the battery life time significantly. Two of these functions can be set:

LCD NEW 41

BATTERY-MODE 42

The calculation of the display-information influences the power consumption significantly. When the application does not require a fast display update, it is strongly advised to select a slow refresh-rate. Please understand that NO information will be lost. The following can be selected:

Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.

Example 3: Battery life-time

battery life-time with FAST update: about 2 years. battery life-time with 1 sec update: about 5 years.

Note: after a button has been pressed by the operator - the display refresh-rate will always be FAST during 30 seconds. When "OFF" is selected, the display will be switched-off after 30 seconds and will be switched-on as soon as a button has been pressed.

The unit has two modes: operational or shelf. After "shelf" has been selected, the unit can be stored for several years; it will process the input signal, the display is switched-off but all settings are stored. In this mode, power consumption is extremely low. To wake-up the unit again; press the SELECT-key twice.

The F151-A can process the (0)4-20mA signal of sensor A in two ways:

 Interpolation: the signal is processed linear

 Square root: for differential pressure

R = S x I

R = S √ I

where: R = Rate: the calculated pressure S = Span: the maximum pressure at 20mA. The span is

programmed with setting 13 for pressure

I = Input: the scaled analog value; in these formulas value 0 (zero)

for (0)4mA and value 1 (one)

The analog output signal of a sensor does mirror the actual pressure. This signal is measured several times a second by the F151-A. The value measured is a "snap-shot" of the real pressure as it will be fluctuating. With the help of this digital filter a stable and accurate reading can be obtained while the filter level can be set to a desired value. The filter principal is based on three input values: the filter level (01-99), the last measured analog value and the last average value. The higher the filter level, the longer the response time on a value change will be. Below, several filter levels with there response times are indicated:

TIME IN SECONDS

To ignore e.g. vibration, a low-pressure cut-off can be set as percentage over the full range of 16mA (or 20mA / 10V). When the analog value is less then required with this setting, the signal will be ignored. The cut-off value can be programmed is the range 0.0 - 99.9%.

Examples:

CUT-OFF

With this setting it is possible to calibrate the input value for (0)4mA as the signal from the sensor might not be exact 4.0 mA (or 0.0 mA) at minimum pressure. This function will measure the real output value at minimum pressure.

 Warning: be very sure that the offered signal is correct

before the calibration is executed as this function has major influences on the accuracy of the system!

After pressing PROG, three settings can be selected:  CALIBRATE: with this setting, the input will be calibrated with the

actual "(0)4mA" value. After pressing enter, CAL SET will be displayed as soon as the calibration is completed. From that moment, the analog value must be more than the calibrated value before the signal will be processed.

4.4. INSTALLING THE HARDWARE

4.4.1. INTRODUCTION

 Electro static discharge does inflict irreparable damage to electronics! Before installing or

opening the unit, the installer has to discharge himself by touching a well-grounded object.

 This unit must be installed in accordance with the EMC guidelines (Electro Magnetic

Compatibility).

Aluminum enclosures

 When installed in an aluminum enclosure and a potentially explosive atmosphere requi ring

apparatus of equipment protection level Ga and Da, the unit must be installed such that, even in the event of rare incidents, an ignition source due to impact or friction sparks between the enclosure and iron/steel is excluded.

 Do ground the aluminum enclosure properly as indicated, if the F151-A has been supplied with

the 115-230V AC power-supply type PM. The green / yellow wire between the back-casing and removable terminal-block may never be removed.

Fig. 8: Grounding aluminum enclosure with type PM 115-230V AC.

FOR INSTALLATION, PAY EMPHATIC ATTENTION TO:

 Separate cable glands with effective IP67 (NEMA4X) seals for all wires.  Unused cable entries: ensure that you fit IP67 (NEMA4X) plugs to maintain rating.  A reliable ground connection for both the sensor, and if applicable, for the metal casing.  An effective screened cable for the input signal, and grounding of its screen to terminal 9 (GND)

or at the sensor itself, whichever is appropriate to the application.

4.4.2. VOLTAGE SELECTION SENSOR SUPPLY

For Intrinsically Safe applications: read chapter 5.

Battery powered and output loop-powered applications:

Terminal 11 provides a limited supply voltage of 3.2 V DC which is not sufficient to power a (0)420mA or 0-10V sensor.

Option PD-PM: Sensor supply: 3.2V - 8.2V - 12V or 24 V:

With this option, a real power supply for the sensor is available. The sensor can be powered with 8.2

- 12 or 24 V DC (max. 50mA@24V). The voltage is selected by the three switches inside the enclosure.

 Warning: be sure that all the leads to the terminals are disconnected from the unit when

the internal plastic protection cover has been removed !

 HIGH VOLTAGE 400V !! NEVER connect the mains power supply to the unit when the

plastic protection cover has been removed !!!

First, remove the terminal strip(s) after which the internal plastic cover can be removed. The switches are located in the top left corner (option PD) or on the right hand (option PF / PM) as indicated:

diagrams. Protection against accidental contact is no longer assured when the housing cover is removed or the panel cabinet has been opened (danger from electrical shock). 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.

The F151-A does not require special maintenance unless it is used in low-temperature applications or surroundings with high humidity (above 90% annual mean). It is the users responsibility to take all precautions to dehumidify the internal atmosphere of the F151-A in such a way that no condensation will occur, for example by placing dry silica-gel sachet in the casing just before closing it. Furthermore, it is required to replace or dry the silica gel periodically as advised by the silica gel supplier.

Battery life-time:

It is influenced by several issues as:

 Display update: fast display update has major influence; SETUP 61.  communication.  Low temperatures; the available power will be less due to battery chemistry.

Note: It is strongly advised to disable unused functions.

Check periodically:

 The condition of the casing, cable glands and front panel.  The input/output wiring for reliability and aging symptoms.  The process accuracy. As a result of wear and tear, re-calibration of the sensor might be

necessary. Do re-enter any subsequent Span alterations.

 The indication for low-battery.  Clean the casing with soapy-water; don't use any aggressive solvents as these might damage

the polyester coating.

APPENDIX B: PROBLEM SOLVING

In this appendix, several problems are included that can occur when the F151 -A is going to be installed or while it is in operation.

The password is unknown:

If the password is not 1234, there is only one possibility left: call your supplier.

ALARM

When the alarm flag starts to blink an internal alarm condition has occurred. Press the " sele ct button" several times to display the 5-digit error code. The codes are:

0001: irrecoverable display-data error: data on the display might be corrupted. 0002: irrecoverable data-storage error: the programming cycle might have gone wrong: check

programmed values.

0003: error 1 and error 2 occurred simultaneously The alarm condition will almost certainly be handled internally and if all mentioned values still appear

correct, no intervention by the operator is needed. If the alarm occurs more often or stays active for a longer time, please contact your supplier.

OTHER F151-A VARIABLES FOR COMMUNICATION

READ PRESSURE: The value of pressure read using communication might differ from the value

displayed. This is due to the fact that the display can only display up to seven digits (e.g. when two decimals are selected for pressure and pressure has a value of 123456,78 the display will show 23456,78 while communication will read a “pressure” of 12345678 and a “pressure decimals” of 2).

WRITE PRESSURE: Impossible.

Pressure A - variable number 572 (23Ch) – 4 bytes Pressure B - variable number 588 (24Ch) – 4 bytes
