7.1 Keypad and display
layout

Keypad The keypad is used to set the flowmeter. The function of the keys are as follows:

Display

TOP UP KEY This key (hold 2 sec.) is used to switch between operator

menu and setup menu. In the converter setup menu, a short
press will cause a return to the previous menu.

FORWARD KEY This key is used to step forward through the menus. It is the

only key normally used by the operator.

BACKWARD KEY This key is used to step backward through the menus.

CHANGE KEY This key changes the settings or numerical values.

SELECT KEY This key selects the figures to be changed.

LOCK/UNLOCK KEY This key allows the operator to change settings and gives

access to submenus.

The display is alphanumerical and indicates flow values, flowmeter settings and error messsages.

The upper line is for primary flow readings and will always show either mass flowrate, volume
flowrate, density, temperature, totalizer 1 or totalizer 2. The line is divided into 3 fields.

S: Sign field
P: Primary field for numerical value
U: Unit field

The center line is the title line (T) with individual information according to the selected operator or
setup menu.

The lowest line is the subtitle line (ST) which either will add information to the title line or keep
individual information independent of the title line.

7.2 Menu build-up

The menu structure of a specific type of transmitter is shown in a menu overview map.
Details of how a specific parameter is set is shown in a menu detail map for the specific parameter.
The menu structure is valid for the title and subtitle line only. The upper line is for primary readings
only and will always be active with either mass flow rate, volume flowrate, density, temperature,
totalizer 1 or totalizer 2.

The menu is built up in two parts. An operator menu and a setup menu.

Operator menu

The operator menu is for daily operation. The operator menu is customized in the operator menu
setup. The signal converter always starts in the operator menu no. 1. The page forward and page
backward keys are used to step through the operator menus.

Setup menu

The setup menu is for commissioning and service only.

The setup menu is accessed by pressing the top up key for 2 seconds. The setup menu will operate
in two modes:

- View mode

- Setup mode

View mode is a read only mode. The pre-selected settings can only be scanned.

Setup mode is a read and write mode. The pre-selected settings can be scanned and changed.

Access to the setup mode is protected with a password. The factory set password is 1000.

Access to a submenu in the set up menu is gained by the lock key. A short press on the top up key
will bring back the previous menu. A long press (2 sec.) on the top up key will exit the setup menu
and bring back the operator menu no. 1.

7.2.1 Password

Commissioning

The SETUP MENU can be operated in two different modes:

VIEW MODE (Read only)
CHANGE MODE (Read and write mode)

The view mode is always accessed by pressing the forward key when in the password menu.

Access to change mode is protected by a user code. The user code is factory set to 1000, but can
be changed to any value between 1000 and 9999 in the change password menu.

The factory setting of 1000 can be re-established as follows:

- Switch off power suppply

- Press the TOP UP key while switching on the power supply

The user code is reset to 1000.

Menu description

Setting of min./max.
values and units

Example; programming

of max. mass flow

The basic setting menu is used for basic configuration of the mass flow meter with a choice of units,
minimum and maximum limits for display and analog/digital outputs for all measurement
parameters, i.e. mass flow, volume flow, fraction, temperature and density.

Numerical values are entered by placing the cursor in the field that is to be set using the SELECT
key. Press unlock and the value can be changed using the change key. The desired value is locked
by activating LOCK.

Positioning of the decimal point is carried out by placing the cursor below the decimal point using
the SELECT key. The position can be set using the set key. The LOCK key is activated and the
decimal point is now positioned.

Selecting the unit: Place the cursor below the unit using SELECT key. Set the desired unit using
CHANGE key. Activate the LOCK key to save the setting. Place the cursor below the time scale
using SELECT key and choose the desired time scale using CHANGE, then save the desired value
by activating the LOCK key.

The maximum and minimum values set will then apply to all current and frequency/pulse outputs,
e.g. where the min. value will correspond to 0/4 mA depending on the setting of the current output
and the max. will correspond to 20 mA.

As example we want to change the default setting of the maximum mass flow on a CMF-A from
20 Kg/h to .45 lb/min.

Setting the totalizer

Setting the low-flow cut-off

Setting the empty pipe limit

Setting the noise filter

Setting the error level

The instrument is equipped with two independent totalizers that can be set for totalizing mass flow,
fraction A, faction B or volume.

Forward: only flow in a positive direction is totalized.
Reverse: only flow in a negative flow direction is totalized.
Net: the total net flow is measured.

In certain applications flow signals are not required below a given flow. In this menu a
0 to 10% cut-off of the maximum flow can be selected. By default the meter is set to 1.5%.

If detection of an empty pipe or of a density value is needed, it can be set under this menu option.
If the set density value is measured this will activate a relay or the digital output. In addition will
be recorded in the error log.

The instrument carries out signal processing internally using a patented FFT (Fast Fourier
Transformation) algorithm. This technology allows noisy sensor signals to be filtered. For
example, if the instrument is exposed to a strongly pulsating flow, varying pumping frequencies
or strong pressure gradient, etc. this can in certain cases result in noise on the pick-up signals,
with measurement error as a result. This measurement error can be reduced by increasing the
filtration under the menu option noise filter. Setting 5 represents the maximum possible filtration
and setting 1 represents the minimum possible filtration.

The instrument contains a particularly informative error monitoring system that the user can
configure according to need. The system is described in more detail in the section on error
handling.

The current output should be set to off when not used, otherwise an error will be pending if the meter
detects an open loop.

Frequency

The digital output menu can be used for generating a frequency proportional output signal, for
pulse signal (totalizing), indicating error level/number, limit or flow direction or as batch output. Only
one function can be implemented for each output section.

2 separate set points

Limit switches are available for both digital and relay output and can be used for mass flow, fraction,
volume flow, temperature or density.

To set the output to show flow direction then select: 1 set point at 0% flow; hysteresis 5%.

To have a flow, temperature, density or fraction area monitored via the digital output then select
2 set points.

If 2 set points have to activate two separate outputs, each set point has to be selected individually
one for digital output and the other for relay output.
