5. LCD KEY-PAD OPERATION: DATA ENTRY AND

CONFIGURATION

5.1 Display Indications

Initially, after the power is first turned on, the Banner Screen is shown for 2 sec­onds, then device firmware and EEPROM data base table revisions on the first line,
communication interface type on the second line, baud rate and RS-485 hexadec­imal address value on third and fourth lines are shown for another 2 seconds.
Subsequently, the actual process information (PI) is displayed.

Figure 5.1: TIO Firmware and Communication Interface Info Screen

Based on device configuration (Device Function as flow meter or flow controller),
different parameters may be displayed in the Process Information (PI) screen by
pressing the UP or DN pushbuttons.

Process Information screens can be configured to be static or dynamic (see
Paragraph 5.3.11 “Display Menu”). Using Screen Mask settings user can enable
(unmask) or disable (mask) up to 4 different process information combinations
(see Figure 5.4). In the Static Mode the UP button pages through the PI screens
in the forward direction, the DN button pages through the PI screens in the reverse
direction. When the last PI screen is reached, the firmware “wraps around” and
scrolls to the initial PI screen once again.

In the Dynamic Display Mode, firmware initiates automatic screen sequencing with
user- adjustable screen Cycle Time (see Paragraph 5.3.11 “Display Menu”). When
the last PI screen is reached, the firmware “wraps around” and scrolls to the ini­tial PI screen once again.

The Set Point value can be adjusted locally using LCD/keypad, remotely via RS­232/RS-485 digital interface or can be programmed in advance using user-preset
programs of up to sixteen steps (Program Set Point Mode).

a) Adjusting Set Point value using local LCD/keypad

Current Set Point value is displayed on the second line of the main PI screen, next
to the ‘S’ character.

Pressing the ENT button while in the main PI screen will activate Set Point adjust­ment mode. The first character of the Set Point value will start to flash. Use UP or
DN button to increment / decrement digit value from 0-9. Use RIGHT or LEFT but­ton to move cursor to another digit position. When desired Set Point value is
entered use the ENT button to accept (save in the EEPROM) new Set Point value.

If at the end of the Set Point value entry the ESC button is pressed instead ENT,
the original Set Point value will be restored and Set Point adjustment mode will be
deactivated. To exit from the Set Point adjustment mode before Set Point value is
accepted, press the ESC button.

b) Controlling Set Point value using Program Set Point mode

To activate Program Set Point mode the following must to be done:

1. Program Set Point mode must be Enabled (see paragraph 5.3.16 a).

2. Program Loop parameter must be set to desired value (On/Off).

3. Program Run parameter must be set to “On” (default settings is Off).

NOTE: Since the Set Point value entered via local LCD/keypad is
stored in the non-volatile memory (EEPROM), it will be executed on
the next device power up event.

,

NOTE: If the Program Set Point mode is enabled and the program is
running, the Set Point value can be changed at any moment by the
execution of the next active step. The Set Point entered via local
LCD/keypad can be also changed via digital RS-232/RS-485 interface.

,

S: 100.0 litr/min

T1: 1589324.5 litr

17

NOTE: Before executing, the program should be entered in the
program table (see Paragraph 5.3.16)

,

NOTE: While Program Set Point mode is running, the current Set
Point value also can be changed from local LCD/keypad and digital
RS-232/RS-485 communication interface. In this case, new Set Point
value will be kept only until the next successive program step is
executed.

,

As shown in the above drawing the Program Run parameter can be toggled “On”
or “Off” by pressing the RIGHT and LEFT keypad buttons, while PI screen #4 is
active. If Program Run status parameter is set to “Off”, the program execution will
pause and current SP value will freeze until Program Run status parameter is set
to “On”.

5.2 Menu Structure

The diagram on the Figure 5.7 gives a general overview of the standard top-level
display menu structure when running firmware version A001. The ESC pushbutton
is used to toggle between the Process Mode (PI screens) and the Setup menus.

UP and DN buttons must be used to move through the menu items. When the last
item in the menu is reached, the menu “wraps around” and scrolls back to the
beginning of the menu items list. Similarly, when the first menu item is highlight­ed and the UP button is pressed, the menu “wraps around” and scrolls down to
the end of the menu item’s list.

All process configuration parameter’s settings are password-protected. In order to
access or change them, Program Protection should be disabled. Each time the
device is powered up, the Program Protection is enabled automatically. By default,
the device is shipped from the factory with the Program Protection (PP) password
set to Zero (PP Disabled). If PP password is set to Zero (Disabled), entering a PP
password is not required. A subsequent screen will appear and the Program
Protection menu item will be selected:

Figure 5.5

Pressing the UP or DN button to select the Disabled option and then the ENT but-
ton to save settings will disable program protection.

If PP password is set to any value more than Zero, the firmware will prompt with
“Enter PP Password” (see Figure 5.6). User must enter up to 3 digits program
protection code, in order to be able to access password protected menus. Once
the correct password is entered, Program Protection is turned off until the unit is
powered up again.

Figure 5.6

5.3 Parameter Entry

There are two methods of data entry: • Direct numerical number entry.

• Tabular Input from a table menu.

If the menu with direct numerical entry is selected use the UP or DN button to
increment / decrement digit value from 0-9. Use the RIGHT or LEFT button to
move the cursor to another digit position. When the desired value is entered, use
ENT button to accept (save in the EEPROM) the new value.

19

If the menu with tabular entry is selected, the available menu options can be set
with the UP and DN buttons and are accepted by pressing the ENT button.

5.3.1 Submenu “Change PP Password”

In order to get access to “Change PP Password” menu, Program Protection must
be disabled. If PP password is set to Zero (Disabled), entering PP Password is not
required and PP can be disabled from “Program Protection” menu (see Figure

5.5). If PP Password is set to any value more than Zero, the firmware will prompt
with “Enter PP Password” (see Figure 5.6). User must enter program protection
code (up to 3 digits). If PP password is lost or forgotten, contact the factory or
your distributor.

NOTE: During data entry the input vales are checked for
acceptability. If data is not acceptable, it is rejected and a message
is generated indicating that the new data has not been accepted.

5.3.3 Submenu “Measuring Units”

Use the “Engineering Units and K-Factor Menu” to navigate to “Measuring Units”
menu option. This option allows configuration of the flow meter/controller with the
desired units of measurement. These are global settings and determine what
appears on all process information screens and data log records. Units should be
selected to meet your particular metering needs. A total of 47 different volumetric
and mass-based engineering units are supported (See Table 5.1).

NOTE: Program the Measuring Units first because subsequent
menus may be based on the units selected. Once Flow Unit of
Measure is changed the Totalizer’s Volume based Unit of Measure
will be automatically changed.

,

5.3.4 “Submenu User-Defined Units”

In addition to conventional flow units user-defined flow engineering units may be
selected. Use the “Engineering Units and K-Factor Menu” to navigate to the
“User-defined Units” menu option. This option enables user-defined configura­tion of any engineering unit required for process measurement.

The following three parameters are available for this function:

a) UD Unit volume K-Factor (defined in Liters),
b) UD Unit time base (defined in Seconds),
c) UD Unit use density (units with or without density support).

Before using the User-defined Unit, be sure the proper conversion factor of the
new unit with respect to one liter is set (the default entry is 1.00 Liter). Also, prop­er time base values for User-Defined Units must be set.

set to “YES”. The default entry is “NO” so the Fluid STD Density parameter is not
used for flow rate calculation.

5.3.5 Submenu “K-Factors Settings”

Conversion factors relative to Nitrogen are convenient to use when the flow
meter/controller mated to the TIO is calibrated for Nitrogen and another gas is
required to be measured/controlled.

Conversion factors relative to Nitrogen for up to 22 common gases are stored in
the TIO (see APPENDIX II). In addition, provision is made for a user-defined con-
version factor. Conversion factors may be applied to all units of measure (except
%FS unit) via LCD/Keypad or digital communication interface.

The following three parameters are available for this function:

a) K-Factor Mode: Disable, Internal Index, user-defined (default Disabled)
b) Internal K Factor Index: 1 – 22 (from internal K-Factor table, see APPENDIX II)
c) User-defined K-Factor: 0.001 – 999.9 (default value is 1.000).

5.3.6 Submenu “Alarm Settings”

TIO provides the user with a flexible Alarm/warning system that monitors the Fluid
Flow for conditions that fall outside configurable limits as well as visual feedback
for the user via the LCD or via an optically-isolated output. The Flow Alarm has
several attributes which may be configured by the user via LCD/Keypad or digital
communication interface. These attributes control the conditions which cause the
Alarm to occur and to specify actions to be taken when the flow rate is outside the
specified conditions.

Depending on the TIO function configuration (flow meter or controller) there are
two Alarm algorithms. If the TIO is configured as a flow meter, Flow Alarm condi­tions become true when the current flow reading is equal to or Higher/Lower than
corresponding values of High and Low Flow Alarm levels. If TIO is configured as
flow controller, Flow Alarm conditions become true when difference between Set
Point value and current flow reading is equal or Higher/Lower than corresponding
values of High and Low Flow Alarm levels.

Alarm action can be assigned with preset Delay Interval (0-3600 seconds) to acti­vate the optically-isolated output (separate for High and Low Alarm). Latch Mode
control feature allows each optical output to be latched on or follow the corre­sponding Alarm status.

Following settings are available for Flow Alarm (see Figure 5.7):

Note: The conversion factors will not be applied for the % F.S.
engineering unit.

a) Flow Alarm Mode (Tabular entry)

This function determines whether the Flow Alarm is Enabled or Disabled.
The following selections are available: Enabled or Disabled. The default
entry is Disabled. Alarm Mode selections can be set with the UP and DN
buttons and are accepted by pressing ENT button.

b) Low Flow Alarm (Numerical entry)

The limit of required Low Flow Alarm value can be entered in increments
of 0.1% from 0 - 100%F.S.

If a Low Alarm occurs, and one of the two optical outputs is assigned to the Low Flow
Alarm Event (see paragraph 5.3.10) the optically-isolated output will be activated:

• For Flow Meter function: when the flow is less than the Low Flow
Alarm value.

• For Flow Controller function: when the absolute difference between
Set Point value and actual flow reading is equal to or higher than the
Low Flow Alarm value and Actual Flow value is less than Set Point
value.

The Low Flow Alarm condition is also indicated on the corresponding Process
Information Screen by displaying L character.

c) High Flow Alarm (Numerical entry)

The limit of required High Flow Alarm value can be entered in increments
of 0.1% from 0 - 100% F.S. If a High Alarm occurs, and one of the two
optical outputs is assigned to the High Flow Alarm Event (see paragraph

5.3.10) the optically-isolated output will be activated for:

• Flow Meter function: when the flow is more than the High Flow Alarm
value.

• Flow Controller function: when absolute difference between Set Point
value and Actual Flow reading is equal to or higher than the High Flow
Alarm value and actual flow value is more than set point value.

The High Flow Alarm condition is also indicated on the corresponding Process
Information Screen by displaying the H character.

NOTE: For Flow Meter function the value of the Low Flow Alarm must
be less than the value of the High Flow Alarm.
