Foundation Fieldbus Protocol
Your transmitter has been preconfigured at the factory to the settings shown in Appendix B.
Compare your needs to the factory configuration and note the changes to the configuration you
must make.
If the transmitter is not connected to a flowtube or IMTSIM, it is necessary to put a jumper wire
between terminals Coil 1 and Coil 2 and also to provide power to the transmitter.
This section describes the procedures to quick start the transmitter from the optional local
keypad/display. Note that after you quick start the transmitter from the local keypad, you should
use the fieldbus host to ensure that parameter values associated with the host are changed to agree
with those changed from the local keypad/display. Otherwise, mismatch errors occur when you
attempt to place the transmitter into Auto mode.
To make changes to the configuration using the local keypad/display, go to 1 TOP LEVEL/Setup
by pressing the Left arrow repeatedly until the display reads 1 TOP LEVEL. Then use the
Up/Down arrow keys to go to 1 TOP LEVEL/Setup. The procedure to change your
configuration is demonstrated by the following example:
Engineering units (EGUs) in GPM (factory default setting)
Forward direction of flow (Unidir positive – factory default setting)
Flow range 0 to 150 GPM
Flowmeter factor of 18.22 (refer to “Determining the Meter Factor” on page 18)
Note that the factory default engineering units is already configured as GPM, so no change is required. 2. Note that the factory Output mode is also already configured as UniDir positive, so no change in the direction is required. 3. You must enter your flow upper range value however. To do this: a. Go to Setup Level 2 by pressing the Right arrow key. Next move to 2 SETUP Outputs with the Down arrow key. Then move to 3 OUTPUTS Output Mode with the Right arrow key
b. Use the Down arrow key to go to 3 OUTPUTS Range Info and the Right arrow
key to go to FORWARD URV? {#####.#} GPM (Default {00100.0}).
c. Press the Shift + Change keys to enter Edit mode. You are asked Go Offline?
Reply Yes by pressing the Right arrow key. The display shows FORWARD URV?
[#####.#] GPM.
d. Use the Right/Left arrow keys to move the cursor under the digits you want to
change. Use the Up/Down arrow keys to change the digits to the desired values. In
the case of this example, continue this procedure until the display reads
[00150.0].
e. Using the Right arrow key, move the cursor under the right bracket and press the
key to enter the URV. The display reads FORWARD URV? {150.0} GPM.
f. Press the key again to move back to 3 OUTPUTS Range Info.
4. Lastly, you have to enter your flowmeter factor. To do this:
a. Use the Left arrow key to move to the Level 2 menu, 2 SETUP Outputs.
b. Press the Down arrow key six times to move to 2 SETUP Calibration and the
Right arrow key to move to the Level 3 menu, 3 CALIBRATION Meter Factor.
See FIgure A-5.
c. Use the Right arrow key to move to MFACTOR FORMAT? {###.######}. This
format can be changed, if necessary, to accommodate the meter factor.
d. Use the Right arrow key to move to METER FACTOR? {###.######} (Default
{012.000000}. Then press Shift + Change to enter Edit mode.
e. Use the Right/Left arrow keys to move the cursor under the digits you want to
change. Use the Up/Down arrow keys to change the digits to the desired values. In
the case of this example, continue this procedure until the display reads
[018.220000]. Use the Right arrow key to move the cursor out past the right
bracket to save the setting. The display then reads METER FACTOR?
{018.219998}. Note that in some cases, as with this example, a slightly different
value appears. The magnitude of this difference is insignificant.
NOTE
To determine the correct meter factor, refer to “Determining the Meter Factor” on
page 18.
f. Press the Right arrow key again. The display reads 3 CALIBRATION Meter
Factor.
5. Now that all changes have been made, press the Left arrow key until you are asked Go
On-Line? Reply Yes by pressing the Right arrow key. To display flow measurement,
press the Right arrow key once more.
! CAUTION
If you change the upper range value or engineering units in the Transducer Block with
the local display pushbuttons without making a corresponding change in the
corresponding Analog Input Blocks from a fieldbus host, a mismatch error occurs and
the Analog Input Block reverts to Out of Service mode.
Determining the Meter Factor
First find the “Cal Factor” or “IMT25 Cal Fact” on the flowtube data label.
If the flowtube data label has a “IMT25 Cal Fact.” listing, use that value as the “Meter Factor.”
If only a “Cal Factor” value is found on the flowtube data label, that value must be multiplied by
the appropriate factor from Table 2 to calculate the “Meter Factor.”
Operation from Keypad/Display Panel
For local operation, configuration, and calibration, all operator entries are made through a
5-button keypad and all data is presented on a 2-line x 16 character LCD display. The
keypad/display of the IMT25 Transmitter is shown in Figure 1. Information on various types of
display is shown in Figure .
Figure 1. IMT25 Magnetic Flow Transmitter — Keypad/Display
All required functions are accomplished by using the four arrow keys alone and in combination
with the Shift key. Table 4 explains the function of each key
Top Level Menu
The Top Level menu displays the following modes – Measurements, Status, Identity, Quick Start
(in FoxCom and HART transmitters), Test Mode, and Setup. You can switch from one to another
in sequence by using the Up/Down arrow keys. To enter the second level menu from a particular
top level screen, press the Right arrow key. To return to the top level from a second level menu
item, press the Left arrow key. The level of the first, second, third, and fourth level menus is
indicated by the digit appearing as the first character in Line 1 of the display; a 1 indicates Level 1
(Top Level), a 2 indicates Level 2, and a 3 indicates Level 3, etc.
The top level menu is shown in Figure 3. For a complete presentation of all menu structures, refer
to Appendix A.
Measurements Mode
The Measurements mode, which is your main operating mode, is displayed upon startup.
Depending on the transmitter configuration, it has up to seven displays, any of which may be set
as the startup default. All screens can be scrolled with the Up/Down arrow keys.
Rate (EGU) — Shows current flow rate (forward or reverse) in the selected
engineering units.
Rate (% Range) — Shows current flow rate (forward or reverse) as a percentage of full
scale URV.
Fwd Tot — Shows current value of the forward totalized flow in engineering units.
Use the Net Tot display to reset.
Rev Tot — Shows current value of the reverse totalized flow in engineering units. Use
the Net Tot display to reset.
Net Tot — Shows current value of the net totalized flow (forward total – reverse total)
in selected engineering units. Press Shift + Reset to reset the displayed total to
zero. Resetting Net Tot also resets Fwd Tot and Rev Tot. It does not reset Gr Tot.
If Reset Totals is passcode protected, the message Enter Passcode appears.
Grand Tot — Shows current value of the grand total flow in engineering units. Press
Shift + Reset to reset the displayed total to zero. Resetting Gr Tot does not reset
Fwd Tot, Rev Tot, and Net Tot. If Reset Totals is passcode protected, the message
Enter Passcode appears.
If the Dual Display feature is configured On, a combination of two of these parameters can be
displayed at once. A typical dual display, in which Line 1 shows flow rate and Line 2 shows the
present forward total, is shown below. Units may not be displayed or may be truncated.
You may step through the displays of each of these parameters with the Up and Down arrow keys.
However, unless you specifically do so, the display defaults to that configured in Setup mode. The
engineering units and formats used in the displays are also configured in Setup mode.
Status Mode
The Status mode enables you to view fourteen system parameters and thus assess the performance
of the loop. You may not edit them in this mode. To step through the displays of the following
parameters, use the up/down arrow keys:
Mode — Shows the present operating mode: On-Line, Off-Line, Override, or
Calibrate. This will normally display On-Line. The other modes will only be
displayed if someone else has changed the mode with an I/A Series Workstation,
PC-Based Configurator, HART Communicator, or fieldbus host. Off-Line means
that it has been taken off-line; Override, that the measurements cannot be relied
upon because one or more of the outputs is at a preset value; and Calibrate, that the
transmitter is in Calibration mode.
Alarm — Shows the most current active alarm. If there are no active alarms but
something is in the history buffer, the display reads Alarms In Buffer. If there are
no active alarms and nothing in the buffer, display reads No Alarms.
Diagnostics — Shows No Diag, Diag Existed, or Diag Exists. If a diagnostic
problem exists, the second line identifies the problem. Help is available with the
Shift + Help keys. An active diagnostic problem cannot be cleared; the problem
must be corrected. Diag Existed means a diagnostic error did occur, but the
condition has cleared and the transmitter is working correctly. However, the Diag icon
will remain on the display until the diagnostic has been acknowledged. To clear, the
transmitter must be in the Status mode with the diag window displayed. Then use the
Shift + Ack keys.
Digital Output — If the transmitter output is in Digital Output mode, the display
shows whether the transmitter is configured for Unidirectional or BiDirectional flow.
If the transmitter is not in Digital Output mode, the screen is not displayed.
NOTE
Digital and Analog Output are mutually exclusive. Only one of the two are displayed
at any one time.
Analog Output — If the transmitter output is in Analog Output mode, the display
shows whether the transmitter is configured for U (unidirectional), U/M1

GENERAL INFORMATION
OVERVIEW
This is a highly reliable dual channel vibration monitor which monitors the shaft vibration of
rotating machinery.
Both a 10-slot rack mounting type and a single-unit independent type with a built-in power supply
are available so that it can respond flexibly to any system design from medium and small scale
rotating machinery to TSI. The monitor accepts signals detected by a transducer and displays them
on LCD.
It is also possible to set ALERT and DANGER alarm levels independently to detect machine
failures early on and inform the operator of these failures. It has a built-in self-diagnostic function
to inform the operator of input transducer failures, thereby preventing rotating machinery from
false shutdowns.
FEATURES
• Conforms to API St’d 670
• The monitor is available as a single unit independent type or a rack mounting type.
• Has a self-diagnostic function.
• Allows the operator to change each setting even in the field.
• Important information such as measured value, alarm set value and gap voltage is normally
displayed.
• Can isolate recorder output (option).
