4. INSTALLATION AND WIRING
During the installation, the following instructions must be considered:
Depending on the thermal characteristics of the measured material the sensor must be installed proper distance from the silo wall,
Depending on the cross section of the silo several sensors should be installed,
If the measured medium is granular solids, check the structural data of the silo's roof, and if necessary, stress needs to be relieved from the structure.
The place of installation must be selected so that it provides adequate space and easy access for installation, calibration and monitoring.
The instruments can be equipped with a flange or a threaded process connection according.
The housing of the instrument can be rotated. After the installation, turn the housing to the best position for easy reading.
4.1. WIRING
The transmitter is designed to operate in 2-wire systems with 11…36 V DC
power supply voltage.
The internal resistance of the devices between the transmitter and the power
supply unit depends on the power supply's voltage.
The wiring must be shielded.
The terminal screws can be accessed after removing the housing cover and
the display module (if there is one).
The unit must be grounded by its grounding screw.
The unit must be connected via the #3(–) and #4(+) terminals.
Programming can be performed after the device is powered on.
After wiring and programming the device, make sure to close the cover and
check if it seals properly.
The instrument may be damaged by electrostatic discharge (ESD) via its terminals; therefore, apply the precautions commonly used to avoid
electrostatic discharge, e. g., touch a properly grounded point before removing the cover of the enclosure.

5. COMMISSIONING AND PROGRAMMING
TM−, TJ− instruments can be adjusted and programmed with the SAP−300 display unit.
Without the SAP−300m, the following LED signs are possible:
VALID Indicates the readiness of the unit. If it is continuously on, the input signal is stabilized.
If it is blinking, the input signal is changing.
COM Indicates digital (HART) communication. During remote programming, the LED is continuously on.
When the SAP−300 display is present, it covers the LEDs; their functions are taken over by the display. In its default state, the
SAP display shows the table of the measured temperature values (see chapter 5.1).
Programming is supported by a text-based menu. Navigation is done by using the
E
/ / / buttons.
The instrument can operate without the SAP-300 module as well. Programming can be done only by using SAP−300 display
module locally or by HART (REMOTE PROGRAMMING) communication system remotely.
The SAP−300 is a 64x128 dot-matrix LCD display, which can be plugged into the transmitter. (The unit is universal, it can be used
in other NIVELCO devices, provided that the system software supports SAP−300.)
Warning!
The SAP−300 module is based on LCD technology! Make sure it is not exposed to continuous heat or direct sunlight to avoid
damaging the unit. If the instrument cannot be protected against direct sunlight or temperatures that are beyond the standard
operating temperature range of the SAP−300, remove the SAP display in the instrument.

14 / 28  tmh5554a0600p_06  tmh555en2106p
5.1. DISPLAYING MEASUREMENTS WITH THE SAP−300 DISPLAY MODULE
Legend:
1. Measured temperature values. From top to bottom, from left to right in increasing order. The instrument can
handle up to 15 sensors. The six horizontal lines indicate the absence of the sensor or a sensor error. The #1
sensor is the closest to the electronic housing; the following sensors are marked with a number in increasing order.
The last number belongs to the sensor at the bottom. The current measured temperature value appears inverted
on the display. The displayed inverse temperature value is refreshed on the display once every second.
2. Simulation. When the simulation sign is displayed, the output shows the values of the simulation and not the
actual measured values.
3. Unit of the measured values.
4. Menu Lock. If the key symbol is visible, the unit is protected with a password. When entering the menu, the
instrument asks for the password. If the REM message is shown, the instrument is in remote programming mode,
and the menu cannot be accessed.
5. Source of transmitted PV (Primary Value) (see 5.3.1.1.)
PV is the average of the measured temperature values.
PV is the maximal value of the measured temperature values. The number of the first sensor measuring the maximum temperature is in the
8th cell between brackets.
PV is the minimal value of the measured temperature values. The number of the first sensor measuring the minimum temperature is in the
8th cell between brackets.
PV is the measured temperature value of a particular sensor. The number of the selected sensor is between the <> marks.
6. The calculated value of the output current. After the unit, the inverted sign shows the current output mode:
Manual mode (see 5.3.2.1.)
Analog transmission; reacts to a programmed failure condition if an upper or lower fault current is programmed (see 0)
HART address, which is not 0, so 4 mA overwrites the output current (see 5.3.3)
Any errors during measurement are shown in the lower part of the display.
7. The average of measured values.
8. The maximum of the measured values and place (first occurrence) of the maximal value.

tmh5554a0600p_06  tmh555en2106p  15 / 28
Information screens
Press the button to cycle between information screens.
1. General information (DEV. INFO): overall running time (OV. RUN TIME), uptime since power on (RUN TIME),
type of interface (INTERFACE).
2. Sensor information: number of temperature sensors in the probe (TOTAL SENSOR COUNT), number of the
sensor with the highest number (RANGE).
3. HART communication information: short address, manufacturer ID, device type code, Rx-Tx message
counters – for debugging.
Information screens switch back to the main screen after 30 seconds.
Press the button to get back to the main screen at any time.
Press the
E
button on any of the screens to open the menu. Exiting the menu will always invoke the main screen.

16 / 28  tmh5554a0600p_06  tmh555en2106p
5.2. PROGRAMMING WITH THE SAP−300 DISPLAY MODULE
When entering the menu, the device copies the current parameter set, and all changes are made in this duplicate. The instrument keeps measuring and transmitting
values in accordance with the current (and intact) parameter set while programming. After exiting the menu, the instrument replaces the original parameters with the
new parameter set and starts measuring in accordance with the new parameters. This means that pressing the E button after changing the parameters does not
immediately make the new parameters effective!
Pressing the
E
button to enter the menu. Press the
E
button to exit the menu.
If the device is left in programming mode, it will automatically return to measuring mode, and all changes will be unsaved after 30 minutes. If the SAP−300 is
removed, the instrument will immediately exit from the menu, and all changes will be discarded.
Programming the device with the SAP−300 (manual programming) and HART (remote mode) at the same time is not possible. However, the measured values can be
read through HART at any time.
5.2.1 Components of the programming interface
The parameters of the instrument are grouped by their functions. The programming interface consists of lists, dialog windows, editing and report windows.
Lists
Navigate between the lines of lists by pressing the / buttons. Pressing the
E
button activates the list item under the
cursor. The cursor is the inverted line under which the items are cycled. Exit from a list by pressing the button.
Menu list
The menu list is a special list. Its characteristic is that upon selecting an item will invoke a sub-list. The menu header (1)
helps navigate the menu.
Enter the menu by pressing the E button. Navigate between the menu items by pressing the / buttons. Enter
E
to the
selected menu by pressing the E button. The selected list item is marked with inverse color.
Exit from a sub-menu with the button. Press the button in the main menu to exit programming mode, and the
instrument will return to measuring mode.
Dialog window
The system sends messages or warnings using dialog windows. They can usually be acknowledged by pressing the
button, or the choice between two options is offered, usually YES ( button) and NO ( button). In some cases, a
parameter has to be changed to correct an error!

tmh5554a0600p_06  tmh555en2106p  17 / 28
Edit windows
Edit windows are used for modifying numeric parameter values. The selected character can be changed using the /
buttons. The cursor can be moved to the left using the button.
The direction of the cursor movement through the digits is right to left and the items wrap around. Changed values can be
validated by pressing the E button. The software checks if the entered value is valid; exiting the edit window is only
possible if the entered value is valid. If the entered value cannot be interpreted, the software sends an error message in
the bottom line (1) of the display.
Edit windows – button combinations
The following button combinations are available in the edit window:
1. Reverting the parameters to the previously saved value ( + , pressed for 3 secs.).
2. Restoring default parameters ( + , pressed for 3 secs.).
3. Inserting the currently measured value to the edit window ( + , pressed for 3 secs.).
Only for certain parameters!

The values entered here must be between 3.9 and 20.5. The output current will take the entered value and analogue transmission will
be suspended. The set (current) value overrides the 4 mA output of HART multidrop mode. (See 5.3.2.1)
5.3.3 Digital output
HART short address
Parameter: P19
Menu path: OUTPUT SETUP / SERIAL OUTPUT / ADDRESS Default value: 01
Description: HART short address
The short address can be set between 0 and 15. If there is only one device, the short address can be 0, and this case the device
transmits 4…20 mA on its output. In Multidrop (if there is more than one device) mode, the short address must be other than zero, and
the output current is fixed at 4 mA. The fixed 4 mA output can be overridden as described in chapter 5.3.2.5.

5.3.4 Service functions
5.3.4.1 Security codes
User security code
Parameter: --
Menu path: SERVICE / SECURITY / USER LOCK
Description: Setting or unlocking the user security code.
The device can be protected against unauthorized programming with a 4-digit PIN code. If either of the digits differs from 0 the code is
active. If zero is specified, the secret code will be deleted!
If the code is active, it will have to be entered when entering the menu.
Service code
Parameter: --
Menu path: SERVICE / SECURITY / SERVICE LOCK
Description: Setting the service code (for trained personnel only!)
5.3.4.2 Loop current test
Parameter: P80
Menu path: SERVICE / OUTPUT TEST / ANALOG OUTPUT
Description: Loop current test (mA)
When editing this parameter, the currently measured value will be shown on the display and sent to the output. In test mode, values
between 3.9 and 20.5 mA can be entered into this parameter. The output current will be set to the entered value. The current
measured on the output must be equal to the set value.
In test mode, a dialog window will appear about the fixed output current until it is dismissed by pressing the
E
button.
