1 General
HHT 275 is a compact, hand-held terminal for operating the TZID-C/TZID-C200 positio-
ner via an FSK modem (see Data Sheet 18-0.22 EN for ordering details) using the
HART®-Protocol. It provides a local operating option which adds up to direct local opera-
tion via the TZID-C/TZID-C200 front panel and remote configuration by using the appro-
priate configuration program on a PC.
2 Connection
Connect the communicator to the positioner using the cable with 4 mm plug delivered
with it. The connection is made in parallel to the positioner’s connection terminals. When
you are using a power supply with FSK bus connection, the communicator can also be
connected to the FSK bus.
Read and observe the general operating instructions for the HART®
Communicator.

The active (i.e. selected) item of a displayed menu is highlighted and marked with a right
arrow (->).
A down arrow to the left of the last menu item displayed indicates that the menu contains
further items which can be called up by pressing the key.
Pressing the key will call up the Hot Key Menu which provides the following option:

ID-C/TZID-C200 non-volatile memory takes place.

After power-on, the communicator performs a self-test. Then the communication to the
connected TZID-C/TZID-C200 is set up automatically, and the Online Menu seen below
is displayed:
The Online Menu provides five menu options:
•Serve/ Watch
for display of several operating parameters
•Settings
for setting the TZID-C/TZID-C200 parameters
•Diagnostics
at present only providing an option for resetting the stroke and travel counters
•Simulation
for simulating situations
•Information
for entering/displaying device information
There are two ways to select a menu. You can either enter the number of the menu item
via the alphanumeric keypad or mark the option with the key and then select it with the
key.
Pressing the or (HOME) key will return you to the main menu.
If the TZID-C/TZID-C200, with which you try to communicate via the HART®communi
-
cator has already been set locally to the Conf mode, the following message will pop up:
"Local configuration is active occurred reading ... value. Press OK."
In this case it is not possible to configure the positioner via the communicator. If you
should ignore the message and nevertheless try to transmit data, the following message
is shown:
"Access restricted".
If you try to read parameters from the TZID-C/TZID-C200 which are currently being
modified locally, the input values are shown, even if they have not yet been confirmed
and stored in the TZID-C/TZID-C200 EEPROM. It is recommended to cancel communi-
cation from the communicator and retry at a later time.

3 Alarm, S1 and S2
Select the alarm and switching outputs according to the following table:
10 Digital input
The digital input defines six functions in the TZID-C/TZID-C200 positioner that
can be selected locally. If, for example, locks are activated, the positioner only
works in the selected operating mode when a voltage < 12 V is applied to the dig-
ital input. Please refer to the manual for the TZID-C positioner (42/18-64 EN) or
for the TZID-C200 positioner, respectively (42/18-73 EN) for a detailed descrip-
tion of the digital input functions.
AlarmOn=active low OFF = alarm output HIGH active
ON = alarm output LOW active
S_1ON=active low OFF = switching point 1 HIGH active
ON = switching point 1 LOW active
S_2ON=active low OFF = switching point 2 HIGH active
ON = switching point 2 LOW active
S1ON=act below Off =switching output 1 active when exceeded
ON =switching output 1 active when below
S2ON=act below Off =switching output 2 active when exceeded
ON =switching output 2 active when below

1 Min valve range
Enter the low valve range limit as a percentage of the lever range.
2 Max valve range
Enter the high valve range limit as a percentage of the lever range.
2 Digital setpoint
1 Setpoint mode
This item is used to define the setpoint (analog or digital) to be used by the
positioner. When the "Analog setp mode" option is selected, the positioner
will use the analog setpoint derived from the input current. When selecting
"Digital setp mode", the setpoint will be given exernally using the HART-Pro-
tocol. Note that the "Travel setpoint" has to be defined for the "Digital setp.
mode" (see next item.
2 Travel setpoint
This item is used to define the digital setpoint as a percentage. Note that this
setting can only be activated when the TZID-C/TZID-C200 is currently work-
ing in mode 1.0 or 1.1. Otherwise, an error message pops up.
3 Lever zero position
The lever zero position can be displayed/edited with this menu item. Options:

Options:
- Actuator turning counterclockwise
- Actuator turning clockwise
(seen from the front with the case open)
