3 Connection and Basic Functions
3.1 Description
The TAC Xenta OP Operator panel has an LCD display with 4*20
characters and six push buttons. A modular socket or four screw terminals are used for communication and for connecting the power supply.
These connectors are placed on the rear. There is also a potentiometer
to adjust the contrast of the display, on the rear.
The OP has an LCD display that can be lighted from beneath. The light
is controlled from the OP Service menu (section 2.5).
The operator panel is used to monitor status and to adjust setpoints and
time channels. It also makes it possible to list the alarms without communicating with a central system.
The operator panel is controlled from a master, a TAC Xenta 100, 280,
300 or 401 controller. When you start using the operator panel, it will
send a message to the master telling it what button was pushed. The
master contains the dialog messages and will direct the operator panel
what to show on the display. Thus the operator panel will act as a dumb
terminal.

3.2 Connecting to TAC Xenta 100
Normally the TAC Xenta OP is connected to the modular jack on the
lower side of the Wall Module. In this way the Xenta OP will get power
supply from the TAC Xenta 100 unit.
Cable between controller and Operator panel: max. 10 m
The contrast of the display can be adjusted with the potentiometer on the
rear of the operator panel; please refer to the figure in the next section.
3.3 Connecting to TAC Xenta 280/300/401
Cable between controller and Operator panel: max. 10 m.
When connecting the operator panel there are two alternatives (please
refer to the adjacent figures):
• Use the modular socket on the front of the TAC Xenta 280/300/
401 controller and the corresponding socket on the back of the
operator panel. This requires a special cable.
• Use the screw terminals on the back of the operator panel,
labelled 1–4. Terminals 1 and 2 are used for communication and
terminals 3 and 4 for 24 V AC (or DC).

3.5 Local Functions of the OP Service Menu
For simple hardware check of the OP and for certain system parameters
there is a local Service menu in the operator panel. The OP functions are
quite independent of the other TAC Xenta units and only require that the
operator panel is connected to the network and that the panel has not
been set in the TAC Xenta 100 communication mode (see below).
The Service menu appears if both the keys and are pressed
for about three seconds simultaneously.

4.1 General
TAC Xenta OP can be used as a service and limited commissioning tool
for the TAC Xenta 100 Zone Controllers. These controllers use Network Variables of the LonWorks standard type (“SNVT”, Standard
Network Variable Type) for all data communication on the network. All
Network Variables, including the configuration parameters can be
accessed via the keypad and the LCD display.
In order to separate this general kind of communication from the dedicated communication used with TAC Xenta 280/300/401 controllers,
the TAC Xenta OP has two different communication modes.

• The very first time a TAC Xenta OP is connected to a Xenta network, the TAC Xenta 100 communication mode is, by default, in
the Off state.
Please refer to the end of chapter 2 for the necessary procedures
to change the communication mode.
• When this has been done, the operator is given a choice to access
TAC Xenta 100 (instead of the TAC Xenta 280/300/401).

5.1 The Menus
The menus of the operator panel and the order in which they are presented are designed by an application programmer, using the
TAC Menta design tool.
Thus, the menus shown below are only examples. The principles showing how to select among the menus and how to change the values are,
however, general.
Cyrillic characters
The TAC Xenta OP/RU model has the capability of displaying Cyrillic
characters.
The TAC Menta User’s manual describes how you switch the character
files of the OP.
24 hour clock vs. AM/PM clock
In those menus that allow time (clock) entries, like the Time Schedule,
the Holiday chart (Time channels) and the Daylight saving menus, you
may choose to present time with a 24 hour clock or with a 12 hour clock,
also called an AM/PM clock. The choice is made already during the
menu design phase in TAC Menta.
To translate between the two modes of display the following table can
be used.
24 hour clock AM/PM clock

06.00 06.00 AM
11.59 11.59 AM

When the AM/PM clock is used, the time in the OP menus are compressed to hhAmm and hhPmm for hh.mm AM and hh.mm PM respectively.
5.2 Find and Change a Setpoint
This example starts with the first screen showing all TAC Xenta 300/
401 controllers in the network and shows how to find and change the
supply air setpoint in “AH02 West”:

Changes will be effective as soon as is pressed.
5.3 View/Acknowledge Alarms
To make the operator aware of unacknowledged alarms in the alarm list
the abbreviated application/base unit name (“AH02” in our examples)
will flash. When the item “Alarms” has been found and selected with
Enter, a screen like the following will appear:
AH02 ALARMS: 6/6
P1
PUMP STOPPED
99-JAN-15 14:05 ON
On the top row there is an indication that this is alarm number six of six
in the list. To see the other alarms in the list use or .
The text ON in the above alarm example indicates that the alarm has
tripped but not been acknowledged.
A selected alarm is acknowledged when the operator presses
(Enter). The text ON will change to, for example, “ACK”.
Alarms which have tripped and then returned to normal state are indicated with OFF.
On the Operator panel, for each point at any given moment, at most one
of the three alternatives below can appear:

Transitions between these three states at moments in time t1, t2 etc., and
the disappearance from the list, may occur in the way shown in the diagram below.
The alarm list is sorted in chronological order with the oldest event displayed at the top. The alarm list is dimensioned to allow all points of
alarm to appear at the same time.
If a TAC Xenta controller is connected to a supervisory system like
TAC Vista, another indication may appear in the alarm list. An asterisk
(*) in front of the signal name means that the alarm is blocked, that is,
information about changes between alarm on and alarm off will not be
sent to TAC Vista.
The alarms will, however, be listed on the OP as usual.
The blocking request is set/removed from TAC Vista.

5.4 Change the Time Channels
The operating hours for a selected object can be adjusted by altering one
or more time channels. This can be done from the operator panel. The
number of week schedules available for a specific time schedule is
defined in the application program.
The following is an example of an object (AH02) controlled by three
different schedules. The object is active 08:00–12:00 and 13:00–17:00
on weekdays and 08:00–12:00 on Saturdays. The example shows how
to change operating hours on Saturdays to be 08:00–13:30.
Example:
Week schedule
Go to the week schedule for AH02.
AH02: Time schedule
1234567
08:00–12:00 MTWTF
13:00–17:00 MTWTF
To get to the next schedule controlling AH02 press once.
AH02: Time schedule
1234567
08:00–12:00 S
As the cursor is positioned under “08”, must be pressed twice to
move the cursor to “12”. Use and to change the off hour to
“13”. Press once and adjust the minutes.
Notes
• Starting with TAC Xenta System program v 3.4 this blocking
function has been changed. The alarm information will be sent to
TAC Vista, as any normal alarm, but it will not be displayed on
the OP.
• TAC Vista stores the alarm event in the historical log, even if
alarms of priority 0 are not displayed in the alarm list.

When finished, press after the last entry and then use to
return to the previous menu level.
Holiday chart
The week schedule can be modified by a Holiday chart which defines
conditions for certain dates, for example when Christmas Eve occurs on
a workday:
AH02: Holiday chart
1234567
14:00–17:00 MTWTF
**-12-24 : **-12-24
The asterisks (**) act as “wild card”, that is, the date will in this case be
valid each year.
Use and to change the time and date values. Use to
move the cursor between the fields. To obtain asterisks in the date
fields, toggle the month value past 12. To obtain asterisks for the year
value, you must toggle backward from the value 94.
When finished, press after the last entry and then use to
return to the previous menu level.
The Holiday chart is valid throughout the 24 hours.
Note, for example, the following case:
Week schedule says active 08:00-18:00
Holiday chart says active 00:00-00:01
The object will be active for the one minute only.
Special cases
If you want the time channel to be turned off for the whole day and night
and use the 24 hour clock, you indicate this by
00:00-00:00
and with the AM/PM clock (please refer to section 4.1)
12A00-12A00
If, instead, you want the time channel to be turned on for the whole day
and night and use the 24 hour clock, you indicate this by
00:00-24:00
and with the AM/PM clock
12A00-00P00

In the latter case the end time (24:00 respective 00P00) is a normally
’nonexistent’ time value.
5.5 Access Code
Every item that is displayed in a menu on the operator panel has an
access level, which can be low, medium or high. An item with low
access level will always be visible on the display of the operator panel.
To show items, with access level medium or high, a correct access code
has to be given. There is one code giving access to low and medium
level items and one to give access to all levels.
The default codes are
Medium level: 1111
High level: 2222
To change access level go to the following menu:
AH02: ACCESS CODE
CODE: 0000
Change code to
extend menu
Use to move the cursor between the digits and use and
to change their value. When finished, leave the menu with .
If the correct code has been entered, some more items will now be visible in the list, for example, “Edit Access code”.
5.6 Edit Access Code
To change the code that gives the operator access to the medium or high
level items, the access level code for the level to be changed must first
be entered as described above. Then go to the Edit Access Code screen:
A2: EDIT ACCESS CODE
EDIT CODE: 0000
Change code for
the active level (no.)
Use to move the cursor between the digits and use and
to change their value. When finished, press and leave the

menu with . As the access code is changed only the standard (low
level) items will be shown. To show the medium or high level menu
items the new access code has to be entered as described in the previous
example.
After the download of an application from TAC Menta, the access code
will revert to the default value.
5.7 Overriding Inputs/Outputs
For access code high, it is possible to override the input and output values in the Status displays of the OP.
For example, to override a digital output you must indicate “manual
override” in the field just in front of the displayed value:
A2: Fan status
SF_out _0
With the cursor in the position just to the left of the 0 value, use
or twice to toggle up the manual override indicator (
→).
Press to confirm and to move the cursor to the value itself. It is
now possible to change the value, a value that will override the value set
by the controller.
The override indicator will remain visible (for all access levels) until it
is reset to normal, automatic mode.
Network Variables (please refer to the TAC Menta User’s manual) can
also be overridden in this way.
5.8 Daylight Saving
TAC Xenta 280/300 has built-in support for the European standard daylight saving. However, the OP can be used to set other conditions.
To change the Daylight saving period, the following menu is used.
L2: DAYLIGHT SAVING
MODE: 1 HOURS: 1
FROM: MM:DD HH:MM
TO : MM:DD HH:MM

As long as MODE: is 1, the European standard changeover prevails
(one hour on the night before the last Sunday of March at 02:00 and
October at 03:00).
If MODE: is toggled to 2 the displayed (entered) values will govern the
changeover from/to the Daylight saving time.
MODE: equal to 0 means that there will be no change.
Press to move the cursor between the figures and use and
to change the values. When you are finished, press a last
time and leave the menu with .
If an AM/PM clock is used, the time is entered according to the instructions given in section 4.1
5.9 Log Off
If no changes have been made within 30 minutes, the operator will be
logged off and the access level returned to the default access level low.
Values that have been modified in the menu, but not “Entered”, will not
be saved at Log off.
+
–
Note
• During the first hour after the automatic changeover from daylight saving time (MODE:1, 03:00 to 02:00) you must not set the
time manually. Should this happen, the clock will once again
move back to 02:00 when the time reaches 03:00.
