TAC Xenta OP Handbook 1 Introduction
1 Introduction
1.1 TAC Xenta OP
TAC Xenta OP is a small operator panel designed to be used together
with TAC Xenta 100, 300, 401 and 901 units.
The operator panel gives the user access to parameters and alarms
without communicating with a central system. Additionally, it is used
to monitor status, adjust setpoints and time channels. All values are
displayed with an explanatory text in the alphanumeric display win-
dow.
Please note!
The TAC Xenta OP and the other products of the Xenta family must
not be used for any other purpose than that for which it was designed.
Installation and repair may only be performed by authorized person-
nel.

This chapter contains technical data on the TAC Xenta OP.
1.3 More information
TAC Xenta OP is also described or mentioned in the following
documents:
• the TAC Xenta OP Operator panel data sheet (C-98-05)
• the handbooks for the different TAC Xenta controller units
• the “TAC Menta User’s manual”
Stand-alone TAC Xenta 300/3000 controllers and I/O modules can be
commissioned by using the Service menu of TAC Xenta OP (which is
not the same as the local OP service menu). This procedure is de-
scribed in the TAC Xenta 300 and 401 Handbook.

2 Connection and Basic Functions
2.1 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, 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 dialogue messages and will direct the operator panel what
to show on the display. Thus the operator panel will act as a dumb
terminal.

2.3 Connecting toTAC Xenta 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 300 or 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, la-
belled 1–4. Terminals 1 and 2 are used for communication and
terminals 3 and 4 for 24 V AC (or DC).
At the controller you use the terminals C1, C2 and G, G0.

2.5 Local functions of the OP Service menu
For simple hardware check of the OP and for certain system param-
eters 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.

This will also happen if no key has been used during about 40 seconds.
Selecting the OP mode
10. OP mode In TAC Xenta networks the OP may work in one of two
communication modes:
- for communication with Base units, TAC Xenta 300 and 400
- for communication with TAC Xenta 100
Furthermore, the OP can be more or less mobile, depending on the
way the OP is connected to the network.
Please refer to the next section!

3 Dialogs withTAC Xenta 100
3.1 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 300 and 401 con-
trollers, the TAC Xenta OP has two different communication modes.
3.2 Connecting toTAC Xenta 100
Note! 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 (in stead of the
Base units, TAC Xenta 300 or 401):
Press enter to
access Xenta 100
Press the key to get the display
Connecting to
Xenta 100 ...
Check that the LED on the Wall Module will flash for some 10
seconds or that the red Service LED turns on and then off after a
couple of seconds, on the connected controller.
If contact is established without the LED flashing, Xenta OP has
connected to another node in the network. In this case disconnect
Xenta OP and then reconnect.
