TAC Xenta OP
Operator Panel
TAC Xenta OP is a small operator panel designed to be used with the TAC Xenta 100, 300 or 400 units. It has an LCD display with
4x20 characters and six push buttons.
TAC Xenta OP/RU can also display Cyrillic characters. TAC Xenta OP is connected via a modular jack situated on the rear of the unit.
Both communication and power supply are handled by this cable. TAC Xenta OP may also be connected directly to the network,
using the screw terminals.
The LCD display may be backlit.
The operator panel allows access to the parameters and makes it possible to list 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.
The operator panel can be placed on the TAC Xenta units, mounted on a cabinet front or used as a hand-held terminal.

Values can be read and/or altered from
the operator panel (see fig. 1). The operator panel can be mounted on the front
of the controller, on a cabinet front or
used as a hand held panel.
All values are displayed with explanatory
texts. Finding and altering a setting requires a minimum of key operations since
all values are arranged in logical order.
Authorization check
The system manager may choose to
use an access code to limit access to the
program.
List of contents
The TAC Xenta controller’s program functions are presented as a list of contents,
with the most common daily functions at
the top (see figure below).
The operator steps up and down in the
list by means of the arrow buttons.
IDs
(The top line of the list of contents
displays the current unit’s full ID together
with a short four letter ID which is shown
in all displays. To change object (AHU,
boiler etc.), press “Home” and select a
new object in the presented list.
To select and show a function
The function of the upper line in the list
of contents is shown when pressing the
“Enter” button. The displayed data are
dynamically updated.
To show the next/previous function, press
the arrow buttons. To return to the list of
contents just press the “Home” button.
To alter a value
The operator can move the cursor
between the alterable values with the
“Enter” button. The value can then be
increased, decreased or toggled by means
of the “+” or “–” buttons. The arrow
buttons are used to present the next/previous function.

Example:
When adjusting the week schedule, the
cursor can be moved between On time
(08:00), Off time (12:00), and Day IDs
(Monday, Tuesday etc.).
FUNCTIONS
Some examples of functions that are
available on the TAC Xenta OP:
- Select and display Groups and individual
Xenta controllers
- Display values and status indicators
INSTALLATION
The operator panel is either mounted
onto the TAC Xenta unit by means of the
snap-in connector, or flush-mounted in
the cabinet front or used as a hand-held
terminal.
When connecting the operator panel
there are two alternatives:
Use the modular jack on the front of
1.
the TAC Xenta and on the back of the
OP. This requires a special cable, for
both power supply and communication. Such a cable (about 1.5 m or
4.9 ft.) is included. If another cable
is used, its length should not exceed
10 m (33 ft.).
If the connection is done to the comms2.
line, use the screw terminals on the
back of the OP, labelled 1-4.
Terminals 1 and 2 are used for communication and terminals 3 and 4 for
24 V AC or DC.
The polarity is important only for the
DC connection.
– List and acknowledge alarms
– Set week charts and holidays
– Set date and time
If the correct access code has been
entered more functions are accessible, for
example:
– Modify control parameters
– Change access code
– Manual control
– Set daylight saving time
– Initiate supervisory system test dial-up
If no changes have been made within
5 minutes, the operator will be logged
off and the access level returned to the
default access level low.
