Note .- The 2 relay outputs and the Optional Boards are

1.3- FRONTAL VIEW AND REAR VIEW

We strongly recommend you to read the following
paragraphs. Following ideas need to be clearly understood
in order to easily adjust and program the unit.

WHEN POWERING THE INSTRUMENT the meter displays
a message indicating the configured signal input range (see
page 4).

IF THE TAS-1 DETECTS A STRANGE SITUA TION on the
instrument status, or sensor break, etc, the instrument will
show an error message (see page 8 «messages and
errors»).

THE FRONTAL KEYPAD is composed of 5 function/key
pads and 1 programming pad. The pads have two functions,
acting both as number keys (when a number needs to be
entered) and as direct access keys to the following
functions :

Key AL - Access to the ALARM setpoints
Key HI - V alue for the HIGH Indication
Key LO - V alue for the LOWIndication
Key ADJ - Access to the automatic «on the

field» offset correction and High Level
Input Signal correction

Key DP - Decimal Point Position
Key PROG - Allows the introduction of the

PROGRAMMING codes (4 digit
codes, as shown on page 4). These
codes, when validated, activate
different input signal modes, and
advanced configurations for alarms,
indication, etc.

«TIME» MESSAGE .- If while introducing a programming
code or while reconfiguring the unit parameters (such as
the alarm setpoints or others) the user does not interact
with the unit for a period of 5 seconds, the TAS-1 will show
the message «TIME», cancel the ongoing changes, and
roll-back to the previous configuration. This is a security
function which disables the situation where a unit would be
«hanged» for a long time waiting for the operator to finish a
programming.

THE TAS-1 UNITS ARE FULL Y CONFIGURABLE. The unit
is 100% configurable from the frontal keypad. The
programming software also allows an easy configuration
from a PC (PCConnection Cable needed).

OPTIONS .- This manual includes description and operating
instructions for the basic unit and the additional extra
options accepted. These options include Relay Output
Contacts, Analog Outputs, RS485 Outputs, Peak/Valley
memory, etc. If your instrument does not include these
options, they can easily be added.

SIGNAL INPUT RANGES .- To work with an input signal
range not indicated in this manual, select the closest input
signal range accepted, and change the input/indication
parameters with the code 14 1 1 (see later in this manual).
For example, to configure a 0/60 mV input coming from a
10 Amper shunt, we need to :

1.- select the 0/100 mV input signal range

2.- enter on code 14 1 1 for Editing Adjustments

3.- edit 0=0 and 60=10.000

If later on we need to change the 10.000 value for any other
value we can do it directly with the keypad HI.

4.11-MESSAGES AND ERRORS

5- CONFIGURING WITH A PC

TAS-1 units allow configuration from a PC. You need software SW-TAS­1 and the cable PCConnector. Cable is connected to the rear side of the
instrument (stereo jack) and to the 9-pin SUB-D PC Port. Software installs
executable file TAS-1.exe

1.- Select com port. Press «START COMM»

2.- Configuration windows open

These windows contain all information on the unit. Meter and alarms are
shown on the main window. Additional options are shown in the small
window to the right.

To force a writing onto the device press WRITE_D. Some changes
already force a writing (such as changing the input signal), and ask for
a confirmation.

To force a configuration reading of the instrument press READ_D
To save/load configurations on your hard disk, use buttons SAVE_F /

READ_F. Note that the options (right windows) have their own
configuration file independent of the main instrument and so have their
own «SAVE T O FILE» / «LOAD FROM FILE» buttons.

Messages and errors are active when the instrument senses a «not
normal» situation . The instrument identifies the type of «anormality»
and informs with an error or with a message.

Messages

«Messages» are associated with non-critical situations, those
which only affect the measure temporary. The «message»
remains active on display until the situation clears. The
instrument recovers the normal working state when situation
clears.

Errors

«Errors» are associated with critical situtations which disable the
hability to measure the signal.

The «error» remains active on display until the situation disapears. At
this time, the instrument recovers normal functionality.

«Errors» execute actions on alarms, activating or deactivating them
depending on the status of variable OnErr (see page.11). Alarms
recover their normal behaviour when the the error state clears.

Internal Error. Restart the instrument.
** It is possible that no action is performed on alarms
if this error is affecting the internal EPROM

Mathematical Error 0
Parameters introduced for the input signal are not
coherent. (Typical case : the high level value is similar or
very close to low level value, on input signal range or
indication)

Mathematical Error 1: mathematical overflow.

The TSAT board adds analog output capabilities to the TAS-1
instruments. Jumper selectable for voltage ( 0/10 Vdc) and for
current (4/20mA and 0/20mA in modes SINK and SOURCE) adds
a galvanic isolation of 2KVef f.

The analog output adjustment is done via the frontal keypad. The
analog output value is adjusted related to the display indication.
This allows the intelligent use of the correction functions for offsets
and fast readjustment of the TAS-1 series, meaning that when

7.2- INST ALLING THE OPTION BOARDS

The Option Boards are inserted onto the vertical pins of the Expansion
Modules. These modules are AL2 or EXP.

Note .- Both AL2 and EXP are optional themselves and are not included in the
standard units

The board has to be firmly inserted onto the vertical pins of the expansion
module. Once inserted, reconnect the expansion module to the fron­tal of the instrument and insert the whole into the box.

The instrument automatically recognizes the pressence of an inserted
board.

Note1 : The expansion module is included with those instruments TAS-1 with the
AL2 option built in or the EXP option. The AL2 or the EXP modules can be also added
to those instruments who were acquired without any of these two options.

Note2 : The TEK board can share the expansion bus with the TSAT option of with
the R485M option, or can be directly connected to the bus alone.

Nota3 : Boards TSAT for Analog Output and R485M for Modbus output can not be
integrated simultaneously on the same instrument.

correct voltage and frequency. Do not use other power supply otherwise
permanent damage may be caused to the unit. Do not connect the unit to
power sources heavily loaded or to circuits which power loads in cycle ON­OFF or to circuits which power inductive loads.

WARNING.- On units with DC power supply, be careful with the polarity
indicated for each terminal.

SIGNAL WIRING.- Certain considerations must be given when installing the
signal input wires. Long wires can act like an antenna and introduce
electrical noise to the unit, therefore :

Do not install the signal input wires in the same conduct with power lines,
heaters, solenoids, SCR controls etc...and always far from these elements.

When shielded wires are used, leave unconnected the shield on the
indicator side and connect the other end of the shield to the ground terminal
of the machine.
