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 SITUATION 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
-
Value for the HIGH Indication
Key LO
-
Value for the LOWIndication
Key ADJ
-
Access to the automatic «on the
field» offset correction and High Level
Input Signal correction
Key DP

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 FULLY 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 11 (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 11 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.
