‘NORMAL MODE’
When the power supply is connected, the instrument:
• activates the ‘conguration digits’, and displays the code for the actual
input signal range (see section 5)
• activates the decimal point (ash), showing the actual output signal
range (see section 8.3)
• the instrument is in ‘normal mode’ of operation
HOW TO ACCESS THE ‘CONFIGURATION MODE’ AND THE ‘TOOLS’ MENU
With the instrument in ‘normal mode’ of operation, there is access to the
‘conguration mode’ and the ‘tools’ menu.
• to access the ‘conguration mode’, press the ‘SQ’ (<) key for 1 second
(see section 8.2)
• to access the ‘tools’ menu, press the ‘UP’ (5) key for 1 second (see
section 8.4)
‘ECO’ FUNCTION (‘CONFIGURATION DIGITS’ ARE AUTOMATICALLY
POWERED OFF)
If there is no interaction from the operator for 60 seconds, the instrument
powers off the ‘conguration digits’. The decimal point remains active
(ashing), indicating that the instrument is working correctly.
HOW TO POWER ON THE ‘CONFIGURATION DIGITS’
To power on the ‘conguration digits’, press one of the front keys ‘SQ’
(<) or ‘UP’ (5). This will power on the ‘conguration digits’, and activate
the ‘normal mode’ of operation.
8. Conguration system
CONFIGURATION SYSTEM
The isolated signal converters provide a fast and easy conguration
system, based on function codes. Conguration is done through an
internal key pad, accessible behind the front cover.
‘CONFIGURATION DIGITS’
The instrument provides two numerical leds, to inform about the actual
state of the instrument, active input and output signal ranges, and error
codes (see section 11).
CONFIGURATION KEYS
The conguration keys are located inside the instrument, behind the
removable front cover. To access the conguration keys, remove the
output signal terminal, and open the front cover (see section 7). The
instrument allows to block the key functions, by activating an access
code (‘password’ function) (see section 8.5).
8.1. ‘Normal mode’ of operation
HOW TO ACCESS THE ‘CONFIGURATION MODE’
With the instrument in ‘normal mode’ of operation (see section 8.1),
press for 1 second the ‘SQ’ (<) key. The horizontal leds lights from
bottom to top. When the upper led lights, the instrument activates the
‘conguration mode’.
If the key is released before activating the ‘conguration mode’,
the horizontal leds light downwards from top to bottom, and
the instrument returns to ‘normal mode’ of operation.
Inside the ‘conguration mode’ the decimal point is not active.
Inside the ‘conguration mode’, the ‘conguration digits’ display
the code of the active input signal range (see section 5). Press the ‘UP’
(5) key to increase the code.
• press once to increase the value in +1
• maintain the key pressed to automatically increase the value
When the desired code is reached, press the ‘SQ’ (<) key. The leds light
a round shape while new conguration is stored, and the instrument
returns to ‘normal mode’ of operation.
When exiting the ‘conguration mode’ without changes (‘rollback’
activation, selection of ‘inactive codes’, etc), the horizontal leds
light down from top to bottom, and the instrument returns to
‘normal mode’ of operation.
‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 30 seconds, the instrument
exits the ‘conguration mode’ and returns to ‘normal mode’ of operation,
discarding changes.
OUTPUT 4/20 mA AND 0/10 Vdc
Instruments can be congured for 4/20 mA or 0/10 Vdc output signal.
The congured output signal is identied with the active decimal point
at the ‘conguration digits’.
• active decimal point to the right, for 4/20 mA output
• active decimal point to the left, for 0/10 Vdc output
Table 4 | Decimal point indicates the active output signal
Output 0/10 Vdc

8.2. ‘Conguration mode’
8.3. Output 4/20 mA and 0/10 Vdc
HOW TO CONFIGURE THE OUTPUT SIGNAL TO 4/20 mA AND 0/10 Vdc
With the instrument in ‘normal mode’ of operation, press the ‘SQ’ (<)
key and the ‘UP’ (5) key at the same time. The horizontal leds lights
from bottom to top. When the upper led lights, the actual decimal point
position is displayed. After 1 second, the new decimal point position
activates. Release the two keys, and the leds light a round shape while
the new conguration is stored, and the instrument returns to ‘normal
mode’ of operation.
Connect the output terminals according to the output signal
congured (see section 6).
