6.6 Access code 7 - Setting the address of the peripherals
The Access Code is accepted if the ENTER key is kept pressed when the Control Module is turned
on or by first typing Access Code 123.
For couplings with boards 9010/20 LCD version 2, set the baud rate at 9600 [see Table Cv16]. To
be performed only if the serial output RS485 is used.
6.7 Access code 52 - Initialisation operations
The Access Code is accepted if the ENTER button is kept pressed when the Control Unit is turned
on, or first typing the Access Code 123.
P21 Reducing the setting of places after the decimal.
The decimal places are referred to the display of the concentra-
tion
The decimal places
depend on the full
scale.
P22 Configuration for output failure manual reset [1M] Default is automatic
selective reset per
channel
P23 Regulation of 4 mA analogue output - use Up and
Down buttons
P24 Regulation of 20 mA analogue output - use Up and
Down buttons
Step Function NOTES
Step Function NOTES
P1 Setting the address of peripherals
Can be set from 0 to 255
Address common to
channel A and B
P2 Setting the zone
Can be set from 1 to 60
Individual for each
channel
P3 Redundancy RS 485: A [enabled], nA [disabled] Common to the
board
Step Function NOTES
P1 Setting of the presence of the relays or the opto-isolators
1 = Relay
2 = Opto-isolators
[Common for both of
the channels]
P2 Setting the type of power supply of the sensor related to the se-
lected channel
1 = Constant current
2 = Constant voltage
P3 Setting the type of input signal related to the selected channel
1 = Analogue with input in mV
2 = Analogue with input 420 mA equivalent from 0 to 100 % of
the full scale for two-wire transmitters
3 = Analogue with input 420 mA equivalent from 0 to 100 % of
the full scale for three-wire transmitters
ATTENTION: In the
ATEX version, when
passing from a 2 or 3
setting to 1, it is nec-
essary to check in
Access Code 4 P4
that the Unit of
Measure is Lel or
LEL/m.
