Programming of the MMT and IIG4-N technological devices on
the control units
AM-2000; AM-4000; AM-6000
The AM series control unit through the LCD-6000T panel manages the new series of 4-20mA MMT and
IIG4-N modules.
All anomaly, pre-alarm and alarm signallings coming from 4-20mA devices will be managed only by the
LCD-6000T panel
These new devices occupy just one address for device on the analogue line.
Starting the self-programming procedure on the AM series control units the IIG4-Nmodules and the MMT
modules connected to the lines are recognized as sensors and the type id “Tec3” is assigned by default.
In fact, there are two types of type-Id for “TEC3” and “TEC2” technological devices.
The operating feature of the type-id “TEC3” is the following:
A pre-alarm threshold (P1) programmable by the user (default P1 = 10 % of the selected highest
value of the scale)
A pre-alarm threshold (P2) programmable by the user (default P2 = 20% of the selected highest
value of the scale)
An alarm threshold (AL) programmable by the user (default AL = 30% of the selected highest
value of the scale).
Highest value of the scale (refer to chapter
Technological Ranges
).
CBE
equation which is activated when the value detected by the device is higher than one the
three thresholds
(CBE active = OR (P1 P2 AL)). This CBE is used to activate any direct group.
Moreover you can activate an output module when on the 4-20mA device the threshold “
P1”
=
(A)
has been reached by simply writing, in the CBE equation of the output module, the following
function:
Possibility to activate an output module when, on the 4-20mA device, the “
P2”
=
(B)
threshold has been
reached by simply writing, in the CBE equation of the output module, the following function:
Possibility to activate an output module when on the 4-20mA device “
AL”= (C)
threshold has been reached
by simply writing, in the CBE equation of the output module, the following function.
