Sices GC315 User Manual

168 GC315xx and GC400xx Technical Manual
The controller can manage a high number of analogue inputs, also considering those acquired
from the expansion modules DIGRIN, DITHERM and DIVIT.
For each analogue input it is possible to set two thresholds on the acquired measure and each
threshold can activate an anomaly. These anomalies are generic, as the controller does not
know how they have to be managed. And does not have pre-defined alarm messages. They
will not be described in the next paragraphs as they would be repetitions on the same
description for each analogue input. They are described here instead, mentioning the
parameters for input 1.
The controller assigns the numeric codes from 305 to 432 to the generic anomalies related to
the analogue inputs (document [1] and [2] contain a table showing the code for each input.
The operator has first of all to configure the error message which will be displayed on the
controller when the anomaly is active. He has to use parameter P.4002, unique for the two
thresholds. The controller will add a starting writing to the configured message:
 “High value:” if the anomaly is activated when the measure is higher than the
threshold.
 “Low value:” if the anomaly is activated when the measure is lower than the threshold.
For each analogue input, six parameters are then available, to manage the thresholds, three
for each threshold (P.4003, P.4004 and P.4005 for the first threshold of the first analogic input;
P.4006, P.4007 and P.4008 for the second threshold of the first analogic input).
In addition to the threshold value (P.4003 or P.4006) and to the delay to be managed (P.4004
or P.4007), the operator must configure the operations related to the threshold (P.4005 or
P.4008). The parameter which configures the actions is bit managed (each bit
enables/disables a function related to the threshold). For the description of these paragraphs
see Errore. L'origine riferimento non è stata trovata..
Attention: setting the delay to “0”, the anomaly is not disabled.
NOTE: since you cannot define in advance neither which digital or ANALOGUE inputs (those
from the controller or from the additional modules) will be used, nor what function will they
perform, the list below refers, as an example, to the parameters of the first configurable input.
The symbol (*) or the indication “or equivalent for the other inputs” next to a parameter show
that the same varies according to the particular input configured.
We will use the words enabling and activation:
 “Enabling an anomaly” means having the minimum conditions necessary in order for
the controller to observe the cause.
 “Activation of an anomaly” means having the cause, after the happened enabling.
