AUXILIARY ANALOG INPUT (LIN/TC)
The GFX4-IR has 4 inputs defined as auxiliary (IN5 for zone 1, IN6 for zone 2, IN7 for zone 3, IN8 for zone 4) to which
TC or linear temperature sensors can be connected.
The presence of these inputs is optional and, for model GFX4-IR-x-x-4-x-x is defined by the order code.
The input value, saved in variable In.2, can be read and used to activate the alarm signals assigned to it.
When an auxiliary input is present, you have to dene the following parameters:
- sensor type (AI.2);
- its function (tP.2);
- decimal point position (dP.2);
- scale limits (HS.2 – LS.2);
- offset correction value (oFS.2).
If the sensor is a thermocouple, the minimum and maximum limits can be dened in the specic scale of the sensor
used. The range of values settable for alarm setpoints depends on these limits.
There is also a digital lter (Flt.2) that can be used to reduce noise on the input signal.
