2.3.4 PV CONTROL INPUT

• Connect the wires with the

polarity as shown

• Use always compensation cable

of the correct type for the ther-
mocouple used

• The shield, if present, must be

connected to a proper earth.

• If a 3 wires system is used, use

always cables of the same
diameter (1mm

min.)

(line 20

/lead maximum resis-

tance)

• When using a 2 wires system, use

always cables of the same diam-
eter (1,5mm

min.) and put a

jumper between terminals 5 and 6

A When the distance between the

controller and the sensor is 15
mt. using a cable of 1.5 mm

diameter, produces an error on
the measure of 1°C.
