6.1. Temperature sensor connection
- Connect the sensor S1 wires to terminals "1 and 2" and wires sensor S2 to terminals "3 and 4": the
polarity is not relevant.
- Length of the sensor cables can be increased by user himself to up to 200 meters, using a PP 2x24
AWG cable.
6.2. Recommendations of IEC60364 standard
a) Install overload protectors in the controller supply.
b) Install transient suppressors – suppressor filter RC – in the circuit to increase the service life of the
controller relay. See connection instructions of the filter on the previous page.
c) The sensor cables may be together, but not in the same conduit where the power supply of the
controller and/or of the loads passes through.
NEW CONNECTION SYSTEM (QUICK COUPLING):
FASTON and PUSH-IN FAST
CONNECTION:
- Hold the wire near its end and insert it into the
desired slot.
- If necessary, press the bottom to assist the
connection.
DISCONNECT:
- To disconnect the cord, press the bottom and
remove it.
NOTE:
- In the connectors 1 to 6 the maximum wire
diameter that can be used is 1,5mm².
- The wires must be tinned or use Rocket Pin
terminals with a maximum diameter of 0,75mm².
BOTTOM
WIRE INPUT
The wire should be picked
in 5 mm and tinned.
Terminal Rocket Pin.
7. FIXING PROCEDURE
a) Cutout the panel plate (Image V - item 13) where the controller will be fixed, with dimensions
X = 71±0,5 mm and Y = 29±0,5 mm;
b) Remove the side locks (Image VI - item 13): To do this, squeeze the elliptical central part (with the
Logo Full Gauge Controls) and move the latches back;
c) Pass the wires through the cutout of the plate (image VII - Item 13) and make the electrical installation
as described in item 6;
d) Insert the controller into the panel cutout, from the outside in;
e) Replace the latches and push then until they are pressed against the panel, securing the controller to
the housing (see arrow in Figure VI - item 13);
f) Adjust the parameters as described in item 9.
