Be sure the connections have been correctly carried out and the voltage supply is the correct one.
Shield cable (
ACEFLEX type
) with 3 x 1 mm
2
minimum section must be used,
connecting the net to EARTH
for the detector as well as for the
Control Unit being the maximum length of 125 m and 250 m if the cable section is increased to 3 x 1.5 mm
2
. Check that the detector rule
connections numbered with 1-2-3 are connected to the correct place as shown
(
figure 1
)
.
If the system is not provided of 4-20mA input but has 0-5V or 0-10V CC voltage input, then a resistor must be connected to carry out the
conversion as shown (
figure 2
). Bear in mind it always must be installed in the receiver device, never in the detector.
Depending on the voltage supply of the detector it is recommended a certain resistance to obtain a proportional voltage to the measurement
range of the detector.

• It is recommended that the system or device alarm point to which the detector is connected, do not exceed the 20% L.E.L. (1.8V 250W
and 3.6V 500 W).
• Under no circunstances inmerse the detector in water or any other liquid.
• It is recommended to recalibrate the detector after 2 years of its installation.
• This detector has been designed to operate in atmospheres with values lower than 100% L.E.L. of the gas it is calibrated for and with
a normal oxygen presence.
