WARNING
Before connecting to the mains power, ensure the voltage is correct. Carefully follow the instructions and the
connections according to Regulations in force, keeping in mind that the signal cables should be laid separate
from the power cables.
Electrical connections
Description and connecting probe SG850 for OXYGEN
Attention!!
The regulations described in this paragraph must performed be authorized and specialized technician are suceptibile to
compromise the safety of the survey.
If the device does not start up.
Check that the 12/24 Vdc power is present, and that positive and negative polarity has not been inverted.
If the Fault LED lights up.
If the fault signal reaches the control unit connected to the probe.
Check that the cables are connected according to the drawing, and that the wire isolation sheath has not been pinched.
Check the voltage at the terminals 1-2. It must be higher than 11Vdc and lesser than 25Vdc.
Check the voltage at the terminals 2-3. It must be from a minimum of 0.8 Vdc to a maximum of 1.1 Vdc
If other problems arise, the Distributor of BEINAT S.r.l. should be contacted directly.
