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.

WARNING.
These measurement should be performed in
clean air.
Moreover, this test must be performed only with
the probe connected to a control unit, or with a
220 Ohm resistance installed between terminal 2
and terminal 3.
