Test after replacing the sensor.
Reconnect the power, the probe starts blinking to the waiting time (Warm-up).
After waiting you can proceed to test the functioning inputting the sample gas.
WARNING !! From this moment on for all the duration of 24 hours of self-calibration, the probe must stay in
clean air without loss of GAS.
The probe continues to blink at a low frequency again for 24 hours to make sure that the probe do the auto
calibration.
Before performing this operation disconnect the power to the probe
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.
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 10,80 Vdc and lesser than 26,4 Vdc.
Check that the connector of the sensor is correctly inserted.
If it’s connected to control unit. 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.
Remark
.
If the probes are connected to the control units BX308 and BX316 the voltage at the terminals 2 and 3 must
be from a minimum of 0.6 to a maximum of 0.75 VDC
If othe r p rob le ms arise , a sp e cialise d and /or authorise d te chnician and /or the Distrib utor 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.
