analogue Sensors (only available if this option is set in Engineer mode)
A read-only display of analogue sensor settings, as described below:
Settings are shown in the format:
abc d.d C or B
The meaning of the numbers is as follows:
a = emitter current value (0 - 9).
b = receiver pot setting value (0- 9). Both ‘a’ & ‘b’ are mostly of use
only to Technical Support for fault checking in combination with other
parameters.
c = threshold voltage value (0 - 9). Should be approx. 4/5
If the values differ substantially from those shown above, the sensor is suspect.
d.dd = receiver voltage in volts. If clear, should be approx.
0.5v. If blocked, should be > 4v.
C / B = clear or blocked
Note: depending upon unit fitted, some sensors may show receiver voltage only, and
whether clear or blocked.
These figures are read-only – prior to analysing them, sensors should be auto-calibrated
and if any sensor fails, it should first be cleaned and its connector checked. Re-calibrate,
and then if failure still occurs it must be replaced by a Service Engineer. The figures may
help in fault finding if failure still occurs - contact Technical Support for further assistance.
