then repeat the reset from “Reset Alarm

deterioration of the signal received due
to deposits on the front of the detector or
to misalignment beyond tolerance

checked with the “adjust” menu (if the
reading is below 50% then maintenance
is necessary). If the problem comes
back, check physical alignment of the

Read the signal received value using the
< Adjustment > menu. If the figure is
between 104% and 107% lower the
Transmitter level to 100%. If necessary
check the rigidity of the structure to
which the barrier is fastened or the
fastening itself.

environment is cleaner that when the
calibration was carried out, so the signal
received is greater with a consequent
saturation signal. In this case adjust the

<Adjustment> menu until you reach a
reading of 100%.
