Remove the detector cover
Set the DIP switches
The DLO1191 can be operated either on an interactive DS11 line or a collective line. The
choice between collective and interactive line is made with DIP switch [S4].
The detector has 3 sensitivity settings («Reduced», «Standard», «Increased»). The re-
sponse threshold is set with DIP switch [S1], [S2].
The transmitter intensity (strong, weak) can be set with DIP switch [S3].
The DIP switch [S3] which governs the transmitter intensity is set to «strong» by default. If
the signal amplitude is too high (display on the adjustment unit: Range = 13, signal > 50),
the transmitter can be set to «weak». If the measurement section is ≤10m, a supplemen-
tary filter must be installed.
