Resetting an output
By default the outputs are reset immediately to the inactive state. You can configure a delay
of up to 10 s (e.g. to activate a horn or to send the output signal to a PLC).
Alternatively you can also reset the output using an input. The output is reset only when the
allocated input has the configured status.
3.11 Inputs and outputs
3.11.1 Digital switching inputs
The LMS5xx Lite has two, the LMS5xx PRO/Heavy Duty has four digital switching inputs.
These inputs can activate different evaluation cases (see section 3.10.1 “Evaluation cases”
on page 40). With the aid of the inputs, the outputs on the LMS5xx can also be reset (see
section “Resetting an output” on page 44).
On the LMS5xx Lite only IN1 can be used for activating evaluation cases.
3.11.2 Encoder inputs
The LMS5xx PRO/Heavy Duty has two encoder inputs (IN3 and IN4) which can be selected
via software.
With the aid of the encoder pulses, the size of so-called dynamic fields can be changed, e.g.,
for speed-dependent vehicle monitoring. The length of a dynamic field changes with the
speed measured, e.g. using an encoder.

When stationary (V = 0 m/s) the evaluation field is the same size as the basic field
configured. The size increases continuously with increasing speed up to the largest physical
size for the field at the maximum speed.
3.11.3 Digital switching outputs
The LMS5xx Lite has three, the LMS5xx PRO/Heavy Duty has six digital switching outputs.
The outputs can be used as digital switching outputs to ground or as floating outputs (see
section 6.5.5 “Wiring of inputs and outputs on the LMS5xx” on page 82).
The sensor will always show Device Ready, no matter whether the outputs are switched by
the field evaluation application or by the SOPAS ET telegrams.

If an output is switched by the field evaluation application, the LMS5xx can signal evaluation
field infringements or contour infringements. For this purpose, configure in SOPAS ET which
evaluation case is to act on which output.
3.11.4 Relay outputs
The LMS531 Lite has two, the LMS531 PRO has four relay output. The outputs can be
configured to switch either to High or to Low if an object or a person is detected inside the
monitored field.
