encoder inputs
The LMS5xx PRO/Heavy Duty has two encoder inputs (IN3 and IN4) that can be
selected via software.
The encoder pulses can be used to influence the size of so-called dynamic fields, for
example for speed-dependent vehicle monitoring. A dynamic field changes its length
with the speed measured e.g. by encoders.

When stationary (V = 0 m/s), the evaluation field has the size of the configured basic
field. The size increases continuously with increasing speed until the largest field exten‐
sion is reached at maximum speed.
Digital outputs
The LMS5xx Lite has three digital outputs, the LMS5xx PRO/Heavy Duty six.
The outputs can be used as digital outputs to ground or as volt-free outputs

For the

setting, the sensor always signals

regardless
of whether the outputs are switched by the field evaluation application or by SOPAS ET
telegrams.

If the field evaluation application is being used to switch an output, the LMS5xx may
signal evaluation field breaches or contour breaches. In SOPAS ET, you can configure
which evaluation case affects which output.
External digital outputs
Up to 8 additional digital outputs can be controlled via a CAN extension module (part
no. 6038825 or 6041328). To use the additional outputs, the extension module must
be activated.

NOTE
For monitoring the extension module (heartbeat), module ID < 63 must be set.
Relay outputs
The LMS531 Lite has two relay inputs, the LMS531 PRO four. These can optionally
be configured to switch to HIGH or LOW when an object or person is detected in the
evaluation field.
