data line and no ID is needed.
- The Baseline parameter must be set according to the real installation
situation. The default is 30.
- In terms of the system, change LM sensor to the On position, if
Background Luminance Sensor LM21 is installed.
- In terms of the system, PWD Sensor must be switched on for normal
operation including auto-calibration. PWD Sensor should only and
exclusively be switched off, if auto-calibration is not allowed.
- Message type 1 is the standard LT31 message. If the PW data option
was ordered, message type 2 is configured by default. For details on
other messages and descriptions, see Chapter 5, Operation on page
145.
- The standard Interval of a message is 10 seconds. If connected to a
MIDASIV system, 15 seconds must be configured.
- For messages, the standard Port is data for communication with a host
system. To check the data message, the port can be temporarily
changed to Maintenance. If the optional DMX501 modem is installed,
the port has to be configured to module.
