Operating Instructions
Data Logger PreLOG (15190)
7 Functions
7.1 Pulse
Registration
Integrated debouncing of the pulse signal of a reed contact •
Integrated precipitation correction of the recorded pulses, respectively linearisation of the precipitation signal •
of LAMBRECHT precipitation sensors
Pulse output (OC, not galv. isolated) for uncorrected transmission of the input signal. At a resolution factor
•
≥ 0.1* the length of the returned pulse is 125 ms. At a resolution factor < 0.1 the pulse length will be reduced
to 10 ms.
7.2 Recording
Recording of precipitation pulses with timestamp •
Recording of precipitation amount in selectable time intervals •
Recording of precipitation amount between retrievals •
Recording of precipitation amount since switch on of the device •
7.3 Alarm / Event Message
Event message at start of precipitation •
Event message at end of precipitation •
Event message at exceeding of a max. precipitation amount since last retrieval or message •
Event message at exceeding of a max. precipitation amount as moving sum of a speci fi ed period (with •
hysteresis)
Event message at exceeding of a max. precipitation intensity (with hysteresis)
•
7.4 Data Output
Recorded measured values (no zero values) •
Data retrieval of the recorded values with timestamp to a CSV fi le or MeteoWare Rain database with the
programs:
PreLOG-Commander (USB / GSM-Mode) ◦
MeteoWare Rain (USB / GSM- / GPRS-Mode) ◦
Operating data •
Battery status (OK / charge) •
Flash memory status (in % available space) •
Name of the data logger / identi fi cation •
Firmware version •
Precipitation amount since switch on of the device •
Precipitation amount since last retrieval •
GPRS error code •
Position in the command sequence of the error causing command •
* A resolution factor 0.1 means 1 pulse = 0.1 mm (precipitation per m

Connecting pulse output - Open Collector
(OC)
The PreLOG comes with an Open Collector output which
can be used to forward the recorded pulses for example to
a programmable logic controller (PLC). See also „Pin As-
signment M12 Connector, 8-Pin“.
Remark: The PreLOG ECO has no OC output.
