The installation of this rail-mounted device (9 HP, horizontal pitches) is envisaged in
distributor systems with common 35mm mounting rails (DIN rail) and covers with a 45mm
cut-out measurements. The wiring is connected via jack terminals in the lower and upper
device section (see
Figure 1
).
The Data logger is powered by an external 12V accumulator and can therefore work
independently from the mains. The accumulator is not part of the scope of supply.
It is also possible to power the logger with 24V AC/DC by means of a mains adapter.
A solar panel can be connected via separate terminals.
An integrated power management, fed by the solar input or the input for
24V AC/DC, charges the external 12V accumulator.
When the accumulator is disconnected, the clock is buffered by several hours with a buffer
capacitor.
Operation is guaranteed in a wide temperature range from -20° to 70°C.
The device can be simply operated by means of touch control directly on the display or via
the interfaces micro USB, Ethernet, COM1 and COM2. A colour LCD with 320 x 240 pixels
acts as a display.
The scanning of the measured values is configurable in the range from one second to 60
minutes. Pulses and frequencies are measured continuously.
The data is saved with time and date in accordance with the configured memory cycle (1s to
60 minutes) in a non-volatile Flash data store (64MB) (i.e. the data is retained even without
supply). The data store is designed as a so-called ring memory. Once the ring memory is full,
the oldest data set is always the next to be overwritten.
For the checking of the sensors or the measurement inputs, the Data logger can be switched
into the maintenance mode. In this mode, the sensor measured values do not go into the
memory. I.e. values determined during the maintenance mode are shown in the display as
usual, but are not taken into account for the calculation of memory values.
The data and/or measured values can be read out with the optional PC programme “Mevis”.
Note
The following DLL versions are necessary for the compatibility with the PC programme
“Mevis”:
DL16 Archive Reader DLL Version V1.17.0.0
DL16 FTP DLL Version V5.29.0.0
Note
The data logger can record a maximum of 100 measured values (channels)! Variables
derived from a measured value are also channels.
