Output pulses are output at these terminals depending on the change in the volume
flow rate. The pulse output factor can be used to weight the number of output pulses
in relation to the increase in volume.
For the device types TME400-VC and TME400-VCF, the dependence of the pulse
output on the standard volume can also be selected (see coordinates A11 and A21).
In coordinate A23 the possible pulse width can be 20ms, 125ms or 250ms.
A pressure sensor can be connected to the four connections of
terminal block X8
:
"+Up" positive and "-Up" negative voltage supply for pressure sensor; "RX" or "TX"
are the serial data received from the pressure sensor or sent to the pressure sensor.
The temperature sensor, a Pt1000, is connected to the terminals
of terminal block
X11
in two-wire connection. Pressure and temperature sensors are generally only in
use with the TME400-VS and TME400-VCF versions.
The terminals of the
terminal block X10
are connections for an optional module
which is not yet supported by the firmware.
Use the wire end ferrules for the connecting cable and route them in from below; a
seal holds the cable. To be able to pull a cable out again, press the small white
square (marked with the X) down using a small screwdriver (at the bottom in
Figure

and
Figure 5: Connection assignment of
the TME400
; top of the plug strip) in order to open the locking device. Hold down the
square and pull the cable out of the connector strip.
Some connection examples are given on the following pages.
