Alarm 1
Alarm output 1, which is NO relay contact.
15, 16
Power supply
Meter power supply connection. Range of supply voltages
supported by the meter depends on the ordering code. It
is required to check if the rated range of the meter
corresponds to the installation to which the meter will be
connected before installing the meter.
20...28
Alarms 2, 3, 4
(optional)
The alarm outputs 2, 3 and 4 use a relay with a switching
contact.
30...34
Analog output
Analog output. The output must be properly connected
according to the type of output selected in the
configuration (voltage or current): the terminals 30 and 31
for the current output or the terminals 32 and 33 for the
voltage output. It is not possible to use the voltage and
current outputs at the same time - the correct value in
accordance with the configuration, will be available only
for the selected output type.
35, 36
Binary output
Open collector binary output for future applications. The
output should be left unconnected.
8, 14, 29 NC
Unused terminals. Should be left unconnected.
The example of input signal connections to connect the sensors with PNP output (Fig. 6a)
and NPN output (Fig. 6b) is shown below.
In the example shown above, the sensor is supplied from the auxiliary power supply
output. Fig. 7 below shows an example of connecting an incremental encoder with PNP
outputs supplied from the auxiliary power supply output (Fig. 7a) and a system where the
encoder is supplied from an external power supply (Fig. 7b). In the second circuit, an
additional connected button is used to reset the pulse counter (position).
