The commissioning and operation of the NZM...-XMC-... measuring module
are described in the following.
3.1 Operating the NZM-XMC-TC-MB universal module
The Reset button can be used to start the device and pre-configure the
communication parameters.
•
Pressing the button for at least one second will restart the device.
•
In order to enable the preset communication parameters, disconnect the
device from the supply voltage, hold the Reset button down, connect
the supply voltage, and release the button. After five seconds, the
device will be running with the preset communication parameters.
3.2 LED indicators
The NZM...-XMC-... measuring module is provided with four LEDs:
•
Power On LED: Flashing means that the device is connected and
working properly.
•
Three LEDs L1, L2 and L3 indicate the following:
•
Continuously lit: Phase and voltage are correct
•
Fast flashing: No phase voltage present
•
Slow flashing: phase sequence error
3.2.1 Pulse Output
Pulse output is done via an NPN optoisolated transistor output.
3.3 Network operation
The device is designed for operation in solidly grounded Wye networks with
four cables.
