1000 litres / kWh / pulse without unit
Installation notes for the pulse inputs
It is important that the pulse cables not be affected by (or exposed to) the M-Bus voltage!
Check the polarity of pulse generators with ‘open collector’ outputs.
The cable wires must not touch each other during installation, otherwise pulses will be counted in the instrument.
When setting up the meter it may be necessary to adjust the meter reading of the instruments connected and the
pulse value using the ’Device Monitor’ software.

9.6 Potential-free pulse output (optional)
The potential-free pulse output is an electronic switch that outputs counting pulses of the meter which can be
used for any purpose.
The pulse output closes, corresponding to the pulse value shown on the type identification label on the
instrument.

10 Hint flags
When the instrument has detected a hint flag, the hint symbol is displayed:
The specific hint flag can be found at the menu item 8 ‘Hint flag’ in level 1 / Main loop (see section 7. Display). The
instrument recognizes seven hint causes, which can also occur in combination with each other. The flags are
shown on the display. The hint flag is displayed alternately in binary and hexadecimal form.
