1.7 Two potential-free pulse outputs (optional)
The potential-free pulse outputs provide counting pulses of the meter.
The pulse outputs close corresponding to the pulse value, see items „pulse value pulse output
1“ and „pulse value pulse output 2“ in display loop “6” (module loop).
Pulse outputs for energy:
The pulse value for energy is always determined by
the last place
of the energy display.
Examples:
Display: 0 kWh
-> pulse value: 1 kWh/pulse
Display: 0,000 MWh
-> pulse value: 0,001 MWh/pulse
Display: 0,000 GJ -> pulse value: 0,001 GJ/pulse
Pulse outputs for volume:
The pulse value for volume is always determined by
the second-to-last place
of the volume display.
Example:
Display: 0,000 m³ -> pulse value: 10 l/pulse (0,01 m³/pulse)

Retrofitting with an Additional Communication Interface
During installation of the retrofitting module observe the ESD requirements according to EN 61340-5-1.
This means that on location an antistatic wrist strap with an integrated 1 MΩ resistor has to be used which must be connected
to a proper spot: This is either a grounded pipe or – only with an appropriate adapter! – a Schuko plug grounding socket. The
antistatic wrist strap must be worn tightly on the skin of the wrist.
