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).
Heat meter
Pulse output 1 heat energy
Pulse output 2 volume
Pulse outputs for energy:
The pulse value for energy is always determined by the last place of the energy display.
Examples:
Display: 0 kWh
Display: 0,000 MWh
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)

2 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.
2.1 Retrofitting PolluStat with an additional communication interface (optional)
We also offer a retrofittable meter to which communication interfaces can be added later.
To retrofit such a meter with an additional communication interface the calculator´s adhesive seal has to be destroyed and the
device´s calculator to be opened. Use a screwdriver with a wide tip (4 - 5 mm) and carefully press in the two round
predetermined breaking points above the cable feedthroughs (see picture 1).
