The pulse adapter is part of the INDIV-5 AMR
system. It acquires and processes the pulses from
one or two consumption meters with pulse
output and transmits the data to a readout
system.
The pulse adapter is equipped with an optical
interface for parameter setting.
Functions
• Acquisition of the pulses delivered by the
connected consumption meters.
• Monitoring of the connection cable in the case
of meters with NAMUR circuitry.
• Processing the pulses and storage of consumption data and due date values.
• Transmission of data via radio six times per day
to the network node of the INDIV-5 AMR
system.
Stored data
• Current consumption value.
• Due date value.
• Due date.
• 13 monthly values.
• Error code.
• Error date.
Parameter setting possibilities when using
the service software
• Due date.
• Meter count.
• Pulse generator medium.
• Device number.
Preset default parameters
• Due date 31.12.
• Meter count 0.00 m³.
• Medium cold water (channel 1), hot water
(channel 2).

During installation, the pulse adapter must be
programmed with the data record provided by
the parameter setting software for the meter to
be connected.
If meters are to be connected that are not
contained in the meter database, a new data
record must be requested from the local Danfoss
sales company.
With the correct data record, the following meter
types can be connected:
• Water meter with pulse output.
• Heat meter, heat/cold meter with pulse output.
• Gas meter with pulse output.
• Electricity meter with S0 interface (additional
pulse converter is required).

Power supply:The pulse adapter has a non-replaceable lithium battery as an energy source.
Display,
levels
The display has four display levels:
• Channel 1 (Ch1)
• Channel 2 (CH2)
• Statistics 1 (St1)
• Statistics 2 (St2)
The current display level is indicated by a small arrow (▲)
below the respective name of the level.
Pressing the button briey switches within a display level,
pressing the button longer switches from one display level to
the next.
The rst two display levels show current meter-related values.
The other two display levels show 13 end-of-the-month values
of the respective meter.
The display levels three and four (statistics 1 and statistics 2) are identical.
They show the consumption values and the date of this consumption for the past 13 months.

Alternates between consumption value and last day of the
previous month (notation: dd.mm.yy).
Alternates between consumption value and last day of the
month before last (notation: dd.mm.yy).
Displays continue for the last 13 months.
