Note the polarity when making the connection. The pulse outputs are placed on the module with the following
terminal numbering:
Open collector (OB)
Opto FET
Pulse output C:
Connection terminals 16-
17
Pulse output D:
Connection terminals 18-
19
The pulse outputs are configured as part of the calculator’s configuration number via the PP code. Upon receipt of
order, the PP code is configured to 95 by default (unless otherwise informed by the customer). Valid PP codes
appear from the table below. The default code 95 is marked in green. The PP code can be reconfigured by means of
METERTOOL HCW. See the technical description of METERTOOL HCW (5512-2097).

3.4.11.1
Pulse Transmitter/Divider
The calculator can be configured so that the pulse outputs serve as either Pulse Transmitter or Pulse Divider. If the
outputs must serve as Pulse Transmitter, the calculator’s PP code is configured to either 80 or 82. Regardless of
whether both outputs are connected or floating, the PP code 80 with Pulse Transmitter on both Out-C and Out-D
causes an increased power consumption. If the outputs must serve as Pulse Divider, the calculator's PP code is
configured to 83 with 22 ms pulse duration or PP code 73 with 5 ms pulse duration.
Pulse Transmitter/Divider can, among other things, be used for external leak protection and makes it possible to
connect an additional calculator to the same flow sensor and to external control systems that regulate according to
flow pulses, for example Siemens RVD 250 and Danfoss ECL 310, both of which can use the PP code 73 with 5 ms
pulse duration.
3.4.11.2
Pulse outputs for meter count registers
As previously described, the outputs are configured in pairs (C1/C2 and D1/D2), which means that it is possible to
transmit output from two of the following meter count registers on pulse output C1/C2 and pulse output D1/D2,
respectively:
•
E1 (Heat energy)
•
E3 (Cooling energy)
•
V1 (Volume)
