Interfaces of the electronic unit
The UH50 heat meters are equipped with an optical
interface per EN 62056-21:2002 as standard.
Moreover, up to two of the following communication
modules can be used for remote reading (for
restrictions, see Page 5):
•
Pulse module (pulses for quantity of heat /
volume / unit status / tariff register 1 / tariff
register 2; isolated, bounce-free)
•
CL module (passive 20 mA current loop per EN
62056-21:2002)
•
M-bus module per EN 1434-3, fixed and
extended, variable protocol (also for coupling
with a suitable heating controller)
•
Analog
module
•
Radio
module
•
Multi-module
(external)
These modules are have no effect on consumption
metering and can therefore also be replaced at any
time without violating the adhesive label.
Terminals
2-pole and 4-pole terminals are used for connecting
external cables to the modules.

Restrictions:
*) only 1 module with fast pulses is possible;
only permissible on slot 2;
min. pulse duration :
- 2 ms, if pulse module 1 not fitted
- 5 ms, if pulse module 1 fitted
**) Subsequent mounting of a further pulse module
in module slot 1 can result in changed output values
for module 2!
(1) For M-bus with controller coupling, the CL read-
out can take up to 40 s
(2) Pulse length of the fast pulses min. 5 ms
(3) The first and second channel can be
parameterized individually
(4) The secondary address for both modules can
only be changed via module No. 1
Pulse module
Pulse module
Pulse output:
Channel 1,
Channel 2
The pulse module permits the output of pulses that
can be derived from the quantity of heat, the volume,
tariff register 1 or tariff register 2. Two channels are
available whose functions can be parameterized
with the PappaWin software.
Output takes the form of standard pulses or “fast
pulses”. The pulse duration is identical for channel 1
and channel 2.
Note: If two pulse modules are plugged, please note
the restrictions!
