Manual Integrator Supercal 531 06-06-2011 26
Alarm signal: 0101010101…
Transmission time: 2.2 seconds +/- 0.1
Total transmission time: If the time > 40 seconds or if X > 138 ms, a new wake up is sent.
6.1.2 Pulse input for volume measurement
The Supercal 531 allows the connection of slow and fast flow sensors. To this end, two specific
filters have been integrated (normal- or fast mode) which can be selected over the software
Prog531.
6.1.3 Two additional pulse inputs
The Supercal 531 features two additional pulse inputs (A1 and A2) to connect additional meters for
cumulated pulse counting. These two additional pulse inputs are integrated automatically in the M-
Bus, radio or optical telegram and transmitted.
Thus it is possible to connect water meters, electricity meters, gas meters or oil meters.
They are parameterised (normal and / or fast mode) ex factory over hardware bridges. Unless oth-
erwise defined in the order, the two additional pulse inputs are set to normal mode.
In case a subsequent change from normal to fast mode is necessary, the solder bridge respec-
tively the resistance (0 Ω) JP2 (A1) / JP3 (A2) on the main board has to be removed by authorized
personnel.
6.1.4 Two open-collector pulse outputs
Two open-collector outputs (B1 and B2) can be used to optionally display energy, volume, tariff 1,
tariff 2, alarm values and threshold values.
Maximum current per pulse output is 100 mA; maximum voltage is 30V.
They are parameterised (both in normal or fast mode) with the service software.
Fast pulse outputs are used e.g. for controlling system processors. In this case, the maximum
pulse frequency is 12 kHz.
These outputs are not isolated galvanically. When connecting to process systems, we always rec-
ommend using relay outputs.
6.1.5 M-bus communication
Besides the factory-assembled M-bus module up to two further communication modules can be
mounted.
The factory-assembled M-bus module is controlled by the microprocessor located in the integrator
upper part. The optional communication modules are equipped with an embedded microprocessor.
Thus it is ensured that up to three M-Bus inquiries for different applications can be processed and
answered at the same time.
The two additional pulse inputs are automatically integrated in the M-bus telegram and transmitted.
To clearly identify the two pulse inputs, it is possible to parameterise an identification or part num-
ber for each input.
The integrator Supercal 531 works with a variable data structure. For each M-bus output an indi-
vidual primary address as well as a baud rate can be parameterised.
The protocol of the optional communication modules with interface RS-232 also corresponds to the
M-Bus protocol.
In case of an M-Bus “application reset” the default settings are set acc. to standard EN1434.
