Manual Integrator Supercal 531 06-06-2011 56
9. Special Functions
The special functions of the Supercal 531 can either be activated at the factory or with the service
software Prog531.
9.1 Status message of the transistor outputs
The Supercal 531 allows the transmission of the status messages to the transistor outputs. The
displayed statuses can be defined over the threshold values.
Example: the alarm output can be used via the control system for the immediate and exact moni-
toring of an important operation mode of the system.
9.2 Threshold values
The threshold value is the value which is used as limit for processing a signal, e.g. for a tariff
change or a control system. As soon as the value of the parameter drops below the minimum
threshold value or exceeds the maximum threshold value, the signal- or alarm output is activated.
Two threshold values can be parameterised over the optical interface or via the operator keys.
The following internal values/incidents can be used to define the thresholds:
Current flow
Current power
„Temperature high“ or „temperature low“
Temperature difference
Time window (consisting of date and time)
Occurrence of an error
Flow additional meter A1
Flow additional meter A2
9.3 Solar power systems and cooling systems
The Supercal 531 which originally has been calibrated for water also guarantees precise meas-
urement of glycol mixtures. The medium to be measured and its average mixing proportion are
parameterised acc. to the customer’s requirements. In this case, the integrator also processes and
calculates negative temperatures.
The dust- and splash-proof housing of protection class IP65 is also suitable for cooling systems.
Please follow the insulation regulations for cooling systems.
An official calibration is not possible for solar systems and cooling systems with glycol mixtures.
9.4 Tariff functions and/or status message signal
Besides the cooling-/heating tariff, the Supercal 531 disposes of various customer-specific tariffs
which can be defined over the respective threshold values.
They can be programmed over the optical interface or the M-Bus interface without damaging the
calibration seal.
Examples of different types of tariffs:
Tariff control by means of the current flow
Tariff control by means of the current power
Tariff control by means of the temperature low or temperature high
Tariff control by means of the temperature difference
Tariff control by means of the inner tariff time switch
Combined cold- /heat meter
The tariff functions are explained in detail in the annexe 16.2 Tariff Functions.
