Line voltage compensation

This function is required if the output power is to be corrected automatically in the case of strong line voltage fluctuations.

To implement this function, a line-voltage sensing submodule must be plugged in to at least one central interface module in a network of several HCS724I heater controllers.

The correction factors are calculated and transferred to the PROFIBUS DP master. The DP master then distributes these values to all HCS724I DP slaves.

Voltage measurement for enhanced diagnostics

To enable voltage values to be measured for enhanced diagnostics, a line-voltage sensing submodule is required for each central interface module.

The determined voltage value is used for detecting faults in emitters connected in parallel.

Note:

The central interface module is only supplied from the factory without a line-voltage sensing submodule. If you want to compensate for line voltage fluctuations, you must order both modules (line-voltage sensing submodule and central interface module) and connect them together on site.
