6.1.2. Supply Power for the Modules
The supply power must be stable within a range of 2 % of the nominal value.
For stable supply power with dynamic operation of high piezo loads, the power supply must
be equipped with a sufficiently dimensioned buffer capacitor. The required capacitance of
the buffer can be approximated as follows:
Buffer capacitance = 10 × piezo load
6.1.3. Amplifier Modules: Closing the Circuit
In order to feed the Control In signal (DC-Offset potentiometer and/or Control Input) into the
amplifier, short the following pins:
E-504, E-505, E-506, E-508  pin 2c to 4a
E-503  pin 2c to 4a; pin 10c to 12a; pin 18c to 20a
Otherwise the output voltage of the amplifier would go to its positive / negative limit.
