15.4 Analog input
Note
●
When running program 9, also set DIP switch SW4-3 on the outdoor unit PCB of the FDC out-
door unit to ON (see FDC series Technical Manual).
●
If there is no input voltage, e.g. due to a broken wire or open input, a frequency of 0 Hz is
transferred.
●
Analog input X3-S is only evaluated if a signal is applied to digital input X2b-D4 (see “5.1
Functions of analog input X3” on page 23).
●
Analog signal conguration must always begin at 0 V DC or 0 mA, to prevent signal distortion
due to electrical induction.
Cascading without signal overlap
The diagram below shows the control behavior of two CompTrol Interface expansion modules for
actuating two outdoor units each with a maximum frequency fmax Heating of 75 Hz without signal
overlap. The compressor frequencies are controlled by the analog signals and depend on the
outdoor unit models set via DIP switches S1-5 and S1-8. The compressor frequencies fmin, fmax
Heating, and fmax Cooling are permanently set for the outdoor unit in question.
