Figure 11: Example for 0-10V signal output from the regulator. The corresponding SSR outputs must be set to the PWM function, and the
desired PWM modulation frequency must be set. The outputs SSR 4 to 6 generate the desired signal directly (but the signal may have a
significant output ripple at slow PWM modulation), SSR outputs 1 to 3 generate only PWM, so you must use external PWM/0-10V
converter to get the desired signal.

Figure 12: Connection of positive SSR anodes (typically A1 +) to an external DC source + 12V when the internal power supply of the
controller is heavily loaded. SSR control circuit can be normally powered by + 12V or + 5V terminals. We recommend the + 12V (must be
used if the control voltage >5V is required). However, using the two built-in relays, the voltage at the + 12V terminal can drop to + 8V
and will not fully drive the SSR 4 to SSR 6 outputs in the PWM / 0-10V function, and some of the built-in relays does not need to be
switched on. In this case, connect all SSRs to an external power source as shown in the figure. Firmware since version 1.5 already checks
the voltage drop at + 12V terminal and also enables software optimization of the built-in relay consumption. For details, see chapter
Measured parameters and statuses and chapter Other settings tab.
