xLogicSoft solution
The use of xLogic reduces the amount of switchgear. Thus, you save installation time and
space in the control cabinet. You may even be able to use as a smaller control cabinet.
With xLogic you can also switch off of the fans sequentially after the system is switched
off.
The circuit in xLogicSoft
The system is switched on and off at the inputs I1 and I2. The fans are connected to
outputs Q1 and Q2, the flow sensors are connected to the inputs I3 and I4. Blocks B07
and B10 are used to set the watchdog times after which the flow sensors should send a
signal to the fault output Q3.
