P7 terminal strip, terminals 1 to 4:
▪
The function of the two volt-free relays (NO) can be parameterised via the
control panel.
P7 terminal strip, terminals 5 to 10:
▪
Analog signals from a higher-level control station must be electrically isolated
when they are transmitted to PumpDrive, for example by using isolating
amplifiers.
▪
If an external voltage or current source is used for the analog inputs, the ground
of the setpoint or sensor sources is applied to terminal P7:10.
▪
The +24 V DC voltage source (terminals P7:5 and P7:7) is used as the power
supply for the actual value sensor if PumpDrive is in closed-loop control mode.
▪
Alternatively, analog input 2 can be connected to the mains/motor/PTC terminal
strip. In this case, do not assign the input on terminal strip P7:6.
