Installation manual
6.2.4 Inputs
The signal level can be 5-24V DC/AC or 100- 240V AC. For 5-24V, the signal reference is connected to 3 and for
100-240V to 4. Potentials on the inputs cannot be mixed.
Note!
The I/O board will be damaged if the voltage on connection 3 is too high > 24V.
Connection 8 may be connected if the program is to pause, e.g. while detergent is being dosed.
The figure shows an example of engaging a 24V pause signal. The program will pause for as long as the pause sig-
nal remains activated (high).
