6.2 Signal indicators
During the output of an error message, the number of output pulses indicates the error:
6.3 Connection terminals
Uin, Gnd:
DC voltage supply for device variant ISK 77 E. A positive cable is connected to Uin, and the negative cable is
connected to Gnd.
B1, B2:
AC or DC voltage supply for device variant ISK 77 R or ISK W. The polarity of the supply voltage is not critical.
