During the output of an error message, the number of output pulses indicates the error:
Pulse Error message
1 Voltage supply outside of the valid value range
2 Output control Open faulty
3 Output control Close faulty
4 Data transmission with microcontroller faulty
5 ISK transmission error

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.
