Controllers

3. Function test

n

  Disconnect sensors on terminals 3, 4, 5 and 6

n

  Short terminals by leads. Short terminals 3 and 5 by one lead, and 4 and 6 by the second 

one. After switching on, two control lights will turn on green (OK 3/5 and OK 4/6) and 
output-relays will be activated.

n

  In case of safety units with manual blocking, only one light will turn on. Press RESET in 

order to reset the safety unit.

n

  If terminals 3 and 4 or 5 and 6 are short, then both channels (K1 and K2 releases) will be 

deactivated.

n

  If we break connection on 3/5 terminals, K1 relay will be deactivated.

n

  If we break connection on 4/6 terminals, K2 relay will be deactivated.
