1.0 Operating and safety instructions
This manual must be read carefully and all instructions must be followed
before starting up the EXKOP

Any modification or careless installation of the components can result in
failure of the entire system. This can result in explosion propagation which can
cause the destruction of the equipment. The devastating effects of such an
explosion can also endanger human life.
The operating diary which contains the log of all events happened and the access
code for the EXKOP
®MINI
Safety Controller as well, must be kept by the designated
plant safety representative.
The monthly test function (see section 6) must be carried out by the designated plant
