Possible slots for operator controls

●
When an operator control takes up or covers up multiple slots, the total number of slots is
reduced.
●
A maximum of two emergency stop buttons and a specific number of operator controls
can be installed.
●
An emergency stop button with a yellow ring 40 mm in diameter takes up the slot of an
operator control.

An emergency stop button with a yellow ring 60 mm in diameter covers up the adjacent
slots and therefore takes up:
–
Two slots when the emergency stop button is installed in an outer slot.
–
Three slots when the emergency stop button is installed between two slots.
●
An RFID reader can be installed in the free slots on the left or right. The reader covers
