Description
The key exchange unit (KEX) is used in an interlocking sequence to
link together other devices in the Prosafe range and caters to more
complex operating sequences.
The operating principle is such that no secondary keys can be
removed from the unit until all primary keys have been inserted,
rotated, and trapped. The primary keys remain trapped until all
secondary keys have been re-inserted, rotated, and trapped.
It is typically used in applications where there is more than one
access way to the hazardous area, and each access way must be open
at the same time. The key exchange unit accomplishes this by
allowing one or more keys to be inserted which then releases
multiple keys out.
A typical process may require a rotary key switch to turn a motor off.
The key from the rotary switch is removed and inserted into a KEX.
The KEX then releases three keys which would allow simultaneous
access to the hazard area through three different gates. This KEX is
described as 1 key in 3 keys out. The keys in are considered primary
codes, so the keys are not included in the KEX. The keys out are
considered secondary codes, so the keys are included.
