With active "safe standstill" function

Safety instructions for the installation of the "safe standstill" function
Only qualified personnel are permitted to install and set up the "Safe standstill"
ƒ
function.
All safety-relevant cables (e. g. control cable for the safety relay, feedback contact)
ƒ
outside the control cabinet must be protected, for instance, by a cable duct. Short
circuits between the single cables must be ruled out!
Wiring of the safety relay K
ƒ
absolutely vital.
The electrical reference point for the coil of the safety relay K
ƒ
with the protective conductor system (DIN EN 60204-1 paragraph 9.4.3). Only this
measure guarantees that the operation is protected against earth faults.
Internal voltage supply
For supplying the digital inputs (X5/E1 ... X5/E5, X5/ST1), a freely assignable digital
ƒ
output (e. g. X5/A1) must be firmly applied to HIGH level.
For supplying the analog inputs (X6/1, X6/2 and X6/3, X6/4), a freely assignable
ƒ
analog output (e. g. X6/63) must be firmly applied to HIGH level.
