and programming interface (X5)
Optionally the following modules are allowed to be used:
Shutdown-switch-input
(terminals +51, -52
resp. +85, -86)
Mechanical digital feedback
(terminals Limit1 +51, -52
resp. Limit2 +41, -42)
The intrinsically safe circuits themselves are safe galvanically separated up to a voltage of 60 V. The
"Local interface for communication (LKS) and programming interface (X5)" is connected with the signal
circuit.
