Wiring example with a suitable hydraulics. AKAS is responsible for all safety related monitoring tasks
(at a Hex switch B8 B8 or F8 F8)
AKAS monitors both positions of the fast speed and slow speed state and requires:
in fast speed: at SGO = + 24 V and at SGS = 0 V
in slow speed: at SGO = 0 V and at SGS = + 24 V
During the switching over from one state into the other state, an enhancable switch-over time is tolerated.
