24V_S = Actuator supply
The 24V_S voltage level supplies:
• The digital outputs DO.. ,
• The connected actuators
• The VO24_IV sensor supply output.
The digital inputs DI12 – DI15 are connected to the reference potential 0V24_S as
these can be connected to the same connections as an alternative to the outputs.
To centrally deactivate the actuators of the plant, you can disconnect the 24V_S volt-
age level during operation, if required.
24V_P = Inverter supply
The 24V_P voltage level supplies the integrated inverter with 24 V.
Depending on the application, the 24V_P voltage level can be supplied by 24V_C or
24V_S (via jumpers at X29) or externally. The required jumpers are included in the
scope of delivery.
WARNING
Danger with applications with safe disconnection due to incorrect connection of the
safety relay or the safety controller.
Severe or fatal injuries.
• During safe disconnection, 24V_P must be connected over a suitable safety relay
or a safety control.
• If you use MOVIFIT
®
with the PROFIsafe option S11, observe the permissible
wiring diagrams as well as the safety conditions specified in the "MOVIFIT
®
MC /
FC – Functional Safety" manual.
• If you use MOVIFIT
®
with the safety option S12, observe the permissible wiring
diagrams as well as the safety conditions specified in the "MOVIFIT
®
MC / FC –
Functional Safety with Safety Option S12" manual.
Note that the integrated inverter is no longer supplied with 24 V in case of safe discon-
nection. This causes an error message.
