Power failure monitoring (UVO)
Description
The "Power Failure Monitoring (UVO)" function block is activated via the plug. This is
performed via an external voltage relay that is connected to the function block via the binary
inputs of SIMOCODE pro.
Sequence (see timing charts below):
1. All contactors (QE) are disconnected immediately after the monitoring relay has been
operated/the input has been activated (UVO).
2. If the voltage is restored within the "power failure time", the motor will be reset to its
previous state. This can either take place immediately or with a time delay (restart time
delay).
3. If the "power failure time" elapses before the voltage returns, the device signals a fault
(UVO fault).
Prerequisite: The SIMOCODE pro control voltage is buffered and not interrupted.
In total, one "Power Failure Monitoring" function block is available for the pro V basic units.
