F-22 Mains failure duration (IPS)
With the default settings, each fault triggers a fault message. An
automatic restart is possible after the following fault messages
have occurred:
• Overcurrent (E01 to E04, up to four restart attempts within ten
minutes before a fault message is issued)
• Overvoltage (E07 and E15, up to three restart attempts within
then minutes, then fault signal)
• Undervoltage (E09, up to 16 restart attempts within 10
minutes, then a fault message is issued) a section
“Diagnostics and troubleshooting”, page 113
With PNU b01, specify the restarting behaviour.
With PNU b02 and b03, specify the behaviour on mains failure
(
a fig. 125 and fig. 126).
j Danger!
In the event of a fault, this function causes an automatic
restart of the RA-SP after the set delay when a Start signal
is applied (through AS-Interface
®
) or if an operating
direction is enabled in manual mode (selector switch).
Ensure that an automatic restart does not present a
danger for personnel.
