0*...60 s
0...60 s (2* s) S1 priority: How long the device is waiting S1
recovery before starting transfer sequence
to S2.
S2 priority: How long the device is keeping the
load on failed S1 although S2 is already
available.
0...60 min S1 priority: How long the device is keeping the
(2* s) load on failed S1 after S2 becomes available.
S2 priority: How long the device waits before
transfer sequence back to available S2 begins.
This delay is bypassed by 'Override S1 Failure'
in case of S1 failure.
0*...300 s Enabled only when any digital output is
configured as 'Pre-transfer Signal'.
How long the device is keeping pre-transfer
signal activated before transferring from S1
to S2.
0*...300 s Only delayed transition I-O-II type. How long
the switch is stopped at position O while
transferring from S1 to S2 or from S2 to S1 and
the original source is not completely down.
Center-OFF delay is bypassed in case all phases
are missing from the original source which we
are leaving.
0*...300 s Enabled only when any digital output is
configured as 'Pre-transfer Signal'.
How long the device is keeping pre-transfer
signal activated after transferring from S1
to S2.
0...60 s (2* s) S1 priority: How long the device is keeping the
load on failed S2 although S1 is already
available.
S2 priority: How long the device is waiting S2
recovery before starting transfer sequence
to S1.
