0...120 min S1 priority: How long the device waits before
(2* s) transfer sequence back to available S1 begins.
This delay is overridden by 'Override S2 Failure'
in case of S2 failure.
S2 priority: How long the device is keeping the
load on failed S2 although S1 is already
available.
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 S2
to S1.
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 S2
to S1.
0...60 min Enabled only when generator is in use.
(5* min) Generator cooling time, how long the device is
keeping the generator running without load
after returning to priority source.
0*...60 s Enabled only when any digital output is
configured as 'Load Shed'.
How long before the transfer from priority to
non-priority source the device activates load
shed signal.
0*...60 s Enabled only when any digital output is
configured as 'Elevator pre-signal'.
How long the device is keeping pre-signal
signal activated before transferring from
S1 to S2.
0*...60 s Enabled only when any digital output is
configured as 'Elevator pre-signal'.
How long the device is keeping pre-signal
signal activated after transferring from
S1 to S2.
0*...60 s Enabled only when any digital output is
configured as 'Elevator pre-signal'.
How long the device is keeping pre-signal
signal activated before transferring from
S2 to S1.
0*...60 s Enabled only when any digital output is
configured as 'Elevator pre-signal'.
